Abstract

The invention discloses a preparation method of carboxymethyl pachyman, and particularly provides a method for fermentation preparation of carboxymethyl pachyman by regulating the variety and proportion of a carbon source and a nitrogen source in a Tuckahoe culture medium. Consisting of the processes of Tuckahoe strain activation, seed solution preparation, fermentation cultivation and carboxymethyl pachyman extraction, the preparation method is characterized in that in the process of fermentation cultivation, the fermentation culture medium comprises the following components by weight percentage: the carbon source (2.0%-4.5% of glucose, 0.1%-4.5% of carboxymethyl cellulose), the nitrogen source (0.45%-0.65% of yeast extract and 0.35%-0.55% of peptone), 0.1% of K2HPO4, 0.046% of KH2PO4, 0.05% of MgSO4.7H2O, and the balance water. The method provided in the invention can directly obtain carboxymethyl pachyman with certain degree of substitution and no chemical residue, and the carboxymethyl pachyman can be widely used in medicine, food and other fields.

Description

technical field

[0001] The invention relates to a preparation method of polysaccharides, in particular to a preparation method of carboxymethyl pachymane. Background technique

[0002] Poria cocos sclerotia is the main source of raw material for Poria cocos processing and utilization or extraction to prepare Poria cocos polysaccharide at present. But the production period of the Poria cocos sclerotia produced by the traditional Poria cocos cultivation method is long, the output is not high, and the consumption of pine wood is large. Producing Poria cocos mycelium with liquid culture technology, extracting active substances such as polysaccharides from Poria cocos mycelium and fermentation liquid can better solve the replacement problem of artificially planted Poria cocos, save a lot of wood, and contribute to my country's resources and biodiversity. Sexual protection is of great significance.

[0003] The traditional process of preparing carboxymethylpachyan (CMP) generally...
