【摘要】 研究了酶法水解豆渣制备可溶性膳食纤维的工艺。在复合纤维素酶的添加量(与底物比值)为1·2%时,豆渣与水的比例为1g∶12mL。应用正交试验找出最佳水解条件,即pH为4·5,水解时间为12h,水解温度为40℃,豆渣与水的比例为1g∶12mL,在此条件下水解,可溶性膳食纤维的产率为39·03%。同时研究了以豆渣可溶性膳食纤维作为月见草油微胶囊粉末油脂壁材的可行性和效果。更多还原

【Abstract】 The technological process of enzymatic hydrolysis preparation of soluble dietary fiber from soybean residue was studied. When the concentration of Viscozyme L was 1.2%(enzyme-substrate ratio), the effect of pH, reaction time, temperature and substrate concentration on hydrolysis process were studied. The optimum hydrolysis conditions were determined by orthogonal design test. When pH was 4.5, the hydrolytic time was 12h , temperature was 40℃, the substrate concentration was 1∶12(soybean residue∶water), 39.03% of soluble dietary extraction was obtained. The feasibility and effect of soluble dietary fiber used as microencapsulating wall material of evening primrose powdery oil were also investigated.更多还原
