【摘要】 目的：通过对2019—2020年河南省监督抽检食品的过氧化值结果进行分析，为食品监管部门提供数据支持。方法：按照《食品安全国家标准 食品中过氧化值的测定》(GB 5009.227—2016)中第一法滴定法对河南省18个地市按照要求抽取的2019年5个食品大类共1 663批样品，2020年10个食品大类共1 698批样品进行检测，结果依据不同类别食品的国家限量标准进行判定。结果：通过试验发现炒货食品及坚果制品、方便食品中过氧化值超标率较高，2019年的炒货食品及坚果制品类、方便食品类超标率分别为3.0%和3.2%，2020年的炒货食品及坚果制品类、方便食品类超标率分别为2.1%和3.2%。结论：为了保障食品安全，相关部门应加大对过氧化值高和超标率高的食品种类的监管，消费者应尽量减少此类产品的食用。更多还原

【Abstract】 Objective:The peroxide value in food samples during 2019 and 2020 was analyzed by this study.It could provide information for supervision department to monitor food safety.Method:According to the first titration method in GB 5009.227—2016 national food safety standard determination of peroxide value in food.In 18 cities of Henan province,1 663 batches of food samples containing 5 categories were selected in 2019,and 1 698 batches of food samples containing 10 categories were selected in 2020.The results were determined according to the national limit standards for different types of food.Result:It revealed that the peroxide value was high in roasted nuts and instant foods.It revealed that the substandard rate of peroxide value was high in roasted nuts and nut products,and instant foods.The substandard rates in roasted nuts and nut products,and instant foods of 2019 were 3.0% and 3.2% respectively.The substandard rates in roasted nuts and nut products,and instant foods of 2020 were 2.1% and 3.2% respectively.Conclusion:In order to ensure food safety,the supervision department need to emphatically monitor the food categories with high peroxide value and high substandard rate,and the consumer should minimize ingestion of these food products.更多还原
