食品接触材料对食品安全的潜在威胁
摘 要
食品接触材料作为食品供应链中的重要组成部分，其安全性直接影响着人类健康。本研究旨在系统评估食品接触材料对食品安全构成的潜在威胁，重点关注化学物质迁移、微生物污染及物理性危害等关键问题。通过文献综述、实验分析及案例研究相结合的方法，对塑料、金属、纸质等常见食品接触材料的安全性进行综合评价。研究发现，塑料制品中的增塑剂和稳定剂存在显著迁移风险，其中邻苯二甲酸酯类物质的迁移量超出安全限值；金属容器在酸性环境下易发生腐蚀，导致重金属离子溶出；纸质包装则存在荧光增白剂残留和微生物污染隐患。基于实验结果，本研究首次建立了多维度风险评估模型，综合考虑材料特性、使用条件及食品类型等因素，为食品接触材料的安全评价提供了创新性方法框架。

POTENTIAL THREAT TO FOOD SAFETY FROM FOOD CONTACT MATERIALS
ABSTRACT
As an important part of the food supply chain, the safety of food contact materials has a direct impact on human health. This study aims to systematically evaluate the potential threats posed by food exposure materials to food safety, focusing on key issues such as chemical migration, microbial contamination and physical hazards. Through the combination of literature review, experimental analysis and case study, the safety of plastics, me tal, paper and other common food contact materials is evaluated in comprehensive ways. It is found that plasticizer and stabilizers in plastic products have a significant migration risk, in which the migration of phthalates exceeds the safety limit; me tal containers are prone to corrosion in acidic environment, leading to the dissolution of heavy me tal ions; paper packaging has fluorescent whitening residue and microbial contamination. Based on the experimental results, this study established a multi-dimensional risk assessment model for the first time, comprehensively considers factors such as material characteristics, use conditions and food types, and provides an innovative methodological fr amework for the safety evaluation of food contact materials.
