Yeast powder or yeast dipping powder is powdery yeast leachate, which is a biological culture medium product rich in protein, amino acids, peptides, polypeptides, nucleic acids, vitamins and trace elements, etc., made from high-protein baker's yeast or beer yeast as raw materials through autolysis, enzymolysis, concentration, drying and other processes. Product function: 1. Rich in protein, amino acids, polypeptides, nucleotides, B vitamins, growth factors, trace elements and other nutrients, coordinated in proportion, to provide comprehensive and balanced nutrition for microbial fermentation culture; 2. Meet the increasing requirements of the biological industry for organic nitrogen sources, and provide the necessary guarantee for the clean production of the fermentation industry. 3, fermentation industry field: can be used in new drugs, polypeptides, nucleotides, B vitamins, growth factors, trace elements and other nutritional components, proportional coordination, to provide comprehensive and balanced nutrition for microbial fermentation culture; 4, fermentation industry: can be used in pharmaceuticals, amino acids, organic acids, enzyme preparations, biological preservatives, biomaterials, vitamins, genetic engineering and other bioengineering industries.
