摘要: 通过单因素试验考察了果胶酶、纤维素酶、木瓜蛋白酶和中性蛋白酶对豆粕中可溶性大豆多糖提取效果的影响,并考察了两两组合及3种酶组合之后酶的最佳用量。结果表明:1.5%果胶酶和4.5%纤维素酶提取大豆多糖的得率最高,0.5%木瓜蛋白酶和3.0%中性蛋白酶去除蛋白的效果最好;将果胶酶分别与木瓜蛋白酶、中性蛋白酶以1.5∶0.5和1.5∶3.0的比例混合,纤维素酶分别与木瓜蛋白酶、中性蛋白酶以4.5∶0.5和4.5∶3.0的比例混合,得出两两组合酶中果胶酶与木瓜蛋白酶、中性蛋白酶在3.5%和1.0%用量下效果较佳;将纤维素酶与这两种组合酶分别以4.5∶3.5和 4.5∶1.0比例混合,得到纤维素酶与果胶酶和中性蛋白酶3种复合酶为最佳组合,用量为5.0%,多糖得率为24.21%,蛋白残留2.29%。此研究结果可为后续复合酶提取豆粕多糖的工艺研究提供了一定的理论依据。

Abstract: In this study, the effects of pectinase, cellulase, papain and neutral protease on the extraction of soluble soybean polysaccharide from bean curd were investigated by single factor method, and then the optimal amount of enzyme was investigated after the combination of two enzymes and three enzymes. The results showed that 1.5% pectinase and 4.5% cellulase had the best effect on soybean polysaccharide extraction, and 0.5% papain and 3.0% neutral protease had the best effect on protein removal. The ratio of pectinase and papain was 1.5∶0.5, and the ratio of pectinase and neutral protease was 1.5∶3.0. The mixture of cellulase and papain was 4.5∶0.5, and that of cellulase and neutral protease was 4.5∶3.0. The results showed that the effect of pectinase and papain was better at the dosage of 3.5%, and that of pectinase and neutral protease was 1.0%. The cellulase was mixed with the above composite enzyme at the ratio of 4.5∶3.5 and 4.5∶1.0, respectively. The results showed that complex enzyme of cellulase, pectinase and neutral protease was the best, the dosage was 5.0%, the polysaccharide yield was 24.21%, and the protein residue was 2.29%. The optimal amount of complex enzyme will provide a theoretical basis for the subsequent extraction of soybean meal polysaccharide by complex enzyme.
