中文摘要:

      随着人们生活节奏的加快, 包装食品越来越受到消费者的青睐。塑料包装材料因来源充足、价格低廉被广泛应用于食品包装材料上。塑化剂中目前以邻苯二甲酸酯类较为常用。塑化剂通过增加塑料大分子链间的距离, 降低塑料分子间的作用力来增加塑料的延展性和韧性。但塑化剂分子的游离性, 使其易于迁移入接触物中。本文介绍了邻苯二甲酸酯类塑化剂的理化性质, 对白酒、食用油等不同类型食品的包装材料中塑化剂的迁移情况以及邻苯二甲酸酯类塑化剂检测方法的相关文献进行梳理总结, 对目前我国塑化剂超标准案屡禁不止的原因进行分析, 为今后食品塑料包装材料发展方向提出建议,同时为塑化剂的深入研究及食品监管部门制定相关法规、标准提供理论参考。

英文摘要:

      With the acceleration of people’s living pace, the packaged foods are becoming more and more popular with consumers. Plastic packaging materials are widely used in food packaging materials due to their abundant sources and low cost. Phthalate esters (PAEs) are the more commonly used plastic plasticizer. Plasticizers can increase plastic ductility and toughness by increasing the distance between the plastic macromolecular chain and reducing plastic intermolecular forces. But the dissociation of plasticizer molecular makes it easy to migrate into the contactant. This paper introduced the physic-chemical characteristics of PAEs, and summarized the migration of plasticizers in different types of food packaging materials such as liquor and edible oil and the detection methods of PAEs in literatures, analyzed the reasons for the large number of cases of plasticizer exceeding the standard in China, and made some recommendations for the development direction of food plastic packaging materials in the future. At the same time, it provided theoretical references for the further research of plasticizers and development of regulations and standards of food supervision departments.
