Research on the Extraction Techniques of Wheat Bran’ Polysaccharide

Using the wheat bran as the material,some influential factors such as extraction time,temperature and the rate of wheat bran to water were studied while extraction of wheat bran’s polysaccharides with hot water.The orthogonal experiment based on those parameters illustrated the optimum extraction condition was bran/water ratio 1:20,extraction time 4 h,temperature 100 ℃.
