论豆粕质量鉴定方法

Discussion on Method of Evaluating Soybean Meal Quality

讨论了大豆粕蛋白及其营养成分与尿素酶活性存在的关系。对豆粕加热过度尿素酶活性无法检测 ,而蛋白溶解指数对生料和过熟可以测定。基于工厂豆粕品质管理的需要 ,我们推荐用尿素酶活性作为正常检测手段 ,用蛋白溶解指数作为仲裁。

This paper is discussed on the present relation of the soybean meal protein and nutritional ingredient and Urease activity,the Urease activity cannot measure the performance of overcooked soybean meal,and the protein solubility index can correctly measure the performance of overcooked and uncooked soybean meal.As the requirement of management for controlling soybean meal quality,we recommend that the urease activity can be used as normal measurement,and the protein solubility index should be used as final settlement.
