According to another preferred embodiment of the present invention, instead of boiled soybeans, the soy mushroom may be grown using rice, barley rice, yulmu rice, corn rice, sorghum rice or mixed grain rice.

According to another preferred embodiment of the present invention, the ratio of germinated mushrooms and beans in the harvest may vary, but is preferably 50:50, and the mushrooms may be Sichuan, Cordyceps, Ganoderma lucidum or Agaricus.

Thus the method according to the present invention is provided with mushrooms and beans or cereals, for example, predominantly rice, barley, yulmu, corn, sorghum or mixed cereals.

Hereinafter, the specific production method of the present invention will be described step by step with examples, the scope of the present invention is not limited to these examples.

Example 1 Culture of Strains

1. Preparation

The spawn according to the present invention is a soybean mushroom, which was deposited with the accession number KCPC 10597BP to the Biotechnology Research Institute Genetic Bank (KCTC), located at 52, Eeun-dong, Yuseong-gu, Daejeon, on February 13, 2004, for easy access by the general public. .

Since common seed spawn has low germ strength, it is subcultured to increase germ strength, and then cultured by transplanting it into the medium.

2. Preparation of Culture Medium

8 soybean mediums, such as soybeans, black beans, chestnuts, cheongtae, peas, kidney beans, spotted beans, and frosted, 1 kg each, washed and washed at 45 to 47 ° C., preferably 45 ° C. for 11 to 13 hours, preferably Was left to stand for 12 hours to allow pre-aging.

The fermented soybeans are collected, washed with purified water and sterilized at 100 ° C. for 3 to 5 minutes.

      The sterilized soybeans are collected in a tray as it is and left for 50 to 70 minutes at room temperature to drain the water. This leaves the sterilized beans in a smooth appearance.

In addition, barley rice, yulmu rice, corn rice, sorghum rice and mixed cereal grains in the same manner as above was used as a test medium, respectively.

3. Inoculation and culture

The medium was transferred to an ultraviolet clean room and inoculated at a rate of 0.1 to 0.5% (0.1 to 0.5 g / kg), preferably 2% (0.2 g / kg), with a strain of soybean mushroom spawn with a syringe sterilized and sterilized in a clean room after natural cooling. The mixture is then mixed uniformly, placed in a bottomed perforated container and germinated in the incubation chamber for about 24 to 36 hours until uniformly germinated.
