摘　　要：液体酶后喷涂技术可以避免颗粒饲料热加工过程对酶活性的破坏。液体植酸酶是一种有机物溶液，在储存、运输和使用过程中的稳定性比较差，在一定环境条件下液体植酸酶会产生大量不溶性沉淀，导致植酸酶活性降低和后喷涂喷雾效果差，甚至堵塞后喷涂设备的管道和喷头。对液体植酸酶的静态和动态两种情况下的稳定性能的评价是判定其质量优劣的关键。Loss of liquid enzymes activity can be avoided by using Proportionate Dosing Post Pelleting Liquid Application （ PPLA ） after hot - working process of the particle feed. Liquid phytase is a kind of organic solution and it has poorer stability in storage, transport and using. In certain conditions, liquid phytase maybe emerge a large number of precipitation, leads to enzyme activity reduction and poor spraying, even blocking pipeline and nozzle of PPLA. The evaluation of both of static and dynamic stability performance of liquid phytase is the key to determine its quality.
