The paper studied the effects of enzymatic temperature,enzymatic time,enzyme amount and pH value on extraction rate and activities of expanded rice bran polysaccharide.

Because of its high bioactivity in anti-tumour, immunological enhancement, anti-bacterial infection and decreasing concentration of sugar in blood, the research of rice bran polysaccharide has been a hotspot.

The extracting means and applications of extractions that come from rice bran are summarized,the extractions include rice bran oil,rice bran protein,rice bran polysaccharide,rice bran phytin et al.

The effects ofalcoholconcentrationandsolutionpHonthe precipitatinproperty ofthe rice bran polysaccharides were also investig ated.

The experimental purpose is to study the hypoglycemic effect and liver antioxidation of rice bran polysaccharides on diabetic mice induced by streptozotocin(STZ).

Hot water-soluble crude polysaccharide (HWSRBP), cool water-soluble crude poly-saccharide (LWSRBP),Alkaline-soluble crude polysaccharide (ASRBP) and Alkaline-insoluble crude polysaccharide (AISRBP) were obtained from defatted rice bran.

The technology of extraction and separation of polysaccharide from rice bran was studied.

In order to understand the effects of rice bran polysaccharide(RBP) on modulating immune function,two hundred and fifty healthy male chickens were randomly divided into five groups,with 50 chickens per group.
