塑包山茶油中邻苯二甲酸酯类增塑剂危害安全水平及迁移规律的研究

Research on safety level and migration law of phthalic acid esters in camellia oil packaged with different plastics

目的通过对当前市场中的PET、PP、PE 3种塑包材质包装的山茶油中的邻苯二甲酸酯类增塑剂(PAEs)残留进行监测,了解市售山茶油中增塑剂残留状况与危害水平,为山茶油安全包装提供技术依据。方法模拟商品货架的摆放条件12个月,应用凝胶渗透色谱—气相色谱质谱法对山茶油中的PAEs迁移水平进行定期监测。结果山茶油中存在着微量的PAEs,其主要成分为邻苯二甲酸二丁酯(DBP)与邻苯二甲酸二(2-乙基)己酯(DEHP)。结论在山茶油品质保持期内,以上3种塑包材质包装的山茶油中的PAEs特定迁移量均低于国家卫生部的限量规定,正常生产条件下山茶油加工企业引用上述塑包材质是安全的。

Objective The residue levels of phthalic acid esters(PAEs) in camellia oil packaged with 3 different plastic(PET, PP, and PE) in the current market were detected, to know plasticizers residues and hazard level in camellia oil and provide technical basis for safety packaging of camellia oil.MethodsSimulating the condition of store shelves for 12 months, migration law of PAEs was studied by the use of gel permeation chromatography and gas chromatography-mass spectrometry.ResultsThere were traces of PAEs in camellia oil, including dibutyl phthalate (DBP) and di 2-ethyl hexyl phthalate (DEHP).Conclusion The migration levels of PAEs in camellia oil packaged with different plastics (PET, PP, and PE) were lower than national standard during the shelf life, which meant it was safe to package camellia oil with these plastics for camellia oil processing enterprises under the condition of normal production.
