摘　　要：目的:分析熟肉食品中亚硝酸盐含量变化,为食品安全提供帮助。方法:选取2022年1月至2022年12月采集到的200份熟肉食品,采用第二法分光光度法对亚硝酸盐含量进行测定,对比不同类型熟肉食品样品(卤肉食品、凉肉食品、烧烤肉食品)、不同来源熟肉食品(超市、农贸市场、流通商贩)、不同季节(春季、夏季、秋季、冬季)采集的熟肉食品样品亚硝酸盐含量、熟肉食品不合格率。结果:不同类型熟肉食品样品、不同来源熟肉食品、不同季节采集的熟肉食品样品亚硝酸盐含量以及熟肉食品不合格率间差异无统计学意义(P>0.05)。结论:本研究中采集到的熟肉食品中亚硝酸盐含量较低,可以放心食用,但在夏季时呈上升趋势。Objective:To analyze the changes of nitrite content in cooked meat and to provide help for food safety.Method:200 samples of cooked meat collected from January 2022 to December 2022 were selected to determine the content of nitrite by the second spectrophotometric method.The content of nitrite and the unqualified rate of cooked meat samples collected from different types of cooked meat samples(brined meat food,cold meat food,barbecue meat food),different sources of cooked meat samples(supermarkets,farmers'markets,circulation vendors),different seasons(spring,summer,autumn,winter)were compared.Result:The comparison of different types of cooked meat samples,cooked meat samples(P>0.05).Conclusion:The cooked meat food collected in this study has low nitrite content and can be used safely,but it is increasing in the summer.
