摘要: 研究了以大豆为原料,通过浸泡降解大豆细胞壁提取大豆蛋白生产豆腐的生产过程中,添加一定量的高科技生物技术产品“纤维素酶”,来提高浸泡大豆时的胀豆率和豆腐得率及风味的影响因素。结果表明:纤维素酶中所含有的纤维素酶和半纤维素酶在浸泡大豆时起到很好的降解大豆细胞壁的作用。最适宜的工艺条件是:纤维素酶用量为0.1%,30℃恒温浸泡6h,pH值控制在5~6之间。

关键词: 纤维素酶, 降解, 胀豆率, 豆腐得率

Abstract: The effects of utilizing some cellulase,a product being brought by high biological technology were investigated to increase the ratio of swelled beans and the yield of bean curd by steeping in water to degrade the cell walls and extract protein during the process of the production of bean curd .The tested results showed that cellulase and hemicellulase could well degrad of the cell walls when steeping the soybean in water.The most suitable condition was steeping the soybean with 0.1% cellulase at 28℃ during 6h.The pH range of 5~6 was generally suitable.
