Abstract:
Objective: To definite the technological parameter of carboxymethylation modified product of Poria cocos, improve the water-soluble ability of Poria cocos and to expand the processing applications of P. cocos in Chinese medicine industry. Methods: Taking the P. cocos powder as raw materials, The single-factor experiment of carboxymethylated modification was carried out to gain the greatest degree of substitution. Results: Reaction medium, 85% ethanol solution reaction temperature, 50°C, 6 h of etherification after 2 h of and molar ratio of alkali/acid controlled in 2.5 : 1-3 : 1, and the water-soluble ability was improved. Conclusion: Using ethanol as reaction medium and method of two steps of alkaline addition to obtain carboxymethylation modified product of P. cocos, the processing characteristics of modified product could be greatly improved and be used in processing applications.
