纤维素酶促进菠萝皮果胶提取的研究

为了促进菠萝皮中果胶的提取,对采用酸解法处理后的菠萝皮酸解液作进一步的纤维素酶酶解处理,且初步确定此工艺的最佳酶解条件：酶解温度为55℃,菠萝皮酸解液pH值为4.2,单位菠萝皮酸解液中纤维素酶用量为15.5 U·mL-1,酶解时间为140 min。在此工艺条件下,酶解液中果胶含量可达7.4 g·L-1,比菠萝皮酸解液中...

Extraction of Pectin from Pineapple Peel Promoted by Cellulase

In order to promote the extraction of pectin from pineapple peel,the acid hyclrolyzed suspending solution of pineapple peel was treated with cellulose,and the conditions of enzymatic hydrolysis process were screened.The results indicated that the optimal conditions were as follows： enzymatic hydrolysis temperature was 55℃;enzymatic hydrolysis pH volume was pH 4.2;appending quantity of cellulose was 15.5 U·mL-1;and enzymatic hydrolysis time was 140 min,and under these conditions,the concentration of pectin in the enzymatic hyclrolyzed solution reached 7.4 g·L-1,which was 40.7% higher than that of the acid hyclrolyzed solution.
