The invention provides a bamboo shoot extract containing compound amino acids and polysaccharides, a preparation method thereof, and a bamboo salt prepared therefrom. Obtain the bamboo shoot protein liquid after the bacillus fermentation, divide the bamboo shoot protein liquid into three parts, one part obtains the bamboo shoot fermentation koji material I through the fermentation of Aspergillus niger, one part obtains the bamboo shoot fermentation koji material II through the Bacillus subtilis fermentation, and the remaining one part is first mixed with the bamboo shoots Fermented koji material I and acid protease, mixed with bamboo shoot fermentation koji material II and alkaline protease after enzymolysis, the obtained enzymolyzed solution was subjected to enzyme inactivation, filtration, and decolorization, followed by micro-membrane filtration, ultra-membrane filtration and nano-membrane filtration to obtain Bamboo shoot extract. The invention combines the biological fermentation method and the enzymatic hydrolysis method to release amino acids and polysaccharides in the bamboo shoot protein to the greatest extent, has mild reaction, energy saving and environmental protection, high utilization rate of bamboo shoots, and can realize standardized production. |
