Study on Methods of Rapeseed Polysaccharides (RP) by Ultrasonic Extraction

Abstract

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.

Key words: rapeseed polysaccharides, ultrasonic extraction, extractive technique
