Study of Optimization of Extraction Technology of Jujube Polysaccharides by Response Surface Methodology
摘要
Abstract
[ Objective ] The aim was to optimize the extraction conditions for the yield of polysaccharides from jujube residue which was collected after the extraction of rutin. [ Method ] The optimum extraction conditions for liquid-to-solid ratio, extraction time and temperature were studied according to the mathematics model built by using Box-Behnken central composite design and response surface methodology (RSM). [ Result ]The results showed that extraction conditions of jujube polysaccharides were liquid-to-solid ratio of 30: 1, extraction time of 3.6 h and temperature of 89 ℃, then the yield rate of jujube polysaccharides was 13.85％. [ Conclusion] The regression equation, which was obtained by multiple linear regression, accurately reflected the interrelation among the polysaccharides yield rate, liquid-to-solid ratio, time and temperature, and the optimum technology can be used to instruct the extraction of jujube polysaccharides.关键词
