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。
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 %.
