摘要
本文采用高压电脉冲提取方法,从米糠中提取多糖。用苯酚-硫酸比色法测定米糠多糖含量。初步探讨了影响米糠多糖得率的影响因素(脉冲数、电场强度、料水比)和高压电脉冲的作用机理。用正交设计实验优化高压电脉冲提取米糠多糖的提取条件:脉冲数为12,电场强度为45kV/cm,料水比为1∶20。
The attempt of this study is to extract rice bran polysaccharide by using high electric field pulse. The content of rice bran polysaccharide was determined by phenol - vitriol colorimetry. The main extracting condition factors （number of pulse, electric field intensity, and water/rice bran ratio） were by orthogonal experiments, The result shows that the optimum extracting condition as follow：pulse number 12, electric field intensity 45kV/cm , and water - rice bran rate 1：20.
