Abstract
Description
[0001] ACIDIC DRY FREE-FLOWING FOOD-BORNE TOXIN REDUCING COMPOSITION
[0002] TECHNICAL AREA
[0003] The present invention relates to an acidic dry free-flowing composition for reducing food-borne toxins according to claim 1 , and further discloses a method for its production. Preferably, the composition can effectively reduce acrylamide, furan and hydroxymethylfurfural (HMF) contained and / or formed in thermally processed food-items, employing a dualcomponent mixture, without the use of compounds derived from genetically modified organisms (GMOs) and is free of additional additives such as leavening agents and coatings.
[0004] STATE OF THE ART
[0005] Food-borne toxins, which are harmful substances contaminating food, can lead to a variety of illnesses upon consumption. These detrimental substances can originate from numerous sources, such as bacteria, molds, viruses, and sometimes even the food products themselves. Certain food-borne toxins are naturally present, for example, some mycotoxins that are produced by molds. Others, however, result from microbial infection or food spoilage. Furthermore, there is a category of food-borne toxins that develop during food processing. In this case, starting materials, initially non-toxic, undergo transformations that lead to the creation of toxic compounds, thus underlining the importance of proper food processing and handling practices. A prime illustration of the generation of food-borne toxins during food processing emerges when heat treatment is applied to a variety of food products.
[0006] Acrylamide (C3H5NO) is a potentially harmful compound that forms in certain types of food during high-temperature cooking processes, such as frying, roasting, and baking at high temperatures especially above 180°C. The formation of acrylamide is predominantly due to a process known as the Maillard reaction, which is a chemical reaction between amino acids and sugars that occurs when food-items are heated. More specifically, acrylamide forms from a reaction between the amino acid asparagine and reducing sugars such as glucose and fructose present in food. Starchy foods, such as potatoes and grain products, are particularly prone to acrylamide formation when they're cooked at high temperatures, due to their higher levels of asparagine and reducing sugars, the two key ingredients for acrylamide formation. Other factors effecting high levels of acrylamide in foods are a low moisture content, a high pH level and increased cooking durations. Another compound formed during thermal treatment of carbohydrate-rich foods is 5-Hydroxymethyl 2-furfural (HMF; C6H6O3). Its formation is particularly associated with the Maillard reaction and the acid-catalyzed dehydration of hexoses such as glucose and fructose. Factors like high temperatures and low pH significantly influence its creation. HMF is prevalent in foods like honey, fruit juices, baked goods, and heat-treated milk, with quantities varying based on the food type and preparation method. Another compound associated with the Maillard reaction and known as a thermally induced food-borne toxin is furan (C4H4O), along with its derivatives such as 2-methylfuran (CsHsO) and 3-methylfuran (CsHsO). Beyond the Maillard reaction, furan can form through alternative pathways such as the thermal degradation of natural food components like vitamin C, as well as through the oxidation of polyunsaturated fats.
[0007] Ever since the detection of food-borne toxins such as acrylamide, HMF, and furans in the 20th and 21 st century, their toxicity especially in terms of carcinogenicity and associated risks have been well-established. Thanks to the continual improvement in analytical detection methods, it has been revealed that these substances are prevalent in a magnitude of products in our food supply. As a result, chronic exposure to these toxins is almost unavoidable, leading to both a rising consumer demand and a regulatory push aiming to reduce the level of these harmful compounds in ourfood. In April 2018, the European Commission Regulation (EU) 2017 / 2158 established mitigation measures and benchmark levels for the reduction of acrylamide in food, with binding thresholds expected for 2024. Despite the absence of formal binding thresholds for acrylamide in the United States, food producers still face challenges, as acrylamide has been classified as a potential carcinogen under California's Proposition 65 since 1990, necessitating a warning label on products sold in California that contain acrylamide, wherefore producers aiming to penetrate the U.S. market must inherently adhere to these specifications. Other regions, including Australia, New Zealand, and China, have started scrutinizing the issue of food-borne toxins. Consequently, future regulations intended to limit their presence in food can be anticipated. Regarding furan and HMF, ongoing risk analyses are being conducted globally, and the increasing body of evidence suggests that future measures may be instituted to limit these compounds in food. For instance, the European Food Safety Authority (EFSA) conducted an extensive evaluation of the health risks associated with furan in food and published its findings in 2017, whilst the Food and Drug Administration (FDA) in the United States progressively formulated a Furan Action Plan over the span of 2005 to 2007.
[0008] To tackle food-borne toxins that arise from thermal processing, both legislators and private companies have advocated and developed numerous mechanical and physical strategies for reducing these substances in food. These include pretreatment measures like cold storage of produce to reduce sugar content or blanching, soaking, and rinsing to eliminate asparagine, a key precursor to acrylamide; adaptations to the cooking process, such as employing lower temperatures, reducing cooking durations, or utilizing methods like microwave cooking or steaming; and post-treatment techniques like vacuum application to remove acrylamide from the final product. However, these strategies often necessitate investment in additional equipment and modifications to existing processes and may not be universally applicable. Therefore, many food producers, particularly those dealing with acrylamide-prone products, have advocated for incorporating ingredients into their recipes that can decrease food-borne toxins in the final product, eliminating the need for substantial process alterations and investments.
[0009] Enzymatic strategies, as outlined in the patent document US20070166439A1 and available commercially through companies like Novozymes (Acrylaway®) or DSM (PreventASe®), are among the most favored ingredient to reduce acrylamide in food. Alternatively, asparaginase rich baker’s yeast products commercially available through companies like Kerry Group (Acryleast™) utilize the same mode of action. These strategies employ asparaginase to lower the quantity of asparagine, a precursor to acrylamide, in foods. Nevertheless, asparaginase, is produced using genetically modified organisms (GMOs), limiting its use in foods requiring a GMO-free label, as well as in organic products, both in the United States and the European Union. Furthermore, despite the need for only small quantities, asparaginase remains an expensive ingredient. Its application also necessitates longer pretreatment times in the food substrate to ensure its effectiveness, increasing stand times, further escalating the production costs for food manufacturers. Moreover, the effectiveness of enzymes is subject to environmental factors such as pH and temperature, leading to a high dependency on precise storage and transport temperatures, as well as adequate food product formulations for optimal performance, rendering the unpredictability and high variance of asparaginase results, adding to the complexity of this solution. Despite some asparaginase rich baker’s yeast products being available in GMO-free versions intensified application downsides prevail whilst complications through the leavening activity of the baker’s yeast can arise, rendering this product unsuitable for a multitude of bakery products. The patent document US20070141225A1 seeks to enhance the reliability of asparaginase by integrating additional components such as multivalent cationic salts, food acids, food bases, and amino acids. However, given that asparaginase is the primary ingredient, the previously noted challenges associated with asparaginase still persist. Moreover, the patent does not allow the product to be offered as a premix. This limitation arises because many of the outlined secondary components, including the specified food acids and bases, are incompatible with asparaginase in a premix, as asparaginase is susceptible to environmental changes, such as shifts in pH, which can compromise its stability and effectiveness.
[0010] The inclusion of multivalent cationic salts, as proposed in patent documents US20050079254A1 and US20070212450A1 , is intended as a method to replace the use of enzymes in food as acrylamide reducing agents. However, the use of salts and double salts alone presents limited effectiveness in reducing acrylamide formation. This limitation stems from the fact that only a restricted number of Maillard pathways are impacted, given that these additions do not induce any change in the environmental pH conditions. Moreover, these patent documents solely address the issue of acrylamide in food products while neglecting other harmful substances such as hydroxymethylfurfural (HMF) and furan. Patent documents JP2005021150A and W02004075655A2 discuss methods for reducing acrylamide levels in food products by using a mixture of various amino acids and their salts. Although the patents propose potential benefits, they include a composition that integrates a mix of amino acids, some of which carry high costs. This aspect detracts from the appeal of the solution and could benefit from the introduction of a secondary component that utilizes more economically viable compounds. An additional limitation is the fact that several amino acids named in the patents lack approval for use in food production, with none of the products mentioned for use in organic goods within the European Union, significantly restricting the feasibility of the suggested solution in this crucial market. The patents’ use of certain amino acids like glutamine may exacerbate the issue, as amino acids that contain an amide group in their side chains can contribute to the Maillard reaction, potentially leading to an increase in acrylamide formation. Further, the patent documents only address the issue of acrylamide in food products, overlooking other harmful substances like hydroxymethylfurfural (HMF) and furan. These limitations drastically reduce the patents utility and the range of their potential applications.
[0011] Patent document DE102019113073A1 proposes utilizing a multivalent cationic carbonate as a primary component and an acidic compound as a secondary component to reduce acrylamide in food. However, the use of carbonates as the primary component has major issues:
[0012] 1. Carbonates lead to an increase in the pH level of food, posing a risk of amplified acrylamide formation and rendering the secondary acidic component less useful.
[0013] 2. Carbonates (component 1 ) exhibit a tendency to react with acidic compounds (component 2), resulting in the release of carbon dioxide. The patent proposes a fat coating to counteract this issue. However, this solution amplifies production costs and compromises product efficiency, as the fat coating only melts upon the application of heat, thus delaying efficacy in the food product.
[0014] 3. Carbonates are not universally applicable, especially in food mixtures not requiring leavening orthose employing yeast for leavening. This restriction challenges manufacturers already dealing with limited control over leavening power of their products.
[0015] Further, the patent document only addresses the issue of acrylamide in food products, overlooking other harmful substances like hydroxymethylfurfural (HMF) and furan. Therefore, there is still a significant need for a more effective strategy that can manage the presence of harmful substances in food production without compromising process efficiency and compound efficacy.
[0016] Patent documents KR102234633B1 and KR20090062381A propose the addition of different compounds including dicarbonyl trapping agents, reducing agents, water-soluble antioxidants, fat-soluble antioxidants, and proteins to reduce furan levels in food. However, the reliance on substances including epicatechin (EC), epigallocatechin gallate (EGCG), caffeic acid, ferulic acid, and coenzyme Q10 to curb furan formation, particularly in juices and coffee, poses significant challenges. Regulatory restrictions in many parts of the world, including the European Union, do not permit the use of these substances in food. Additionally, the high cost and limited availability of these products further exacerbate the problem. While the patent mentions reducing other Maillard reaction products, it falls short in addressing the formation of acrylamide and HMF. Given the crucial importance to eliminate these compounds to ensure food safety, this reduces the patent's urgency and utility. Hence, a more effective strategy that balances food safety, process efficiency, and compound economics in managing harmful substances in food production is still in high demand. OBJECT OF THE INVENTION / TECHNICAL PROBLEM
[0017] Amid rising consumer health consciousness and mounting regulatory pressures globally, the food industry faces an urgent need fora practical and efficient solution to mitigate food-borne toxins. Of particular concern are toxins such as acrylamide, furan, and hydroxymethylfurfural, of which a reduction is pivotal to adhere to food safety and quality standards. There exists an imperative necessity for a solution that surpasses the limitations of current alternatives to address these significant challenges effectively. Hence, the object of invention is to create an effective, cost efficient and robust solution, which is free of GMOs, free of additional additives such as leavening agents and coatings, easy and economical to implement, applicable to a wide array of products and adaptable to a variety of food-borne toxins.
[0018] A simple and cost-effective manufacturing process is also necessary, using readily available materials and requiring no additives or catalysts for large-scale economic synthesis. Moreover, ensuring easy usability that does not necessitate substantial alterations in the existing industrial processes is fundamental, as it would facilitate a swift and efficient adoption.
[0019] SOLUTION
[0020] The object of invention has been solved through an acidic composition according to claim 1 for the use as additive in thermally processed food-items, employing a at least dual-component mixture, comprising a first component, preferably an a C2-Cs mono- and / or di- and / or tri-valent carboxylic acid derived salt and / or oxyacid derived salt, and a second component, preferably an organic C2-Cs carboxylic acid, wherein the composition is leavening agent-, GMO- and coating- free and reduces food-borne toxins present and / or produced during thermal processing of food-items when applied.
[0021] In addition, the inventors disclose a process for preparing a composition according to claim 13, its use in the preparation of food-items according to claims 15-19, and a process for preparing toxin-reduced food-items using the composition according to claim 14.
[0022] Further advantageous embodiments and further embodiments result from the subclaims as well as from the description with reference to the figures.
[0023] GENERAL ADVANTAGES
[0024] Surprisingly, it has been discovered that incorporating a food additive acid composition according to the current invention into food products can effectively and robustly reduce food-borne toxins such as acrylamide, furan, and HMF, either individually or simultaneously, without the need for compounds derived from genetically modified organisms. This finding opens up new markets where previous solutions involving GMO derivatives, prohibited ingredients in food, or unfeasible or uneconomical methods were not applicable. By concentrating on a solution solely aimed at reducing food-borne toxins, producers are given the flexibility to incorporate any other functional ingredients at the necessary dose into the final product, without having to settle for subpar results in other domains.
[0025] The use of a buffered carboxylic acid system by incorporating a carboxylic acid or oxy acid salt as the first component and a carboxylic acid as a second component of the composition lowers the pH of the food-item, further suppressing the thermic induced Maillard reaction unlike when basic additives such as but not limited to carbonates are used as exemplified in the prior art.
[0026] Additionally, the herein disclosed composition is specifically designed not to contain any leavening agents, such as carbonates and yeasts, which are typically employed in the prior art to reduce acrylamide. The inclusion of these agents often leads to an unintended and unpredictable leavening of food products, making them unsuitable for foods that do not require leavening, a specific leavening style, or a precisely calibrated leavening strength. Further, carbonate-based approaches which include an acid component are unsuitable for soaking applications, as these would neutralize in solution.
[0027] Another advantage pertains to the distrust towards GMO-modified food, which as per recent surveys, is still met with skepticism by a significant portion of the public in many markets. Beyond the economic benefits presented by this innovation, it could also bolster public health by diminishing the presence of hazardous food-borne toxins. The use of the composition outlined in the current invention could potentially gain wider acceptance, thereby contributing positively to the general wellbeing of the public.
[0028] DETAILED DESCRIPTION
[0029] The inventors provide an acidic composition, preferably a food additive acid composition as additive in thermally processed food-items, employing an at least dual-component mixture, comprising a first component comprising at least a salt that comprises at least an anion, preferably a C2-C6 mono- and / or di- and / or tri-valent carboxylic acid derived anion and / or oxyacid derived anion, and at least a metal cation; and a second component comprising an acid, preferably an organic C2-C6 carboxylic acid, wherein the composition is leavening agent-, GMO- and coating-free and reduces food-borne toxins produced during thermal processing, preferably in a temperature range between 80 and 400°C, of food-items when applied.
[0030] In particular, the inventors provide an acidic dry free-flowing food-borne toxin reducing composition (sometimes also referred to as formulation), as additive in thermally processed food-items, employing an at least dual-component mixture, comprising or consisting of i. a first component comprising or consisting of a salt, preferably 1 or 2 salts, wherein the salt comprises or consists of an anion, wherein the anion is a C2-C6mono- and / or di- and / or tri-valent carboxylic acid derived anion and / or oxyacid derived anion, wherein the anion is selected from the group consisting of C2-C6mono-, di-, tricarboxylates, phosphates, sulfates, sulfites; wherein the C2-Cs mono-, di-, tricarboxylates are preferably selected from the group consisting of acetate, propanoate, lactate, citrate, malate and tartrate; and a metal cation, wherein the metal cation is selected from the group consisting of sodium (Na+), potassium (K+), calcium (Ca2+) ferric iron (Fe3+), or a mixture thereof, preferably the group consisting of sodium (Na+), potassium (K+) and calcium (Ca2+), and ii. a second component comprising or consisting of a C2-C6 mono- and / or di- and / or tri-valent carboxylic acid, wherein the C2-C6 mono- and / or di- and / or tri-valent carboxylic acid is preferably selected from the group consisting of acetic acid, propanoic acid, lactic acid, citric acid, malic acid, tartaric acid, glycine, cysteine, leucine, and glutamic acid or a mixture thereof, most preferably from the group consisting of acetic acid, propanoic acid, citric acid; wherein the mass ratio of the second component to the first component is in the range of 1 :19 to 2:3, wherein the composition comprises

This advantageously allows for a beter dosing and application of the composition in a broad range of thermally processed food-items which share the risk of developing food-borne toxins during thermally processing. Particularly, these compositions can be stored and dosed as free-flowing powders, facilitating safer transport, homogenization and more precise dosing. This can be achieved either by directly mixing the composition with the components of the untreated food-item or by dissolving the composition in a liquid, preferably an aqueous liquid, and soaking the untreated food-items in the resulting liquid composition.
[0034] In a particularly preferred embodiment of the current invention, the composition consists of a first component consisting of a salt, preferably 1 or 2 salts, wherein the salt comprises or consists of an anion, wherein the anion is a C2-C6mono- and / or di- and / or tri-valent carboxylic acid derived anion and / or oxyacid derived anion, wherein the anion is selected from the group consisting of C2-Cs mono-, di-, tricarboxylates, phosphates, sulfates, sulfites; wherein the C2-Cs mono-, di-, tricarboxylates are preferably selected from the group consisting of acetate, propanoate, lactate, citrate, malate and tartrate; and a metal cation, wherein the metal cation is selected from the group consisting of sodium (Na+), potassium (K+), calcium (Ca2+) ferric iron (Fe3+), or a mixture thereof, preferably potassium (K+) and / or calcium (Ca2+), and a second component, consisting of a C2-Cs mono- and / or di- and / or tri-valent carboxylic acid, preferably selected from the group consisting of acetic acid, propanoic acid, lactic acid, citric acid, malic acid, tartaric acid, glycine, cysteine, leucine, and glutamic acid or a mixture thereof; and comprises 0.0wt% formate and carbonate salts (leavening-agent free), 0.0wt% compounds derived from GMOs (GMO-free), and 0.0wt% coating or separating agents (coating-free). In this advantageous embodiment, the composition consists exclusively of the first component, made up of salts, and the second component, an organic C2-C6carboxylic acid, with exception of the common technical impurities associated with the production of these salts and acids. This represents a preferred embodiment of the invention, wherein no formate, carbonate, compounds derived from GMOs nor separating components are needed in order to provide an acidic, dry, free flowing food-borne toxin reducing composition, which simplifies the production, improves dosing and application as well as storage and quality control of the composition.
[0035] In a most preferred embodiment, the first component consists of 1 or 2 salts, wherein the salt consists of an anion, wherein the anion is selected from the group consisting of acetate, citrate, and sulfite; and a metal cation, wherein the metal cation is selected from the group consisting of sodium (Na+), potassium (K+), calcium (Ca2+) or a mixture thereof, more preferably from potassium (K+) and / or calcium (Ca2+), and the second component consists of a C2-Cs mono- and / or tri-valent carboxylic acid selected from acetic acid and / or citric acid.
[0036] In a most preferred embodiment, the first component consists of 1 or 2 salts, wherein the salt consists of an anion, wherein the anion is selected from acetate and / or citrate, and a metal cation, wherein the metal cation is selected from the group consisting of sodium (Na+), potassium (K+), calcium (Ca2+) or a mixture thereof, and the second component consists of a C2-Cs mono- and / or tri-valent carboxylic acid selected from acetic acid and / or citric acid.
[0037] In a preferred embodiment, the first component consists of at least a salt that comprises at least an anion, preferably a C2-Cs mono- and / or di- and / or tri-valent carboxylic acid derived anion and / or oxyacid derived anion, and at least a metal cation. In an alternative embodiment, the salt consists of at least an anion, preferably a C2-Cs mono- and / or di- and / or tri- valent carboxylic acid derived anion and / or oxyacid derived anion, and at least a metal cation.
[0038] In a preferred embodiment, the second component consists of an acid, preferably an organic C2-C6carboxylic acid.
[0039] The present invention provides a solid composition prepared as a powder that exhibits good flowability (free-flowing). The flowability describes the relative mobility of a bulk of particles among neighboring particles or refers to the ability of a powder to flow.
[0040] The obtained good flowability of the powdered compositions of this invention beneficially facilitates good powder product quality, manufacturing efficiency, transport security and storage in the broad field of powder processing industries. Amongst the general affect for the flowability like the bulk density and the cohesion properties of the component within the inclusion compound as discussed above, the particle size and the particle size distribution have a major influence on the flowability of powders (compare Baker et al., 1979) as discussed below.
[0041] The particle size and particle size distribution serve as suitable indicators for the flowability for the acidic dry free-flowing food-borne toxin reducing composition. The particle size of a powder compound is typically defined by the mean particle diameter dav, which is the diameter of most of the particles present for a given particle-size distribution of a powder. Typically, the mean particle diameter davof the free-flowing powders comprises mean particle diameter 10 pm < dav2 500 pm, preferably according to the invention is a mean particle diameter in the range of 20 pm < dav2300 pm, more preferably according to the invention is a mean particle diameter in the range 50 pm < dav2 250 pm.
[0042] Next to the particle size, the particle size distribution serves as a suitable indicator for the flowability of the acidic dry free- flowing food-borne toxin reducing composition. The particle size distribution of a powder composition is generally described by the mean particle diameter (dxo), which defines the portions of particles with a given diameter smaller or larger than the value X0VOi%.
[0043] The particle diameter distribution dso of the composition of invention may comprise 10 pm < d50 < 800 pm, preferably comprising 10 pm < d50 < 500 pm, in particularly 20 pm < d50 < 300 pm, and is more preferably selected from 50 pm < d50 < 250 pm.
[0044] The therein defined particle diameter distribution represents a low dispersity of the particle size of the free-flowing powder of invention. A low particle size dispersity as an essential factor for the flowability of the composition of the invention beneficially facilitates good powder product quality. If the composition of the invention is for example applied in the bakery industry, the powder flow behavior dictated by the particle size distribution facilitates e.g. a defined weight bottling and content uniformity of bakery products during processing.
[0045] According to the invention a narrow size distribution is beneficial and at least 50% of weight, preferably at least 90% of the powdered acid loaded salt carrier has a particle diameter less than 450 pm. Therein described narrow size distribution is defined by the d90. The particle diameter distribution dgo of the compound of invention comprises 10 pm < d90 < 1.000 pm, is preferably chosen from 50 pm < d90 < 800 pm, is more preferably selected from 150 pm < d90 < 450 pm.
[0046] In a preferred embodiment, the first component consists of one salt. In another preferred embodiment, the first component consists of two salts. In some preferred embodiments, a salt comprises or consists of 1 or 2 salts.
[0047] In a preferred embodiment, the salt comprises or consists of one anion, preferably a C2-Cs mono- and / or di- and / or tri- valent carboxylic acid derived anion and / or oxyacid derived anion and at least a metal cation.
[0048] In other embodiments the salt comprises or consists of two anions, preferably a C2-Cs mono- and / or di- and / or tri-valent carboxylic acid derived anion and / or oxyacid derived anion and least a metal cation.
[0049] In the spirit of this invention, the food additive acid composition, may be also referred to as composition, acidic composition or composition in accordance with the current invention.
[0050] A salt comprising at least an acid derived anion in the spirit of the current invention refers to a salt derived from the partial and / or complete neutralization of an acid with a metal and / or metal base. Preferably, the formed metal acid salts are acidic, neutral, or only slightly alkaline. Carboxylates are anions derived from carboxylic acids.
[0051] Anions are negatively charged ions formed when atoms gain electrons, commonly associated with nonmetals, and play a key role in acids. Cations are positively charged ions formed when atoms lose electrons, typically associated with metals, and contribute to the formation of salts. Acids are substances that release hydrogen ions (H+) when dissolved in water, with anions being crucial for their acidic behavior. Metals tend to form cations by losing electrons in chemical reactions, often leading to the creation of ionic compounds and salts. In the spirit of this invention, anions are regarded as acids which have lost at least one hydrogen ion and therefore having at least one negative charge and cations are regarded as metals with a positive charge. Preferably, an acid is completely neutralized, meaning that all acidic hydrogen atoms are replaced by metal cations. In an aspect related to organic acids (carboxylic acids), if an acid is mono-carboxylic, the resulting anion is mono-charged (monocarboxylate), if an acid is di-carboxylic, the resulting anion is di-charged (dicarboxylate), if the acid is tricarboxylic the resulting anion is tri-charged (tricarboxylate). Metal cations are positively charged ions.
[0052] An acidic substance is a chemical compound with a pH value in aqueous solution below 7. The pH scale ranges from 0 to 14, with 7 being neutral. Solutions below pH 7 are acidic, while that above pH 7 are alkaline or basic.
[0053] The addition of C2-C6 monocarboxylic, dicarboxylic, or tricarboxylic acid preferably substituted with an alkyl, amino, hydroxy, and sulfhydryl group, has been observed to decrease the levels of acrylamide, furan, and HMF in food. These acids, in a broader sense, are substances that donate protons (H+ions) and can lower the pH of a solution. pH is a measure of acidity or alkalinity based on the concentration of hydrogen ions.
[0054] When an acid is added to food or any other substance, it can modify its pH. The strength of the chemical bound hydrogen determines the strength of the acid and present in sufficient concentration, it can significantly decrease the pH, making the substance more acidic. In Oxyacids, the strength of the H-O-bond and the stabilization of the negative charge by the structure determine the strength. Organic acids tend to have higher associated pH values than mineral acids, a class of inorganic acids.
[0055] A substance, mixture or composition in accordance with the current invention is acidic when the pH-Value of a dilute solution, preferably 10 wt%, of the mixture in water is below pH = 7, more preferably below pH = 6, most preferably below pH = 5.5.
[0056] A carboxylic acid in the spirit of the current invention is any substance containing at least one carboxyl functional group (- COOH), a monovalent contains one, a divalent two and a trivalent acid contains three carboxyl functional groups.
[0057] Oxyacids, also known as oxoacids, are a type of acid that contain oxygen, hydrogen, and one or more other elements. These acids are characterized by the presence of one or more oxygen atoms bonded to a central atom (usually a nonmetal). They can have several H-O-groups, which influence their acidity.
[0058] In the spirit of the current invention, all oxyacids follow this general structure formula: (HO)nXR, wherein n is a natural numbers 3 and X is an atom ora group of atoms with exception of C, e.g., carboxylic acids and carbonic acid are excluded.
[0059] GMO stands for genetically modified organisms. It refers to any living organism whose genetic material (DNA) has been altered by genetic engineering techniques. These changes are made in a laboratory to introduce certain traits or characteristics that may not occur naturally in the organism through conventional breeding methods. GMO foods, also referred to as genetically modified (GM) foods, are products derived from genetically engineered plants or organisms. These foods are produced by inserting or removing certain genes from the DNA of plants, animals, or microorganisms.
[0060] GMO-free means that no component of the composition, especially preferably the first and second component are not produced with and / or derived from a GMO modified organism. Controversy over safety, environmental impacts, and potential human health effects has led many consumers to be critical of food-items containing or produced from GMOs, resulting in an economic advantage to the composition. In some preferred embodiments, the individual compounds specified in the invention offer exceptional value due to their readily available and cost-effective nature. Moreover, the disclosed compounds are available as non-GMO versions, which aligns with the increasing consumer demand for GMO-free options.
[0061] Consumer demand for GMO-free options has been on the rise, reflecting a growing preference for products that are free from products derived from genetically modified organisms (GMOs). This trend highlights the increasing importance of offering organic products that are guaranteed to be free of GMOs. GMO, or genetically modified organism, refers to any organism whose genetic material has been altered using genetic engineering techniques. These modifications involve introducing genes from one organism into another, often with the aim of enhancing desirable traits such as resistance to pests or increased crop yields. However, concerns have been raised regarding the potential long-term impacts of GMOs on human health and the environment. To cater to the growing demand for GMO-free products, it is essential to employ a composition that exclusively utilizes compounds derived from non-genetically modified organisms in both components according to claim 1 of this invention.
[0062] Organic products, in particular, are expected to be free from GMOs and their derivatives. Organic farming practices prioritize the use of natural methods and avoid synthetic chemicals, as well as products derived from genetically modified organisms. Organic certification standards mandate that products labeled as organic must adhere to stringent criteria, including being free from GMOs and GMO derivatives. The significance of this composition becomes evident when considering products derived from GMOs, such as asparaginase, which are not permitted in organic food production. Consequently, organic producers may encounter challenges in meeting the required thresholds for food-borne toxins without employing the composition disclosed in this invention.
[0063] Coatings may refer to any additional component used to separate the first and second component and provides the means to create a physical barrier between the two components and thus preventing a reaction between the two. An example for a coating is described in patent specification DE102019113073A1 to separate a carbonate salt from an acid component. This has the disadvantage that additional costs and steps are required during production, the composition is not active immediately but only after thermal activation, and it must be stored at low temperatures.
[0064] Advantageously, the composition in accordance with the current invention does not require any coating or separating agent, since the composition is stable after the blending process according to the method of preparation and can be stored under ambient conditions. This increased stability allows for reduced transportation and storage costs. In addition, the mixture is instantaneously effective and does not require any onset time due to the melting of the coating layer. Furthermore, this allows for treatment of a broader class of food-item.
[0065] Thermally processed food-items refer to any food-item which is heated, preferably between 80 and 400°C, during its preparation or production. Examples may include, but are not limited to, bakery and extruded products, such as breads, wafers, crackers, cookies, biscuits, breakfast cereals and rusks, vegetable-based, legume-based, nut-based, and fruitbased products, hot and cold beverages and syrup-like substances including coffee, fruit juices, alcoholic beverages, and honey.
[0066] In a preferred embodiment, the first component comprising a salt comprising at least a C2-C6mono- and / or di- and / or trivale nt carboxylic acid derived anion and / or oxyacid derived anion. This has the technical advantage that shorter carboxylic acids (C-i) can be decomposed eitherthermally or acid-induced, e.g., to carbonate or formate salts, making them unsuitable for many foods because the structure is destroyed, although gas evolution and CO formation can be a production risk. In addition, salts derived from longer acids (>C6) are usually more costly, non-polar or surfactant-like in behavior and therefore incompatible with many foods. The chosen carboxylic acids therefore have an economic advantage.
[0067] In a preferred embodiment of the current invention, the carboxylic derived acid anions (also referred to as anions) are natural occurring. These anions are usually biocompatible, which has several advantages. Furthermore, biocompatible anions from sustainable production are environmentally friendly and promote environmentally conscious food production. Finally, these anions, which are naturally derived and familiar to consumers, lead to greater acceptance and regulatory compliance.
[0068] In a preferred embodiment, the second component comprises or consists of an organic C2-C6 carboxylic acid. An organic acid in the spirit of the present invention is a compound containing one or more carboxyl (COOH) functional groups and having the general chemical formula R-COOH, where R represents a hydrocarbon group. It exhibits acidic properties by releasing hydrogen ions (H+) in solution.
[0069] In a preferred embodiment of the current invention, an organic carboxylic acid in the spirit of the invention may be a C2-Cs carboxylic acid corresponding to a C2-Cs carboxylic acid anion comprised by a salt comprised by the first component. Therefore, in some preferred embodiments, the first and second component may be derived from the same acid. This may have regulatory, procedural, cost and supplier advantages.
[0070] In an especially preferred embodiment, wherein the first and second component are derived from the same C2-Cs carboxylic acid the composition may be prepared by partial neutralization of C2-Cs carboxylic acid, either in concentrated form, preferably 90-99%, or in solution, preferably 10-90 wt% dissolved acid in a liquid, preferably water, by adding a metal or a basic metal salt, such as a metal hydroxide, metal hydride, metal carbonate and / or metal hydrogen carbonate.
[0071] Advantageously, in some embodiments of the current invention, the composition may form a buffered solution, thus stabilizing the pH value in a slightly acidic medium. This has the technical advantage that the pH is stable in a number of food-items, thus reducing the generation of base promoted food-borne toxins. This is because salts of weak acids, as can be used as the first ingredient in the composition, can form an equilibrium in combination with weak acids that can balance additional acids or bases within certain limits. For example, in baking applications, a slightly acidic buffered composition as additive can contribute to dough conditioning, affecting gluten development and enhancing the overall quality of baked goods. Furthermore, the use of a slightly acidic buffered additive in food-items offers enhanced flavor profiles, improved preservation, and effective emulsification and stabilization and thus may enhance the overall quality, taste, and safety of food products.
[0072] While cationic salts have been observed to elevate HMF levels in food, judicious selection of the cationic compound concentrations can be critical, as specifically, higher levels of monovalent cationic compounds haven't been shown to significantly escalate HMF levels. Therefore, in an aspect of the current invention related to the employment of the second component compounds disclosed in this patent, it is possible to concurrently diminish HMF levels while maintaining or even reducing the presence of other foodborne toxins.
[0073] In an especially preferred embodiment, a blend of multiple compounds can be utilized to enhance the functionality or intended efficacy of the second component. The constituents of the second component and their mechanistic impact on food-borne toxin production pathways can further be leveraged to effectively diminish individual toxins or concurrently decrease multiple toxins simultaneously. It is a great achievement of the inventors to have found compositions, which are able to do so while employing comparatively safe and cost-effective salt and acid combinations, as disclosed herein.
[0074] In some embodiments of the invention, composition described in the invention provides a dry and free-flowing products that exhibit excellent stability without the need for additional ingredients such as coating agents, release agents or anticaking agents.
[0075] The reduction in food-borne toxin content refers to the reduction in thermally generated food-borne toxin content by 10 to 100%, preferably by 12 to 95%, more preferably by 14 to 90%, compared to a comparable untreated food-item. An untreated food-item is any item prepared according to common method without the use of special additives and / or ingredients, especially those which modify amino acid composition or content, which aim to reduce the content of food- borne toxins. “Reduces” does not referto the actual chemical process of the composition according to the current invention.
[0076] Advantageously, in preferred embodiment the disclosed products can be effectively utilized in pre-mixes alongside a diverse range of other ingredients. As a result, the final product can be conveniently stored, transported, and seamlessly incorporated into various food products. The dry and free-flowing nature of the product simplifies dosing and ensures precise measurements, allowing for easy integration into the desired food product. This characteristic enhances the versatility and practicality of the composition, providing food manufacturers and intermediary additive suppliers with a practical solution for incorporating the product into their formulations while maintaining product integrity throughout storage, transportation, and usage.
[0077] In one preferred embodiment the salt comprises at least a C2-C6 mono- and / or di- and / or tri-valent carboxylic acid derived anion, preferably substituted with an alkyl, hydroxy, and sulfhydryl group, and / or oxyacid derived anion and at least a metal cation, preferably mono-, di- and / or tri-charged. In another preferred embodiment, the salt comprises or consists of a C2- Cs mono- and / or di- and / or tri-valent carboxylic acid derived anion, preferably substituted with an alkyl, hydroxy, and sulfhydryl group, and / or oxyacid derived anion and at least a metal cation, preferably mono-, di- and / or tri-charged.
[0078] In one alternative embodiment, the first component consists of a cation chosen from sodium, potassium, calcium, or ferric salt of a C2-C6monocarboxylic, dicarboxylic, or tricarboxylic acid preferably substituted with an alkyl, hydroxy, and sulfhydryl group or a mono-, di- or trivalent oxy acid salt.
[0079] The constituents of the first component and their mechanistic impact on food-borne toxin production pathways can be leveraged to effectively diminish individual toxins or concurrently decrease multiple toxins simultaneously. Multivalent cationic C2-C6 monocarboxylic, dicarboxylic, or tricarboxylic acid anions as well as multivalent cationic oxy acid anions can influence the kinetics of Maillard pathways, which have been demonstrated to consistently decrease acrylamide across a range of food products.
[0080] In some preferred embodiments monovalent oxy acid anions, particularly sodium sulfite, and divalent oxy acid anions such as calcium sulfate, have correlated strongly with reductions in furan formation in food. While cationic salts have been observed to elevate HMF levels in food, judicious selection of the cationic compound concentrations can be critical, as specifically, higher levels of monovalent cationic compounds haven't been shown to significantly escalate HMF levels.
[0081] Therefore, it is a great achievement of the inventors to have found compositions in which through careful employment of a combination of the first and second component disclosed in this patent, it is possible to concurrently diminish HMF levels while maintaining or even reducing the presence of other foodborne toxins.
[0082] More preferably the first component is selected from the sodium, potassium, calcium, or ferric salt of acetic acid, propanoic acid, lactic acid, citric acid, malic acid, and tartaric acid or from sodium, potassium, calcium or ferric phosphates, sodium, potassium, calcium, or ferric sulphate and sodium, potassium, or calcium sulfite. A blend of multiple compounds can be utilized to enhance the functionality or intended efficacy of the first component.
[0083] In the spirit of the current invention, amino acids are not regarded as C2-C6mono- and / or di- and / or tri-valent carboxylic acids and / or oxy acids being part of the first component, since the addition of amino acid salts, which are generally basic, would lower the acidity in solution (increase in pH value) of the composition.
[0084] High pH values are detrimental to the reduction of thermally formed food-borne toxins. Any composition with a pH value (10 wt% solution of the composition in water) between 0-7, more preferably between 1 and 6 is considered acidic in the spirit of the current invention. The selection of counter cations of the first component of the invention in food additives is essential. Careful selection of biocompatible and abundant cations offers several technical advantages. First, they result in a lower health risk because they are generally recognized as safe (GRAS). Second, these cations exhibit lower toxicity, which contributes to a safer consumption experience. In addition, their efficient metabolism and elimination from the body result in minimal residue formation. Their better digestibility contributes to easier digestion and improved nutrient absorption.
[0085] In a particularly preferred embodiment, the salt comprises at least an anion selected from the group consisting of C2-C6mono-, di-, tricarboxylates, phosphates, sulfates, sulfites and at least a metal cation selected from the group consisting of sodium (Na+), potassium (K+), calcium (Ca2+) ferric iron (Fe3+), or a mixture thereof.
[0086] In an especially preferred embodiment, high valent cations, such as Ca2+or Fe3+, are preferred. These highly valent ions have been shown to be particularly useful in suppressing certain reaction pathways, with an outstanding achievement of the inventors being that in embodiments in which these ions are combined with certain anions of the first component and acids of the second component, at least two of the three toxins acrylamide, furan, and HMF are reduced simultaneously, which has not been possible previously because highly valent ions can promote the formation of HMF, for example.
[0087] In a most preferred embodiment, the salt comprises at least an C2-Cs mono- and / or di- and / or tri-valent carboxylic acid derived anion selected from the group consisting of acetate, propanoate, lactate, citrate, malate and tartrate and a metal cation selected from the group consisting of sodium (Na+), potassium (K+), calcium (Ca2+) ferric iron (Fe3+) or a mixture thereof. In an alternative most preferred embodiment of the composition according to the current invention the C2-C6mono- and / or di- and / or tri-valent carboxylic acid derived anion, which correspond to C2-Cs mono-, di-, tricarboxylates, is selected from the group consisting of acetate, propanoate, lactate, citrate, malate and tartrate. This has the benefit that the aforementioned acids and its salts are food supplements with E Number in compliance with the EFSA and are exceptionally cost effective. This leads to an especially high economic advantage for compositions comprising acetic acid, propanoic acid, lactic acid, citric acid, malic acid and tartaric acid or a mixture thereof.
[0088] Preferably, the second component of the composition comprises a organic carboxylic acid, preferably a C2-Cs mono- and / or di- and / or tri-valent carboxylic acid preferably substituted with an alkyl, amino, hydroxy, and sulfhydryl group. In particular, the organic C2-C6carboxylic acid, preferably the C2-C6mono- and / or di- and / or tri-valent carboxylic acid, is substituted with a substituent group, wherein the substituent group is selected from the group consisting of alkyl, amino, hydroxy, and sulfhydryl group. It has been observed that the addition of C2-C6monocarboxylic, dicarboxylic, or tricarboxylic acids, especially substituted with an alkyl and hydroxy group, effectively reduces the pH of food, leading to a substantial decrease in the formation of acrylamide and furan. This has the technical advantage of leading to a synergistic effect in conjunction with the first component in reducing the content of thermally formed food-borne toxins.
[0089] In some examples, lowering the pH value has shown to increase the levels of HMF. Therefore, careful selection of the carboxylic acids is required to avoid promoting HMF formation. In a particularly preferred embodiment of the invention, it was found that the combination of the first and second components results in a buffered system that can inhibit low pH (strongly acidic conditions) and thus reduce HMF formation.
[0090] In some embodiments, the second component may include naturally occurring acids, such as natural carboxylic acids, fruit acids or amino acids. This has the advantage that the second component of the composition can be derived from natural sources, thus enabling compositions that are organic, which is a highly desirable consumer criterion. In addition, the second component is more biocompatible, environmentally friendly and less toxic.
[0091] In a more preferred embodiment the organic carboxylic acid, preferably a C2-Cs mono- and / or di- and / or tri-valent carboxylic acid, is selected from the group consisting of acetic acid, propanoic acid, lactic acid, citric acid, malic acid, tartaric acid, glycine, cysteine, leucine, and glutamic acid ora mixture thereof. These acids have been shown to be effective in reducing food-borne toxins. These naturally occurring acids are recognized food additives and / or generally safe for consumption (see Table 2) and are therefore consumer friendly and can be used and sold in most markets, resulting in great economic potential.
[0092] In a preferred aspect of the invention related to amino acids, the addition of glycine leucine and / or glutamic acid has shown to be able to reduce the levels of HMF in food-items. In a preferred embodiment, a combination of these amino acids with a first component according to the present invention may be used to reduce simultaneously the content of acrylamide, HMF and furan. This is unprecedented in the state of the art and is a great improvement, allowing to reduce health hazards of these substances associated with increased cancer risk, genotoxicity and oxidative stress. Since decreasing the pH value may increase the level of HMF, addition of these acids as a second component counteracts this effect thus leading to a broad response of reducing HMF without increasing the other toxins.
[0093] Some economically viable and readily available options for reducing the pH of food products include acetic acid, propanoic acid, lactic acid, citric acid, malic acid, and tartaric acid. These acids are generally considered safe for consumption (see Table 2), ensuring compliance with legal food safety standards, which simplifies labeling and increases consumer confidence. Standardized use of recognized numbers also facilitates international trade by making it easier to demonstrate compliance with specific additive regulations in different markets. Furthermore, these acids are cost effective and easily available, leading to a great economic potential of the composition, especially in comparison with existing alternatives.
[0094] In a preferred embodiment, the composition relates to the reduction of food-borne toxins, alternatively referred to as foodtoxins or food toxins, preferably thermally formed food-borne toxins, particularly preferably the food-borne toxins acrylamide, furan and hydroxymethylfurfural. These substances are formed particularly when foods are heated and represent a major contributor to the toxicity and health risks associated with these foods. Acrylamide, formed when starchy foods are cooked at high temperatures, is a probable human carcinogen associated with an increased risk of cancer, particularly in the kidneys and uterus. Furan, a volatile compound formed when foods are processed at high temperatures, is a possible carcinogen and may increase the risk of liver and gastrointestinal cancers. Hydroxymethylfurfural (HMF), which is formed in certain sugary foods when heated, may have adverse health effects related to genotoxicity and oxidative stress.
[0095] Therefore, reducing acrylamide, furan, and HMF in foods lowers cancer risk, increases food safety, and helps meet regulatory requirements. Lower levels of these compounds lead to improved food quality and longer shelf life. Consumer confidence is boosted by efforts to minimize harmful substances in food, so consumers can make healthier choices.
[0096] Preferably, the composition can reduce the content of preferably at least one, more preferably at least two of the food- borne toxins selected from acrylamide, furan and hydroxymethylfurfural, while the formation of the other food-borne toxins is preferably simultaneously not promoted.
[0097] This is possible since it has been demonstrated that the addition of C2-C6 monocarboxylic or dicarboxylic acids containing amino and sulfhydryl groups, such as glycine or cysteine, has shown the ability to simultaneously lower HMF and acrylamide levels. Especially acids with specific functional groups can offer a promising approach to mitigate the formation of undesirable compounds in food.
[0098] It is therefore a difficult task to find a combination of components that suppress both the formation of acrylamide by a Maillard reaction and the formation of furan and HMF. For example, the literature showed that highly valent metal cations suppress the Maillard reaction while simultaneously increasing the formation of HMF. It is therefore an outstanding achievement of the inventors to have found compositions in which synergistic effects lead to a reduction of all three food- borne toxins mentioned above. In particular, the careful selection of the components play an important role. In some embodiments of the current invention, due to the unique combination of high valent cations and controlled acidic conditions, a number of different food-borne toxins may be reduced simultaneously. A deliberate and well-considered selection of the first and second components can synergistically facilitate the reduction of one or multiple food-borne toxins, even in cases where they exhibit antagonistic behavior. By simultaneously targeting the formation of food-borne toxins through multiple reaction pathways, not only can an effective reduction be achieved, but also a consistent and robust reduction with minimal variation in results.
[0099] Thus, it is an outstanding achievement of the inventors to have found combinations of salt and acid that simultaneously reduce the levels of various food-borne toxins produced during thermal treatment of foods via different reaction pathways, and even to have achieved particularly preferred embodiments in which the combination exhibited unprecedented synergistic effects. These compositions reduce the individual food-borne toxins in a greater amount than the individual components, resulting in a more effective reduction of the overall toxicity of the food, which is very beneficial for consumer health.
[0100] In an especially preferred embodiment of the current invention, the inventors have found a combination of calcium citrate as an embodiment of the disclosed first component and acetic acid as an embodiment of the disclosed second component demonstrates synergistic effects, effectively reducing acrylamide in bakery products by 80 % (Example 7 and Figure 3).
[0101] Further, in an aspect of the invention related to a mixture of potassium acetate and calcium sulfite as embodiments of the disclosed first component in combination with citric acid as an embodiment of the disclosed second component reduces acrylamide by 43% (Example 2 and Figure 1 ) and furan by 26% (Example 3 and Figure 1 ) in dark roasted coffee. Similarly, the beforementioned mixture as an embodiment of the composition disclosed in this patent reduces acrylamide by 14% (Example 4 and Figure 1 ) and furan by 63% (Example 5 and Figure 1 ) in medium roasted coffee. These findings provide compelling evidence that the approach is not only effective in reducing individual food-borne toxins but also capable of simultaneously eliminating multiple food-borne toxins, significantly enhancing food safety overall and enabling compliance to regulatory requirements, as binding thresholds can be met.
[0102] The selection of compounds within the components, the optimal ratios between different compounds within the components, and the ratios of the components to each other depend on various factors, including:
[0103] 1. The physiochemical characteristics of the individual compounds (pKa, solubility, thermal stability, functional groups, etc.).
[0104] 2. The specific food product to which the components are intended to be added.
[0105] 3. The way of addition to the final food product (topical addition, incorporation, soaking, etc.).
[0106] 4. The physiochemical condition and recipe of the food product.
[0107] 5. The processing conditions involved in the production of the food product.
[0108] 6. The regulatory requirements concerning the compounds used in the food product.
[0109] 7. The specific type or types of food-borne toxins that need to be reduced.
[0110] 8. The cost considerations associated with the individual compounds.
[0111] For instance, it has been shown, that a combination out of calcium acetate as an embodiment of the disclosed first component and acetic acid as an embodiment of the disclosed second component can effectively reduce acrylamide in bakery products. The optimal dosage range for this combination is found to be 0.7 to 1 .4 bakers-%, where higher dosages lead to greater reductions in acrylamide content (Example 6 and Figure 2). Similarly, a comparable dosing level of 0.7 to 1 .4 bakers-% can be applied to achieve effective results regarding the reduction of acrylamide in other types of bakery products (Example 7 and Figure 3).
[0112] In a preferred embodiment of the present invention, the composition is applied as a solid component within an ingredient mixture for the thermally treated food-item prior to thermal treatment. The composition is applied in a range of 0.1 to 5.0 baker's percent (%), preferably in a range of 0.2 to 3.0 baker's percent, and most preferably between 0.7 to 1 .4 baker's percent. This ensures that the composition is applied in the spirit of the current invention and the effective reduction of the food-item without influencing the sensory perception of the product.
[0113] In another preferred embodiment of the present invention, the composition is applied as a liquid composition, preferably an aqueous liquid composition, wherein the composition comprises a mass fraction ranging from 5 to 80 weight percent (wt% or w.w.) of the total liquid composition. The untreated food-item is soaked in the liquid composition at a mass ratio of 0.1 to 5.0 (untreated food-item / liquid composition), preferably at a mass ratio of 0.5 to 3.0 (untreated food-item / liquid composition), for a duration ranging from 0.5 to 24 hours. This ensures that the composition is applied in the spirit of the current invention and the effective reduction of the food-item without influencing the sensory perception of the product.
[0114] In this context, "bakers-%" refers to a dosage expressed as a percentage relative to the weight of flour used in the bakery product. Alternatively, it refers to the percentage relative to the weight of the main (most heavy fraction) solid ingredient of a food-tiem.
[0115] In some aspects of the current invention the composition can reduce food-borne toxins, especially acrylamide, furan and hydroxymethylfurfural, preferably by 10 to 100%, more preferably between 12 and 95%, most preferably between 14 and 90% in comparison with the untreated food-items. This solves many of the associated health risks and minimizes consumer exposition, therefore leading to a healthier food-item.
[0116] In a preferred embodiment, the mass fraction of the second component is preferably between 5 and 40%, more preferably between 10 and 35% of the total weight of the composition. In some preferred embodiments, wherein the composition consists of the first and the second component, the mass fraction of the second component is between 5 and 40%, more preferably between 10 and 35% of the total weight of the added masses of the first and second component, and the mass fraction of the first component is between 95 and 60%, preferably between 90 and 65% of the total weight of the composition. This ensures, that a dry, free flowing composition may be archived, even if a liquid C2-C6mono- and / or di- and / or tri-valent carboxylic acid, such as glacial acetic acid, is used, as it is known to the person skilled in the art that salts can be loaded with acids to a certain degree.
[0117] In such preferred embodiments, the inventive composition is related to a series of C2-Cs mono- and / or di- and / or tri-valent carboxylic acids (second component) loaded on salts (first component), which possess controlled acidity and appear in powder form, containing C2-Cs mono- and / or di- and / or tri-valent carboxylic acids, preferably liquid C2-Cs mono- and / or di- and / or tri-valent carboxylic acids. Such compositions are inclusion compounds, wherein the first component, the salt, acts as a carrier, and has the capacity to entrap the second component, the acid. The inclusion of reactive components such a liquid C2-Cs mono- and / or di- and / or tri-valent carboxylic acids has essential benefits as the loaded components, preferably the loaded C2-Cs mono- and / or di- and / or tri-valent carboxylic acids are physiosorbed, which is an interaction without covalent bonding, in the matrix / cavity of the carrier material, whence their reactivity is mediated in the inclusion. The mediated reactivity of the carrier loaded reactants facilitates a control of their acidity, which is essential for the industrial exploitation of reaction pathways. Amongst other, the mediated reactivity of an inclusion compound beneficially facilitates security / stability for storage or during transport in food-treatment industry.
[0118] As used herein, the term dry, free flowing composition, also referred to as powder, refers to a particulate material which is in a macroscopic solid or semisolid state when placed in an open container at atmospheric pressure and room temperature (r.t. , 23°C), and remains in that state over exposed durations, such as 0.1 to 10 years, more preferably between 1 and 72 months.
[0119] In a particularly preferred embodiment of the dry, free-flowing composition, the water content of the composition is between 0.0 and 15%, more preferably between 0.0 and 10%, most preferably between 0.0 and 7.5%. This ensures the free-flowing properties of the composition and long-term storage conditions. The water content may be determined with a Karl Fischer titration method, ensuring precise measurement of the moisture content in the composition. This low water content not only preserves the free-flowing nature and enhances storage stability but also minimizes the risk of unwanted chemical reactions or microbial growth, thereby maintaining the efficacy and safety of the composition over extended periods.
[0120] In a more preferred embodiment regarding an acidic composition, the mass ratio of the second component to the first component is in the range of between 1 :19 and 2:3, more preferably between 1 :9 and 7:13. The acid component plays an important role in reducing many reaction pathways leading to food-borne toxins, as described herein. The inventors have determined that in addition to the selection of substances for the first and second compounds, a carefully balanced composition of the first and second compositions is also required. This allows for the high reduction and multitasking capability of the composition, which can preferably target a number of different toxins simultaneously.
[0121] In a preferred embodiment of the current invention all the components of the composition, especially preferably the first and second component, are approved food additives and / or GRAS substances, more preferably food additives with an E number as approved by the European Food Safety Authority (EFSA) and / or food additives with FEMA number by the Food and Drug Administration (FDA). This has the technical effect that a composition containing components with assigned E numbers or FEMA numbers ensures regulatory compliance with food safety standards, therefore simplifying labeling and enhancing consumer confidence. The standardized use of recognized numbers also facilitates international trade, making it easier to demonstrate compliance with specific additive regulations in different markets.
[0122] Further, while these compounds have received regulatory approval for use in food across major markets, including the European Union and the United States, many of these compounds are even permitted according to organic regulations in these markets, further enhancing their suitability for organic food production. This combination of availability, costeffectiveness, non-GMO status, and regulatory compliance makes the compounds highly advantageous for use in the disclosed composition, providing manufacturers and producers with a reliable and compliant solution for achieving food safety and quality goals.
[0123] In an especially preferred embodiment, the composition is chosen from the first component chosen from Table 1 and the second component chosen from Table 2 or mixtures thereof. Each combination is a new embodiment of the current invention and an aspect thereof.

[0165] Furthermore, a liquid composition for treatment of non-powdered food-items, preferably such as coffee, potato products, nuts, or legumes comprising a composition according to the current invention, wherein the liquid composition comprises the composition in a liquid in a range of 5 to 80 wt%, more preferably in a range of 10 to 60 wt% of the total weight of the liquid composition.
[0166] In certain applications like coffee, potato products, nuts, or legumes, where topical addition or incorporation of additives is not feasible due to the nature or desired characteristics of the final product, soaking the food product in an additive solution becomes necessary. Since the absorption rate of the solution is significantly influenced by factors such as the nature of the food, its penetrability, and environmental conditions like pH, temperature, and the type of solvent used, only a limited amount of the solute can effectively permeate the final food product. As a result, in a preferred embodiment a higher dosage is necessary when compared to a scenario involving topical addition or incorporation.
[0167] In one especially preferred embodiment, a mixture of potassium acetate and calcium sulfite as embodiments of the disclosed first component in combination with citric acid as an embodiment of the disclosed second component (Example 2 and Example 3) was formulated in a 15% w.w. solution with water to facilitate the absorption of the solute by green coffee beans prior to thermal processing, enabling the disclosed product of the invention to effectively showcase its ability to reduce food-borne toxins. The solubility of the individual compounds within the additive mixture holds significant importance in this approach.
[0168] Since there may be remaining unabsorbed solute in the solution after the soaking process, it becomes possible to reuse the solution for subsequent soaking batches.
