| 摘 要： | 【目的】研究利用果胶酶和纤维素酶酶解杏皮渣制备皮渣汁最佳工艺条件。【方法】采用单因素试验和正交试验,研究果胶酶用量、纤维素酶用量、酶解温度、酶解时间对杏皮渣出汁率、浸提汁可溶性固形物含量的影响。【结果】杏皮渣制汁的最佳条件是:果胶酶用量0.5%、纤维素酶用量2%、酶解温度49℃、酶解时间4h。出汁率为73.41%,比空白提高15.75%,可溶性固形物质量为22.88 g,比空白对照相比提高9.14 g。【结论】采用果胶酶和纤维素酶,能提高杏皮渣出汁率和可溶性固形物含量,改善杏皮渣制汁效果。

| Abstract: | 【Objective】The effects of pectinase and cellulase on the juice extraction rate of apricot dregs were studied to find out the optimum conditions of enzymatic hydrolysis.【Method】The effect of the quantity,enzymatic temperature and time of two enzymes on the juice extraction rate of dregs of apricot were studied by single factor and orthogonal design.【Result】 The optimum conditions of enzymatic hydrolysis were as follows: 0.5% pectase and 2% cellulase hydrolyzing for 4 h at 49℃.The juice extraction rate was 73.41%,which is 15.75% higher than controlled trial.The soluble solid was 22.88 g,which was 9.14 g heavier than controlled trial.【Conclusion】Two enzymes were better than the single enzyme for the juice extraction rates and the soluble solid of apricot dregs. |
