摘要: 对香蕉皮的水解工艺进行了初步研究,采用了稀硫酸水解法和经过稀氨水预处理后的酶水解法,并得到了两种水解工艺的最佳条件:稀硫酸水解法为110℃、1%的硫酸体积分数下反应2 h,总还原糖得率24%左右;酶水解法为:在3%的稀氨水浸泡48 h后,在pH值4.8、45℃、底物浓度4%、酶量1%下反应24 h,总还原糖得率19%左右。

Abstract: The hydrolysis process of banana peel was preliminarily studied. Two different ways such as hydrolysis by sulfuric acid and hydrolysis by enzyme were analyzed. The optimal reaction conditions were: hydrolysis by sulfuric acid at 110℃, 1% concentration and 2 h, the total reducing sugar yield was about 24%; hydrolysis by enzyme at pH value 4.8, 45℃, 4% substrate concentration and 1% enzyme concentration, for 24 h after 48 h soaking in 3% dilute ammonia, the total reducing sugar yield was about 19%.

Key words: banana peel, hydrolysis, cellulose
