2016—2017年广西食用植物油质量安全监测评价分析

Monitoring and evaluation on quality and safety of edible vegetable oil in Guangxi from 2016 to 2017

对广西食用植物油质量安全水平和污染程度进行监测评价。2016—2017年对广西14个地级市共抽检监测食用植物油3821份,按照GB/T 5009检测酸价、过氧化值、浸出油溶剂残留、黄曲霉毒素B1、总砷、铅和苯并(a)芘,并依据GB 2716—2005对食用油进行评价。结果表明:抽检食用植物油总合格率为92.04%;2016、2017年食用植物油合格率分别为96.70%和91.22%,差异有统计学意义(P<0.05)。从种类看,玉米油、芝麻油和其他食用植物油合格率分别为100%、93.75%和99.61%。花生油合格率最低,为87.83%,黄曲霉毒素B1超标是花生油不合格的主要原因,检出率为8.85%。从包装看,预包装食用植物油的合格率(99.70%)明显高于散装(83.72%),差异有统计学意义(P<0.05)。食用植物油生产加工环节的合格率最低,为88.01%。广西玉米油、芝麻油和其他食用植物油相对而言抽检合格率较高,花生油合格率较低,应加强花生油的抽检监测和监督管理,通过严格落实生产经营者主体责任,积极引导消费者科学理性消费,持续深化小油坊专项治理,不断强化质量安全控制技术研究,逐步推进广西食用植物油安全水平稳步提升。

The quality safety level and pollution degree of edible vegetable oil in Guangxi were monitored and evaluated.From 2016 to 2017,3821 edible oils were collected from 14 prefecture-level cities in Guangxi.The acid value,peroxide value,solvent residue of the leached oil,aflatoxin B1,total arsenic,lead and benzo(a)pyrene of edible oil were measured according to GB/T 5009 and evaluated according to GB 2716—2005.The results showed that the total qualified rate was 92.04%.The qualified rates of edible vegetable oils in 2016 and 2017 were 96.70%and 91.22%respectively,and the difference was statistically significant(P<0.05).In terms of edible vegetable oil varieties,the qualified rates of corn oil,sesame oil and other edible vegetable oils were 100%,93.75%and 99.61%,respectively.The qualified rate of peanut oil was the lowest(87.83%).With the detection rate of 8.85%,aflatoxin B1 exceeding the limitation was the main reason for the unqualified peanut oil.From the packaging,the qualified rate of prepackaged vegetable oil(99.70%)was significantly higher than that of bulk(83.72%),the difference was statistically significant(P<0.05).The qualified rate of production and processing of the edible vegetable oil was the lowest(88.01%).There were higher qualified rates in the sampling detection of corn oil,sesame oil and other edible vegetable oils compared with peanut oil in Guangxi.It was necessary to strengthen sampling inspection,monitoring,supervision and management in peanut oil industry so as to gradually promote the safety level of edible vegetable oils in Guangxi by fulfilling responsibility of production operators,actively guiding rational consumption,deepening the special governance of small oil mills,and continuously enhancing research on quality and safety control technologies.
