基于塑料桶装食用油的迁移分析及消费者的安全认知行为

Migration of Harmful Compounds From Packaging Plastic into Vegetable Oil and Consumers' safety awareness

为了揭示食用油塑料桶中有害物质迁移,并分析人们对食用油包装材料的安全认知行为,利用高效液相色谱-质谱(HPLC-MS)联用法初步测试了常见塑料(PE、PET)中化学助剂向食用油的迁移;并基于742位消费者的样本数据,结合相关数据与实际情况,分析了消费者对食用油包装材料安全性的认知和相关态度,研究了其对食用油包装材料的选择和使用情况。结果表明,塑料中有害化学物质向植物油中存在一定程度的扩散和迁移;在消费者对食品质量安全高度关注的背景下,消费者对食用油包装材料的安全相对轻视,对其包装材料的安全性缺乏一定程度的鉴别能力。

In order to reveal people＇s awareness of the harmful substances in migration, and analyses safety cognitive behavior for packaging materials of vegetable oil. The migration behavior of chemicals from the common plastic（PE and PET） into oils was determined with High Performance Liquid Chromatography（HPLC）-Mass Spectrometry（MS）; the consumers＇ perception and attitude about the safety of food packaging material were analyzed, including the consumers＇ choice and using behavior about packaging materials, based on the 742 samples. It was shown that the diffusion and migration of harmful chemicals from the plastic into vegetable oil generally exist. The consumers paid less attention to food packaging safety and it＇s difficult for the consumer to effectively gain relevant knowledge and information about food packaging safety. The lack of ability to identify the safety of food packaging materials leads to the ubiquity of misuse or abuse.
