摘要
目的:亚硝酸钠作为一种比较常见的食品添加剂,在食品工业中应用非常广泛,为了研究亚硝酸盐在腌制食品中的含量而进行了此实验。过程:研究选择6种常见的食品即梅菜、酸白菜、皮蛋、乡巴佬鸡蛋、腊肠和香肠,平均分为两组分别了采用高锰酸钾滴定法和分光光度计法对其的亚硝酸盐含量进行了测定。结果:通过研究发现,所选的6种食物亚硝酸盐含量分别为1、3、1、1、、5mg/kg。结论:6种腌制食品的亚硝酸盐均符合标准规定。
Objective： Sodium nitrite as a common food additive is widely used in the food industry.Nitrite content in pickled food was studied in this article. Procedure： six common foods of pickle mustard,fermented Chinese cabbage,preserved eggs,hillbilly eggs,salami and sausages were selected. The six foods were divided into two groups to measure its nitrite content by permanganate titration and spectrophotometer method. Result： the result showed that the nitrite content of the six foods was 1mg /kg,3mg /kg,1mg /kg,1mg /kg,2mg /kg and 5mg /kg,respectively. Conclusion： the nitrite content of the six pickled foods was according with the prescribed standards.
