河南省市售食用植物油中氯丙醇酯污染状况分析Pollution status of MCPD ester in edible vegetable oils in Henan province

Abstract

旨在为河南省食品安全风险监测提供参考，对河南省市售的205份食用植物油中3-氯-1，2-丙二醇酯(3-MCPD酯)和2-氯-1,3-丙二醇酯(2-MCPD酯)的污染状况进行调查分析。结果显示：205份食用植物油中，3-MCPD酯污染水平高于2-MCPD酯，其中3-MCPD酯检出率为79.0%，均值为1.83 mg/kg，中位值为1.30 mg/kg；大豆油的3-MCPD酯检出率最高，为93.3%，中位值为1.72 mg/kg，其次是花生油，检出率为89.2%，中位值为1.06 mg/kg，橄榄油的3-MCPD酯和2-MCPD酯污染水平最低；2021年食用植物油中3-MCPD酯、2-MCPD酯检出率均高于2020年；城市、农村人群经由食用植物油摄入3-MCPD酯健康风险较低。不同食用植物油氯丙醇酯的污染水平差别较大，虽然居民经食用植物油摄入3-MCPD酯健康风险较低，但需要继续加强监测。In order to provide reference for food safety risk monitoring in Henan province, the pollution status of 3-chloro-1,2-propanediol(3-MCPD) ester and 2-chloro-1,3-propanediol(2-MCPD) ester in 205 edible vegetable oils sold in Henan province was investigated and analyzed. The results showed that the pollution level of 3-MCPD ester was higher than that of 2-MCPD ester in 205 edible vegetable oils. The detection rate of 3-MCPD ester was 79.0%, with an average value of 1.83 mg/kg and a median value of 1.30 mg/kg. The detection rate of 3-MCPD ester in soybean oil was the highest (93.3%), and the median value of 3-MCPD ester was 1.72 mg/kg. The second was peanut oil, the detection rate was 89.2%, and the median value was 1.06 mg/kg. Olive oil had the lowest pollution levels of 3-MCPD ester and 2-MCPD ester. The detection rates of 3-MCPD ester and 2-MCPD ester in edible vegetable oil in 2021 were higher than those in 2020. The health risk of 3-MCPD ester intake through edible vegetable oil in urban and rural populations was low. The pollution levels of different edible vegetable oils vary greatly, and although the health risk of residents ingestion of 3-MCPD ester through edible vegetable oils is low, it needs to continue to strengthen monitoring.
