Description

[Technical field]

[0001] The present invention relates generally to a method for producing a flavour modifying ingredient using pea proteins, and to the flavour modifying ingredient produced by said method. The invention further relates to flavour compositions and food products comprising said flavour modifying ingredient, and to the use of said flavour modifying ingredient in food products, for example to improve the texture, mask off-notes and / or improve the sweetness of the food product. [Background technology]

[0002] background In the food industry, there is a need to provide raw materials that can modify the flavor of various foods, for example to improve mouthfeel, mask off-notes, and / or improve sweetness.In particular, there is a need to provide natural flavor modifying ingredients to provide clean label foods.Therefore, the present invention provides novel flavor modifying ingredients and methods for producing said flavor modifying ingredients.

[0003] High-intensity sweeteners (HIS) have a sweetness that can be hundreds of times that of low-intensity sweeteners (LIS), such as sucrose. Thus, HIS' can replace large amounts of LIS' in a composition, thereby significantly reducing its caloric value. However, these substances generally have the drawback that they may impart undesirable off-tastes to foods, typically bitter, metallic or licorice, or undesirable lingering sweetness. Effectively modifying the flavor profile of HIS-containing foods is important for consumer acceptance.

[0004] Surprisingly, it has now been found that by subjecting pea protein to the method described herein, a natural healthy ingredient with flavor-modifying effects in food products can be obtained. It has been found that the flavor-modifying ingredient produced by the method described herein can modulate the sweetness profile of HIS' by providing a smoother, more sugar-like sweetness and texture. This ingredient has also been found to modulate the sweetness profile of stevia to be smoother / syrupy when evaluated in a sugar / stevia hybrid base with and without top notes. It has also been found to mask / modify some of the negative attributes of high intensity sweeteners in various hybrid systems used in carbonated and non-carbonated soft drinks. These findings enable the use of HIS' to create healthy, clean-label foods and beverages with improved, cleaner taste and texture. Summary of the Invention

[0039] Pea Protein The term pea(s) as used herein refers to the round seed of the legume plant (Pisum sativum and its cultivars) having a long green pod containing edible seeds. The term pea or pea as used herein encompasses other seeds of the legume family, such as chickpea. Alternatively, pea sprouts may be used instead of pea seeds.

[0040] Pea protein for use in the methods described herein may be in any suitable form, such as in the form of pea seeds or sprouts (including whole or crushed seeds and whole or cut sprouts), or protein isolated from peas, or any natural material containing pea-derived protein and optionally additional ingredients.

[0055] For enzymatic hydrolysis, enzymes or enzyme preparations containing two or more enzymes and having both proteinase and peptidase activity may be used at a temperature appropriate for one or more of the enzymes. The appropriate temperature is selected according to the temperature requirements of the enzyme, for example, Umamizyme™ will tolerate temperatures from about 40°C to about 60°C, with an optimum of about 55°C. A useful enzyme is a protease enzyme preparation, such as Umamizyme (Amano, Elgin, Illinois.) Protease preparations contain two types of enzymes; proteinases, which hydrolyze proteins to form small peptides, and peptidases, which release amino acids from the termini of proteins and peptides. Umamizyme™ is derived from Aspergillus oryzae and is rich in endopeptidase and exopeptidase activity.

[0056] In a particular embodiment, Umamizyme-K is used, which is a food-grade proteolytic enzyme preparation developed for amino acid-rich protein hydrolysates produced by Aspergillus oryzae fermentation under current Good Manufacturing Practices. Umamizyme-K has high peptidase activity in contrast to other fungal proteinase preparations. Umamizyme-K also has high proteinase activity, and the proteolytic coupling system is capable of hydrolyzing a variety of proteins at high levels.

[0057] Other enzymes include Protana Prime, Protana UBoost and Alcalase 2.4 L (all from Novozymes A / S, headquartered in Bagsvard, Denmark). In certain embodiments, the pea protein may be hydrolyzed with Protana Prime, for example, at about 3-4% (enzyme to protein ratio) of protein. In certain embodiments, the pea protein may be hydrolyzed with Protana UBoost and / or Alcalase, for example, at about 1-2% (enzyme to protein ratio) of protein.

[0058] The amount of enzyme is selected to ensure sufficient strength and depends on the activity of the enzyme, the amount of substrate, and the conditions it is used in. The required amount of enzyme can be determined by testing different amounts and testing the effect of the resulting products in sensory evaluations as described herein.

[0059] The enzyme:substrate ratio may, for example, be in the range of about 0.05:20 to about 3:20, for example about 0.5:20 to about 3:20, for example about 1:20. The enzyme may, for example, be used in an amount ranging from about 0.1% to about 20% by weight, based on the total weight of the pea protein. For example, the enzyme may be used in an amount ranging from about 0.5% to about 15% by weight, or from about 1% to about 10% by weight, or from about 0.5% to about 5% by weight, or from about 0.5% to about 1.5% by weight, or from about 1% to about 1.5% by weight, based on the total weight of the pea protein.

[0094] Fermentation may use, for example, the lactic acid bacteria Lactobacillus delbrueckii subsp. bulgaricus, Streptococcus thermophilus, Lactobacillus acidophilus, and Bifidobacterium ssp (ABY 421 from Vivolac Cultures Corporation of Indiana, USA).

[0095] Fermentation may use fungi of the genus Aspergillus, such as, for example, Aspergillus oryzae (also known as koji) and Aspergillus saitoi. In a particular embodiment, the Aspergillus fungus is Aspergillus oryzae.

[0096] In a particular embodiment, the fermentation uses two or more lactic acid bacteria such as Lactobacillus paracasei, Lactobacillus rhamnosus and / or Bifidobacterium, preferably Bifidobacterium animalis lactis, such as, for example, Bifidobacterium animalis lactis, also known as BB-12® from Chr. Hansen, or Bifidobacterium animalis lactis, also known as Probiotic BifidoBHN019 or DR10 or B019.

[0097] In a particular embodiment, the fermentation uses three or more lactic acid bacteria such as Lactobacillus paracasei, Lactobacillus rhamnosus and Bifidobacterium, preferably Bifidobacterium animalis lactis, such as, for example, Bifidobacterium animalis lactis, also known as BB-12® from Chr. Hansen, or Bifidobacterium animalis lactis, also known as Probiotic BifidoBHN019 or DR10 or B019.

[0098] In a particular embodiment, the fermentation uses a combination of the following microbial strains: Lactobacillus delbrueckii subsp. bulgaricus, Streptococcus thermophilus, Lactobacillus acidophilus, and Bifidobacterium ssp.

[0099] Suitable microbial cultures may include the ABY series, such as ABY 424 ND and ABY 421 ND, available from Vivolac Cultures Corporation of Indiana, USA.

[0100] The microbial culture designated ABY 421 ND has the following microbial strains: Lactobacillus delbrueckii subsp. bulgaricus, Streptococcus thermophilus, Lactobacillus acidophilus, and Bifidobacterium ssp. The microbial culture designated ABY 424 ND has the following microbial strains: Lactobacillus delbrueckii subsp. bulgaricus, Streptococcus thermophilus, Lactobacillus acidophilus, and Bifidobacterium ssp.

[0101] ABY 421 ND and ABY 424 ND were formulated using strains of the same genus and species, which have several strains (bacteria) that are classified according to their characteristics, but have differences in their plasmid profiles that determine some of their functional characteristics, such as viscosity production and ability to ferment lactose, phage sensitivity / resistance, etc.

[0102] A blend of two microbial cultures may provide different fermentation rates depending on the ratio of the strains inoculated.

[0103] In certain embodiments, the fermentation uses 100% ABY 421 ND, in other embodiments, the fermentation uses 100% and ABY 424 ND.

[0104] In a particular embodiment, the fermentation uses a combination of ABY 421 ND and ABY 424 ND in a ratio of about 50 / 50. In a particular embodiment, the fermentation uses a combination of ABY 421 ND and ABY 424 ND in a ratio of about 70 / 30, respectively.

[0105] In a particular embodiment, the fermentation uses a combination of ABY 421 ND and ABY 424 ND in a ratio of about 30 / 70, respectively.

[0106] The fermentation may use an overnight culture of the microorganism(s) or the pea protein hydrolysate (or obtained from the enzymatic hydrolysis step) may be directly inoculated with a microbial clone and the fermentation carried out for a slightly longer time accordingly.

[0107] An overnight culture (sometimes called a seed fermentation) may be prepared by methods well known in the art, which may be grown overnight, for example 12 hours, at a temperature suitable for the microorganism. Approximately 37°C is a suitable temperature for many microorganisms, including Lactobacillus paracasei, Lactobacillus casei, Lactobacillus rhamnosus, Lactobacillus bulgaricus, Lactobacillus delbrueckii subsp. bulgaricus, Lactobacillus acidophilus, Lactobacillus plantarum, Lactiplantibacillus plantarum, Lactobacillus brevis, Lactobacillus helveticus, Bifidobacterium, e.g. Bifidobacterium animalis lactis, also known as BB-12® from Chr. Hansen, or Bifidobacterium animalis lactis, also known as Probiotic BifidoBHN019 or DR10 or B019, Streptococcus thermophilus and / or Aspergillus oryzae. Any suitable medium may be used, for example MRS broth (Difco, USA).

[0108] The microorganism may be administered, for example, on a carrier. For example, the microorganism (e.g., Aspergillus oryzae) may be coated on rice grains. For example, the microorganism(s) may be grown on rice grains and provided by a supplier in this form (e.g., available from Rhapsody Natural Foods, Cabot VT 05647). This may, for example, induce the production of certain endogenous enzymes and / or pathways, thereby providing the microorganism with desirable characteristics.

[0109] The amount of microorganism is selected to ensure sufficient activity and depends on the activity of the microorganism, the amount of substrate, and the conditions it is used in. The required amount of microorganism can be determined by testing different amounts and testing the effect of the resulting products in sensory evaluations as described herein.

[0110] The amount of microorganism may, for example, range from about 0.1% to about 1% based on the total weight of the pea protein. For example, the amount of microorganism used may range from about 0.1% to about 0.5% or from about 0.3% to about 0.7% based on the total weight of the pea protein.

[0111] Fermentation is carried out under conditions suitable for all microorganisms involved. As will be apparent to one skilled in the art, temperature and pH should be within suitable ranges for fermentation to occur to the desired extent. Incubation length varies accordingly, with shorter incubations being required the closer the conditions are to optimal conditions. Necessary nutrients may be present if necessary or beneficial for the selected microorganism. Fermentation may be improved by agitating the incubated mixture, for example by stirring (e.g., at 50-500 rpm or 100-200 rpm). Some microorganisms, such as lactic acid bacteria, may grow faster under anaerobic conditions, so minimizing agitation may be preferred. In certain embodiments, aerotolerance may be manganese-dependent.

[0112] Fermentation may be carried out, for example, at a temperature below the temperature at which microorganisms are killed and / or reduced in number. The temperature may be selected, for example, to provide a desired reaction rate. Fermentation may be carried out, for example, at a temperature in the range of about 20°C to about 45°C. For example, fermentation may be carried out at a temperature in the range of about 25°C to about 40°C, or about 30°C to about 40°C, or about 34°C to about 40°C, or about 30°C to about 37°C, or about 30°C to about 35°C.

[0113] Useful temperature ranges for Lactobacilli, particularly Lactobacillus plantarum Lactiplantibacillus plantarum, include, for example, about 20°C to about 40°C, or about 30°C to about 40°C, or about 35°C to about 40°C, with an optimum temperature of about 36°C to about 38°C.

[0114] Useful temperature ranges for Bifidobacteria or lactic acid bacteria, particularly L. delbrueckii ssp. bulgaricus, Streptococcus thermophilus and / or Lactobacillus acidophilus, include, for example, about 20°C to about 40°C, or about 30°C to about 40°C, or about 35°C to about 40°C, with optimal temperatures being about 36°C to about 38°C, or about 30°C to about 35°C, or about 30°C to about 37°C.

[0115] Fermentation may be carried out, for example, at a pH below the temperature at which the microorganism denatures. The pH is selected, for example, to provide a desired reaction rate. Fermentation may be carried out, for example, at a pH in the range of about 5 to about 8, such as about 5 to about 7 or about 6 to about 8 or about 6.5 to about 7.5.

[0116] The fermentation may be carried out for a period of time until the desired product is formed, for example, until the fermentation medium reaches a pH of about 5.5 or less, such as a pH of about 4.5 to about 5.5.

[0117] Fermentation may occur for a period ranging from about 1 day to about 10 days, for example. Fermentation may occur for a period ranging from about 2 days to about 9 days, or from about 3 days to about 8 days, or from about 4 days to about 7 days.

[0118] In certain embodiments, the fermentation may occur for a period ranging from about 1 day to about 8 days, or from about 2 days to about 6 days, or from about 2 days to about 5 days, or from about 2 days to about 4 days, or from about 1 to about 2 days.

[0119] Further processing steps The products of the enzymatic hydrolysis and fermentation may, for example, be used directly as a flavour modifying ingredient, however, the process may, for example, include one or more additional steps.

[0120] The pea protein subjected to the enzymatic hydrolysis and fermentation described herein may, for example, be an aqueous slurry of pea protein. The pea protein subjected to the enzymatic hydrolysis and fermentation described herein may also, for example, be a pea protein base. In certain embodiments, the pea protein is used as a substrate in combination with other ingredients, such as solvents, binders, diluents, disintegrants, lubricants, colorants, preservatives, antioxidants, emulsifiers, stabilizers, anticaking agents, gums, starches, dextrins, vitamins, minerals, functional ingredients, etc. Thus, in certain embodiments, the method may include combining the pea protein with water or other ingredients prior to the enzymatic hydrolysis and fermentation. The aqueous slurry of pea protein or the pea protein base may, for example, comprise at least about 5% by weight of pea protein, such as at least about 10% by weight of pea protein, such as at least about 15% by weight of pea protein. The aqueous slurry of pea protein or the pea protein base may, for example, comprise up to about 90% by weight of pea protein, or up to about 50% by weight of pea protein, or up to about 30% by weight of pea protein.

[0121] In a particular embodiment, the aqueous slurry of pea protein or the pea protein base is sterilized prior to forming the pea protein hydrolysate. For example, the aqueous slurry of pea protein or the pea protein base may be sterilized by heating the aqueous slurry of pea protein or the pea protein base to about 120-125°C for about 30 minutes and subsequently cooling the aqueous slurry or the pea protein base to about 50°C.

[0122] In certain embodiments, the pea protein is present in an amount of about 5% to about 60% by weight, based on the total weight of the aqueous slurry or the pea protein base. In certain embodiments, the pea protein is present in an amount of about 5% to about 50% by weight, based on the total weight of the aqueous slurry or the pea protein base. In certain embodiments, the pea protein is present in an amount of about 5% to about 40% by weight, based on the total weight of the aqueous slurry or the pea protein base. In certain embodiments, the pea protein is present in an amount of about 10% to about 30% by weight, based on the total weight of the aqueous slurry or the pea protein base.

[0123] The enzymatic hydrolysis and fermentation should be carried out in a sterile container, therefore the container may be sterilized before adding the pea protein.

[0124] The pea protein (e.g. an aqueous slurry of pea protein or a pea protein base) may, for example, be heated prior to the enzymatic hydrolysis and / or fermentation. For example, the pea protein may be heated to a temperature of about 50° C. or higher, for example to a temperature in the range of 50° C. to about 55° C., or may be heated to a temperature of about 75° C. or higher, for example to a temperature of about 100° C. or higher or about 110° C. or higher, prior to the enzymatic hydrolysis and / or fermentation. For example, the pea protein may be heated to a temperature of about 140° C. or lower, for example to a temperature of about 130° C. or lower, prior to the enzymatic hydrolysis and / or fermentation. For example, the pea protein may be heated to a temperature of about 121° C. prior to the enzymatic hydrolysis and / or fermentation. This may be to inactivate and / or kill any microbial contaminants and / or to hydrate and / or preheat the pea protein (e.g. an aqueous slurry of pea protein or a pea protein base) prior to the enzymatic hydrolysis and / or fermentation. The pea protein is then maintained at a temperature suitable for enzymatic hydrolysis and / or fermentation and / or cooled to a temperature suitable for enzymatic hydrolysis and / or fermentation before the enzyme(s) and / or microorganism(s) are added.

[0125] The enzyme(s) and / or microorganism(s) may be inactivated, for example, before incorporation into a flavor composition or food product. This may be done, for example, by heating to a temperature ranging from about 60° C. to about 121° C., for example about 100° C., for a period of time long enough to inactivate the enzyme(s) and / or microorganism(s). For example, any pasteurization or sterilization method known in the art may be used. For example, the enzyme and / or microorganism may be inactivated by heating to about 70° C., about 90° C. or above about 100° C. for 30 minutes or 45 minutes or 60 minutes. When heating above about 100° C., for example above about 121° C. for about 30 minutes, heating may be done under pressure, for example at about 12 to about 15 psi.

[0126] The products of enzymatic hydrolysis and fermentation (flavor modifying ingredients) may, for example, be filtered or centrifuged to remove large particles. The products of enzymatic hydrolysis and fermentation (flavor modifying ingredients) may, for example, be concentrated by evaporation, including boiling points up to about 100° C. The products of enzymatic hydrolysis and fermentation (flavor modifying ingredients) may, for example, be spray dried using methods known in the art, for example, and carriers such as maltodextrin and / or anti-caking agents.

[0127] Filtration may be performed by any suitable filtration method, such as by passing through felt filter bags in a filter centrifuge, which are well known in the art. The filtered culture (the remaining supernatant containing smaller solids minus the biomass containing the larger undigested proteins) may be concentrated, for example, 2x by evaporation / boiling at 100°C. The solids content of the resulting concentrate may be determined using a moisture analyzer, and may be, for example, spray-dried onto a suitable carrier. Many carriers are known in the art, such as, but not limited to, potato maltodextrin carriers (e.g., a ratio of about 1:1 solids of the 2x concentrate to the carrier may be suitable). Optionally, an anti-caking agent may be added, such agents being well known. A suitable anti-caking agent is, for example, tricalcium phosphate (TPC), and about 0.5% (wt / wt) based on the total weight of the 2x concentrate would be a suitable amount.

[0128] The flavour modifying ingredients may be used, for example, in filtered and / or concentrated form.

[0129] The products of enzymatic hydrolysis and fermentation (flavor modifying components) may be combined with one or more stabilizers, such as, for example, propylene glycol.

[0130] product The flavor modifying ingredient made by the process described herein may be used directly in a flavor composition and / or food composition, or may undergo further processing as described above. For example, the flavor modifying ingredient may be in filtered and / or concentrated and / or paste and / or spray-dried form. The flavor modifying ingredient may be combined with a stabilizer, such as propylene glycol, or may be combined with one or more carriers and / or anticaking agents used in the spray-drying process. The flavor modifying ingredient may be considered to be a natural clean label product, for example, for food labeling and / or food regulatory reasons. By way of example, the flavor modifying ingredient may be considered to be, for example, a Ready to Eat (RTE) or Ready to Drink (RTD) product and a Ready to Eat (RTE) or Ready to Drink (RTD) product.

[0131] The final form of the flavor modifying ingredient may be selected according to methods known in the art and depends on the particular food application.For liquid foods, such as beverages, the flavor modifying ingredient may be used in its liquid form without further processing.For dry applications, such as crackers, spray-dried concentrated flavor modifying ingredients may be used.

[0132] The flavour modifying ingredients may be added directly to the food product or may be provided as part of a flavour composition for flavouring or seasoning the food product.

[0133] The flavor composition contains a flavor modifying ingredient and, optionally, one or more food grade excipients. Excipients suitable for flavor compositions are well known in the art and include, for example, but are not limited to, solvents (including water, alcohol, ethanol, fats and oils, vegetable oils, migliol), binders, diluents, disintegrants, lubricants, flavoring agents, coloring agents, preservatives, antioxidants, emulsifiers, stabilizers, flavor enhancers, sweeteners, anti-caking agents, and the like. Examples of such carriers or diluents for flavors may be found, for example, in “Perfume and Flavor Materials of Natural Origin”, S. Arctander, Ed., Elizabeth, NJ, 1960; in “Perfume and Flavor Chemicals”, S. Arctander, Ed., Vol. I & II, Allured Publishing Corporation, Carol Stream, USA, 1994; in “Flavourings”, E. Ziegler and H. Ziegler (ed.), Wiley-VCH Weinheim, 1998, and “CTFA Cosmetic Ingredient Handbook”, JM Nikitakis (ed.), 1st ed., The Cosmetic, Toiletry and Fragrance Association, Inc., Washington, 1988.

[0134] The flavour composition may contain flavour compounds, flavours from natural sources including botanical sources, and additional flavour ingredients including ingredients produced by fermentation.

[0135] The flavour composition may have any suitable form, for example liquid or solid, wet or dry, or encapsulated, bound to or coated on a carrier / particle, or as a powder.

[0136] In certain embodiments, the flavor composition may, for example, comprise from about 0.001% to about 50% (wt / wt) of the flavor modifier, based on the total weight of the flavor composition. In certain embodiments, the flavor composition comprises from about 0.1% to about 40% (wt / wt) of the flavor modifier, based on the total weight of the flavor composition. In certain embodiments, the flavor composition comprises from about 1% to about 30% (wt / wt) of the flavor modifier, based on the total weight of the flavor composition. In certain embodiments, the flavor composition comprises from about 1% to about 20% (wt / wt) of the flavor modifier, based on the total weight of the flavor composition. In certain embodiments, the flavor composition comprises from about 2% to about 20% (wt / wt) of the flavor modifier, based on the total weight of the flavor composition. In certain embodiments, the flavor composition comprises from about 3% to about 15% (wt / wt) of the flavor modifier, based on the total weight of the flavor composition.

[0155] In certain embodiments, the flavor modifying ingredient is added to a sweetened food product. In certain embodiments, the food product is sweetened with at least one high intensity sweetener and / or at least one low intensity sweetener.

[0156] The one or more sweeteners added to the flavor composition or food product may be natural, artificial, and / or high intensity, and may function to make the product more appealing. Natural high-intensity sweeteners such as stevia or stevia derivatives may be used as a substitute for other sweeteners, such as other natural high-intensity sweeteners, sugars (e.g., liquid sugar, crystallized sugar, honey, agave, sugar cane juice, etc.), and / or artificial sweeteners (e.g., sucralose, aspartame, saccharin, etc.), or in combination with other sweeteners to provide low calories.

[0158] use The flavour modifying ingredients obtained and / or obtainable by the methods described herein may be added to a food product (e.g., as part of a flavour composition) to, for example, modify the flavour or texture of the food product.

[0159] The flavour modifying ingredients obtained and / or obtainable by the methods described herein may be used, for example, to improve the texture of a food product, and / or to mask off-notes in a food product, and / or to improve the sweetness of a food product, and / or to act as a prebiotic in a food product.

[0160] Thus, also provided herein is a method of providing a food product having improved texture and / or reduced off-notes and / or improved sweet taste and / or prebiotic use and / or prebiotic use, comprising mixing with a food product a flavour modifying ingredient obtained and / or obtainable by the method described herein.

[0161] In general terms, "texture" refers to the complexity of sensations experienced in the mouth as influenced by the aroma, taste, and eating quality of food and beverage products. However, from a technical point of view, mouthfeel sensations relate specifically to the physical (e.g., touch, temperature) and / or chemical (e.g., pain) properties perceived in the mouth via the trigeminal nerve. They are therefore the result of oral tactile stimulation, engaging mechanical, pain and temperature receptors located in the oral mucosa, lips, tongue, cheeks, palate and throat.

[0162] Mouthfeel perceptions include, for example, one or more of texture-astringent, burning, cold, stinging, thick, chewy, fatty, oily, slimy, foaming, melting, sandy, chalky, watery, acidic, ringing, metallic, body, body sweet, carbonation, cooling, warming, hot, juicy, dry mouth, numbing, hot, salivating, spongy, sticky, fluffy, cohesive, density, friability, graininess, granular, rubbery, hardness, weight, hygroscopicity, moisture release, texture, texture, roughness, slipperiness, smoothness, uniformity, uniformity of bite, uniformity of wicking, viscosity, fast spreading, full body, salivation and retention.

[0163] As previously mentioned, the perceived texture of a food or beverage can be widely influenced by the presence of aroma and taste attributes in addition to textural characteristics. Thus, numerous other attributes can affect the overall experienced texture of a product, including, for example, one or more of the following tastes or aromas: sweet, salty, umami, sour, bitter, creamy sour, acidic, sour dairy, green onion, roasted onion, and parsley.

[0164] "Improved texture" means that any one or more desirable texture perceptions are enhanced and / or any one or more undesirable texture perceptions are reduced. In particular, one or more of the following perceptions may be enhanced: sweet, smooth, syrupy, sugar-like.

[0165] "Off-note masking" means that the intensity and / or duration of the perception of an undesirable attribute in a food is reduced when a food containing an ingredient with off-note masking is compared to a food that does not contain the added off-note masking ingredient, as analyzed by trained panelists.

[0166] "Sweet taste improvement" means the effect of a flavor modifying ingredient on the sweetness characteristics of a food product that is found to be more preferable as analyzed by trained panelists when a food product containing an ingredient having a sweet taste improving effect is compared to a food product without the added sweet taste improving ingredient.

[0167] Sweet taste improvement may, for example, provide a sweetness profile more similar to that of sucrose (sugar).

[0168] Sweetness characteristics can refer to a flavor profile, which may refer to the intensity of the flavor and sensory attributes of a given compound. Exemplary flavor attributes of sweetness are sweetness intensity, bitterness, black licorice, etc.

[0169] Sweetness profile may refer to a time profile, which refers to the change in sweetness perception over time. All sweeteners exhibit a characteristic appearance time (AT) and disappearance time (ET). Most high intensity sweeteners exhibit an extended ET (retention). In general, the detected sucrose equivalent spikes to a maximum response level and then tapers off over time. The longer the taper, the greater the detected sweetness ringer of the compound.

[0170] Sweet taste improvement may be particularly obtained, for example, when the flavor modifying ingredient is used in a sweetened food product. Sweet taste improvement may be particularly obtained, for example, in a beverage, such as a sweetened beverage.

[0171] In certain embodiments, the flavor modifying ingredient may be used to reduce the lingering sweetness of a food product (e.g., a sweetened food product). In other words, the flavor modifying ingredient may be used to reduce the extinction time (ET) of a food product (e.g., a sweetened food product). This relates to the undesirable persistence of sweetness in the mouth after the food product is first ingested or spat out. Lingering sweetness may refer, for example, to the length of time that sweetness remains after it is first detected, how quickly the intensity of sweetness decreases or disappears after it is first detected, and the intensity of sweetness after it is first detected. The flavor modifying ingredient may, for example, decrease the length of time that sweetness remains after it is first detected, and / or increase the rate at which sweetness decreases after it is first detected, and / or decrease the intensity of sweetness after it is first detected.

[0172] In certain embodiments, the flavour modifying ingredients may be used to reduce the bitter and / or astringent and / or metallic and / or liquorice taste of a food product (eg, a sweet food product).

[0173] In certain embodiments, the flavor modifying ingredient may be used to enhance the sweetness impact of a food product (e.g., a sweet food product). Sweetness impact relates to the length of time it takes for sweetness to be first detected and the intensity at which sweetness is first detected. The flavor modifying ingredient may, for example, decrease the time it takes for sweetness to be first detected and / or increase the intensity at which sweetness is first detected.

[0174] Sweetness intensity and other sweetness attributes described herein may be evaluated by a trained expert taste panel, for example as described in the examples below.

[0175] "Prebiotic" refers to the effect of flavor modifying ingredients to improve the effect of the gut flora, for example by increasing the activity of the gut flora and / or by increasing the population of the gut flora. "Probiotic" refers to live bacteria, for example a microbial strain or blend of strains as described herein, fermented substances, for example pea protein.

[0215] example Example 1 - Preparation of flavour modifying ingredients using pea protein A slurry was prepared with 15% pea protein isolate in water.

[0216] The pea proteins in the slurry were then partially hydrolyzed by Umamizyme (Amano) added at 0.1 to 1% levels at 50°C for approximately 4 h.

[0217] The slurry was then heated to 121° C. for 45 minutes to remove microbial contamination from the starting material and to inactivate the enzymes, and then fermented with cultures BB-12® (Bifidobacterium animalis lactis) or LGG® (Lactobacillus rhamnosus) for approximately 24 hours.

[0218] The initial pH of 6.18 decreased to 5.35 for LGG® and to 4.9 for BB-12®.

[0219] Final heat treatment of the samples was at 121°C for 15 minutes.

[0220] Sensory evaluation was performed by trained expert panelists at 0.15% in a non-dairy yogurt base. Both samples were considered to provide a pleasant flavor and good textural properties.

[0221] Example 2 - Preparation of Flavor-Modifying Ingredients Using Organic Pea Protein Isolate A slurry was prepared with approximately 18% organic pea protein isolate (obtained from Puris, LLC, Wisconsin, USA) in water with the addition of 0.1% NaCl.

[0222] The slurry was sterilized at 121°C for 30 minutes to remove microbial contamination from the starting material and cooled to 50°C.

[0223] The pea proteins in the slurry were then hydrolyzed with Umamizyme (Amano) added at about 0.6% (or 4% enzyme to protein ratio) at 50°C for about 16 hours.

[0224] Glutaminase PG-500 (Amano) was then added at 0.02% (or 0.13% on protein) and the process continued for a further 2 h at 50°C.

[0225] The slurry was then cooled to 37°C, inoculated with Lb plantarum added at approximately 0.3%, and incubated at 37°C with minimal agitation for 6 hours.

[0226] Terminal sterilization of the slurry was at 121°C for 45 minutes.

[0228] Example 3 - Citrus flavoured beverage containing flavour modifying ingredients A citrus-flavored beverage was prepared using a stevia / sugar hybrid base in water containing 3% sucrose, 0.05% citric acid, and 0.008% rebaudioside A.

[0229] A flavor modifying ingredient produced according to the process described in Example 2 was added to a citrus flavored beverage at a concentration of 1 ppm.

[0230] A sensory evaluation of the modified citrus flavored beverage was conducted by sensorily trained expert panelists. The panelists found that the modified citrus flavored beverage provided a pleasant sugar taste and texture. The sensory descriptors / comments used / provided by the panelists were: masking off-notes, adding mouthfeel, and increasing sugar. A sugar-like taste is highly desirable in a sugar reduced / partially replaced carbonated soft drink. The citrus flavored beverage also had a low caloric value due to the sugar blend (stevia / sugar hybrid based) used to prepare the beverage.

[0231] Example 4 - Plant-Based Protein Drinks Containing Flavor-Modifying Ingredients A plant-based protein drink was prepared using 3% sucrose, 3% pea protein and 0.03% gellan gum in water.

[0233] A sensory evaluation of the modified plant-based protein beverages was conducted by sensorily trained expert panelists. The panelists found that the modified plant-based protein beverages provided a pleasant taste and texture. The sensory descriptors / comments used / provided by the panelists were: masking off-notes, adding mouthfeel, and increasing sugar.

[0234] Example 5 - Lemon-lime carbonated soft drink containing flavour modifying ingredients A lemon-lime carbonated soft drink (100 calories) was prepared having the following composition: [Table 1]

[0235] The flavor modifying ingredient produced according to the process described in Example 2 was added to a lemon lime carbonated soft drink at a concentration of 1 ppm.

[0236] A sensory evaluation of the lemon lime carbonated soft drink without the flavor modifying ingredients (control) and the modified lemon lime carbonated soft drink containing the flavor modifying ingredients was performed by sensory trained expert panelists. The panelists found the following: The modified lemon-lime carbonated soft drink had better initial sweet impact, brighter flavor and a thinner body compared to the control. The modified lemon-lime carbonated soft drink had a good sweetness, clean finish and did not impart the unpleasant lingering sweetness present in the control. The modified lemon-lime carbonated soft drink provided a reduced "artificial" sweetness peak that more closely matched the taste of sucrose (sugar) compared to the control. The modified lemon-lime carbonated soft drink had stronger cane notes and was higher in sugar than the control.

[0237] Example 6 - Lemon-lime carbonated soft drink containing flavour modifying ingredients A lemon-lime carbonated soft drink (100 calories) was prepared having the following composition: [Table 2]

[0238] The flavor modifying ingredient produced according to the process described in Example 2 was added to a lemon lime carbonated soft drink at a concentration of 1 ppm.

[0245] Example 9 - Fermentation test Fermentation tests were performed on a non-dairy yogurt base, i.e. a pea protein base, using different microbial cultures. The aim of the test was to determine the correct pH range with a good timeline. The non-dairy base contained, by weight % (g), 75.74% water, 13.30% pea protein isolate (PURIS® P870), 9.00% UHT coconut cream, 1.00% sucrose, 0.50% calcium complex, 0.050% citrus fiber (CITRI-FI 100M40; 200 mesh), and 0.010% pea protein binder. A non-dairy base was prepared according to the following steps: i) adding pea protein isolate and pea protein binder flavor to water at 55-60°C; ii) hydrating the protein with water at 55-60°C at high shear for 30 minutes; iii) mixing all dry ingredients and adding while hydrating the protein; iv) melting and adding coconut fat and continuing mixing for 15 minutes; v) heating the slurry to 62°C; vi) homogenizing at 2500 / 500 psi; vii) heat treating at 95°C for 8 minutes; and viii) cooling to 40°C.

[0246] The two cultures were formulated with the following microbial strains: Lactobacillus delbrueckii subsp. bulgaricus, Streptococcus thermophilus, Lactobacillus acidophilus, and Bifidobacterium ssp. strains were classified according to their characteristics, but with differences in their plasmid profiles that determined some of their functional characteristics such as viscosity production and ability to ferment lactose, as well as phage sensitivity / resistance. Culture 1 (C1-ABY 421 from Vivolac) is very slow to ferment, giving a high viscosity with a very mild almost neutral flavor. Culture 2 (C2-ABY 424 from Vivolac) is a faster acid producer with a high viscosity and slightly stronger acetaldehyde (yogurt flavor).

[0247] Tests carried out Basal Testing - The pH of the basal was tested to be 6.87 at refrigerated temperature. The basal was also plated for the presence of E. coli and standard plate counts.

[0248] The percent solids was determined to be 18.43%.

[0249] Overnight Fermentation Instructions: Ten 150mL samples of non-dairy yogurt based were allocated into sterile jars. Two 150mL samples of Ultra High Temperature (UHT) milk (shelf stable) were allocated into sterile jars. One set of five non-dairy yoghurt base samples and one UHT milk sample was tempered at 40°C and the other set at 42°C. · Samples were inoculated at the rate of 0.4% as given in Table 1, stirred and a small amount of each of UHT milk and non-dairy yoghurt base was added to sterile jars as uninoculated controls. The samples were incubated for 16 hours. At the end of the 16 hours the pH was measured.

[0250] [Table 3]

[0251] Uninoculated controls of both the UHT dairy and non-dairy yoghurt based did not acidify after 16 hours of incubation.

[0252] Daytime fermentation procedure: · Two 150mL samples of non-dairy yogurt base were allocated into sterile jars. ·One 150mL sample of UHT milk was allocated into a sterile jar. The sample was heated to 40°C. · Samples were inoculated at 0.4% with the ratios listed in Table 2 and blended by stirring. As uninoculated controls, small amounts of each of UHT milk and non-dairy yoghurt base in sterile jars were added. The samples were incubated at 40°C for 7.5 hours. pH levels were measured every 5 and 30 minutes for 7 and a half hours or until a pH of 4.4 was reached.

[0253] [Table 4] [Table 5]

[0254] The activity of 50% / 50% C1-C2 in UHT milk reached pH 4.4 within 5 hours, whereas in non-dairy yoghurt base the activity at the same inoculation ratio reached pH 4.66 in 7.5 hours. 100% C2 inoculation into non-dairy yoghurt base reached pH 4.55 in 7.5 hours. Uninoculated controls in both UHT milk and non-dairy yoghurt base did not acidify after 7.5 hours of incubation.

[0255] conclusion The uninoculated control base sample did not experience a drop in pH in any of the fermentations, indicating that there were no acid-producing bacteria present in the base itself. Culture activity was slower when inoculated at the same rate into the non-dairy yogurt base compared to UHT milk. Activity in samples fermented at 42°C was faster than samples fermented at 40°C. 100% C2 activity was faster than 100% C1 activity. Blends of the two cultures gave different fermentation rates depending on the ratio of microbial strains inoculated. Blends with a higher proportion of C2 were faster than blends with less C2 (and more C1). The sample that reached pH 4.4 was the 16-hour fermentation of 100% C2 at both temperatures. The next closest sample to reaching pH 4.4 in 16 hours was the 30% / 70% C1 / C2 fermented at 42°C. Some differences in curd size were observed. C1 produced a smooth curd with small size and good texture.

[0256] [Table 6]

[0257] The first five microbial cultures listed in Table 4 (i.e., 716593, 716594, 720758, 704993 and 716628) were obtained from Chr. Hansen A / S, Horsholm, Denmark.

[0258] The remaining two microbial cultures listed in Table 4 (i.e., ABY 421 ND and ABY 424 ND) were obtained from Vivolac Cultures Corporation of Indiana, USA. The cell surface structures of Bifidobacterium animalis lactis (BB-12®) and Lactobacillus rhamnosus (LGG®) have been found to provide good texture and mouthfeel in flavor applications.

[0259] Example 10 - Further sensory evaluation of strains or strain blends Fermentation continued with strains or strain blends for samples 7, 8, 9 and 11 (detailed in Table 1 in Example 9). Two to three samples of each strain or strain blend were taken at different pH levels and the sensory properties were evaluated to find the optimum solution close to dairy replacement. Pre-acidify the water at 5-6 pH before fermentation and study the sensory properties. Increase sugar and culture to find out how it affects pH and sensory properties.

[0260] Example 11 – Fermentation of chickpea flour A slurry was prepared using 10% chickpea flour (Organic Chickpea Flour obtained from Cambridge Commodities Inc., California, USA or Organic Chickpea Flour obtained from Firebird Artisan Mills, North Dakota, USA) in water. The slurry was sterilized at 121°C for 45 minutes to remove microbial contamination from the starting material and cooled to 37°C. The slurry was then inoculated with LGG® (Lactobacillus rhamnosus) or BB-12® (Bifidobacterium animalis lactis) or YOFLEX® YF-L01 DA (Streptococcus thermophilus) or YOFLEX® YF-L02 DA (Lactobacillus bulgaricus) or L.Casei 431 (Lactobacillus paracasei) added at 0.4% and incubated at 30-37°C for 24 hours with minimal agitation. The final slurry was then heated at 121°C for 15 minutes. The initial pH of about 6 was reduced to below 4 in all cases except when LGG® was used, and the final pH was about 5. Sensory evaluation of the fermented chickpea flour at 0.15% was performed with expert panelists trained in vegan Alfredo sauce and bland non-dairy sauces. The sensory descriptors used by the panelists for the vegan Alfredo sauce were: creamy dairy notes, as well as adding salt, umami, brothy; masking beany-off notes from the base. The sensory descriptors used by the panelists for the bland, dairy-free sauce were creamy, pleasant texture with a cultured / dairy impression. These flavor modifiers can be formed into ready-to-eat and / or ready-to-drink products by modifying the levels of solid starting materials and adjusting the process so that the final inactivation of microorganisms is optional.
