凯氏定氮法测定奶粉中蛋白质应注意的环节

凯氏定氮法作为测定蛋白质的经典方法在食品检测中应用很广,然而其操作过程相对复杂,但只要对其分析过程中的具体细节加以严格控制,就能提高分析结果的准确度,从而得到令人满意的结果。本文就奶粉检测过程中称量、消化、蒸馏及滴定等需注意的环节作了细致的分析和总结,望能为从事相关行业的人员提供一些有益的参考。

Kjeldahl determination determination of protein in milk powder should be paid attention to link

kjeldahl determination as a classical method for determination of protein in food testing application is very wide, however, its operation process relatively complex objective existence, but as long as the details under strictly control in the process of analysis, can enhance the accuracy of the results of the analysis, obtained satisfactory results. In this paper, the powdered milk test in the process of weighing, digestion, distillation and titration, ete should be pay attention to link has made the detailed analysis and summary, looking for personnel engaged in related industries to provide some useful reference.
