Abstract:

Soybean meal was used as the experimental subject to explore the extraction and purification of soluble soybean polysaccharides (SSPS). During the choice of enzyme, alkali protease exhibited the best enzymatic extraction efficiency among papain, alkali protease and complex protease. The optimal extraction conditions of SSPS were explored by evaluating the effects of extraction pH, extraction time, material-liquid ratio, enzyme addition amount and extraction temperature on extraction rate. Results indicated that the optimal extraction conditions were extraction pH of 6.0, extraction temperature of 50 ℃, extraction time of 1.5 h and material-liquid ratio of 1:20. Under these optimal extraction conditions, extraction rate of SSPS was up to 17.92 % and the purity of SSPS was 86.32%.

Key words: soluble soybean polysaccharides (SSPS), enzymatic extraction, purification
