Embodiment 1
[0046] A preparation method for fermentation of soybean milk by Cordyceps militaris, comprising the following steps:
[0047] S1, activating the strain of Cordyceps militaris to obtain the activated strain;
[0048]The specific steps are as follows: inoculate Cordyceps militaris on the SDAY slant medium, put it into a constant temperature incubator, set the culture temperature at 22°C, and cultivate for 7 days, until the slant is covered with white hyphae, and yellow basal bacteria appear on the back of the slant The silk is mature, and the activated strain is obtained.
[0049] S2, inoculate the activated strain obtained in S1 into a 500mL Erlenmeyer flask containing 200mL of SDAY liquid medium, and culture it on a shaker at 22°C and 150r / min for 5 days. A large number of white mycelium balls are formed in the Erlenmeyer flask, and the liquid medium becomes clear to obtain the Cordyceps militaris seed liquid;
[0050] S3, inoculation: Soak and sterilize dry soybeans to obta...
Embodiment 2
[0055] A preparation method for fermentation of soybean milk by Cordyceps militaris, comprising the following steps:
[0056] S1, activating the strain of Cordyceps militaris to obtain the activated strain;
[0057] The specific steps are as follows: Inoculate Cordyceps militaris on the SDAY slant medium, put it into a constant temperature incubator, set the culture temperature at 22°C, and cultivate for 10 days, until the slant is covered with white hyphae, and yellow basal bacteria appear on the back of the slant The silk is mature, and the activated strain is obtained.
[0058] S2, inoculate the activated strain obtained in S1 into a 500mL Erlenmeyer flask containing 200mL SDAY liquid medium, and cultivate it on a shaker at 22°C and 150r / min for 3 days, a large number of white mycelium balls will form in the Erlenmeyer flask, and the liquid medium will become clear to obtain the Cordyceps militaris seed liquid;
[0059] S3, inoculation: Soak and sterilize dry soybeans to ...
Embodiment 3
[0064] A method for making soybean milk fermented by Cordyceps militaris, the operation is basically the same as that of Example 1, the difference is that the specific steps of sterilization after soaking soybeans in S3 are as follows: sterilize soybeans by high-pressure steam at 121 ° C for 30 minutes, cool to obtain sterilized Sterilize soybeans, put sterilized soybeans into shallow pans with a thickness of 2-3cm, then insert the Cordyceps militaris seed solution into the sterilized soybeans, and the inoculum amount is 100mL / kg of sterilized soybeans. In S4, the particle size of the soybean milk is 5 μm.
[0065] In order to verify the effect of the present invention, we have carried out a comparative experiment, and scored the soymilk sensory of different experimental groups, and measured the content of active substances.
