Description

Technical Field [0001] The present invention relates to a method for producing resistant starch-enriched rice,

The present invention relates to a method for producing rice with an increased content of resistant starch which can be used in functional feeds for companion animals.

Pet food means pet food. The most common are canned foods such as cat food and dog food. The kinds of canned cat food include fish meat (fish such as bluefin tuna, salmon, trout, mackerel) only and fish meat with poultry, cereals, vegetables, vitamins, minerals and fragrances. The sterilization conditions were 75 minutes at 115.6 ℃ for Tuna No. 2 and 90 minutes at 115.6 ℃ for Tube No. 4. Since the moisture content of the product is related to the protein content, the target is always 70 ~ 71%.

Pet feeds are also called specialty feeds (special purpose products). Refers to a special purpose feed produced by a special method in a separate production facility that is different from conventional livestock feed production. It is prepared by adding special purpose feed materials such as coloring agents, anticoagulants, binders, flavors, and antioxidants.

There is a need to look at animal feed nutrition to understand companion animal feed.

Animal Feed Nutrition (animal nutrition) is an academic study of various nutritional and nutritional phenomena occurring in the body by feeding animals to animals.

Animal must constantly receive adequate nutrients from outside the body to sustain life, to create new tissues, or to continue producing milk, meat, and eggs. In particular, feeds for industrial animals should contain all kinds of nutrients that are necessary to maximize the animal's genetic potential. Therefore, it is essential to understand the chemical and nutritional characteristics of each nutrient and the metabolism of nutrients in the body. It is also necessary to know the nutrient content and characteristics of each ingredient that constitutes the feed and the feed that feeds the animal, the physiological characteristics of each animal, and the nutrient requirements for each growth stage.

Animal nutrition (animal nutrition) is the study of all the processes that an animal consumes from the outside to use nutrients and excretion of waste products through a series of metabolic processes. In particular, Is called animal feed nutrition. In recent years, as the discipline has developed, it has been divided into monogastric animal nutrition (ruminant nutrition) and ruminant nutrition (ruminant nutrition) depending on the type of animal to be studied.

Unit animal nutrition is the study of animals with one stomach in the digestive organs, poultry nutrition (poultry nutrition), swine nutrition (swine nutrition), and other laboratory animal nutrition Laboratory animal nutrients, and fish nutrients.

Ruminant nutrition is a study of the nutrition of animals with four stomachs in the digestive tract. Typical examples are dairy cattle nutrition, beef cattle nutrition, beef cattle nutrition, , Goat, deer, etc., and the stomach is like a unit animal, but horses and rabbits that have similar digestive physiology to ruminants are classified as non-ruminant herbivores (non-ruminant herbivores).

Nutrition is the birthplace of animal food and nutrition, and its development has developed rapidly since the early eighteenth century, when ancient Greek scholars established theoretical hypotheses. Carbohydrate studies were first carried out by Antoine-Laurent de Lavoisier in 1777 and the starch was named in 1812 after identifying the relationship between O2 and CO2 by respiratory loss and body heat loss. In 1844 Schmidt Carbohydrates were defined by Schmidt. Proteins have evolved as amino acids were discovered in 1820 and proteins were named by Gerardus Johannes Mulder in 1839. Local studies were carried out by Knoop in 1904, (β-oxidation).

The first of the nutrients of life, carotenoids, fats, and proteins, were the focus of attention for their importance and deficiencies. In the early nineteenth century, people became aware of the lack of single nutrients and found that at least a simultaneous supply of protein, fat and carbohydrates was necessary. Mineral substances (minerals) began to be recognized as nutritionally important since the presence and importance of calcium in bones and teeth in the early 18th century has been revealed. As the research continued, the use of today's trace minerals, minerals balance in the body , And minerals have been extensively studied.

By the end of the nineteenth century, nutrition was primarily concerned with carbohydrates, fats and proteins and some other minerals. In the 1930s, the existence and function of essential amino acids became known and a new basis for the development of nutrition was established. The study of vitamins began with the announcement of the existence of vitamins by Casimir Funk in the early 20th century, and by 1940 most vitamins could be isolated, extracted and artificially synthesized. Thus, we now know that there are more than 110 necessary nutrients, and there is considerable research on these. As the modern nutrition develops, nutrients in the animal body are largely classified into carbohydrates, fats, proteins, vitamins, and minerals.

Regarding animal specification standards, the announcement of hay hay in the early 18th century can be considered a prelude. In the meantime, the researches focused on the physiological and biochemical actions of various nutrients in animal body tissues. Recently, a number of studies have been carried out on factors affecting nutrient interactions, nutrient digestion and absorption mechanisms, nutrient bioavailability and metabolism. In this way, many researches have been carried out to set the nutrient requirements for various animals in terms of their physiological and growth stages and production capacities. Specification standards for animals have been established, revised and supplemented, and nutrient requirements of almost all animals have been determined.

The development of such nutrition has been accompanied by the steady efforts of many scholars, achievements and advances in the application of various laboratory animals and related studies for research.

First, various kinds of animals and experimental animals were used for research, which contributed greatly to the creation and development of new theories. A typical example is as follows.

(A) Rats: Development of theories and knowledge on vitamins, amino acids, and minerals

(B) Dog: discovery of insulin, function of niacin

(C) Guinea pigs: Causes and treatment of scurvy

(D) Chicks: A study on the discovery of thiamin and the nutritional function of other vitamins

Various microbes also contributed to the development of nutritional science by studying various growth factors, analyzing various nutrient contents and evaluating the quality of feed.

Secondly, knowledge of how various nutrients are decomposed, synthesized and metabolized in the body through the basic biochemistry and organic chemistry, and the separation, determination and synthesis of various nutrients And provided a scientific basis for explaining various phenomena. And genetics has helped research on the production of new strains of microorganisms or lower animals, nutrient availability and varietal differences in nutrient requirements. The metabolism of nutrients and the analysis of trace elements in the stomach of ruminants can be explained by the help of microbiology (microbiology), the help of cytology (cytology) I had to get. Physiology also contributed to the development of nutrition by helping to understand the digestion and absorption mechanism of animal nutrients.

In particular, the development of diverse basic sciences has brought the level of nutritional science to a new level by bringing in new science and technology and the development of research instruments. For example, X-rays and spectrophotometers based on physics, amino acid analyzers, gas chromatography, bomb calorimeters, NIRS and NMR spectroscopy, Which directly affected the development of many devices important for nutritional development.

Animal digestive organs are an area where animals can digest and are an important part of studying animal nutrition. Here, the digestive organs refers to the mouth to the anus. Depending on the type of animal, the digestive organs have different structures and capacities, and their functions are somewhat different. However, the main function is ingestion, chewing, digestion, absorption and excretion of feed. In general, livestock digestion is divided into mechanical, chemical, and secretory digestion.

Mechanical digestion refers to the action of mastication in the oral cavity, mixing, transport and muscle contraction in the digestive tract, chemical digestion by digestion by bile in the stomach and digestion by digestive enzymes in the stomach It means digestion. And secretory digestion refers to the indirect action of digestion by hormones such as endocrine.

① Unit animal

A unit animal is an animal with one stomach, which has a simple digestive tract structure, little cecal function, and a relatively small amount of microorganisms in the large intestine. The representative unit animal pig has the structure of 'esophagus, stomach, duodenum, ileum, appendix, colon, rectum'.

② Ruminant

The rumen is divided into four parts of the stomach, each functioning, cecum and large intestine is well developed. The rumen stomach accounts for 70 to 80% of the total digestive tract, and the above contents also account for the largest proportion of the total digestive organs.

The first rumen of the ruminant is crowded with the villi, and the second is the honeycomb shape of the stomach wall above the honeycomb. In the third place, the water is absorbed by the folding of the stomach wall over the umbilical cord, and the digestion of the fourth stomach occurs on the third over the corrugation. The digestive tract moves freely in the first to fourth digestion and digestion proceeds.

If you look at the function of each part, the rumen (first and second place) has huge microorganisms in it, and it is decomposed and synthesized by microorganisms. The third place has the function of letting the well-digested parcels pass to the fourth, and absorbs moisture and concentrates the parcels. In the fourth place, digestive juices and the like are secreted and function similar to that of the unit animal. The typical digestive organ of the ruminant is the structure of the esophagus, the rumen, the lump, the wrinkle, the duodenum, the ileum, the appendix, and the colon.

③ Algae

The digestive organs of avian chicken have the structure of 'esophagus → follicle → frontal → proximal → duodenal → ileal → appendicitis → total excretory field. Birds belong to a unitary animal, but have beak instead of lips and jaws, no teeth, and a tongue is keratinized.

The esophagus is relatively long and large in diameter, and it secretes a lot of mucus that lubricates the upper part of the esophagus, making it easy to swallow the feed. The follicle is a bag formed by the expansion of a part of the esophagus, which stores the feed temporarily and adds mucus to cause fermentation by some microorganisms. Seedlings occur in the same way as other animals, and they secrete both pepsinogen and hydrochloric acid. In the proximal region, the water content is low and the digestion by the enzyme is limited, but the digestion is finely crushed to facilitate the enzymatic action and digestion and absorption in the small intestine. In the duodenum, pancreatic juice and bile juice are secreted and most digestion occurs. Unlike mammals, algae have a paired cecum, the colon is relatively short and the distinction between colon and rectum is unclear.

Scientific research into the number and quantity (qualitative or quantitative requirements) of nutrients required to maximize animal production capacity and to maximize production efficiency has been intensified over the past century. In animal nutrition, nutrients are classified as carbohydrates, fats, proteins, minerals and vitamins.

① Carbohydrate

Carbohydrates are composed of carbon (C), hydrogen (H), and oxygen (O). (1), fructose (2 ~ 10), and polysaccharide (10 or more) depending on the number of sugars to be bound. . However, other monosaccharides, except for 6-carbon sugars, do not play a major role as nutrients ingested by animals.

② Fat

Fat is an organic compound, which is a substance that is not dissolved in water but dissolves in a fat solvent. It is composed of carbon (C), hydrogen (H) and oxygen (O). The ratio of carbon to hydrogen high. Fat is divided into fat (fat or oil) and wax. Fat and oil are glycerol and ester of fatty acid. At room temperature, fat is solid and oil is liquid. However, fat represents both. wax is an ester with alcohol. Fats play an important role as a source of energy, tissue-forming substances, hormones and fat-soluble vitamins and essential fatty acids in tissues of tissues in animals.

③ Protein

Protein is a complex organic substance of a polymer composed of amino acids. It is composed of carbon (C), hydrogen (H), and oxygen (O) such as carbohydrate and fat. It is the most important ingredient in the formation of animal tissues and is contained in all living cells. Proteins are classified as simple, complex, and inducible proteins.

④ Minerals

Minerals are small amounts, but they are contained in all body tissues and are one of the absolutely necessary nutrients. In general, the seven major elements required for animals are calcium, magnesium, potassium, sodium, phosphorus, sulfur, and chlorine. The other elements that have physiological functions are iron (Fe), cobalt (Co), copper (Cu) Mn, Zn, Mo, I, F and Se. It plays a role in controlling the equilibrium of bone, soft tissue, body fluid component and acid · base, and occupies 60 ~ 80% of total inorganic matter of animal.

⑤ Vitamins

Vitamins are classified as fat-soluble vitamins and water-soluble vitamins, depending on their solubility. The fat-soluble vitamins A, D, E, and K, and water-soluble vitamins B and C, etc. Vitamins can also have an effect on the animals due to deficiency and hyperactivity.

Verification tests (in vitro, in situ, and in vivo tests) based on nutrient content are conducted through three tests to find out how the nutritional content of animal feeds actually apply to animals.

① In vitro test

It is a test to investigate indirectly how digestion occurs by creating an environment similar to an animal digestive organ artificially in a laboratory. This method is used when animals can not be used directly, but it can be easily tested in a short period of time, but accuracy is low.

② in situ test

It is a test in which a certain amount of crushed animal feed is put into a nylon bag and directly administered to the digestive organ of an animal to measure the digestibility of animal feed after a certain period of time.

③ In vivo test

Animal feeds are fed directly to animals. By feeding them for a certain period of time, the metabolism of digestion, absorption, utilization and excretion of nutrients is analyzed by analyzing the palatability, amount of feed, body weight gain, digestibility, It is a test to measure. These three tests can directly or indirectly investigate the effect of animal feed.

 Unit Animal nutrition is a discipline that deals with animal nutrition in pigs, chickens, and dogs with only one stomach. The development of this discipline is closely related to humans. In the past, individuals with high endogenous values for farming life have been preferred, and as industrialization and development have progressed, they have developed into food production aspects. In addition, the object of study is animal, but it is applied to various studies on human health, and child food formula is also a product developed based on various animal experiments.

Ruminant nutrition is a discipline that deals with the nutrition of ruminants. A ruminant refers to an animal with four stomachs, which has physiological characteristics such as swallowing the ingested feed and then releasing it again. Unlike humans and other unit animals, pigs and chickens, they have a structure that digests nutrients through microbes in the rumen (first place). In other words, it is a study of how rumen digestive physiology affects ruminants.

The development of this discipline has also been closely related to humans and has evolved into milk production of dairy cows and meat production, meat quality, and food production. Ruminants account for 35-40% of the world's aquatic production and 100% for milk. Thus, the development of the study is proceeding toward studying the digestive physiology of the ingested feed to produce higher production capacity or high efficiency through low cost feed.

Starch is an important storage material that is widely distributed in most plants. Starch is a long chain carbohydrate that is stained with a potassium iodide solution in black blue and appears as a starch phase on the indenter. The starch in the chloroplast first made by photosynthesis is called assimilation starch and the starch stored in the storage organ is called the reserve starch. And, when the assimilated starch or stored starch is transferred to another tissue, it can be stored temporarily during the movement, which is called a transitory starch.

The starch used by a person is all stored starch, and potato tuber, sweet potato root, seed, and fruit are professional storage organisms and store unheated starch.

Resistant starch means that some of the starch ingested is not digested, which is called resistant starch (RS). The reason for not being digested is as follows: First, amylase does not work when grain is partially processed, such as brown rice, or when it exists as small grain. Second, enzyme activity is impossible when starch is not partially hydrolyzed. The starch structure becomes gelatinous during the aging process and the efficiency of the digestive enzymes decreases or becomes impossible. As such, starch that is not digested in the digestive system acts like dietary fiber, and fermentation takes place by bacteria in the large intestine. The amount of the resistant starch contained in the food is affected by the source, the degree of aging, the degree of grinding, the degree of grinding of the kernel, the processing process, the cooking and storage method, The importance of resistant starch acts like dietary fiber, so diabetes. Obesity and coronary artery disease, and 1 g of resistant starch can be used as a weight loss agent because it gives about 2.15 ~ 2.34 kcal of calories.

Resistant starch (RS) is classified into four types. RS1 means a starch which is difficult to meet the enzyme, RS2 means a raw starch having a crystal form of B-type such as potato, banana starch and high amylose corn starch, and since the resistance to the enzyme is lost when heated, It is a form that can not be used for foods to be heated such as processed foods. For example, a method for increasing the R2 content is disclosed in Korean Patent Publication No. 2004-0065072. Korean Patent Laid-Open Publication No. 2004-0065072 discloses that the RS content can be increased by adding acid treatment and heat treatment to starch in preparing crosslinked starch. RS3, on the other hand, is the starch aged by heating. The higher the amylose content, the higher the RS yield. Currently, the US and Europe are producing Novelose 330 and Crystalean, which are branched from starch and subjected to heating and cooling processes. They do not maintain the same shape as raw starch particles, and some become amorphous by heating, The absorption rate is increased compared to the live mass. Once the absorbed RS3 starch has no further volume increase by heating, it can have a stable structure during cooking and processing. Starch, made by chemical modification, is also resistant to enzymes, called RS4. RS4 exhibits a particle shape such as a viable powder by crosslinking, and the swelling power can be different depending on the production method. RS4 type starches can be prepared by chemical treatments such as cross-linking, esterification, etherification and lintnerization, and cross-linking RS4 starch, which is a chemical modified starch, has been known. For example, in Korean Patent Publication No. 2002-0070671, crosslinked resistive starch having an RS4 form in which a raw starch powder is annealed and a surfactant is added to increase the yield of resistant starch and to facilitate crushing is disclosed.

Therefore, the inventor of the present invention has developed a rice for food which can improve the content of resistant starch which can be used in companion animals.

In addition, when rabbits prepared according to the present invention are used for preparing companion animal feeds, it helps to solve the problem of obesity in animals and can contribute to the prevention and treatment of diabetes in the rapidly increasing companion animal. This is because the resistant starch reduces blood sugar and makes it possible to produce low calorie feeds. It also has the effect of enhancing the taste and flavor of feed for companion animals.

Hereinafter, the present invention will be described in detail. Prior to this, terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary terms, and the inventor should appropriately interpret the concepts of the terms appropriately It should be interpreted in accordance with the meaning and concept consistent with the technical idea of the present invention based on the principle that it can be defined. Therefore, the constitutions described in the embodiments described herein are merely the most preferred embodiments of the present invention, and are not intended to represent all of the technical ideas of the present invention. Therefore, various equivalents which can be substituted at the time of application It should be understood that variations can be made.

A method for producing rice with improved resistance starch content according to the present invention comprises:

Preparing a coating solution composed of Lentinan, Erithadenine, and Ergosterin;

Laser treating the coating solution; And

Coating the surface of the rice with the coating solution, and coating the rice and the coating solution at a weight ratio of 1: 0.05 to 0.3.

Hereinafter, a method for producing resistance starch-enhanced rice applicable to feed for companion animals of the present invention will be described in detail.

First, prepare a coating solution consisting of Lentinan, Erithadenine and Ergosterin.

Here, the lentinan is a polysaccharide having an antitumor action contained in shiitake mushrooms. This polysaccharide has branches by 1,6 bonds in β- (1 → 3) -glucan. The antitumor effect of lentinan is known to inhibit the proliferation of cancer cells by enhancing the immune function of the living body rather than directly acting on the cancer cells.

It has a molecular weight of about 400,000. Nonlinearity [α] D + 19.5 ° + 21.5 ° Polysaccharide isolated from Lentinus edodes. It is a white powder that does not dissolve well in water but is soluble in alkali. The basic structure is to have two [beta] -1,6-glucopyranoside branches for five glucose residues of the straight chain carrying a [beta] -1,3-glucopyranoside bond.

The action of T cell enhancer, activation of macrophages, inactivation of complement component 3, and activation of complement second pathway (propperidine group) are known, and there is also a host reperfusion antitumor activity, Retention, survival for autologous cancer, and inhibition of chemical carcinogenesis. In addition, resistance enhancement against parasites such as Japanese schistosomes is also known. Β-1,3-glucan (average degree of polymerization DP of about 200) called pachyman, which is positive for such antigens, is also present in sclerotia of Poria cocos, but it is highly positive for antinuclear cells except for the side chain containing a small amount.

Erythadenine is an effective ingredient extracted from mycelium of shiitake mushroom and is effective for blood pressure lowering and diabetes. It is a kind of amino acid and has been reported to be effective in blood pressure lowering because it promotes blood circulation and acts to lower cholesterol and adrenalin. In particular, it lowers cholesterol in blood, facilitates insulin secretion in the pancreas, and facilitates blood glucose control. It is also good for essential hypertension because it regulates the metabolism of corticosteroid hormone, corticosteroid, to inhibit the penetration of cholesterol into the inner wall of the blood vessel and to promote the metabolism of cholesterol and to gradually release it. It is also reported to be effective for kidney disease and gallstones.

2 (R), 3 (R) -Dihydroxy-4- (9-a-dyl) -butanoic acid. It is also called plasma cholesterol lowering substance separated from shiitake mushroom, lenticin, lentinacin. Most of the ingested eritadenin is not absorbed, but slightly absorbed, it inhibits the formation of lipoproteins in the liver, liver, and reduces the plasma cholesterol and excretion of the neutral sterol into the feces. Dried shiitake mushroom is about 60 ~ 80mg for 100g, and green mushroom contains about 1/10 of it.

Ergosterin is extracted from yeast, mushrooms (such as shiitake mushrooms), and fungi. Is a cyclic pentanophenanthrene nucleus having a cyclic structure of higher monohydric alcohols. It is a colorless crystal that dissolves in chloroform, benzene, does not dissolve in alcohol, ether and does not dissolve in water. Animal, higher plants contain cholesterol and a small amount of vitamin D is converted to vitamin D by the irradiation of the provitamin D is. It is clinically used as an anti-infective vitamin. Needle crystals (recrystallized from 99% acetone), leaf crystals (recrystallized from ethanol). The melting point is 166 to 167 °. It dissolves well in ether, chloroform and pyridine. 52 volumes of cold ethanol, 36 volumes of hot ethanol, 200 volumes of cold acetone, 32 volumes of hot acetone, and 28 volumes of boiling ether. It is dissolved in hexane and acetic acid.

   [Table 1] shows the composition ratio of the mixed composition for " production of resistance starch-strengthened rice usable for companion animal feeds " composed of the above-mentioned substances.

The composition ratio of the mixed composition for " the production of resistance starch-reinforced rice usable for companion animal feed " division Material name Composition ratio Remarks mix
Composition Lentinan 30wt% Error rate% Erithadenine 30wt% Error rate% Ergosterin 40wt% Error rate%

       The above composition ratio is a result of finding the most suitable golden ratio through repeated experiment.

Next, the coating solution prepared above is irradiated with a laser.

Here, it is preferable that the laser beam has a wavelength of 1,020 to 1,028 nm, a frequency of 5.5 to 5.8 Hz, and an average output optical power of 82 to 85 W. When the laser is irradiated within the range described above, the cohesive force of the coating liquid becomes higher due to the supermagnetic nanoparticle properties, so that the coating efficiency is improved when coating the feed rice. Further, when the coating solution for laser irradiation is coated on the surface of the rice for feed, it has an advantage that it can be maintained without surface separation for 3 to 6 months.

The laser irradiation is preferably conducted for 3 minutes to 5 minutes.

The laser-irradiated coating solution may be mixed with water in a dispersion solvent, and the coating solution and water are preferably mixed at a weight ratio of 500 to 1,000: 1. When the content of the coating liquid is less than the content described above, it can not affect the effect of the resistant starch. If the content of the coating liquid exceeds the content described above, it is precipitated in the solvent, It is difficult to evenly coat the surface of the substrate.

Next, the previously prepared coating solution is coated on the surface of rice to obtain rice for feed having enhanced resistance to starch content.

Here, the rice for food to be coated can be cleaned in advance by washing treatment. Before coating, the rice is preferably dried at 50 to 80 DEG C and dried to have a water content of 15 to 25%. In this case, drying is preferably carried out by natural drying or hot air drying.

Then, the coating liquid is coated on the surface of the prepared rice. Examples of the coating method include a method of immersing or spraying rice in the coating solution.

Here, the rice and the coating liquid are preferably coated at a weight ratio of 1: 0.05 to 0.3, and most preferably 1: 0.05 to 0.25. When coated at the weight ratio described above, it can be uniformly coated on the surface of rice and maximize the content of resistant starch.

When the coating liquid is coated on the surface of rice for feed, it can be coated more than once.

For example, 0.05 part by weight of the coating liquid may be coated once on the surface of the rice, and 0.05 part by weight of the coating liquid may be further coated on the surface of the rice once more.

When the coating is completed, the coated rice may further be dried to have a water content of 15 to 18%.

The rice for rice produced in the present invention can be cooked in the following manner to enhance the content of resistant starch.

Generally, when rice is cooked, a temperature of 100 ° C or more is applied to rice. At this time, the amylose in the starch contained in the rice and the coating solution are hydrogen bonded, and the hydrogen bond in the amylose is reformed to change the bonding angle. The existing amylose hydrogen bonding angle is 104.2 degrees, but the hydrogen bonding angle through the reforming of the hydrogen bonding is 104.5 degrees. Therefore, since it resists amylase that decomposes starch, starch is not decomposed into glucose, but is discharged to the outside of the body as it is.

When the feedstuff for companion animals is prepared by using the resistant starch-reinforced rice according to the present invention, the amount of glucose absorbed into the body of the companion animal is reduced, the blood sugar level is decreased, and the calorie absorbed is reduced, .

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The scope of protection of the present invention should be construed according to the following claims, and all technical ideas within the scope of equivalents should be construed as falling within the scope of the present invention.

Hereinafter, the present invention will be described in more detail with reference to Examples. It is to be understood by those skilled in the art that these embodiments are only for describing the present invention in more detail and that the scope of the present invention is not limited by these embodiments in accordance with the gist of the present invention .

Example 1.

30 wt% of lentinan, 30 wt% of erithadenine and 40 wt% of ergosterin were mixed to prepare a mixture. Here, the average particle diameter of the mixed composition was 80 nanometers for Lentinan and Erithadenine, and 120 nanometers for Ergosterin.

Subsequently, silicon paper having a thickness of 0.3 mm and a diameter of 30 cm was prepared. The silicon paper used in the examples was prepared by cutting a thin single crystal silicon having a purity of 99.9999999% and smoothening the surface. Then, the mixture prepared on the silicone paper was applied to 0.2 mm. Silicon paper coated with the mixture was irradiated with a laser having a wavelength of 1,020 nm, a frequency of 5.5 Hz and an average output power of 82 W for 3 minutes.

Then, the water and the mixture were mixed at a weight ratio of 1,000: 1, and then the mixture was added to a stirrer and stirred at 500 RPM for 3 minutes to prepare a coating solution of rice.

The preliminarily cleaned white rice was dried at 65 ° C. and prepared to have a moisture content of 20%. The rice and the coating solution were adjusted to a weight ratio of 1: 0.05 and sprayed first on the surface of the rice, The surface of the coating solution was adjusted to a weight ratio of 0.05, followed by second spraying. The second spray - coated rice was dried at 80 ℃ to a water content of 15% to prepare rice.

Lastly, 200g of the above-prepared feed rice was put into a general rice cooker to cook rice.
