Abstract: Several extraction processes,such as traditional hot water extraction method,supersonic method and pulsed electric field(PEF)method,were used respectively to optimize the extraction process of defatted rice bran polysaccharide.The extraction rates of polysaccharide are 2.02%,2.87% and 2.59% respectively.The results showed that the latter two methods are simpler, more convenient and efficient than the former two.

Key words: defatted rice bran, polysaccharide, extraction, supersonic, pulsed electric field
