Description

Cultivation method of germinated grains. {Omitted}

In the present invention, the grains are mixed and immersed in the nutrient solution extracted from the salt, herbal medicines, mushrooms, etc. having functional ingredients in the germination of grains, and then forced to inject air into the germs, which makes it more hygienic with more unique flavors and functional ingredients. It is to make germinated grains.

Currently, the manufacturing technology of germinated grains is classified into strengthening germination technology and functionality centered on brown rice. Among the germination techniques, there is no big difference in the technical method since germination is a natural phenomenon if real grains are a kind of seeds and only mainland and moisture are given under suitable conditions. Screening method using specific gravity, which is a method of selecting excellent seeds in the germination process, and germination conditions for soaking and adjusting humidity or temperature in germination chamber or germination box are usually 10 ~ 30 ℃ for more than 24 hours and hot air and hot air drying after dehydration. Also classified as a general method for mass production. In this germination method, producers' problems are related to microbial contamination during germination, and colonization of molds and yeasts may occur during germination. On the other hand, the method of applying the pine needle extract liquid after germination of brown rice by the technology to prevent the decay or enhance the function by using ocher water as a germination liquid with several technologies that are applied. Interesting applications are also emerging, including how to dissolve red ginseng powder and use it as planting water.

Technical problem of the present invention is divided into the following three.

1) Prevention of contamination during grain germination

In the germination of grains, soaking the grains in water and soaking them in the germination chamber to replenish moisture and germinating grains is a problem in mass production because they are easily exposed to the contamination of bacteria such as mold and yeast. have. To this end, in the present invention, since the germination of the water in the aeration tank for supplying the selected air to the extract nutrient solution, the pollution was solved.

2) How to give extract nutrition to cereals

Cereals are rich in nutrients such as vitamins, minerals, enzymes, etc., but the method of adding other flavors or functional ingredients is currently sprayed with pine needle extract to germinated brown rice, or germinated brown rice from filtrate. In this case, some components may leak during the cleaning process of germinated brown rice. However, the present invention uses the transpiration or osmotic pressure when grains germinate to deeply penetrate the inside of brown rice as a nutrient source for germination, thereby minimizing the outflow of functional components from such washings and relieving the grains from germination.

3) Scope of use of raw materials (grains) and extract nutrients

In the present invention, the extractable vegetable raw material, which is generally appearing as a functional material, can be used within the range set in the present study, and the target to absorb the extract nutrient liquid having the functionalities is not only the raw material used in the experiment, but also red beans, It can be widely applied to crude, sorghum and corn.

.

〈Manufacturing process of extract nutrient solution for germination〉

The first step is to create a germination nutrient solution that soaks cereals. In this process, the known hot water extraction method is most effective in terms of production and cost, and the effect is the same even if the prepared concentrate is diluted. The germination nutrient solution is required to extract the concentration under the condition of 1 to 30% so as to be suitable for germination. First, 1 to 30% of the purified water by converting the raw materials (leaf, mushroom, herbal medicine, etc.) to be extracted by weight ratio Then, the mixture was mixed with heat (92-100 ° C.) and extracted.

1) Preparation of extract nutrient solution using leaves

As a raw material for the nutrient solution, the leaves were used after being trimmed and washed. Brush, 칡 and ginkgo used only leaf part and stem in case of mulberry leaf. 1%, 5%, 10% in preliminary experiment. Extraction at 15%, 20%, 25%, 30%, 35%, and 40% weight ratios showed that the extraction yield and process control were best within the range of 1-15%. It was used for the germination experiment using the adjusted 8%.

2) Extraction nutrient solution using herbal medicine and mushrooms

Chinese herbal medicines used as raw materials purchased from medicinal herbs such as bokbunja, goji berry, ginseng, Astragalus, green tea, etc. 1%, 5%, 10%. Nine preliminary extraction experiments of 15%, 20%, 25%, 30%, 35%, and 40% were used as the basic concentrations of the experiments, with the median concentration of 1 to 15% being the most effective extract range. In the case of mushrooms, the same results were obtained by extracting the situation, ganoderma lucidum, agaricus, shiitake, oyster, etc. at the same concentration as described above.

〈Basic Process: Brown Rice Germination〉

No matter how good the extracted nutrient solution is, if germination does not occur, it is generally only absorbed nutrients into the grains. Therefore, growth experiments for each concentration of extract were preliminary, and in terms of both germination time and economic feasibility. . In addition, the extracted nutrient solution was mixed with each other to determine whether the degree of germination in common. As a result of germination test, the concentration of extracted nutrient solution was best at 1 ~ 15%, and germination was good at less than 10% in case of Ganoderma lucidum, Sigaria, Agaricus mushroom and Ginkgo leaf.

1) immersion of brown rice

The extracted nutrient solution was cooled to 35 ° C. or lower, and then the brown rice to germinate was immersed in the extract. The screening of brown rice traditionally uses the brine specific gravity method and the brown rice obtained by the general milling process. Brown rice was immersed in a mixture of extractive nutrient solution and immersion and germination temperature was 10 ~ 35 ℃. The extracted nutrient solution was about 2 to 10 times the amount of brown rice added (about twice the height of the injected brown rice layer), and the extracted nutrient solution was the 8% extract which is an extract ranging from 1 to 15%.

3) Bubble germination

The soaked brown rice was immediately aerated by blowing purified air from the bottom (Fig. 1). The forced air injection method, which is a feature of the present invention, not only inhibits the growth of mold, yeast, and the like, which are easily generated when germinating brown rice, but also provides oxygen required for germination of brown rice and prevents corruption of the extracted nutrient solution. Extracted nutrients are transferred to the inside of brown rice through the germination process and the liquid decreases so that the flow rate and concentration (soluble solids) are identified and new nutrients or purified water are supplied in the middle so as not to be insufficient. Germination tank temperature was raised to 35 ℃ in the preliminary experiment under the condition of more than 10 ℃, but germination and altered microbial growth of the extracted nutrient solution was not observed. Germination time was 8-96 hours and about 48 hours were required for germination shoot growth of 1mm.

4) drying and processing

If germinated shoots grow to 1 mm or the size required for product processing, stop germination and pick up brown rice. The dried brown rice goes through the process of disinfectant disinfectant treatment, washing, and drying to improve the commerciality before drying.The drying conditions may cause problems of cracking and color of germinated brown rice, so it is recommended to use hot air dryer at low temperature (25 ~ 60 ℃). To dry. The produced germinated brown rice becomes functional germinated brown rice with the advantage that the components penetrated inside are not easily leaked even after washing again, and it is packaged as it is or pulverized and processed into a powder form and commercialized.

<Example 1>

1. Preparation of materials

(1) Brown rice used in the material test was domestically produced in 2002, and was purchased from Gyeonggi Grain Distribution with the trade name "Golden Field".

② Pine needles, mulberry leaves and stems, ginkgo leaves, and sesame leaves were used domestically as raw materials. However, in the processing, it was easy to extract hot water through washing and cutting.

③ As extract raw materials, Chinese herbal medicines were purchased from ginseng, Astragalus, Cornus, Bokbunja, Schisandra chinensis and Goji medicinal herbs.

④ Mushroom extracts were purchased from Ganoderma lucidum, Sichuan, Agaricus, Shiitake and Pleurotus at the herbal medicine store and large retail store.

2.Hot water extraction

The prepared material was mixed with a ratio of 8 g of water to a ratio of 8 g of water (8%) for 30 minutes at 92-100 ° C., and then filtered through a filter paper (Advantec 110 mm: 100 Circles), and the extract was used.

3. Germination of Brown Rice

Brown rice was immersed in the extract by using 1/3 of the extract amount, and purified air was supplied to the bottom using an electric air blower. The temperature was maintained at 25 ° C. in the incubator and germinated. Germination time was until the germination shoots of brown rice grew by 1-2mm.

4. Result Analysis Method

1) Germination rate

Germination rate is a measure of the degree of germination of brown rice in extract nutrient solution. Here, random germination of 10 grams of brown rice after germination was calculated as the ratio of the germination shoots grown by 1-2 mm and the ungrown.

2) flavor experiment

Sensory tests were performed to determine the degree of absorption of the extracted nutrients in the germinated brown rice. First of all, the samples are dried after washing with water at least two times to prevent the detection of taste caused by the extracted nutrient solution. Does the questionnaire taste pine needles from germinated brown rice? Or does it taste mushrooms? If the taste is strong, etc., 5 points are considered as 1 point. As a control sample, three experiments were performed for each of the flavors compared with the brown rice germinated in ordinary purified water, and the results were summed and averaged.

3) microbial experiment (yeast and filamentous bacteria)

For the microbial experiment, potato dextrose agar medium was used, and 1 ml of the test solution was aseptically applied to a sterile petri dish and cultured at 25 ° C. for 5 days to measure the number of colonies generated. In this experiment, it was immersed without aeration as a control and placed in a germination box and left to stand. When germination buds grew more than 1 mm, treated with sterile water and 1 ml of the treated solution was taken.

5 results

1) leaves

2) Herbal Medicines

3) Mushrooms

* The germination rate is less than 100% due to the use of ordinary brown rice.
