ISO 16634-1:2008规定了测定油籽和动物饲料中总氮含量和计算粗蛋白质含量的方法。
这种方法和凯氏定氮法一样,不区分蛋白质氮和非蛋白质氮。对于蛋白质含量的计算,使用了各种转换因子。
本方法不适用于牛奶和奶制品。
ISO 16634-1:2008 specifies a method for the determination of the total nitrogen content and the calculation of crude protein content of oilseeds and animal feeding stuffs.
This method, like the Kjeldahl method, does not distinguish between protein nitrogen and non-protein nitrogen. For the calculation of protein content, various conversion factors are used.
This method is not applicable to milk and milk products.
