摘　　要：植酸酶可以提高单胃动物对饲料中植酸磷等物质的利用率，降低磷的排放量。通过定点突变、糖基化修饰、固定化和包衣等技术提高植酸酶产品耐热性，可以促进植酸酶在颗粒饲料中的广泛使用。同时也介绍了对植酸酶产品耐热性的合理评价方法。Phytase can increase the availability of organic phosphorus in feedstuff for single - stomach animal and reduce phosphorus discharge. By means of technology, such as targeted mutagenesis, glycosylation,immobilization, coating, all can expand application range of phytase in the pellet feed products. At the same time the evaluation on thermostability of phytase was introduced.

关 键 词：植酸酶 耐热性 评价方法
