摘要
蛋白氮含量测定涉及到生产和科研的众多领域。目前常用的方法有凯氏定氮法、双缩脲法(Biuret)、紫外吸收法、考马斯亮蓝法(Bradford)。本文总结上述测定方法的基本原理和优缺点以及适用条件,针对这几种方法对非蛋白氮三聚氰胺检测的漏洞,提出三聚氰胺的几种科学测定方法。
The measurements of protein content involve production and researchment of numerous realm. At present, the familiar methods are Kjeldahl determination, Biuret ,ultraviolet absorption spectrometry？and Bradford. This test sums up the basic prineipie, merits ,drawbacks and apply conditions of the above methods. Aim at there are some leaks in these measurement methods of non- protein nitrogen（melamine）, bring forward some scientific measurement methods of melamine
