果胶酶催化条件探索及澄清果汁的研究
Studies on the Catalytic Conditions of the Clearence of Fruit Juice with Pectinase
【摘要】 测定了黑曲霉JB513果胶酶催化果汁澄清的最适条件.并对影响果汁澄清的其它因素进行了考察,结果表明,适量的明胶可使果汁澄清的时间缩短;纤维素酶有利于果汁的澄清;金属离子Ca2+,Mg2+对果胶酶有激活作用,Sn2+,Fe3+对果胶酶有抑制作用.
【Abstract】 The optimum condition for clearence of fruit juice catalyzed with pectinase prepared from A. Niger JB513 has been determined. We also found out that suitable amounts of gelatin can reduce the time of clearence, and the cellulase is useful to improve the clearence of juice. The pectinase can be activited by Ca2+ and Mg2+, and inhibited by Sn2+ and Fe3+.
