摘要: 本文采用超声提取法,从菜籽饼粕中提取多糖,用苯酚-硫酸比色法测定菜籽多糖含量。探讨了影响多糖提取率的主要因素(提取时间、料液比、次数),并用正交设计实验确定最佳提取工艺。结果表明:超声提取饼粕中多糖的最佳工艺为时间75min,料液比为1:40,次数为2,多糖产率为1.99%;超声法具有提取时间短、节省溶剂、提取率高的特点。

Abstract: Using ultrasonic extraction methods, RP was extracted from rapeseed-meal, and the content was determined by phenol-vitriol colorimetry. The main factors (extracted time, solid liquid ratio, times) were investigated, and finally the optimal extracting conditions were assured by orthogon:d experiments, while the content of RP was calculated. The results showed that: the optimal ultrasonic extracting conditions: 75min, 1:40,2 times and the content was 1.99%; Ultrasonic extraction was a better method for RP extraction with less time and solution, higher extraction rate.
