Description

[0001] Flow agents for use in bulk materials and bulk material composition

[0002] This patent application claims priority from German patent application DE 10 2023 208 947.5, the contents of which are incorporated herein by reference.

[0003] The invention relates to a flow aid for use in, particularly hygroscopic, bulk materials, for example in food or animal feed. The invention also relates to a bulk material composition and products containing the same, in particular food, animal feed, and pigment powder. The invention also relates to the use of a powder as a flow aid in, particularly hygroscopic, bulk materials.

[0004] Particularly in the food and feed industries, bulk materials that tend to stick together often have to be handled and processed. Hygroscopic bulk materials, such as salt, sugar, pieces of fruit and / or vegetables and / or powders made from these, tend to absorb water from their surroundings due to their physical properties. This hygroscopic behavior can be described using so-called sorption isotherms, where the increase or decrease in water content as a function of the relative humidity at a certain temperature is determined as a measure of the hygroscopicity of a bulk material. Due to the water absorption, the bulk particles form a sticky surface, which reduces flow properties and can subsequently lead to problems during industrial processing and even production downtime.For example, dried apple pulp, which is used in various particle sizes for fruit tea blends, exhibits pronounced hygroscopicity. Foods containing this material, such as fruit tea blends, can stick together, making it impossible to ensure high filling cycle times and even leading to production downtime. Another example is bulk materials with a fat content and a low dropping point. The fatty components of these bulk materials can melt at ambient temperatures above their respective dropping points, thus causing the bulk material to stick together.

[0005] To improve the flowability of bulk materials, it is well known that flow aids are added. Many flow aids, such as silicon dioxide, are not approved or only approved with restrictions in the food industry. Rice starch is often used as an alternative, but this leaves a discolored film on the bulk material, which is detrimental to the product's aesthetic appearance. Therefore, there is a constant need to improve flow aids for bulk materials, especially hygroscopic ones.

[0006] The object of the present invention is therefore to provide an improved flow aid, in particular for the food and feed industry, in particular to provide a flow aid based on natural ingredients.

[0007] This object is achieved by a flow aid having the features specified in claim 1. This object is further achieved by a bulk material composition according to claim 11, which can be used in particular in foodstuffs, animal feed, or pigment powder. The object is also achieved by the use of a powder according to claim 26. Preferred embodiments are the subject of the dependent claims. The flow aid for use in bulk materials, in particular in foodstuffs or animal feed, comprises a powder made from crushed fruit seeds of berries or soft fruit and / or from crushed fiber-containing plant products. In particular, the flow aid can consist of the powder. The comminution of the fruit seeds and / or fiber-containing plant products can take place in particular by grinding. The inventors have recognized that corresponding powders are excellently suited as flow aids or components thereof.By coating the surface of the bulk material particles with the powder, a microscale layer is created, which facilitates the rolling of the individual bulk material particles against each other and thus enables good flowability. Sticking of the bulk material particles, for example, due to their hygroscopic properties and / or due to the melting of components, especially fatty ones, is prevented. The flow aid can be used particularly advantageously in hygroscopic bulk materials and / or bulk materials with a low dropping point.

[0008] The flow aid is particularly advantageous for use in hygroscopic bulk materials. It has also been shown that corresponding powders exhibit a high water absorption capacity, in particular, they can absorb more water from the environment than previously used flow aids. This reduces, and in particular prevents, water absorption by the particles of the hygroscopic bulk material and the clumping of the particles.

[0009] A particular advantage of the flow agent is that the powder's raw materials—fruit seeds from berries and / or soft fruits or fibrous plant products—occur as side streams, by-products, or waste products in many industrial processes, particularly in the food or feed industries. Often, entire plants or parts of plants must be purchased from suppliers. Unusable components arise as side streams, by-products, or waste products. Surprisingly, it has been found that the latter, when crushed, especially when ground, are suitable as flow agents. This opens up a potential application for these side streams. The flow agent is economical and conserves resources.

[0010] A further advantage of the flow agent is that the powder's raw materials consist of natural ingredients, so that the use of synthetic, purified or highly processed additives is reduced, or even completely avoided.

[0011] A further advantage is that the powder's raw materials can come from a wide range of plants. This counteracts supply bottlenecks and shortages, for example, due to climate change. Depending on the bulk material, raw materials can be selected that are based on plants that are also part of the bulk material in the form of other plant components. This reduces, and in particular prevents, any influence on other properties of the bulk material, such as color and taste.

[0012] The fruit seeds and berries and / or soft fruits, as well as the fiber-containing plant products, are primarily plant components of edible or edible plants. The flow agent is suitable for consumption directly and / or as an infusion. There are no approval issues for use in food, feed, or cosmetic products.

[0013] The flow aid comprises, in particular, a powder of crushed, in particular ground, fruit seeds of berries and / or soft fruit, and can in particular consist of this.

[0014] A berry, as used herein, is a berry in the botanical sense. A berry is a closed fruit arising from a single ovary, in which the entire fruit wall (pericarp) remains juicy or at least fleshy even when ripe. Botanical berries include, among others, bananas, blueberries, citrus fruits, dates, melons, kiwis, papayas, the fruits of many nightshade plants, such as peppers or tomatoes, and avocados.

[0015] For the purposes of the present invention, berry fruit refers to a perennial, particularly edible, fruit species with mostly soft, small, and round fruits. Berry fruit is a collective term for fruit species that share common characteristics, particularly in their fruit properties. Berry fruits are often called berries due to their external shape, even though they are not berries in the botanical sense. Rosaceae are among the main berry species. Berry fruits include, in particular, chokeberry, blackberry, strawberry, currant, blueberry, raspberry, elderberry, mulberry, cloudberry, cranberry, lingonberry, sea buckthorn, gooseberry, tayberry, and grape berry. According to a preferred aspect of the flow agent, the powder comprises crushed, particularly ground, fruit seeds of Rosaceae. The powder preferably consists of these. Fruit seeds of rose plants are particularly suitable starting materials for the flow agent.They often occur as side streams in industrial production, especially in food production. Suitable Rosaceae plants include rose hips, blackberries, raspberries, and / or strawberries.

[0016] According to a preferred aspect of the flow agent, the powder comprises crushed, especially ground, rosehip seeds. The powder preferably consists of crushed, especially ground, rosehip seeds. Powders made from crushed rosehip seeds have proven to be particularly suitable flow agents. They exhibit a particularly high water absorption capacity.

[0017] According to a preferred aspect, the flow agent consists of a powder made from crushed, especially ground, rosehip seeds. The flow agent is particularly well-suited for food applications. The flow agent does not contain any other components that could be potentially problematic, particularly for food applications.

[0018] According to a preferred aspect of the flow aid, the powder comprises comminuted, in particular ground, citrus fruit seeds. The powder can consist of these, in particular. Citrus fruit seeds have proven to be particularly suitable starting materials for the powder of the flow aid, either as an alternative or in addition to rose fruit seeds. Suitable citrus fruits include, for example, lemons and / or oranges. According to a preferred aspect of the flow aid, the powder has a residual oil content of a maximum of 6% by weight, in particular a maximum of 3% by weight. The fruit seeds are preferably partially deoiled, in particular deoiled, before comminution, in particular before grinding. The partially deoiled, in particular deoiled, fruit seeds can be ground into powder in a simple and economical manner.In addition, the low residual oil content has beneficial effects on sensory aspects, especially when the flow agent is used in food products. All common methods can be used to deoil the fruit seeds, such as pressing, extraction using chemical solvents, especially n-hexane, and / or mechanical removal of the fatty germ by cutting out and / or squeezing. Deoiling by pressing, solvent extraction, and / or mechanical germ removal prior to pressing has proven particularly advantageous.

[0019] Alternatively or in addition to crushed fruit seeds from berries and / or soft fruits, the powder may contain crushed, especially ground, fibrous plant products. A plant product is understood to be, in particular, a component of a plant and / or a product obtained from the plant or its plant components, which arises particularly as a side stream, by-product, or waste product in industrial production. Suitable fibrous plant products include, for example, pomace, especially juice pomace, and / or fibrous plant stems.

[0020] According to a preferred aspect of the flow aid, the powder comprises comminuted, especially ground, fiber-containing plant products with a fiber content of at least 25 wt.%. The fiber content refers in particular to the proportion of raw fibers in the plant product. It has been found that a high fiber content is advantageous for the properties of the flow aid. The fiber content can in particular be at least 35 wt.%, preferably at least 50 wt.%.

[0021] Preferably, the fiber-containing plant products are dried. The residual moisture content can, in particular, be less than 10% by weight.

[0022] According to a preferred aspect of the flow agent, the powder contains, and in particular consists of, comminuted, especially ground, juice pomace. Juice pomace is a byproduct of juice production. Surprisingly, it has been found that powders made from juice pomace are suitable as flow agents.

[0023] The juice pomace preferably has a low acid content and / or a low sugar content. This improves the hygroscopic properties of the juice pomace powder. The acid content can, for example, be less than 6 wt.%, in particular less than 4 wt.%, preferably less than 2 wt.%. The sugar content is in particular less than 20 wt.%, in particular less than 15 wt.%, preferably less than 7 wt.%.

[0024] According to a preferred aspect of the flow aid, the powder contains, and in particular consists of, comminuted, in particular ground, dried, fibrous plant stems. The residual moisture content of the fibrous plant stems can in particular be less than 10 wt.%. Suitable plant stems are in particular plant stems of nettle, mint and / or chamomile, which arise, for example, in the production of corresponding tea blends. According to a preferred aspect of the flow aid, powder particles of the powder have a particle size distribution for which the following applies: Q3 (50) < 250 pm, in particular Q3 (50) < 100 pm, in particular Q3 (50) < 50 pm. Preferably, Q3 (50) > 0.1 pm, in particular Q3 (50) > 1 pm, in particular Q3 (50) > 10 pm, in particular Q3 (50) > 20 pm. Particularly preferred is: 20 pm < Q3 < 50 pm. Qs(50) describes the cumulative distribution, here the volume-related distribution, of the particle sizes in a particle mixture.The letter "Q" stands for quantile. The index "3" indicates that the distribution is volume-related. The value in parentheses specifies the proportion within the distribution. Qs(50) indicates that, in this case, 50% of the particles in the volume distribution are smaller or larger than the specified value.

[0025] It has been shown that smaller particle sizes are advantageous because they improve the surface coverage of the bulk particles. Firstly, the spherical packing of the powder particles on the surface of the bulk particles is higher. Secondly, a small powder particle size favors physical holding forces, such as the van der Waals force and electrostatic forces, over the force of gravity. A further advantage is that small powder particles have a higher surface area to volume ratio, which increases their ability to absorb moisture from the environment. However, smaller particle sizes require more complex manufacturing methods, particularly grinding, which leads to higher production costs. In addition, nanoparticles with a size of less than 100 nm must be viewed critically with regard to their approval for use in foodstuffs.

[0026] All common milling methods can be used to produce the powder, especially with the advantageous particle size distribution. It is also possible to obtain the powder by sieving from cutting processes in the production of smaller grain sizes of fruit seeds and / or fibrous plant products and / or by sieving from milling processes and other particle sizes.

[0027] The bulk material composition according to the invention, in particular for use in or as food or animal feed, comprises a bulk material and a flow aid, as described above. The bulk material composition is free-flowing even at high air humidity and temperature. The flow aid used can in particular have one or more of the advantageous properties described above. The bulk material can in particular be hygroscopic and / or have a fat content and a low dropping point. Sticking of the, in particular hygroscopic, bulk material is avoided even at high air humidity and / or high ambient temperature.

[0028] The bulk material is preferably hygroscopic. The hygroscopic properties of the bulk material can be determined, in particular, using the respective sorption thermal curve. Steep sorption thermal curves indicate highly hygroscopic behavior, while flat sorption thermal curves indicate weakly hygroscopic behavior. Hygroscopic behavior can be determined, in particular, according to the standard DIN 66138:2008-09 "Isothermal measurement of the sorption of vapors on solids."

[0029] In particular, hygroscopicity can be quantified by the percentage increase in weight resulting from water absorption during storage of a bulk material at different relative humidity values ​​after an equilibrium state has been reached. The increase in weight occurs at a set temperature, for example at 20 °C, from a certain relative humidity, for example from a relative humidity of greater than 44%. In particular, at a temperature of 20 °C and a relative humidity of up to 44%, the bulk material exhibits no water absorption, i.e. no increase in weight. Example values ​​of the relative weight increase at a temperature of 20 °C are described below. At a relative humidity of 53%, the weight increase is, for example, at least 4%, in particular at least 5%, in particular at least 7%.At a relative humidity of 75%, the weight gain is, for example, at least 15%, in particular at least 19%, in particular at least 23%. At a relative humidity of 84%, the weight gain is, for example, at least 24%, in particular at least 30%, in particular at least 35%.

[0030] According to a preferred aspect of the bulk material composition, the proportion of the flow aid in the bulk material composition is between 0.1 wt.% and 10 wt.%, in particular between 0.1 wt.% and 5 wt.%, preferably between 0.1 wt.% and 1 wt.%. A corresponding proportion has proven particularly suitable for increasing the flowability of the bulk material composition, in particular without influencing other properties of the bulk material composition, for example, without changing color and / or flavor.

[0031] According to a preferred aspect of the bulk material composition, the bulk material has a fat and / or oil content of at least 20 wt.%, preferably at least 60 wt. Such bulk materials are particularly prone to sticking. The flow aid has a particularly relevant effect for these bulk materials.

[0032] According to a preferred aspect of the bulk material composition, the bulk material has a dropping point of less than 60 °C, in particular less than 50 °C, preferably less than 30 °C. Such bulk materials are particularly prone to sticking, for example, at ambient temperature. The flow aid has a particularly relevant effect for these bulk materials. The dropping point can be determined, for example, according to the American Oil Chemists' Society (AOCS) standard AOCS Cc 18-80.

[0033] According to a preferred aspect of the bulk material composition, the flow agent comprises comminuted, in particular ground, rosehip seeds; in particular, the flow agent consists of these. The flow agent can particularly preferably be a powder made from ground rosehip seeds. The use, in particular exclusive, of rosehip seeds in the flow agent has proven particularly effective.

[0034] A food product according to the invention has the bulk material composition described above, in particular, it consists of the bulk material composition. The flow agent has proven particularly suitable for food products. It is particularly advantageous that the flow agent is obtained from natural ingredients. Any change in the appearance and / or taste of the food product is reduced, and in particular, avoided.

[0035] The bulk material, which is particularly hygroscopic, can comprise various foods and / or food ingredients. For example, the bulk material can be a mixture or a monopreparation for a herbal tea, a fruit tea, a green tea, or a black tea, in particular for a flavored fruit tea. The bulk material can also be a spice powder or a spice powder mixture. It is also possible, in particular, to use the bulk material composition in a ready-to-use food product, wherein the powder is, in particular, a dry baking mix, an instant soup powder, or a spice mix. Such ready-to-use food products, for example, instant soup powders, regularly have a high fat content, which can lead to sticking.

[0036] The food product according to the invention is, in particular, a tea blend, for example, a herbal tea, a fruit tea, especially a flavored fruit tea, a green tea, or a black tea. Teas, especially fruit teas, are particularly challenging to fill. Hygroscopic components, such as fruit pieces, in particular, change their rheological properties particularly significantly depending on humidity and temperature. Tea blends, especially fruit tea blends, therefore particularly benefit from the use of the flow agent.

[0037] According to a preferred aspect of the food in the form of a tea blend, in particular a fruit tea blend, the flow agent comprises crushed, in particular ground, rosehip seeds; in particular, the flow agent consists of these. Crushed, in particular ground, rosehip seeds have proven to be a particularly suitable flow agent, especially when pieces of fruit pulp, in particular rosehip pulp, are contained in the tea blend. According to a preferred aspect of the food in the form of a tea blend, in particular a fruit tea blend, the proportion of the flow agent in the tea blend is between 0.1% and 10% by weight, in particular between 0.1% and 5% by weight, preferably between 0.1% and 1% by weight.This proportion has proven to be particularly suitable for ensuring the flowability of the tea blend for different production conditions without significantly affecting the taste and / or appearance of the tea blend.

[0038] The bulk material composition can also be used in a feed and / or a pigment powder for the cosmetics or paint industry. The feed or pigment powder can, in particular, consist of the bulk material composition.

[0039] The object mentioned above is also achieved by using a powder made from crushed, in particular ground, fruit seeds of berries and / or soft fruit and / or from crushed, in particular ground, fiber-containing plant products as a flow agent in, in particular, hygroscopic bulk materials. The powder can be used in particular in tea blends or other foodstuffs, animal feed, and / or pigment powders. The advantages of using the powder correspond to those explained in connection with the flow agent. The powder used as a flow agent, the bulk material, and / or the resulting bulk material composition can exhibit one or more of the advantageous aspects described above.

[0040] According to a preferred aspect of the use, the powder used as an anti-caking agent comprises, and in particular consists of, crushed, especially ground rosehip seeds. Crushed, especially ground, rosehip seeds have proven particularly suitable, particularly due to their high water absorption capacity. Furthermore, rosehip seeds often remain as a by-product or waste product in industrial processes in the food or feed industry, for which—unlike many other fruit seeds—there are hardly any other possible uses. The rosehip seeds are further utilized through their use as an anti-caking agent, thus avoiding waste.

[0041] According to a preferred aspect of the use, a proportion of the flow agent, in particular the crushed rosehip seeds, in the bulk material composition is between 0.1 wt.% and 10 wt.%, in particular between 0.1 wt.% and 5 wt.%, preferably between 0.1 wt.% and 1 wt.%.

[0042] According to a preferred aspect of the use, the bulk material is a blend or a monopreparation for a tea, in particular for a fruit tea, for example, a flavored fruit tea. The use of flow agents in such teas is particularly advantageous.

[0043] According to a preferred aspect of the use, the flow agent comprises, and in particular consists of, comminuted, in particular ground, rosehip seeds, wherein a proportion of the powder, based on the resulting bulk material composition, is between 0.1 wt.% and 10 wt.%, in particular between 0.1 wt.% and 5 wt.%, preferably between 0.1 wt.% and 1 wt.%. According to a preferred aspect of the use, the mixture or the monopreparation for the tea, in particular for the fruit tea, contains fruit pieces, in particular apple pieces. For such tea mixtures, the use of the flow agent, in particular with the previously specified proportions, is particularly effective.

[0044] Further features, advantages and details of the invention will become apparent from the following description of an embodiment with reference to a figure.

[0045] Figure 1 shows a water absorption capacity of a flow aid according to the invention in comparison to the water absorption capacity of a previously known flow aid.

[0046] An example of an anti-caking agent consists of a powder made from ground rosehip seeds. The rosehip seeds were first deoiled so that their residual oil content was a maximum of 3 wt.%. The deoiled rosehip seeds were ground into a powder with a particle size distribution such that 20 pm < Qs(50) < 50 pm.

[0047] The resulting powder is excellently suited as a flow agent. In particular, the powder from ground rosehip seeds exhibits a high water absorption capacity. Fig. 1 shows a relative weight change AW as a function of the relative humidity (RH). The relative weight change AW is determined at a set relative humidity (RH) after equilibrium has been reached. A powder PI obtained from ground rosehip seeds is compared with rice starch P2. It can be seen that the relative weight increase of the rosehip seed powder PI is significantly higher than that of rice starch P2. This demonstrates that the rosehip seed powder PI can absorb significantly more water from the environment than the rice starch P2. The rosehip seed powder PI remains free-flowing even with high water absorption. The rosehip seed powder PI is therefore particularly well suited as a flow agent for hygroscopic bulk materials, such as tea blends.Rosehip seed powder PI is also particularly suitable as a flow agent in bulk materials with a low dropping point, for example, in fatty food or feed products. Another advantage of the flow agent based on ground rosehip seeds is that many relevant bulk materials, such as apple pieces, especially in fruit tea blends, have a similar color to rosehip seeds. Unlike rice starch, the addition of ground rosehip seeds does not cause a color change in these bulk materials.

[0048] The flow agent made from ground rosehip seeds is particularly suitable for food, animal feed, and pigment powder. Suitable food products include tea blends. Tables 1 and 2 list exemplary compositions of tea blends, in this case flavored fruit teas, containing the flow agent in the form of ground rosehip seeds (rosehip seed powder). The flow agent has a proportion of 1 wt.% in the composition. This has been found to be sufficient to ensure flowability even under adverse conditions (high humidity and high temperatures). The tea blends are particularly suitable for industrial filling, for example, into a double-chamber filter bag.
