The continuous separation technology of dietary fiber and its components from soybean
摘要
Abstract
The continuous separation technology of dietary fiber and its components from soybean was studied in this paper. Results showed that the optimum conditions for extracting dietary fiber from soybean by chemical-enzyme method were papain 0.012g/g, pH12.03,temperature 68~C. Under this condition,the contents of TDF,SDF and IDF were 95.57% ,17.44% and 78.13% ,respectively. Hemicellulose was separated by alkali extraction and acid precipitation. The better condition were liquid-solid ratio 21:1,35.5℃ ,and extraction time 5.3h,the yield rate and purity of hemicellulose were 30.15% and 92.34%,respectively. The optimum conditions for separation of cellulose from dietary fiber by acidic sodium hypochlorite were concentration of sodium hypochlorite 16%,pH4.0~4.5,and temperature 65%. The yield rate and content of cellulose were 37.24% and 91.14%, respectively.关键词
