无花果蛋白酶和果胶的综合提取

【摘要】 比较了无花果蛋白酶的两种提取方法，结果证明采用水抽提－鞣酸沉淀法优于有机溶剂法，前者得率为1‰，酶活为57U／g（均以鲜果计）。提取酶之后的果渣用水抽提－酒精沉淀法进行果胶的制备，能得到乳白色－淡黄色的果胶，得率为2％（以鲜果计）。并对不同成熟度的果实进行了研究，结果证明果实在5－7成熟时，有利于综合利用。更多还原

【Abstract】 Two methods for the extraction of ficin from ficus carical have been taken into account The results show that the water--tannic acid method is better than the organic solvent method. The yield of ficin of the former method is 1‰, the enzyme activity is 57U/g (weight of fresh fruit). By using the alcohol method, After the extrartion of enzyme, a light yellow pectin was obtained from the dregs of fruits, The yield of pection is 2% .The fruits of different maturity were studied and it was showed that the fruit at 50% ~ 70% degree of mature has the most favorable results.更多还原
