The invention discloses a rapid production method of
lactic acid bacteria fermented soya beans capable of dissolving fibrous
protein. According to the rapid production method, two-stage
solid-state
fermentation is adopted to produce functional fermented soya beans. The rapid production method comprises following steps: soybean is selected, and impurities are removed; soybean is immersed in
warm water at a ratio of 1:2-3 for 6 to 9h, wherein the temperature of the
warm water ranges from 25 to 30 DEG C;
steaming is carried out for 8 to 15min at 110 to 121 DEG C, after cooling, an obtained product is inoculated with 3 to 5% (V / W) of SYL-1
Bacillus subtilis;
fermentation is carried out for 42 to 54h at 26 to 32 DEG C so as to obtain a fermented soya beans semi-finished product, and the fermented soya beans semi-finished product is inoculated with 3 to 5%(V / W) of SYL-2
Lactobacillus brevis, is stirred to be uniform, and is subjected to
fermentation for 42 to 54h at 32 to 37 DEG C; after fermentation, an obtained product is subjected to 72h of post-fermentation in a refrigerator at 4 DEG C so as to obtain a finished product. According to the rapid production method, bioengineering technology is adopted; two-stage fermentation, including
bacillus subtilis primary fermentation and
lactic acid bacteria post-fermentation, is carried out via combination with traditional fermentation method;
flavor components such as fermented soya beans ester substances are increased; nutritional ingredients such as peptone, polypeptides, and amino acids are increased; functional ingredients such as douchi
fibrinolytic enzyme, oligosaccharides, organic acids, and
lactic acid bacteria are increased; the lactic acid bacteria fermented soya beans is capable of adjusting intestinal
flora balance, dissolving fibrous
protein, treating
constipation, preventing oxidation, and preventing cardiovascular diseases.
