General description
果胶酶，又称为果胶裂解酶，主要存在于细菌、真菌和植物中。聚半乳糖醛酸酶是极为丰富的果胶裂解酶之一。果胶酶可用于果汁提取和澄清等广泛的生产应用。还可用于植物油提取、茶和咖啡发酵、纸漂白及用于家畜饲料添加剂、酒精饮料和食品行业中。

实验方案
在测定果胶酶活性时，使用了一种滴定终止反应法进行测定。在25 °C、pH 4.0条件下，一个单位的果胶酶每小时可从多聚半乳糖醛酸释放1 μmol 的半乳糖醛酸。
To measure pectinase activity, a titrimetric stop reaction assay is used. One unit of pectinase will liberate 1 μmol of galacturonic acid from poly-galacturonic acid per hour at pH 4.0 at 25 °C.
