Fermentation soybean flour combines modern bioengineering fermentation bacteria technology with Chinese traditional solid fermentation technology, using soybean flour as the main raw materials, vaccinating microbes, through microbial fermentation, eliminating as possible the anti-nutrient factors in soybean flour, effectively degrading soybean protein as a small peptide protein source, and can produce probiotics, oligpeptides, glutamate, lactic acid, vitamins, UGF (unknown growth factor) and other active substances.
