AI Technical Summary

Technical Problem

The existing technology for preparing water-soluble schizophyllum polysaccharide is complex, which is not conducive to industrialization, and it fails to effectively utilize the mycelial waste after schizophyllum fermentation.

Method used

Carboxymethyl schizophyllum polysaccharide was prepared by using fermented mycelium of Schizophyllum commune as raw material through pretreatment, low-temperature freezing and alkalization, eliminating the purification step. The low-temperature freezing technology was used to improve the contact efficiency between the alkali solution and the mycelium to carry out the carboxymethylation reaction.

Benefits of technology

The preparation process has been simplified, the degree of substitution of carboxymethyl schizopolysaccharide has been improved, and products with high transparency and moisturizing properties have been obtained, making them suitable for the cosmetics industry.
