Study on Extraction Technology of Polysaccharides from Jujube by Microwave Method

摘要

Jujube polysaccharide is one of the important natural active ingredients. In this paper, microwave extraction technology was utilized to extract jujube polysaccharide in different conditions using the yield as test index. The results showed that the optimum conditions were solid-liquid ratio 1:30, ultrasonic lasting time 25 min, temperature 50℃, which achieve the highest yield rate 5.38%.
