Abstract:
The soluble soybean polysaccharide（SSPS）is a water-soluble polysaccharide extracted from the cotyledon of soybeans.It is a widely used natural functional ingredient with high biological activity.Extracting SSPS is one approach of the comprehensive utilization of bean dregs，a major by product from soybean processing.The SSPS was extracted in organic acid solution from bean dregs.After a series of single factor experiments，including the extraction pH，the kind of organic acid，the extraction temperature and time，the best process parameters were determined：extraction pH was 3.8，extraction media was tartaric acid aqueous solution，extraction temperature was 110℃，and extraction time was 1.5 h.Under that condition，the dissolution rate of protein was only 2.18%；the molecular weight of product，which consists of three parts，reached 5.424×105；and the yield of SSPS could reach 27.65%.
