Description

Methods for processing useful plants

[0001] The present invention relates to a method for processing leaves, fallen leaves, stems and bulbs of useful plants such as rice husks, rice stalks (rice straw), and bagasse, which is the residue left over from sugarcane extraction, into food and drink.

[0002] More specifically, rice husks, rice stalks, fruit skins and seeds, etc., with a diameter of 5 mm or less are dried, roasted and then crushed, while those with a diameter of 5 mm or more are dried, crushed and roasted, and then sterilized in a microwave or similar oven to prevent fermentation. Plants such as shell ginger, turmeric, scallions, onions, garlic and citrus fruits are blended, sterilized and flavored, and then a beverage can be easily produced using a paper drip method like coffee, or dried and powdered using a freeze-drying method or a dry-drying method, which can be vacuum-packed for long-term storage and used not only in peacetime but also in emergencies, making it a method of producing food and drink at low cost.

[0003] Although there are special methods, such as that described in Patent Document 1, for processing rice husks into ash so that it can be easily ingested orally, a processing method that can be easily and inexpensively realized using commonly available technology is desired.

[0004] JP 2021-166502 A

[0005] The technical content disclosed in Patent Document 1 is to produce inorganic rice husk ash for use as a food additive or supplement and to make it widely available to the general public, and to provide a method for producing rice husk ash in which optional inorganic components are attached to and supported on the surface of the rice husk ash, as well as an easy-to-use method, with the aim of further enhancing the unique effects of the rice husk ash.When producing rice husk ash by oxidative combustion, the rice husks are heated in an oxygen-poor state below a predetermined temperature to produce rice husk charcoal, and the rice husk charcoal is immersed in an aqueous solution of the desired inorganic component or a mixture of fine particles in water, and then oxidatively combusted at a predetermined temperature or below to remove organic matter, thereby producing rice husk ash with optional inorganic components attached to and supported on it.In addition, when using the rice husk ash, the rice husk ash is filled into capsules that are digested in the body and provided, making it easy to take orally.

[0006] As disclosed in Patent Document 1, there is technology to further improve the unique effects of inorganic rice husk ash when it is produced for use as a food additive or supplement and made widely available to the general public, but it is difficult to popularize this technology.

[0007] The present invention is realized by using common technology that is expected to be widely used to process leaves, fallen leaves, stems, and bulbs of useful plants such as rice husks, rice stalks (rice straw), and bagasse, the residue left over from sugarcane pressing, into food and beverages. In the case of ginger, turmeric, shallots, onions, garlic, and other plants, only the bulbs are used, with the leaves and stems being rarely used. Furthermore, the skins and seeds of fruits and other plants are rarely used, so these plants are also expected to be useful.

[0010] The structure described in [1] above is preferable. In this case, by drying, crushing, and roasting the rice husks to extract the components, the rice husks can be used for food and drink, and rice husk waste can be effectively utilized. Furthermore, by efficiently extracting the components of rice husks and processing them into food and drink without losing their nutritional value, it is possible to contribute to food diversification and the efficient use of resources. That is, this processing method effectively extracts the components of rice husks, thereby providing food and drink with high nutritional value and rich flavor. Furthermore, by changing the processing method depending on the diameter, optimal extraction efficiency and quality can be achieved and waste can be reduced. Furthermore, roasting improves the aroma and shelf life, allowing for a stable supply of products that meet consumer preferences. Furthermore, using a paper filter can remove impurities and produce a clear extract. The structure described in [2] above is preferable. In this case, by processing rice stalks (rice straw) in the order of drying, roasting, and crushing, rice components can be efficiently extracted while maximizing the retention of rice stalk components, and used for food and drink. Furthermore, rice straw waste can be effectively utilized. Furthermore, by adopting a processing method appropriate for the size of rice stalks, it is possible to prevent deterioration of ingredients and obtain a high-quality extract. In other words, this processing method maximizes ingredient extraction efficiency and enhances flavor and nutritional value by processing different diameter portions in different orders. Specifically, by drying and roasting the fine portions and drying and grinding the coarse portions before roasting, ingredients can be extracted approximately uniformly. Furthermore, using a paper filter removes impurities and produces a clear extract. The structure described in [3] above is recommended. In this case, freeze-drying or spray-drying techniques can be used to effectively extract and preserve useful plant ingredients, particularly those from rice husks and stalks. This allows for the production of dried powders containing valuable nutrients such as silica, which can be used as raw materials for food, beverages, and cosmetics while maintaining their quality. In other words, the flavor and nutrients of the food can be preserved while improving long-term shelf life and stability. The structure described in [4] above is recommended. In this case, the residue of the dried, roasted, and ground product or the dried, ground, and roasted product is dried and finely ground to be used as raw materials for food, beverages, and cosmetics.This allows the components of useful plants to be fully utilized without waste, and their nutritional value and functionality can be extracted and used in foods and cosmetics. Furthermore, waste residues can be effectively utilized. The structure described in [5] above is preferable. In this case, the residues after extracting the components from rice husks or rice stalks can be effectively utilized as feed or fertilizer, thereby reducing waste and promoting the effective use of resources. Furthermore, using the residues as feed or fertilizer is expected to improve the health of livestock and the growth of agricultural crops. In other words, environmental impact can be reduced and sustainable agriculture can be realized. The structure described in [6] above is preferable. In this case, the effective utilization of rice husks, which are normally treated as waste, has the effect of promoting the cyclical use of resources. Furthermore, by combining the drying, roasting, and crushing processes, the useful nutrients and functional substances contained in the rice husks can be maximized. In particular, the final fine crushing process improves digestibility and allows processing into a form that can be used directly in food or beverages. This potential for direct consumption enables the development of a wide range of applications such as health foods, functional foods, and food additives, creating value as a new food ingredient. The structure described in [7] above is preferable. In this case, the effective use of rice stalks, which are usually treated as waste, has the effect of promoting resource recycling. Furthermore, by combining the processes of drying, roasting, and grinding, the useful nutrients and functional substances contained in the rice stalks can be maximized. In particular, the inclusion of a fine grinding process improves digestibility and allows processing into a form usable directly for consumption. This usability for direct consumption enables the development of a wide range of applications as health foods, functional foods, or food additives, creating value as a new food ingredient. The structure described in [8] above is preferable. In this case, unused portions can be effectively utilized. For example, by drying, roasting, and grinding discarded portions of shell ginger or ginger, food components can be extracted and used for consumption. This reduces waste and promotes the effective use of resources. Furthermore, the extraction method using a paper filter enables simple and efficient production of food and beverages.Furthermore, it is suitable for providing food to impoverished areas. The structure described in [9] above is preferable. In this case, the effective utilization of various parts of plants that are usually treated as waste has the effect of promoting the recycling of resources. Furthermore, by combining the drying, roasting, and grinding processes, the useful nutrients and functional substances contained in each process can be maximized. In particular, the inclusion of a fine grinding process improves digestibility and allows processing into a form that can be used directly in food and drink. This usability for direct consumption enables the development of a wide range of applications such as health foods, functional foods, and food additives, creating value as a new food ingredient. The structure described in

[10] above is preferable. In this case, unused parts of useful plants, such as dead leaves, rice husks, and waste, are used as raw materials, or processed in the order of drying, roasting, and grinding if they are 5 mm or less in size, and drying, grinding, and roasting if they are 5 mm or more in size, to obtain the raw material components and process them into food and drink. Therefore, rice husks and dead leaves, which are generated in large quantities as waste, can be used as raw materials or dried, ground, and roasted, and then poured over with hot water to extract the rice husks and dead leaves components for consumption. The structure described in

[11] above is preferable. In this case, rice husks, which are generated in large quantities as waste, are used as raw materials. They are dried, crushed, and roasted, or dried, roasted, and crushed, and then hot water is poured over them using a paper drip machine or similar to extract the rice husk components for consumption. This allows for effective utilization of waste generated in large quantities. It is also suitable for providing support to those facing food and beverage shortages due to poverty. The structure described in

[12] above is preferable. In this case, hot water is poured over bagasse, the residue of sugarcane, to extract the slightly sweet liquid component, which is then added with seasonings or other optional ingredients, such as dried and crushed shell ginger, ginger, turmeric, scallions, onions, garlic, citrus fruits, etc., for consumption. This allows for the creation of a sweet edible product without the use of sugar. Moreover, beneficial components other than sweetness can also be ingested. The structure described in

[13] above is preferable. In this case, dried guava leaves or dried pine leaves are washed and then hot water is poured over them to extract the components, thereby enhancing their efficacy.Furthermore, since the leaves are dried by solar heat, there is no need to dry them, and natural energy is used to produce edible and beverage products. The structure described in

[14] above is recommended. In this case, hot water is poured over unused parts of shell ginger, ginger, turmeric, scallions, onions, garlic, and citrus fruits, i.e., leaves, stems, peels, seeds, etc., to extract their components. Therefore, the components of these unused parts can be extracted and effectively utilized. The structure described in

[15] above is recommended. In this case, unused parts of fruits, including mango, dragon fruit, loquat, and lychee, such as the peel and seeds, are dried and crushed, roasted, and then extracted with hot water using a paper drip method or the like. Therefore, the components of these unused parts can be extracted and effectively utilized. The structure described in

[16] above is recommended. In this case, hot water is poured over or infused into at least the unused parts of the banana peel, stem, or stalk to extract the components, resulting in a food or beverage product. Therefore, the components of at least the unused parts of the banana, such as the peel, can be extracted and used to produce a product. The structure described in

[17] above is recommended. Effectively utilizing coffee bean brew residue, which is typically discarded, can promote resource recycling. While coffee bean brew residue still contains many useful components, it has not been fully utilized until now. This method allows for the drying and further fine grinding of this residue, enabling it to be reused as a new food ingredient. In particular, the fine grinding process improves the bioavailability of the nutrients and functional substances remaining in the residue. Reducing particle size enhances digestibility and is expected to lead to more efficient utilization in the body. Furthermore, finely ground particles are more easily dispersed uniformly in beverages and foods, improving convenience during consumption. Processing coffee bean residue into a form suitable for direct consumption opens up a wide range of applications, including as a health food, functional food, or food additive. For example, coffee bean residue is rich in antioxidants and dietary fiber, and these components can be utilized to create new value as a food ingredient. Furthermore, this method also contributes to waste reduction in the food industry. Reusing coffee brew residue reduces waste disposal costs and environmental impact.

[0011] According to the present invention, useful plants, which are generated in large quantities as waste, can be used as raw materials by pouring hot water over them or by drying, grinding, and roasting them, and then extracting their active ingredients for consumption. By efficiently extracting these useful plants and processing them into food and drink without losing their nutritional value, it is possible to diversify food products and make effective use of resources.

[0014] Hereinafter, one or more embodiments specifically disclosing the method for processing useful plants according to the present invention will be described in detail with appropriate reference to the accompanying drawings.

[0015] However, more detailed descriptions than necessary may be omitted. For example, detailed descriptions of already well-known matters or redundant descriptions of substantially identical configurations may be omitted. This is to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art. Furthermore, each of the accompanying drawings should be viewed according to the direction of the reference numerals.

[0016] Furthermore, the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0017] Also, unless otherwise indicated, all numbers expressing parameters, reaction conditions, concentrations of ingredients, and so forth used in this specification and the appended claims are to be understood as being modified in all instances by the term "about." Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and appended claims are approximations that may vary depending, at least in part, on particular analytical techniques.

[0018] <Explanation of Terms> The terms "comprising" or "characterized by," which are synonymous with "comprising" and "containing," are to be interpreted in an inclusive or open-ended sense and do not exclude additional, unrecited elements or method steps. "Comprising" is a term of art used in claim language that means that the named claim element is required, but that other claim elements may be added to further form a structure within the scope of the claim.

[0019] Also, as used herein, the phrase "consisting of" excludes any element, step, or ingredient not specified in the claim. When the phrase "consisting of (or variations thereof)" appears in a section of the body of a claim rather than immediately following the preamble, it limits only the elements set forth in that section and does not exclude other elements from the claim as a whole. As used herein, the phrase "consisting essentially of" limits the scope of a claim to those elements or method steps specified in addition to those that do not materially affect the main and novel feature(s) of the claimed subject matter.

[0020] With respect to the terms "comprising," "consisting of," and "consisting essentially of," when one of these three terms is used herein, the presently disclosed and claimed subject matter may also include the use of either of the other two terms. Thus, in some embodiments not expressly recited otherwise, any instance of "comprising" may be replaced by "consisting of" or "consisting essentially of."

[0021] The term "process" or "step" may be used explicitly or implicitly in connection with process or method features, but no order or sequence is limited among such explicit processes or steps or among implicit processes or steps unless the order or sequence is stated.

[0022] <Processing methods using rice husks 1: Extraction for consumption> As shown in Figure 1, the bran layer and germ that cover the endosperm that becomes white rice are covered and protected by rice husks. Rice husks are produced in large quantities as a by-product during rice harvesting, but most of them are separated and discarded or are limited to low-value uses. However, rice husks are rich in nutrients such as dietary fiber, minerals, and vitamins, and have high potential nutritional value. Dietary fiber, in particular, is known to improve the intestinal environment and contribute to health promotion.

[0023] In an embodiment of the present invention, in order to effectively utilize the rice husks, they are washed, extracted with hot water, and consumed as tea (an example of "for consumption"), as shown in Figure 2. However, since extracting rice husks directly is inefficient, they are dried, crushed, and roasted to extract the components. Small rice husks such as rice husks can also be dried, roasted, crushed into powder, and then extracted.

[0024] As a specific example, a processing method according to an embodiment of the present invention includes the steps of sorting and washing rice husks, drying rice husks, crushing and particle size separation, roasting, final crushing, and extraction. An example of each step (each step of the processing method) will be described below.

[0025] [Processing steps] (Rice husk sorting and washing process) Rice husks that would normally be discarded are procured and sorted to remove foreign objects and impurities. They are then properly washed in running water to remove surface dirt and pesticide residues. This process is important to ensure the quality of the final product.

[0026] (Process of drying rice husks) After washing, the rice husks are placed in a dryer and thoroughly dried. By drying, the moisture content of the rice husks is reduced, which makes the processing process described below more efficient. The drying process may also be carried out by natural drying.

[0027] (Process of crushing and particle size separation) Dried rice husks are crushed in a crusher. After crushing, a particle size separator is used to separate the crushed material into particles with a particle size of 5 mm or less and particles with a particle size of 5 mm or more. Crushed material with a particle size of 5 mm or less is dried, roasted, and crushed, while crushed material with a particle size of 5 mm or more is dried, crushed, and roasted.

[0028] (Roasting process) After crushing and separating, the crushed rice husks are put into a roaster and roasted. The roasting process brings out the flavor and aroma of the rice husks.

[0029] (Final grinding process) After roasting, the rice husks are put through a grinder again to make them as finely powdered as possible. This process makes the particle size of the rice husks uniform, improving extraction efficiency. Specific examples of the fine grinding process will be described later.

[0030] (Extraction process) The final dry roasted and ground product and / or dry roasted and ground product is placed on a paper filter and extracted by pouring hot water over it. This allows the active ingredients of the rice husks to be efficiently extracted, resulting in a product suitable for consumption.

[0031] In this way, a flavorful extract for consumption can be efficiently obtained from rice husks. This processing method promotes the effective use of rice husks and also contributes to the reduction of waste. Using the rice husks, which are generated in large quantities, as a raw material, the ingredients are extracted using paper drip after roasting and used for consumption. Crushing makes it easier to extract the ingredients, and the residue after extraction can also be used as a soil conditioner or fertilizer.

[0032] Furthermore, the liquid containing the rice husk components obtained in the extraction step described above may be freeze-dried or spray-dried to extract at least the silica contained in the components, and the resulting dry powder may be used as a raw material for food, beverages, or cosmetics. An example of each of the freeze-drying and spray-drying methods will be described below.

[0033] [Freeze-drying method] The freeze-drying method is widely used as a food preservation and processing technique. The basic process involves freezing the target substance at a low temperature and then drying it by sublimating the water contained in the substance in a vacuum environment. This method is effective for preserving foods containing temperature-sensitive ingredients, and can prevent the thermal decomposition and deterioration of ingredients caused by heating. It also allows for drying while maintaining physical and chemical properties, making it excellent for preserving quality.

[0034] As an example of the specific process, the first step is to freeze the object at a low temperature. In this process, the object is rapidly frozen at an extremely low temperature. This freezes the water inside the object, preserving structures such as cell walls. This freezing reduces the size of the ice crystals, minimizing the destruction of cellular tissue. As a result, the texture and nutrients of the food are preserved.

[0035] In the second step, the frozen material is placed in a vacuum environment and a sublimation step is carried out, where the ice is converted directly into gas (vapor). This step is called primary drying, and almost all of the water inside the material is removed. In primary drying, ice sublimation is carried out in a low-temperature vacuum environment, and the temperature of the target material is kept below the freezing point, so the ice is converted directly into vapor without passing through a liquid state. This allows the shape and composition of the material to be maintained.

[0036] Secondary drying is performed after primary drying, where any remaining bound water is removed. Secondary drying is often performed by heating at low temperatures, reducing the final moisture content to 1% or less. This reduction results in a highly stable dry state of the material, improving the food's shelf life and allowing flavor and nutrient retention.

[0037] In the food industry, freeze-drying is used in a wide variety of applications. For example, coffee, fruits, vegetables, and meats are freeze-dried. These foods can be restored to a state close to their original state by adding water, so they are also used as emergency food and space rations. Freeze-dried foods are also lightweight, easy to carry, and can be stored for long periods of time.

[0038] In an embodiment of the present invention, the substance to be subjected to the freeze-drying process is a paper-dripped liquid containing rice husk components, as described above (the same applies to each of the useful plants described below).

[0039] Furthermore, freeze-drying can also be applied to the production of cosmetics or fragrances. In cosmetics, freeze-drying is used to improve the stability of products containing active ingredients, while in fragrances, freeze-drying is used to preserve fragrance ingredients for long periods without deterioration.

[0040] As such, freeze-drying is extremely effective in the preservation and processing of substances. This method not only preserves the quality and allows for long-term storage of substances, but also has excellent characteristics in terms of transportation and handling. In particular, freeze-drying is the optimal method for preserving and processing substances that are sensitive to temperature and humidity.

[0041] [Spray drying process] Spray drying is a process that converts liquid foods into fine particles to facilitate long-term storage and handling. The process involves dispersing the liquid into fine droplets and rapidly drying them using hot air to obtain a powdered product. Because spray drying quickly dries the liquid, it improves the food's shelf life while preserving its flavor and nutrients.

[0042] In one example of a specific process, the first step involves converting the liquid target into fine droplets. This involves using an atomizer or nozzle to disperse the liquid into a fine mist. The droplet size is in the micron range, which significantly affects the drying efficiency and the quality of the final product. Methods for generating droplets include spinning disk atomizers, ultrasonic atomizers, and pressure nozzles.

[0043] In the second step, the droplets are exposed to high-temperature dry air in a drying chamber. The droplets are instantly dried. This process allows moisture to evaporate rapidly from the droplet surface to the interior, preserving the flavor and nutrients of the target product. The flow of drying air can be set to flow in the same direction as the droplets (co-current) or against the direction (counter-current), which affects drying efficiency and product characteristics.

[0044] After drying, the droplets become powder-like particles, which are collected from the drying chamber using a cyclone separator or bag filter. The particle size distribution and shape of the powder depend on the droplet generation process and drying conditions. The final powder product must have a uniform particle size distribution and consistent quality.

[0045] Spray drying is widely used in the food industry, with typical applications including instant coffee, dairy powders (milk and whey protein), soup mixes, and fruit juice powders. These products are convenient because they have a long shelf life and can be reconstituted by adding water or other liquids.

[0046] In an embodiment of the present invention, the substance to be spray-dried is a paper-dripped liquid containing rice husk components, as described above (the same applies to each of the useful plants described below).

[0047] Furthermore, spray drying can also be applied to the production of cosmetics and fragrances. In cosmetics, powdered products containing active ingredients are produced, which improves the product's stability and usability. Similarly, spray drying is effective in the case of fragrances as a means of preserving the fragrance ingredients for long periods of time without deterioration.

[0048] As such, spray drying is used in a wide range of fields, and can rapidly dry liquid materials, improving their long-term storage and ease of handling. Furthermore, spray drying can preserve nutrients and ingredients, making it extremely effective in the preservation and processing of materials that are sensitive to temperature and humidity.

[0049] [Use of Residue] The residue of the dried roasted and ground product or the dried and ground roasted product, which is generated by the aforementioned processing method after the rice husk components have been extracted, is collected. In other words, the residue is the so-called leftover dregs of the dried roasted and ground product or the dried and ground roasted product. Since the extracted residue still contains active ingredients, it is dried again to remove moisture and then finely ground into an even finer powder. This final powder (an example of a "dried powder") still has nutritional value and can be effectively used in a variety of products. Examples of its use include use as a food additive or cosmetic ingredient.

[0050] Another example of how the residue can be used is as a raw material for chicken feed. In this case, the presence or absence of a drying process is not important. Specifically, the collected residue is transported to a chicken farm and mixed with chicken feed in an appropriate ratio. This mixing can improve the nutritional intake of chickens.

[0051] Another example of its use is to mix the residue with livestock manure (such as cows, pigs, and chickens) and use it as fertilizer for rice paddies. Specifically, the residue is mixed with livestock manure and fermented to create organic fertilizer. Applying this organic fertilizer to rice paddies promotes rice growth.

[0052] In this way, it is possible to effectively utilize the residue of rice husks (as well as each of the useful plants described below). This utilization reduces waste and promotes the effective use of resources. It can also contribute to improving the nutrition of poultry farms and the fertility of rice paddies. In other words, the present invention can contribute to convenience in many areas and environmental protection (SDGs).

[0053] <Processing method using rice husks 2: For direct consumption> In the processing method using rice husks described above, the rice husks are extracted for consumption, but here we will explain a method for producing a finely ground product that can be consumed directly.

[0054] In this method, rice husks are also used as raw materials.

[0055] First, the rice husks are washed to remove impurities, and then the rice husks are subjected to a drying process. Drying is carried out at a temperature ranging from 60°C to 80°C for approximately 1 hour to 12 hours. Alternatively, the drying process may be natural drying. This drying process reduces the moisture content of the rice husks to 10% or less.

[0056] Next, the dried rice husks are classified (sorted) by particle size. Rice husks with a diameter of 5 mm or less are roasted at temperatures ranging from 120 to 480°C for 15 to 180 minutes. After roasting, they are cooled and crushed into particles of approximately 100 to 200 mesh using a crusher.

[0057] On the other hand, rice husks with a diameter of 5 mm or more are first crushed to 5 mm or less using a crusher, and then roasted at a temperature range of 120°C to 480°C for 15 to 180 minutes.

[0058] The dried roasted and ground product and the dried and ground roasted product obtained through these processes are further finely ground (including ultrafinely ground) using a fine grinder to a size of 1 to 50 microns, or even less than 50 microns. This ultrafine grinding process increases the particle surface area and improves digestibility.

[0059] Fine grinding is a processing process in which a substance is crushed into very small particles using a grinder. In the present invention, this refers to grinding dry roasted and ground material or dry ground and roasted material into a fine powder of about 1 to 50 microns, which increases the surface area of ​​the particles and improves digestibility. Examples of grinders that can be used include ball mills, jet mills, pin mills, and hammer mills.

[0060] A ball mill is a device that crushes materials using, for example, metal or ceramic balls. A jet mill is a device that crushes particles by colliding them with high-pressure gas. A pin mill is a device that crushes materials using pins that rotate at high speed. A hammer mill is a device that crushes materials by striking them with hammers that rotate at high speed. Using these crushers, it is possible to effectively crush rice husks (including raw materials such as rice stalks, which will be discussed later) into fine or ultrafine powder, resulting in a powder that is highly digestible and absorbable. The choice of crusher is based on the target particle size, processing volume, and material properties.

[0061] In this method, it is also preferable to use a media-agitation type mill (e.g., a bead mill). A media-agitation type mill is a device in which a medium (a solid such as balls or beads) is filled in a gas such as air or a liquid such as water in the internal space of a housing such as a chamber or tank. The housing is then agitated at high speed, and the resulting impact force is used to finely grind the material. This method is particularly suitable for producing fine particles and ultrafine particles, and enables highly uniform particles and efficient grinding, making it a suitable device for the present invention.

[0062] The resulting fine powder can be consumed as is. For example, 0.2 to 1 gram can be dissolved in 100 milliliters of hot or cold water and consumed. It can also be added to yogurt or smoothies.

[0063] The rice husk powder processed using this method is rich in nutrients such as dietary fiber, minerals, and polyphenols, and is expected to have intestinal regulating and antioxidant effects. It also contains a large amount of silica, which may contribute to beauty and bone health. Silica (silicon dioxide, hereafter also referred to as "silicon") is a component found in abundance in rice husks and is a nutrient that may contribute to bone health and beauty (see below).

[0064] In this way, this method makes it possible to effectively utilize rice husks, which are usually treated as waste, and reuse them as a highly nutritious food ingredient. Furthermore, by optimizing the drying, roasting, and grinding processes, it is possible to produce a product for direct consumption that is highly digestible and absorbable while maximizing the retention of the useful components contained in the rice husks. In particular, the inclusion of a fine grinding process improves digestibility and makes it possible to process the rice husks into a form that can be used directly in food. This potential for direct consumption allows for the development of a wide range of applications, such as health foods, functional foods, or food additives, and can create value as a new food ingredient.

[0065] In addition to rice husks, rice stalks can also be used as raw materials. Furthermore, any one of (1) to (5) may also be used as raw materials. (1) Shell ginger, ginger, turmeric, scallions, onions, garlic, or citrus fruit leaves, stems, peels, or seeds; (2) Bagasse, which is the residue left over from sugarcane pressing; (3) Washed dried guava leaves or dried pine leaves; (4) Peel or seeds of mango, dragon fruit, loquat, or lychee; or (5) At least the peel, stem, or stalk of a banana.

[0066] Even when these are used as raw materials, by effectively utilizing various parts of the aforementioned plants, which are usually treated as waste, it is possible to similarly promote the cyclical use of resources, and to produce products for direct consumption that are highly digestible and absorbable, while maximizing the useful components contained in these raw materials.

[0067] In this way, the silicon contained in the raw material can be easily and efficiently ingested through the finely pulverized material. The advantages of ingesting silicon through the finely pulverized material according to this embodiment are as follows.

[0068] First, fine grinding reduces particle size, improving silicon bioavailability. This allows for more efficient utilization in the body. Furthermore, finely ground particles are more easily dispersed evenly in beverages and foods, improving convenience when ingested.

[0069] Because silicon contributes to improving bone density and strengthening connective tissue, efficient intake from finely ground material may contribute to maintaining healthy bones and joints. Furthermore, silicon promotes collagen production, which helps maintain skin elasticity and strengthen nails. These effects can be expected from intake from finely ground material. In other words, according to this method, silicon can be efficiently taken in from finely ground rice husks, which promotes collagen production and helps maintain skin elasticity and strengthen nails.

[0070] In addition, using natural plant-derived silicon sources can enhance safety compared to synthetic additives. Furthermore, using agricultural by-products as raw materials contributes to the efficient use of resources and the reduction of environmental impact. These advantages mean that ingesting silicon from finely ground materials is a beneficial method for both maintaining health and being environmentally friendly.

[0071] <Processing methods using rice stalks> Rice is primarily cultivated for harvesting rice, but its stalks (rice straw) are also used for many purposes. Rice stalks, in particular, contain a wealth of nutrients and have great potential value as a food. However, there are currently limited technologies for efficiently using rice stalks as food. Because rice stalks are tough and difficult to digest, improved processing methods are needed.

[0072] The same processing methods as for rice husks can be used on rice stalks. By using these processing methods, the rice stalks can be softened to make them easier to digest and absorb, and the highly nutritious components of the rice stalks can be used directly for food or drink, as ingredients for food or cosmetics, or as ingredients for poultry feed, or mixed with livestock manure for use as fertilizer for paddy fields.

[0073] In other words, the above-mentioned processing method can also be applied to rice stalks (rice straw), and this method makes it possible to utilize the nutrients contained in the rice straw as much as possible without waste, and also promotes the utilization of rice straw waste, thereby contributing to environmental protection.

[0074] <Processing methods using sugarcane bagasse> Sugarcane is squeezed and the juice is processed to make sugar, but the bagasse that is left over after squeezing is usually discarded or burned as fuel.

[0075] In an embodiment of the present invention, as shown in Figure 3, bagasse, the sugarcane pomace, is extracted by pouring hot water over it, either directly or after drying, grinding, and roasting, to produce a mildly sweet taste. While not sweet enough as sugar, it is suitable for those who prefer a milder sweetness or those who prefer less sweetness. This produces a sweetened liquid. Adding desired seasoning ingredients or other optional ingredients, such as ginger, turmeric, scallions, onions, garlic, or citrus fruits, to this liquid can produce a unique beverage. In other words, by selecting seasoning ingredients or other optional ingredients, desired flavors and colors can be achieved. The residue after extraction can be mixed into fields to function as fertilizer or soil conditioner. The steps shown in Figure 3 are similar to those described above, and therefore detailed descriptions are omitted.

[0076] <Processing method using dried guava leaves or dried pine leaves> Since this is an effective use of waste, it is desirable to be able to do so inexpensively. With rising prices these days, it is also important to keep energy costs, such as gas and electricity, low. Therefore, as shown in Figure 4, dried guava leaves or dried pine leaves, which are expected to have medicinal properties, can be washed, crushed, and their components extracted using a paper drip method to create a health drink. In particular, dried pine leaf tea from Iriomote Island is made naturally using solar heat, so no special energy costs are required. Each step shown in Figure 4 is similar to the steps described above, so a detailed explanation will be omitted.

[0077] <Processing method using banana peel, stalk, and stalk> Figure 5 shows a processing method using banana peel, stalk, and stalk.

[0078] Banana peels, which are usually discarded, and banana stems and stalks, which are thought to be inedible, can be easily extracted by drying, crushing, and roasting them, and the ingredients can be made into a delicious drink with a refreshing taste. Note that each step shown in Figure 5 is the same as the steps described above, so a detailed explanation will be omitted.

[0079] In addition, in the heating process using a microwave as shown in FIGS. 2 to 5, fermentation may be stopped or sterilized using a microwave after roasting, if necessary.

[0080] <Processing Method Using Residue After Coffee Bean Extraction> As an embodiment of the present invention, a method for producing a new food material using residue after coffee bean extraction will be described.

[0081] First, in a typical coffee extraction process, hot water is poured over ground coffee beans to extract the coffee components. The residue of the grounds remaining after this extraction process is the raw material for this embodiment. This residue has traditionally been disposed of as waste, but in this embodiment, it is effectively utilized.

[0082] Next, the residue after extraction is dried. Examples of drying methods include heating at a temperature of 60 to 80°C for about 2 to 4 hours using an oven or dryer, or natural drying. This drying process reduces the moisture content of the residue to 10% or less, preventing microbial growth and making the residue suitable for the subsequent fine grinding process.

[0083] After drying, the residue is finely ground. In this process, the coffee is ground to a particle size smaller than the original coffee grounds. Specifically, the coffee is ground using a high-performance grinder such as a ball mill or jet mill until the average particle size is 50 μm or less, preferably 20 μm or less. This fine grinding improves the bioavailability of the nutrients and functional substances remaining in the residue, enhancing digestibility and absorption.

[0084] The dried powder obtained after fine grinding can be used directly as an ingestible beverage. For example, it can be used as an ingredient in health foods, filled into capsules or tablets, or used as a base for powdered beverages. It can also be added to baked goods such as bread and cookies to develop functional foods enriched with dietary fiber and polyphenols.

[0085] Furthermore, this fine powder can be used as a flavoring ingredient to bring out the flavor of coffee. For example, by adding it to desserts such as ice cream, yogurt, and chocolate, it can impart the aroma and flavor of coffee while also increasing its nutritional value.

[0086] The fine powder obtained by the manufacturing method of this embodiment promotes the recycling of resources by effectively utilizing coffee extraction residue, which was previously discarded. At the same time, it maximizes the use of useful components contained in coffee beans, creating value as a new food ingredient. This contributes to reducing waste in the food industry and building a sustainable food production system.

[0087] The method of this embodiment can be applied not only to coffee extract but also to other plant wastes. For example, by applying it to tea extract, fruit pomace, etc., it is expected that various plant wastes can be effectively utilized.

[0088] In this way, this embodiment can simultaneously achieve effective use of resources, maintenance of nutritional value, diversification of food products, and reduction of environmental impact.

[0089] <Conclusion> Although one or more specific embodiments have been described above, aspects of the present invention are not limited to these embodiments, and modifications and improvements are possible as appropriate.

[0090] In other words, it is clear that a person skilled in the art can conceive of various modifications, alterations, substitutions, additions, deletions, and equivalents within the scope of the claims, and it is understood that these also naturally fall within the technical scope of the present disclosure. Furthermore, the components in the above-described embodiments may be combined in any manner as long as they do not deviate from the spirit of the invention.

[0093] The effects corresponding to each of [1] to

[16] are described below. [Effects of [1]] By drying, crushing, and roasting rice husks to extract their components, rice husks can be used for food and drink, and rice husk waste can be effectively utilized. Furthermore, efficiently extracting rice husk components and processing them into food and drink without losing their nutritional value can contribute to food diversification and the efficient use of resources. This processing method effectively extracts rice husk components, thereby providing nutritious, flavorful food and drink. Furthermore, by varying the processing method depending on the diameter, optimal extraction efficiency and quality can be achieved, reducing waste. Furthermore, roasting improves the aroma and shelf life, allowing for a stable supply of products that meet consumer preferences. Furthermore, using a paper filter removes impurities, resulting in a clear extract. [Effectiveness relative to [2] above] By processing rice stalks (rice straw) in the order of drying, roasting, and grinding, rice components can be efficiently extracted while maximizing the retention of rice stalk components and used in food and beverages. This also allows for effective utilization of waste material such as rice straw. Furthermore, by adopting a processing method tailored to the size of the rice stalks, degradation of components can be prevented and a high-quality extract can be obtained. Specifically, this processing method maximizes component extraction efficiency by processing different diameters of the rice stalks in different orders, thereby enhancing flavor and nutritional value. Specifically, by drying and roasting the finer parts and drying and grinding the coarser parts before roasting, components can be extracted approximately uniformly. Furthermore, the use of a paper filter removes impurities, resulting in a clear extract. [Effectiveness relative to [3] above] Freeze-drying or spray-drying techniques can effectively extract and preserve components from useful plants, particularly rice husks and stalks. This allows for the production of dried powders containing valuable nutrients such as silica, which can be used as raw materials for food and beverages and cosmetics while maintaining their quality. In other words, it is possible to improve the long-term storage property and stability of food while maintaining its flavor and nutrients.[Effectiveness relative to [4]] The residue of dried roasted and ground material or dried and ground roasted material is dried and finely pulverized to produce raw materials for food, beverages, and cosmetics. This maximizes the use of useful plant components without waste, extracting their nutritional value and functionality for use in foods and cosmetics. Furthermore, waste residue can be effectively utilized. [Effectiveness relative to [5]] By effectively utilizing the residue after extracting rice husk or rice stalk components as feed or fertilizer, waste can be reduced and resource utilization can be promoted. Furthermore, using the residue as feed or fertilizer is expected to improve livestock health and crop growth. In other words, environmental impact can be reduced and sustainable agriculture can be realized. [Effectiveness relative to [6]] By effectively utilizing rice husks, which are normally treated as waste, resource recycling can be promoted. Furthermore, by combining the drying, roasting, and pulverization processes, the useful nutrients and functional substances contained in the rice husks can be maximized. In particular, the final fine pulverization process improves digestibility and absorption, allowing the rice husks to be processed into a form that can be used directly for food and beverages. This direct consumption of rice stalks allows for the development of a wide range of applications as health foods, functional foods, or food additives, creating value as a new food ingredient. [Effective effects relative to [7] above] Effective utilization of rice stalks, which are usually treated as waste, promotes the recycling of resources. Furthermore, by combining the drying, roasting, and grinding processes, the useful nutrients and functional substances contained in the rice stalks can be maximized. In particular, the inclusion of a fine grinding process improves digestibility and allows processing into a form usable directly for consumption. This direct consumption of rice stalks allows for the development of a wide range of applications as health foods, functional foods, or food additives, creating value as a new food ingredient. [Effective effects relative to [8] above] Unused parts can be effectively utilized. For example, by drying, roasting, and grinding discarded parts of shell ginger or ginger, food components can be extracted and used for consumption. This reduces waste and promotes the efficient use of resources.Furthermore, extraction methods using paper filters enable simple and efficient production of food and beverage products. Furthermore, they are also suitable for food aid in impoverished areas. [Effective effects relative to [9] above] Effectively utilizing various parts of plants that are typically treated as waste promotes the recycling of resources. Furthermore, combining the drying, roasting, and grinding processes maximizes the preservation of the beneficial nutrients and functional substances contained in each process. In particular, including a fine grinding process improves digestibility and allows processing into a form usable directly for consumption. This usability for direct consumption enables the development of a wide range of applications, such as health foods, functional foods, and food additives, and can create value as a new food ingredient. [Effective effects relative to

[10] above] Unused parts of useful plants, such as dead leaves, rice husks, and waste, are used as raw materials, either as is or, if they are 5 mm or smaller, are dried, roasted, and ground, and if they are 5 mm or larger, are dried, ground, and then roasted. The raw material components are then extracted and processed into food and beverage products. Therefore, rice husks and dead leaves, which are generated in large quantities as waste, can be used as raw materials, either directly or after drying, grinding, and roasting. Hot water can then be poured over the husks or dead leaves to extract their components for consumption. [・Action and effect relative to

[11] above] Rice husks, which are generated in large quantities as waste, can be used as raw materials by drying, grinding, and roasting them, or by drying, roasting, and grinding them. Hot water can then be poured over them using a paper drip system or similar to extract the rice husk components for consumption. This allows for effective use of waste generated in large quantities. It is also suitable for providing support for those facing food and beverage shortages due to poverty. [・Action and effect relative to

[12] above] Hot water can be poured over bagasse, the residue from the squeezed sugarcane, to extract the liquid component, which retains a slightly sweet taste. The liquid component can then be added with seasonings or other optional ingredients, such as dried and ground shell ginger, ginger, turmeric, scallions, onions, garlic, or citrus fruits, for consumption. This allows for the production of sweet edible products without the use of sugar. Moreover, beneficial ingredients other than sweetness can also be ingested. [Effects of the above

[13] ] After washing the dead guava leaves or dead pine leaves, hot water is poured over them to extract the ingredients, so the efficacy of the ingredients can be expected.Furthermore, since the leaves are dried by solar heat, there is no need to dry them, and natural energy is used to produce edible and beverage products. [・Action and effect for

[14] ] Hot water is poured over unused parts of shell ginger, ginger, turmeric, scallions, onions, garlic, and citrus fruits, i.e., leaves, stems, peels, seeds, etc., to extract ingredients. This allows for the extraction and effective use of the ingredients from the unused parts. [・Action and effect for

[15] ] Unused parts such as the peel and seeds of fruits including mango, dragon fruit, loquat, and lychee are dried and crushed, roasted, and then poured over with hot water using a paper drip method or the like to extract ingredients. This allows for the extraction and effective use of the ingredients from the unused parts. [・Action and effect for

[16] ] Hot water is poured over or brewed over at least the unused parts of the banana peel, stalk, or stem to extract ingredients, resulting in a food or beverage product. This allows for the extraction and effective use of ingredients from at least the unused parts of the banana, such as the peel, to be commercialized. [Effects of

[17] ] Effective utilization of coffee bean brew residue, which is usually discarded, can promote resource recycling. Coffee bean brew residue still contains many useful components, but has not been fully utilized until now. In this configuration, the residue can be dried and further finely ground, allowing it to be reused as a new food ingredient. In particular, the fine grinding process improves the bioavailability of the nutrients and functional substances remaining in the residue. Reducing particle size is expected to improve digestibility and enable more efficient utilization in the body. Furthermore, finely ground particles are more easily dispersed uniformly in beverages and foods, improving convenience during consumption. Processing the residue into a form that can be directly consumed enables the development of a wide range of applications, such as health foods, functional foods, and food additives. For example, coffee bean residue is rich in antioxidants and dietary fiber, and these components can be utilized to create value as a new food ingredient. Furthermore, this method contributes to waste reduction in the food industry. Reusing coffee brew residue reduces waste disposal costs and environmental impact.

[0094] As described above, useful beverages can be produced cheaply from waste materials, and it is also suitable for supporting people who have recently become unemployed and are struggling to make ends meet. Furthermore, by effectively utilizing waste materials, agricultural income can be increased and the disposal costs of plants, which require huge amounts of capital and labor, can be reduced, contributing to industrial development.
