- 摘要:
- 以豆渣为原料,采用有机酸水溶液提取SSPS。通过对提取pH、有机酸种类、提取温度和提取时间的单因素试验,得到最佳的工艺条件:酒石酸水溶液作为提取介质,温度110℃,提取时间1.5 h,pH3.8。该工艺的蛋白质溶出率仅为2.18%,产品分子量由三部分组成,其中5.424×105为主要部分。水溶性大豆多糖得率达到27.65%。
- 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%.
