Description

[Technical field]

[0001] The present disclosure relates to a material that maintains the texture of a food or beverage, and a method for producing the same. [Background technology]

[0002] In addition to skins and seeds, the discarded parts of vegetables during cooking and processing are by-produced as cores, stems and leaves, bases of plants, petiole bases, root tips, nodes, etc. For example, the core of cabbage, which is considered to be a discarded part, constitutes about 15% of the fresh weight of the head of cabbage, and about 35% of broccoli inflorescences (raw) are discarded as stems and leaves (Standard Tables of Food Composition in Japan 2020 Edition (8th Revised Edition)).

[0003] On the other hand, these discarded parts do not pose any safety issues and contain parts with nutritional value such as minerals, vitamins, and dietary fiber. In order to make effective use of these parts, various ideas have been proposed, such as finely chopping the cores and stems and mixing them into dishes when cooking at home, or seasoning the cores and stems to make them into a dish.

[0004] In this way, efforts are being made to make effective use of discarded vegetable parts, mainly within the home, but since discarded parts are also produced in large quantities as processing residues at vegetable processing plants and the like, their use in the food and beverage industry is being considered. For example, cabbage cores and broccoli stems are produced in large quantities as by-products at sites that process large quantities of foodstuffs, such as vegetable processing plants, but since the period during which they can remain fresh is short and the processing residues need to be treated before they spoil, these discarded parts are also used as animal feed or treated as raw materials for compost before they lose their nutritional value.

[0005] On the other hand, there are growing expectations for technology to process cabbage cores into food and beverage ingredients with long shelf life, in order to make more efficient use of food resources. Summary of the Invention [Means for solving the problem]

[0006] While developing technology for advanced utilization of discarded vegetable parts, the inventors discovered that when discarded vegetable parts, which are harder than edible parts, are cut, dried, and then rehydrated, the texture of the material is similar to that of the original fresh food.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] The present disclosure will be described below while showing the best mode. Throughout this specification, the expression of the singular form should be understood to include the concept of the plural form, unless otherwise specified. Therefore, the singular article (for example, in the case of English, "a", "an", "the", etc.) should be understood to include the concept of the plural form, unless otherwise specified. In addition, it should be understood that the terms used in this specification are used in the sense commonly used in the field, unless otherwise specified. Therefore, unless otherwise defined, all technical terms and scientific and technical terms used in this specification have the same meaning as commonly understood by those skilled in the art to which this disclosure belongs. In case of conflict, the present specification (including definitions) will take precedence.

[0013] The following provides definitions of terms particularly used in this specification and / or explains basic technical content as appropriate.

[0014] As used herein, "about" means ±10% of the preceding numerical value.

[0015] In this specification, "inedible parts" refers to parts of food and beverages that are discarded in normal eating habits, and specifically refers to the discarded parts of individual foods in the "Standard Tables of Food Composition in Japan, 2020 Edition (8th Edition): Report of the Resource Survey Subcommittee of the Council for Science and Technology, Ministry of Education, Culture, Sports, Science and Technology, December 2020 (https: / / www.mext.go.jp / content / 20201225-mxt_kagsei-mext_01110_011.pdf)" and / or "Data from the Standard Tables of Food Composition in Japan, 2020 Edition (8th Edition) (20201225-mxt_kagsei-mext_01110_012.xlsx (live.com))". In addition, non-edible parts also include parts that are removed from the process of cutting for specific purposes during the production of processed foods (e.g., to homogenize shape and quality, improve suitability for transportation, etc.). Inedible parts also include parts that are edible but are excluded from the primary processing and distribution process for a specific purpose. Inedible parts include, but are not limited to, the following: Cabbage core, broccoli stems and leaves, cauliflower stems and leaves, Chinese cabbage base, lettuce base, asparagus base, burdock tip or petiole base, radish tip or petiole base, turnip petiole base, carrot tip or petiole base, lotus root node, bamboo shoot base, mushroom base, or mushroom stalk bottom

[0016] As used herein, "texture" refers to the skin sensation in the oral cavity, including the teeth and tongue, among the five senses felt when eating food (in this specification, "food" is used interchangeably with "foodstuffs", and "food" can also include beverages when referring to food). Specifically, texture refers to the chewiness, feel on the tongue, and smoothness down the throat, and these characteristics can be expressed by physical properties such as hardness and viscosity. Texture, together with other senses such as taste, is an important element in constituting "deliciousness". Texture can be evaluated, for example, using instrumental measurement methods using a dynamic viscoelasticity measuring device, a chewing model, etc., in addition to human tests.

[0017] Although texture can be evaluated using these instrumental measurement methods, there are no versatile methods for reproducing the complex movements in the oral cavity or measuring faint chewing sounds, so the foods to which these instruments can be applied are limited to foods with high homogeneity, etc. Therefore, texture is evaluated by measuring the main elements that make up texture and evaluating the differences shown by individual food samples.

[0018] The reasons why inedible parts are considered inedible despite being edible are that they have poor taste, are inhomogeneous, are connected to organs and tend to leave dirt behind (such as the base of the petiole of a radish), are difficult to process (such as the tips of radishes and carrots), and are hard. Inedible parts are harder than edible parts, so if they are processed and cooked under the same conditions as edible parts, they will remain hard, and conversely, if they are processed and cooked under conditions that soften the hard parts, the edible parts will be overly soft. For this reason, in many cases, the edible and inedible parts are first separated, and only the edible parts that can be used for high-quality cooking are used. The removed inedible parts can be softened to an appropriate softness by processing and cooking only the inedible parts. However, there are fewer processing and cooking patterns for cooking inedible parts than for edible parts, and it is also more time-consuming, so the use of inedible parts is not widespread. In particular, at vegetable processing plants and the like, inedible parts are recovered, processed, cooked, and softened until edible; however, there are no recipients who can quickly supply the highly perishable products and sell them as high-added-value products, and so they remain in low-level use.

[0019] The edible parts of raw foods and foods that have been boiled or fried have a moderately hard and crunchy texture. However, if these are dried to withstand long-term storage, it is extremely difficult to reproduce the crunchy texture after rehydration. In the present disclosure, by using inedible parts that are harder than edible parts, the hardness remains even after drying and rehydration, making it possible to provide a high-added-value material that can express a crunchy texture that is difficult to express with edible parts.

[0020] Therefore, in this specification, "hardness" can be cited as one of the indices for evaluating texture, and "hardness" can be evaluated, for example, by measuring the bite resistance during chewing, the generation of minute sounds, and the mechanical disintegration tendency of tissues.

[0021] In this specification, "palatability" refers to an inherent property of food and the overall sensation that a person experiences toward a food or drink when ingesting that food, which refers to a positive sensation toward the food, and is experienced by all five senses, including not only the taste itself (gustation), but also the appearance (sight), aroma (smell), texture (touch), sound when chewing (hearing), and the atmosphere and environment of the meal, and is a property that can be controlled by the characteristics of the food or drink.

[0022] In this specification, "texture" refers to the sensation of food perceived by the sense of touch, and "maintaining texture" refers to maintaining at least one of the physical properties of food originally possessed, such as chewiness, feel on the tongue, smoothness down the throat, or the hardness or viscosity that expresses these characteristics. Hardness and viscosity can be measured using a hardness tester, rheometer, Instron tester, Rapid Visco analyzer, Brabender Farinograph, texturometer, etc., and can be appropriately selected depending on the shape of the food sample, the measurable range, etc.

[0023] In this specification, "texture-maintaining material" refers to a material that maintains the chewiness, feel on the tongue, smoothness down the throat, etc. that a food originally had, and includes materials in which the texture of the material itself and / or the texture of the product obtained by allowing the material to absorb water recalls or is similar to at least one of the chewiness, feel on the tongue, smoothness down the throat, etc. that the food from which the material was made originally had, or physical properties such as hardness and stickiness that express those characteristics.

[0024] In this specification, "pulverization" refers to the operation of applying some energy to a food or drink (including solids, liquids, and mixtures thereof) in a solid form of a certain size to make it smaller than its original size. For example, there can be mentioned various processes such as micronization, fragmentation, destruction by impact, or grinding or crushing by shearing, and each process can increase homogeneity by mixing the ground material.

[0025] In this specification, the term "pulverized material" refers to a material obtained by pulverization.

[0026] In this specification, "cutting" refers to a process of cutting solid foods and beverages (including solids, liquids, and mixtures thereof) into smaller pieces than their original size, such as roughly cutting or finely chopping, among other types of pulverization.

[0027] As used herein, "a form that can be stored for a long period of time" refers to the form in which the food or beverage has been subjected to an inactivation process such as blanching to suppress the activity of enzymes that cause deterioration, and / or a drying process to suppress microbial activity and chemical changes.

[0028] As used herein, the term "long-term" refers to a period of at least one month.

[0029] In this specification, "pore size of about 0.5 mm" refers to a mesh with an opening size of about 0.5 mm, where the opening size refers to the vertical or horizontal width of a space (approximately square) per mesh formed by the intersection of vertical and horizontal lines in the mesh. Therefore, "pore size of about 0.5 mm" refers to a standard sieve wire mesh with an opening size of about 0.5 mm (30 mesh) according to the JIS standard.

[0030] In this specification, "passing through the mesh" means that ground, cut, or granulated food or beverage material passes through the space (approximately square) per mesh (hole) formed by the intersection of the vertical and horizontal lines in the mesh.

[0031] In this specification, "not passing through the mesh" means that ground, cut, or granular food or beverage material does not pass through the space (approximately square) per mesh (hole) formed by the intersection of the vertical and horizontal lines in the mesh, but remains on the mesh.

[0032] In this specification, "mesh passing fraction with an aperture of approximately 0.5 mm" refers to crushed, cut, or granular food or beverage material that passes through the space (approximately square) per mesh (hole) formed by the intersection of vertical and horizontal lines in the mesh with an aperture of approximately 0.5 mm.

[0033] In this specification, "approximately 10% or more by weight of particles of approximately 0.5 mm or larger" means that in a mesh with an aperture diameter of approximately 0.5 mm as described above, crushed, cut or granulated food or beverage material that remains on the mesh without passing through a space (approximately square) per mesh formed by the intersection of the vertical and horizontal lines is contained in an amount of approximately 10% or more by weight of the total material.

[0034] As used herein, "drying" refers to an operation to reduce the moisture content or increase the solids content, or the state resulting from that operation, and typically refers to a decrease in the moisture content of the entire food or beverage compared to before drying, or an increase in the ratio of solids to the total mass of the food or beverage compared to before drying.

[0035] As used herein, the term "dried form" refers to a food or drink whose total moisture content is about 20% or less.

[0036] As used herein, "B / A" or "B / A ratio" refers to the ratio of the value of B to the value of A below. (A) the amount of any one selected from citric acid, malic acid, and glucose released when the material is extracted with water at room temperature; (B) The amount of release of the same substance selected from citric acid, malic acid, and glucose selected from (A) when the material is extracted with hot water at about 60°C.

[0037] In this specification, "the release amount of the same thing as that selected in (A)" means that, for example, in the calculation of "B / A", when the release amount of citric acid is selected as (A), the release amount of citric acid is selected as (B).

[0038] (Preferred embodiment) Preferred embodiments of the present disclosure are described below. The embodiments provided below are provided for a better understanding of the present disclosure, and the scope of the present disclosure should not be limited to the following description. Therefore, it is clear that a person skilled in the art can make appropriate modifications within the scope of the present disclosure in light of the description in this specification. In addition, the following embodiments of the present disclosure can be used alone or in combination.

[0039] In one aspect of the present disclosure, a texture-maintaining material for food and beverages is provided, which is characterized by satisfying at least one of the following characteristics selected from the group consisting of: (i) being a pulverized product of food and beverages; (ii) containing at least about 10% by weight of particles of about 0.5 mm or larger; (iii) being in a form that can be stored for a long period of time; and (iv) containing a pulverized product derived from a non-edible portion of the food and beverages.

[0040] When recycling discarded or inedible parts of fresh vegetables as food materials, the biggest challenge is to ensure storage stability and increase added value. In particular, vegetables deteriorate over long-term storage, so it is necessary to effectively utilize the discarded or inedible parts that are by-produced in large quantities as processing residues in vegetable processing plants, etc. The texture-maintaining material for food and beverages disclosed herein can be provided as a material that maintains the texture of the original food and beverages.

[0041] To improve the storage life of vegetables, it is necessary to suppress deterioration caused by light and chemical changes, deterioration caused by enzymes in the vegetables, and spoilage caused by microorganisms. To date, processing methods such as sterilization, salting, sugaring, and smoking have been put into practical use depending on the characteristics of the processed product required, but drying is the most versatile processing method because it basically does not require additives, it can reduce water activity, it reduces weight, and it can be performed with only a drying device. In addition, drying is also used to preserve the edible parts of vegetables such as radishes.

[0042] Dried vegetables are dry and highly absorbent when eaten directly, so they are generally rehydrated in water or hot water, or mixed with a high-moisture material such as juice to absorb water, making them easier to eat. However, when rehydrated in water and recooked, for example, dried strips of daikon radish, although some of the nutrients, flavor, and fibrous texture remain, the crisp texture of the original food or drink is lost. In this way, dried fresh foods lose much of the texture that is characteristic of the original food or drink.

[0043] Even large cut pieces such as kiriboshi daikon radish become softened when they absorb water after drying, and cannot maintain the chewy texture of fresh foods. Dried vegetables that can be rehydrated in water or hot water also have a similar soft texture. Drying and crushing has the advantages of achieving high homogeneity, maintaining color and nutrients, and being easy to measure, but it also loses the texture of the original fresh food.

[0044] In vegetable processing plants, etc., edible parts are collected from washed agricultural products or from blanched materials to be processed into salads, frozen food ingredients, etc., and by selecting a fraction that is free from hygiene, texture, and taste problems from the inedible parts that are cut and separated at this time, food and beverage ingredients with added value can be obtained. Furthermore, this fraction can contain nutritional components and functional components.

[0045] When blanching this fraction, it is desirable to make it into as large a mass as possible in order to prevent the loss of water-soluble nutrients and other components. Blanching is a method of preventing undesirable changes such as discoloration, odor generation, softening, and deterioration of taste by inactivating the enzymes inherent in the material. The most common method is to immerse the material in hot water to pass heat, but since the degree of decrease in water temperature varies depending on the material temperature and the amount of immersion, it is desirable to select appropriate conditions. If the time is too long, softening, chemical deterioration, and component elution will be promoted. For example, it is common to immerse the material in boiling water for about 1 to 10 minutes. After this heat treatment, it is desirable to quickly return the temperature to a low temperature below room temperature in order to prevent chemical changes.

[0046] In one embodiment of the present disclosure, the food or drink or a fraction of the inedible portion of the food or drink after blanching can be in the form of a pulverized product, a form containing at least about 10% by weight of particles of at least about 0.5 mm, or a form that can be stored for a long period of time. In one embodiment, the form that can be stored for a long period of time can be a dried product or the like.

[0047] In one embodiment, since drying can be efficiently performed when the surface area of ​​the material is large, it is preferable to perform some cutting in a wet state. In particular, when the shape for long-term storage is to be plate-shaped, shredded, rectangular, disk-shaped, or dice-shaped, it is preferable to cut into the desired shape before drying shrinkage. In the material of the present disclosure, the shape of the pulverized material derived from the non-edible part can be plate-shaped, shredded, rectangular, disk-shaped, or dice-shaped, but is not limited to these shapes as long as the shape maintains the texture.

[0048] When obtaining a powdered dried product, the following methods can be used: (1) cutting the product in a wet state to produce a powder; or (2) roughly cutting the product into a shape that is easy to feed into a grinding device, drying the product, and grinding the dried product.

[0049] In one embodiment, the drying is not particularly limited as long as it is acceptable as a drying mode for food and drink, but can be achieved by drying at about 80°C or less, for example, thereby making the food and drink in a form that can be stored for a long time. In one embodiment, the drying method is not particularly limited as long as it is used for drying food and drink, but for example, known methods such as ventilation drying, natural drying, hot air drying, fluidized bed drying, spray drying, drum drying, low-temperature drying (drying in low-humidity air at about room temperature), vacuum freeze drying (freeze drying), pressure drying, electromagnetic wave drying, sun drying, shade drying, and drying in a fluidized bed can be used. In any method, the time, temperature, humidity, etc. can be appropriately changed depending on the type and size of the food and drink, and the desired degree of drying.

[0050] In one embodiment, when food or beverage is dried under harsh conditions, rapid browning or excessive shrinkage due to chemical changes may occur even after blanching, which may affect the quality, so it is preferable to dry the food or beverage under conditions of about 80°C or less, about 75°C or less, about 70°C or less, about 65°C or less, or about 60°C or less. Rapid drying may cause uneven drying or uneven shrinkage, which may cause deformation of the food or beverage. If the food or beverage is deformed and a closed space is created, the inside of the closed space becomes difficult to dry, and the risk of microbial contamination increases, so care must be taken not to dry too quickly. In one embodiment, the final dryness may be such that the water activity is sufficiently low and that water is not oriented to cause spoilage, but is not particularly limited as long as it is appropriate as the drying state of the food or beverage. For example, the final dryness may be about 20% or less, about 15% or less, about 12% or less, about 10% or less, about 8% or less, or about 5% or less in moisture content.

[0051] In one embodiment of the present disclosure, a known dry grinding device can be used to pulverize the dried inedible parts. Examples of such devices include those that use impact or shear with a blade or impact with a hammer, but are not limited to these as long as they can be used to pulverize foods and beverages. In one embodiment, when using a grinding method that uses a strong shear force such as grinding or a wet grinding method such as an extruder, it is preferable to use the device in a way that does not destroy the tissue structure or does not deteriorate the texture, as this promotes the destruction of the tissue structure and deteriorates the texture.

[0052] In one embodiment, in order to obtain a specific size of pulverized material from a non-edible part of a food or drink, a method of installing a mesh with a certain hole size at the discharge section of a pulverizer, a method of fractionating the pulverized material by passing it through meshes with various hole sizes, a method of fractionating it by air resistance, etc. can be used, but is not limited to these as long as it can obtain a pulverized material of a desired size. In one embodiment, the material disclosed herein can include a material that does not pass through a mesh with a hole size of about 0.5 mm. In another embodiment, the material disclosed herein can include a material that passes through a mesh with a hole size of about 1 mm but does not pass through a mesh with a hole size of about 0.5 mm.

[0053] In one embodiment, the material of the present disclosure may contain about 10% or more by weight of material that does not pass through a mesh with a pore size of about 0.5 mm. As shown in the examples of this specification, it has been found that a material containing about 10% or more of pulverized material with a particle size of 0.5 to 1 mm maintains the texture of the original food material, whereas a material containing about 5% of pulverized material with a particle size of 0.5 to 1 mm has a lower texture evaluation. Therefore, in one embodiment of the present disclosure, the inedible part is a cabbage core or a broccoli stem and leaf, and the material of the present disclosure may contain about 10% or more by weight of the dried pulverized material of the inedible part that does not pass through a mesh with a pore size of about 0.5 mm. In another embodiment, the inedible part is a cabbage core or a broccoli stem and leaf, and the material of the present disclosure may contain about 80% or more by weight of the dried pulverized material of the inedible part that does not pass through a mesh with a pore size of about 0.3 mm.

[0054] In addition, in one embodiment of the present disclosure, when pulverized materials having a large particle size are mixed with pulverized materials having a small particle size, the chewing sensation at the beginning of chewing is reduced due to the presence of the pulverized materials having a small particle size, but as chewing continues, the smaller fractions are washed away in the mouth, and the texture provided by the pulverized materials having a large particle size can be provided.

[0055] In one embodiment of the present disclosure, the material of the present disclosure can include a fraction that passes through a mesh with a pore size of about 0.5 mm, but does not pass through a mesh with a pore size of about 0.3 mm. In another embodiment, the material of the present disclosure can include a fraction that does not pass through a mesh with a pore size of about 0.3 mm, which is about 80% or more by weight. In one embodiment of the present disclosure, the material of the present disclosure can also include a fraction that passes through a mesh with a pore size of about 0.5 mm, which is about 90% or less by weight. In one embodiment of the present disclosure, the material of the present disclosure may be a cut product of an inedible part of a food or beverage, for example, a material may be provided in which the core of a cabbage or the stems and leaves of broccoli as the inedible part of a food or beverage are cut into a material having a thickness of about 1 mm or more. In this case, it is sufficient that the size of any side of the cut product is about 1 mm or more, and preferably, each side size is about 1 mm or more. In another embodiment, when a cut product of an inedible part of a food or beverage is used, a cut product having a thickness of about 1 mm or more in the growth axis direction of the core or stems and leaves can be used.

[0056] In the dried state, the inedible parts can be stored at room temperature, but in order to suppress chemical deterioration, the effects of light, and reorientation of water and volatile components due to partial heating and cooling, it is preferable to store them at the lowest possible temperature under light-shielded, oxygen-shielded, and / or low-humidity conditions. On the other hand, when samples that are not sufficiently dried are frozen and stored, shape changes and fractures due to ice crystal growth may occur, so it is preferable to perform drying as described elsewhere in this specification. In addition, since the shape of dried products may change during transportation and / or storage due to vibration or pressure, it is preferable to transport and / or store them in a way that does not cause shape changes.

[0057] In one embodiment of the present disclosure, when the dried inedible part is used as a food or drink, in order to impart a texture reminiscent of the original agricultural product, it is preferable to make the material of the present disclosure absorb water and moisten it during or before chewing. As shown in the examples of this specification, it was confirmed that the material returns to the shape of the tissue structure by absorbing water, and gives a crunchy texture reminiscent of or similar to the original agricultural product. This phenomenon is difficult to occur in edible parts that are originally soft, and can be achieved by using hard inedible parts. In one embodiment, the method of absorbing water is not particularly limited, but can be performed, for example, by rehydrating with water, seasoning liquid, or other water-containing foods during cooking processing, or by absorbing water with saliva in the mouth. Rehydration can be performed by immersing in water or hot water, or in those that have been subjected to a seasoning process, or by contacting with other foods and drinks or food and drink materials in a moist state. The soaking time can range from a few seconds to a few hours. However, if the amount of liquid is too large or the treatment time is too long, nutrients may leak from the inedible parts of the material or deterioration may progress. Therefore, the soaking time and the amount of liquid used for soaking can be adjusted appropriately depending on the size, shape, weight, etc. of the material.

[0058] In one embodiment of the present disclosure, the material of the present disclosure can maintain the texture of the original food or drink even if it is dried again after absorbing water once. Therefore, according to the material of the present disclosure, even if the powder of the material of the present disclosure is absorbed and seasoned, mixed with other ingredients, molded, and then dried, a characteristic texture derived from the non-edible part can be provided. This allows the powder of the material of the present disclosure to be processed to produce a dried or semi-dried food product molded into a rod, plate, disc, sphere, or any other shape. In addition, cut or dried products of non-edible parts can be provided with a texture reminiscent of or similar to the original food or drink by absorbing water and seasoning, and then drying or semi-drying again. In addition, according to the material of the present disclosure, it is also possible to produce a dried or semi-dried product by soaking a seasoning liquid or the like into the voids from which water has been removed from the dried food or drink or its pulverized product.

[0059] In one embodiment of the present disclosure, for example, the material of the present disclosure in a form to be stored for a long time can be made into a plate, shredded, rectangular, disk or dice shape, and absorbed water before or after drying to make it moist, and then further cut, pressurized and deformed, partially heated, or embedded with another material having a taste or texture, thereby modifying the characteristics of the material during mastication. Furthermore, by drying the material that has been subjected to such treatment, it can be made into a food or drink that can be stored for a long time.

[0060] Therefore, in one embodiment of the present disclosure, it is possible to provide a food or drink obtained by absorbing the texture-maintaining material of the present disclosure, or a food or drink obtained by absorbing a processed molded product of the texture-maintaining material of the present disclosure. In still another embodiment, it is also possible to provide a processed product obtained by drying such a food or drink.

[0061] In one embodiment of the present disclosure, the material of the present disclosure can be used as a material for a 3D food printer as a long-term texture-maintaining food ingredient. Until now, no method has been proposed for reproducing the texture of fresh food with materials for 3D food printing, and it is possible to impart not only the nutrition, color, and taste derived from non-edible parts, but also a new texture. The powder of the material of the present disclosure can be spread on a processing table and eaten directly as a dry powder, or it can be absorbed on the table as necessary to give it a texture. In another embodiment, before placing the powder of the material of the present disclosure on the processing table of the 3D food printer, it is also possible to absorb water and deliver it in a paste form. If the water absorption time is short or the particle size is large, and the binding property cannot be ensured, a suspension of disintegrated nata de coco or a thickening stabilizer can be used to promote the binding of the particles, making it easy to deliver and mold. The suspension of disintegrated nata de coco has a weak fiber texture, so that in addition to the chewing feeling of agricultural products, the dietary fiber texture can be enhanced. Therefore, in one embodiment of the present disclosure, a food or drink obtained by mixing the texture-maintaining material of the present disclosure with a suspension of bacterial cellulose can be provided. The powder can be bound by adding a suspension mainly composed of bacterial cellulose such as nata de coco cellulose or a thickening stabilizer, making the resulting food or drink easier to eat. In particular, by adding a suspension mainly composed of nata de coco cellulose, a fibrous texture can be imparted to the paste derived from the dried powder, and the texture of the original vegetable can be reproduced in terms of both the chewiness and fibrous texture. For example, a food or drink obtained by mixing a dried powder of cabbage core with a suspension mainly composed of nata de coco expresses a coleslaw salad-like or sauerkraut-like texture. In addition, this molding method can be used to produce processed foods in the form of rods, plates, spheres, etc., containing the dried powder derived from the discarded vegetable parts. Such food or drink is rich in dietary fiber, and the texture derived from the vegetables can be felt through the texture.

[0062] The material derived from the non-edible parts of the present disclosure as described above can be mixed with other ingredients or materials as necessary during or after water absorption to produce food and drink that is cooked, seasoned, and shaped. In addition, the texture of the material derived from the non-edible parts, such as dried materials, can be reproduced when eaten even if it is dried again after absorbing water. Therefore, when producing this food and drink, by adding moisturizing ingredients such as glycerol, sucrose, and trehalose, the re-dried powder does not harden, and the dryness when eaten can be reduced.

[0063] In one embodiment of the present disclosure, the material of the present disclosure that has absorbed water has a water resistance of about 1 kgf / cm 2 In one embodiment, the material of the present disclosure can be, for example, 10 mg of dry powder (water content: about 10%) is allowed to swell for 5 minutes or more by dropping 20 μL of tap water at room temperature, and the apparent area of ​​the material can be reduced to 0.5 cm. 2 Disperse the particles evenly so that the density becomes 1kgf / cm 2 After applying pressure for 3 minutes at 100° C., the powder is crushed and spread, resulting in an apparent area ratio of 130% or less. In the examples of this specification, it has been confirmed that when a load of 500 g is applied, the apparent area ratio is 124% or 125%, while in the case of a material other than that disclosed in this specification, the apparent area ratio is 149%.

[0064] In one embodiment of the present disclosure, the food or beverage that is the raw material for the texture-maintaining material of the present disclosure is not particularly limited as long as it is a food or beverage that produces a non-edible part as a by-product, and examples thereof include vegetables, fruits, grains, mushrooms, potatoes, sugar beets, beans, nuts, seeds, algae, and tea. Examples of the non-edible parts of each food or beverage include, but are not limited to, the core of cabbage, the stem and leaves of broccoli, the stem and leaves of cauliflower, the base of Chinese cabbage, the base of lettuce, the base of asparagus, the tip or petiole base of burdock, the tip or petiole base of radish, the base of turnip petiole, the tip or petiole base of carrot, the node of lotus root, and the base of bamboo shoots.

[0065] Also, in one aspect of the present disclosure, there is provided a method for producing a material that maintains the texture of the food or beverage when it absorbs water, the method comprising the steps of processing an inedible portion of the food or beverage into a long-term storage form, and pulverizing the inedible portion in the long-term storage form so that the minimum diameter is at least about 0.5 mm or more.

[0066] Inedible parts of food and drink can be made into a pre-processing sample in a form that can be stored for a long time, as necessary, by undergoing (1) a washing and separation process to reduce microbial contamination and foreign matter contamination, (2) a process to remove discolored or deteriorated parts, (3) a cutting process to improve the efficiency of heat treatment, physical processing, and drying, (4) a heating process to inactivate endogenous enzymes and sterilize, and / or (5) a cooling process to suppress deterioration due to heating. This pre-processing sample is preferably dried to a moisture content of 20% or less, more preferably 10% or less, and even more preferably 5% or less, using a known drying method used for fresh foods. The drying method can be one described elsewhere in this specification.

[0067] The inedible parts of the food and drink that have undergone these processes can be obtained in a long-term storage form cut into any structure. For example, the cutting method can be, but is not limited to, thin slices along the axial direction, ring slices in the cross-sectional direction relative to the axis, julienned or rectangular shapes, or diced shapes. Depending on the cutting method, characteristics such as the size consumed, drying speed, deformation during drying, and degree of loss of nutrients and other components can change, and individual characteristics can be given after re-absorption of water.

[0068] In one embodiment of the present disclosure, the inedible portion of the food or drink may be in the form of a dry powder. The powdering may be performed before or after drying. A known method may be used for the pulverization method. As a guideline for the degree of pulverization that can express the texture after re-absorbing water of the dried powder of the material of the present disclosure, the pulverization conditions that have a large ratio (B / A ratio) of the amount of hot water elution (B) to the amount of water elution (A) of intracellular substances such as organic acids including citric acid and malic acid and glucose can be mentioned. In the powder, tissues in a state where the cell wall structure is broken and the intracellular substances are easily leaked, and undisintegrated tissues in a state where the cell wall structure is only broken to a limited extent and the intracellular substances are maintained inside the cells are mixed, and when the undisintegrated tissue structure is disintegrated by hot water treatment, this ratio is considered to exceed about 1.0. In one embodiment, the powder of the material of the present disclosure can be a material in which this ratio is preferably greater than about 1.0, and more preferably, it may be greater than about 1.2 or about 1.4. Therefore, in one embodiment, the ratio (B / A ratio) of the amount of the same substance selected from citric acid, malic acid, and glucose selected from (A) when the material of the present disclosure is extracted with water at room temperature to the amount of the substance selected from citric acid, malic acid, and glucose selected from (A) when the material is extracted with hot water at about 60° C. can be at least about 1.0, about 1.1, about 1.2, about 1.3, about 1.4, about 1.5, about 1.6, about 1.7, about 1.8, about 1.9, or about 2.0. In one embodiment, the material of the present disclosure can have a B / A ratio of at least about 1.0 for any one substance selected from citric acid, malic acid, and glucose.

[0069] The present disclosure has been described above by showing preferred embodiments for ease of understanding. The present disclosure will be described below based on examples, but the above description and the following examples are provided for illustrative purposes only and are not provided for the purpose of limiting the present disclosure. Therefore, the scope of the present disclosure is not limited to the embodiments or examples specifically described in this specification, but is limited only by the scope of the claims. EXAMPLES

[0070] (Example 1: Drying and crushing cabbage leaves and cores) Cabbage leaves were cut into 3 cm cubes with a knife and immersed in tap water. The drained samples were then blanched in boiling water for 2 minutes, and immediately cooled in ice water after heating. After draining again, approximately 400 g of the samples were spread thinly on each of four trays in a dryer (SM4S-EH, Kihara Manufacturing Co., Ltd.) and dried at 60°C until the mass change became constant.

[0071] The cabbage was divided vertically into two parts, and only the core was cut out with a knife. It was then blanched in boiling water for one minute, and immediately cooled in ice water after heating. The pieces were cut into cubes of approximately 5 mm square, arranged on a tray, and dried in a dryer (SM4S-EH, Kihara Manufacturing) at 60°C until the mass change was constant.

[0072] The broccoli stems were cut with a knife. They were then blanched in boiling water for 5 minutes, and immediately cooled in ice water after heating. They were then cut into cubes of approximately 5 mm square, arranged on a tray, and dried in a dryer (SM4S-EH, Kihara Manufacturing) at 60°C for 24 hours.

[0073] The dried samples were pulverized using a cutter mill grinder (MF 10.1 cutter head, IKA Japan KK) and collected as samples that passed through a screen mesh with a pore size of 2 mm, 1 mm, or 0.5 mm. For fine pulverization, samples were pulverized at room temperature for 1 minute using a food mill (TML180, Tescom Co., Ltd.) and collected, and it was confirmed that almost all of the samples had a particle size of less than 0.3 mm.

[0074] (Rating 1) To improve handling, 250 μL of a 1:1 volumetric mixture of tap water and a puree-like mixture obtained by mixing (1-3),(1-4)-β-glucan and desugared nata de coco (referred to as "nata puree" in this specification: Tokuyasu K., et al. (2021) J. Appl. Glycosci. doi:10.5458 / jag.jag.JAG-2021_0009) was added to 100 mg of each ground material. After leaving the mixture at room temperature for 2 hours, one spoonful of the mixture was scooped up with a spatula and chewed in the mouth with four upper and four lower incisors. The intensity of the crunchy sound after the first few chews, the intensity of the sound after 100 chews, and the amount of remaining sound after 100 chews of the sample placed in the mouth were evaluated on a four-point scale from 0 to 3 (strong 3, weak 2, barely noticeable 1, not noticeable 0). For Onizaki sesame seeds (white), the initial (maximum) score was 3, the remaining value after 100 chews was 1, and the remaining amount was 1. The results are shown in Table 1. [Table 1]

[0075] (Evaluation 2: Mesh separation) 250μL of water was added to 100mg of each ground product, and after leaving it to stand at room temperature for 2 hours, one spoonful of this preparation was scooped up with a spatula and chewed in the mouth with four upper and lower incisors in the same manner as in Evaluation 1. The intensity of the crunchy sound after the first few chews, the intensity of the sound after 100 chews, and the degree to which the sample remained in the mouth after 100 chews were evaluated on a four-point scale from 0 to 3 (Table 2). [Table 2]

[0076] (Example 2: Core length and width) The cores were collected from the cabbage and the stems from the broccoli. They were then immersed in boiling water for 2 minutes (cabbage) or 5 minutes (broccoli), quenched under running water, and returned to room temperature. They were then hollowed out in the height direction (vertical direction Lo) or horizontal direction (radial direction Ra) using a cork borer with an inner diameter of 10 mm, after which each cylindrical sample was cut into 1 mm thick coins and dried at 60°C for 16 hours (referred to as "Ra coins" and "Lo coins", respectively).

[0077] The cabbage Ra coins shrunk significantly, while the Lo coins shrunk only slightly. Both broccoli coins shrunk slightly. When these dried pieces were rehydrated with a small amount of tap water and chewed with four upper and four lower incisors, the Ra had a more fibrous texture similar to that of kiriboshi daikon, while the Lo had a crunchy texture (detected as a sound when chewing).

[0078] (Example 3: Core shaping) The core was removed from the cabbage and the stem from the broccoli. They were then soaked in boiling water for 2 minutes (cabbage) or 5 minutes (broccoli), then quenched under running water and returned to room temperature. The whole was then cut horizontally (in vertical slices) into pieces approximately 5 mm wide. A pattern was engraved on each piece with a knife and it was then dried at 60°C for 16 hours. It was then rehydrated in tap water and chewed with four upper and four lower incisors. It had a crunchy texture (detected as a sound when chewing) (Figure 1).

[0079] (Example 4: Roughly cutting the core) The core was collected from the cabbage and the stem from the broccoli. They were then soaked in boiling water for 2 minutes (cabbage) or 5 minutes (broccoli), then quenched under running water and returned to room temperature. They were then cut horizontally (in vertical slices) into pieces approximately 2 mm wide. In the case of cabbage, the coin-shaped pieces were cut into parallel lines 5 mm wide to obtain strip-shaped samples. These were then dried at 60°C for 16 hours, rehydrated in tap water, and chewed with four upper and four lower incisors (Figure 2).

[0080] As a result, it was revealed that these samples had a crunchy texture (detected as the sound made when chewing), and in the case of cabbage, a material with a crunchy texture similar to that of dried daikon radish was obtained.

[0081] Example 5: Powder Molding 1 g of powder derived from cabbage core (sample B in Example 1) was taken and mixed with 2.5 mL of water or a puree-like mixture obtained by mixing (1-3), (1-4)-β-glucan and desugared nata de coco (referred to as "nata puree" in this specification: Tokuyasu K., et al. (2021) J. Appl. Glycosci. doi:10.5458 / jag.jag.JAG-2021_0009), formed into a plate of about 2 cm wide, 3 cm long, and 5 mm high, and then dried at 60 ° C. In addition, a mixture of nata puree and 6 g of powder in the same mixing ratio was extruded into a rod shape using a 10 mL plastic with a thickened injection part cut, placed on a flat surface of a stainless steel mesh, or placed on a spoon-shaped wire mesh mold and dried at 60 ° C. (Figure 3). Chewing these provides a crunchy sensation, and the nata puree additive adds a fibrous texture derived from the nata de coco.

[0082] Example 6: Extract Quantification The samples used were those prepared in Example 1. Previously mentioned samples are indicated with the same alphabet.

[0083] Malic acid and citric acid determination: After 10 μL of the sample solution was dried in vacuum, 25 μL of acetone solution with a triethylamine concentration of 15 μL / mL mixed with butyric acid (0.08 μL / mL) as an internal standard was added. After leaving it at room temperature for 10 minutes, 15 μL of acetone solution with a phenacyl bromide concentration of 30 mg / mL was added, and it was left at 40°C for 60 minutes. After drying the acetone solution with nitrogen gas, 1 mL of acetonitrile was added to make the HPLC sample solution.

[0084] The HPLC conditions were as follows: column Wakopack 5C8 HG (Fujifilm Wako Pure Chemicals) 4.6 mm x 250 mm, 5 μm, analysis was performed at room temperature. The detection wavelength was 254 nm, and the flow rate was 1.0 mL / min. Solution A: 25 mM sodium phosphate buffer (pH 2.0) and solution B: a 7:6 mixture of methanol and acetonitrile were run. The analysis was performed with an initial concentration of solution B of 28% for 5 minutes, linearly increasing the concentration from 55 to 70% over 5 to 21 minutes, and then maintaining it at 70% for 30 minutes. The quantitative values ​​of malic acid and citric acid were calculated from the calibration curve.

[0085] Glucose Measurement: Measurements were performed using a commercially available glucose measurement kit (Glucose CII-Test Wako: Fujifilm Wako Pure Chemical Industries, Ltd.). The results are shown in Tables 3 to 5. [Table 3] [Table 4] [Table 5]

[0086] Example 7 In this example, (D), (E), and (F) in Example 1 are represented as 1, 2, and 3, respectively (1 to 3 in circles in Figs. 4 and 5). 10 mg of samples 1 to 3 were taken and placed on a slide glass (4.6 g) in the shape of a disk with a diameter of 8 mm. 20 μL of tap water was dropped onto this sample and allowed to swell at room temperature for 5 minutes. Then, a slide glass was placed on top of the lower glass so as to overlap it, and the sample was held for 5 minutes to observe the deformation of the sample (A). Then, a 500 g weight was placed on the glass and held for 3 minutes, after which the weight was removed, and the sample deformation was observed after 1 minute (B). Furthermore, two 500 g weights were placed on top of each other on the glass and held for 3 minutes, after which the weights were removed, and the sample deformation was observed after 1 minute (C). After that, three 500 g weights were placed on top of the glass and held there for three minutes, after which the weights were removed and the deformation of the sample was observed one minute later (D).

[0087] As a result, the spread (area) of the samples is as shown in Figures 4 and 5. In samples 1 and 2, the lateral spread due to compression of the water-swollen samples was suppressed, and some grains maintained their shape. The fact that the grains were difficult to break suggests that strong chewing force is required to break them. In sample 3, the grains spread after treatment B. This suggests that coarse powders are difficult to disintegrate, retain their texture, and require force to chew the grains.

[0088] (Example 8: Food and drink processing example 1) To 40 g of spaghetti salad with ham and vegetables (Yamazaki Co., Ltd., Haibara-gun, Shizuoka Prefecture), 3 g of the cut and dried cabbage core from Example 4 (stored at room temperature and protected from light for 70 days) was added and mixed with twice the amount of water at room temperature for 30 minutes (Figure 6). This food product had a chewy texture derived from the cabbage core when chewed, and a crunchy sensation could be felt in the mouth.

[0089] (Example 9: Food and drink processing example 2) To 40 g of bacon potato salad with black pepper and whole grain mustard (Yamazaki Co., Ltd., Asahikawa City, Hokkaido), 3 g of the cut and dried broccoli stems and leaves from Example 4 (stored at room temperature and protected from light for 70 days) was added and mixed with twice the amount of water at room temperature for 30 minutes (Figure 7). This food was given a chewy texture derived from the broccoli stems and leaves when chewed, and a crunchy feeling was felt in the mouth.

[0090] (Example 10: Food and drink processing example 3) The condensed materials of the cabbage core-derived material and the broccoli stem and leaf-derived material obtained in Examples 8 and 9 were mixed together in an amount of 1.5 g each, then the mixture was fried on a heated iron plate covered with oil, and a sprinkling of salt was added to produce chewy stir-fried vegetables.

[0091] (Example 11: Food and drink processing example 4) 1.00 g of cabbage core powder sample (sample B in Table 1) was mixed with 5.00 g of dried mashed potato flakes (Hokkaido Jaga Mash, Calbee Potato Co., Ltd., Obihiro City, Hokkaido), and then mixed with 20 mL of water. This was covered with plastic wrap on a plate and heated in a microwave oven at 500 W for 30 seconds (Figure 8). This produced a food product in which powder derived from cabbage core, which has a texture similar to that of mashed potato, was dispersed.
