河南省市售预包装食用植物油质量调查

Quality investigation of prepackaged edible vegetable oils sold in Henan

目的了解河南省市售预包装食用植物油的卫生质量情况。方法2017-2019年在河南省境内抽取样品3257批次,对GB 2716中有限量要求的10个项目进行检测分析,对没有强制性标准限量要求的4个项目进行风险监测。结果总体不合格率为0.92%,苯并[a]芘含量超标是造成样品不合格的主要原因,占检出不合格项次总数的64.52%。从食品细类看,其他食用植物油和芝麻油不合格率较高,不合格率分别为3.85%和2.00%。风险监测项目邻苯二甲酸二(α-乙基)已酯(DEHP)、邻苯二甲酸二丁酯(DBP)、辣椒素总量和玉米赤霉烯酮的超标率分别为18.65%、3.92%、3.97%和1.83%。其中,芝麻油占DEHP或DBP超标总批次的49.17%(149/303)。结论河南省市售预包装食用植物油卫生质量总体良好,但其他食用植物油和芝麻油的质量风险较高,需加强监管。
