中文摘要:

      食品安全问题关系国计民生, 近年来食品安全质量有了明显提高, 但容易忽视却现实存在的食品安全隐患即食品接触材料, 尤其是大量使用的塑料食品包装材料中有害物质迁移到食品中对食用者造成的潜在危害无时不在。本文综述了塑料食品包装材料中4大类添加剂, 包括增塑剂、紫外线吸收剂、抗氧化剂、荧光增白剂4类受限物质迁移至食品及食品模拟液中的风险及存在的安全问题、食品模拟物及迁移试验、受限物质检测研究现状, 比较了我国与发达国家关于食品接触材料受限物质的法律法规及迁移限量, 提出制备受限物质质控标准品对受限物质检测准确性和风险评估的重要性等。本文对加强我国塑料食品接触材料中受限物质的使用与监管、检测结果的方法学验证技术的开发, 塑料食品接触材料添加剂的使用范围、使用限量及受限物质迁移限量值的制定, 及对基于受限物质的食品安全风险评估等均具有明确的参考意义和数据支持。

英文摘要:

      Food safety is related to the national economy and the people’s livelihood. Food safety and quality have been significantly improved in recent years, but it is easy to ignore the actual food safety hazards that food contact materials, especially the harmful substances in the mass use of plastic food packaging materials, migrate to food and cause potential harm to consumers. This paper reviewed 4 types of additives in plastic food packaging materials, including plasticizer, ultraviolet absorber, antioxidant, fluorescent whitening agent, the risk and safety problems of 4 types of restricted substances migrating to food and food simulants, research status of restricted substance detection, food simulants and migration tests, etc. The laws, regulations and migration limits of restricted substances in food contact materials between China and developed countries are compared, and puts forward the importance of preparing restricted substances quality control products for the detection accuracy and risk assessment of restricted substances. This paper had clear reference significance and data support for strengthening the use and supervision of restricted substances in plastic food contact materials in China, the development of methodological verification technology for test results, the use range and amount of additives in plastic food contact materials and the formulation of migration limit value of restricted substances, and the food safety risk assessment based on restricted substances.
