鲜(冻)肉中挥发性盐基氮测定方法的改进研究
Improvement of the Method for Determination of Volatile Base Nitrogen in Fresh(Frozen)Meat
摘要
Abstract
[Objective]To improve the determination of volatile base nitrogen in fresh(frozen)meat samples.[Method]The volatile nitrogen in fresh(frozen)meat was determined by using the fux 8400 automatic nitrogen meter instead of the traditional national standard GB/T5009.44—2003(semi micro nitrogen method).The results of two methods were compared by the improvement of the method.[Result]The result of the im-proved automatic nitrogen determination method was not significantly different from that of the original national standard method,and the accuracy of the improved detection method was better than that of the original national standard method, and at the same time, the experimental error caused by manual titration was avoided.[Conclusion]The application of automatic nitrogen determination instrument had the advantages of simple operation,time saving and high efficiency.It was suitable for rapid detection of large quantities of samples.The improved method was worth pop-ularizing.关键词
