2023年四川省6个地区本地产白酒中4类化学污染物的检测结果分析

Analysis on the detection results of 4 kinds of chemical contaminants in local produced liquor in 6 regions of Sichuan Province in 2023

目的对四川省6个地区本地产白酒中4类化学污染物的含量水平进行测定并对结果进行分析,了解本地产白酒的污染状况,为制定白酒监管政策提供依据。方法按照《2023年四川省食品安全风险监测实施方案》的要求,对采自成都、宜宾、泸州、遂宁、德阳和绵阳6个地区的181份本地产白酒样品中的铅、氰化物、甲醇和18种邻苯二甲酸酯类物质的含量进行测定,并依据食品安全国家标准或相关文件对检测结果进行分析评价。结果所有样品均未检出铅;甲醇检出率为97.2%,合格率为100.0%;氰化物检出率为97.8%,合格率为100.0%。共有DBP、DEHP、DMP和DIBP等4种邻苯二甲酸酯类物质检出,检出率分别为77.9%、12.1%、21.0%和42.5%;其中DBP的超标率为9.4%,最高检出含量为10.3 mg/kg。整体上散装白酒中DBP的检出率和超标率均高于定型包装白酒。结论2023年四川省6个地区本地产白酒总体合格率为90.6%。除DBP外,所有检测指标含量均符合食品安全国家标准或相关文件要求;个别样品DBP远超最大限量,应针对性地加强监测以保障消费者食品安全。

Objective To investigate the contamination status of four kinds of chemical contaminants in local produced liquor from 6 regions in Sichuan province,and to provide scientific evidence of regulatory policies development for liquor.Methods Lead,cyanides,methanol and 18 phthalate esters in 181 liquor samples from 6 regions in Sichuan province were determined in accordance with implementation plan of Sichuan province for food safety risk monitoring in 2023,and the results were analyzed and assessed in accordance with national food safety standards and other relevant documents.Results Lead was not detected in all samples.The detection rate and pass rate of methanol were 97.2%and 100.00%,respectively,and those of cyanides were 97.8%and 100.00%,respectively.Four phthalate esters including DBP,DEHP,DMP and DIBP were detected from 77.9%,12.1%,21.0%and 42.5%of the samples,respectively;For DBP,the over-standard rate was 9.4%,and the maximum detected content was 10.3 mg/kg.Overall,both the detection rate and the over-standard rate of DBP were higher in bulk liquors than in packaged liquors.Conclusions In 2023,the overall qualified rate of local produced liquor in the 6 regions in Sichuan province in terms of lead,methanol,cyanides and phthalate esters was 90.6%.With the exception of DBP,levels of all determined chemical contaminants met requirements in national food safety standards or relevant documents;DBP in a few samples far exceeded the maximum permitted limit,suggesting that pertinent monitoring should be enhanced to ensure food safety for consumers.
