Description

Technical Field [0001] The present invention relates to insect-shaping rice with enhanced protein content and manufacturing method thereof,

More particularly, the present invention relates to a method of insect-insect for enhancing the protein content, and more particularly, to a method for insect-insect for insect use, which uses an insect as a supply source for reinforcing the protein content of rice, The present invention also relates to a method for producing insect microorganisms by increasing the protein content by combining an insect rich in protein with rice and a method for producing the insect microorganism.

Foods used as stocks throughout the world are diverse, but rice, which is a stock of Asian people in particular, is an important food resource globally. These rice varieties vary in variety and vary widely depending on the variety, but they mainly contain starch as a main component, contain about 7% protein, and contain less lipid, ash (ash) and vitamins . In addition, the protein of rice is mainly glutelin, it contains a small amount of albumin and globulin, and its amino acid composition is low in ricin, tryptophan, and methionine. However, it is protein 78, It is excellent.

In addition, in addition to general rice having the above-mentioned characteristics, in recent years, as the consumption preference for rice has become higher and diversified, the demand for rice and grain having health functions has been higher than that of rice having original function .

Accordingly, in order to meet such a demand, various kinds of rice reinforced with various functionalities and nutritional characteristics have been proposed and a manufacturing method thereof. For example, Korean Patent Laid-Open Publication No. 2006-0040535 (Patent Document 1) , Functional rice with the theme of rice processing with added dandelion juice, "Functional rice with the theme of processing by spraying mixed solution of dandelion stock <10b> 1157ml, alcohol 770ml on the basis of rice 80kg raw material" Korean Patent Laid-Open Publication No. 2007-0037556 (Patent Document 2) discloses a colostrum-containing colostrum-containing rice and a colostrum composition containing "colostrum-containing rice" and a colostrum composition containing "colostrum, cereal grains, Quot; as an essential component, "and Korean Patent Laid-Open Publication No. 2008-0073528 (Patent Document 3) describes a process for producing functional garlic, which comprises the steps of: mixing and pulverizing 0.5 to 1 part by weight of ethanol with respect to 100 parts by weight of garlic, separating only the liquid portion with a centrifuge, A step of preparing an extractive liquid for separating only the liquid portion by centrifugal separator from the selected one or more materials selected from olive oil, mulberry leaf, bokbunja, kelp, seaweed, aloe, carrot, sweet potato, broccoli and onion, Preparing a material solution through a mixing step of mixing 20 to 50 weight percent of the garlic raw solution and 30 to 50 weight ratio of the extract raw solution; washing the rice; washing the washed rice and the material solution into a stirrer, , A step of pressurizing the material solution and the rice mixture to infiltrate the material solution, and a step of drying at low temperature " Korean Patent Registration No. 10-1231253 (Patent Document 4) describes a method for producing a functional rice and a manufacturing apparatus thereof, wherein a rice bran and a microorganism preparation, which have not been tampered with, are added so that the water content of rice is 35 to 40 wt% The microbial agent is introduced into the flask and the temperature of the inside of the flask is maintained at 30 to 40 DEG C, and the flask and the microbial agent are stirred and cultivated while rotating the stirrer flask to cultivate the microorganism on the rice, , A treatment step of drying until reaching 18 wt%, and a pouring step of cultivating and drying the paddy rice.

However, the proposed method for the conventional functional rice including the above-mentioned patent documents mainly coating the surface of rice with a composition such as plants, and in particular, there is not proposed a method for supplementing low protein of rice .

On the other hand, insects have been proposed as a major source of food for human beings because they contain abundant proteins and can be mass-grown. As a basic research, researches on general components, amino acid composition, fatty acid composition, vitamins and minerals And basic nutrients have been studied, and simple cooking methods have been proposed. Particularly, as an invention proposed to use such insects as food materials, Korean Patent Laid-Open Publication No. 2016-0020626 (Patent Document 5) entitled " Method for producing feed powder for pets including insect powder and feed using the same, A pet food composition for a pet comprising insect powder, insect oil, non-toxic lacquer solution, and limonite, wherein the insect powder and insect oil comprise 0.5 to 10 parts by weight of insect powder and 0.05 to 10 parts by weight of insect oil, 0.2 part by weight of the insect powder, and the insect powder is a pulverized insect powder after extracting the insect oil, wherein the composition is selected from the group consisting of germinated barley flour, cordyceps, rice flour, roasted soybean flour, flaxseed, Starch, whey, and beef powder, "which discloses a pet food composition for pet, Patent Publication No. 2016-0135937 (Patent Document 6) discloses a feed composition containing a goat and an insect, and a method for promoting the growth of an animal and improving immunity using the composition, wherein the feed composition includes a goat and insect-containing feed additive Quot; animal feed composition for enhancing growth and improving immunity " As described above, research on the physico-chemical characteristics, processing aptitude as a food, and processing methods of insects of various kinds are still very limited.
