菠萝中蛋白酶及其他组份在品种间的差异分析

Variation and Correlation of Bromelain and Other Component among Different Pineapple Varieties

以湛江地区6个主要菠萝品种巴厘、卡因、台农17号、台农16号、粤脆、香水为对象,研究菠萝的组分在品种间的差异及其与菠萝蛋白酶的产率和酶活力之间的相关性,结果显示,不同的菠萝品种间,各组分的含量以及蛋白酶的得率及酶活有显著差异。菠萝果皮和果肉的不同生长部位的蛋白含量、酶活力及酶得率有显著差异。酶得率与蛋白及纤维素含量呈显著正相关;酶活力与糖酸比、得汁率、纤维素含量及Zn含量呈显著负相关,蛋白含量、纤维素含量、糖酸比、得汁率是衡量菠萝产酶品质的重要指标。

Six varieties of pineapple in Zhanjiang zone named Bali,Kayin,Tainong 17,Tainong 16,Yuecui,and Xiangshui were chosen,to study the difference on the component and the output and activity of the bromelain,and correlation among them as well.The results showed that the content of each component,the output of bromelain and the activity of bromelain were effected obviously by the varieties and the different parts of pineapple（skin and flesh）.The output of the bromelain was positively correlated with the contents of protein and cellulose.The activity of the bromelain was negatively correlated with the ratio of sugar to acid,output of juice,and the content of cellulose and Zn.The content of protein,cellulose,the ratio of sugar to acid and the output of the juice were important traits of the bromelain properties.
