2019—2020年中国肉制品接触材料膳食暴露评估基础参数

Exposure assessment basic parameters of contact materials for meat product in China from 2019 to 2020

目的掌握中国肉制品食品接触材料的使用情况,构建肉制品食品接触材料膳食暴露评估基础参数数据库。方法基于食品接触材料膳食暴露评估的“接触面积法”所需数据,于2019—2020年在北京、吉林省和江苏省的现场和网上购买预包装肉制品并结合行业调查,通过核查食品标签及红外光谱仪检测获得相关信息,计算肉制品食品接触材料与单位质量食品的接触面积参数(S/V)。结果共采集443份肉制品,获取相关数据14176个,肉制品接触材料涉及聚乙烯(PE)、聚对苯二甲酸乙二醇酯(PET)、聚丙烯(PP)、聚酰胺(PA)、聚氯乙烯(PVC)、聚偏氯乙烯(PDVC)、复合材料以及涂层共8种材质,食品接触材料与单位质量食品的接触面积(S/V)平均值32.92 dm^(2)/kg,最小值0.77 dm^(2)/kg,最大值273.33 dm^(2)/kg。结论基于肉制品食品市场调查构建的肉制品食品接触材料基础参数可为肉制品食品接触材料膳食暴露评估提供数据支持。

OBJECTIVE To master the use of meat products and food contact materials in China,to establish the national database of exposure assessment basic parameters of contact materials for meat product.This database can provide basic data for dietary exposure assessment of food contact materials.METHODS The method was based on the data required for the“contact area method”,and used to study the contact materials of meat product in this study.The main data were the contact area values,ratio of contact areas and unit mass,which were obtained from the investigation of meat products and food contact materials.RESULTS Through investigation and analysis,443 kinds of meat product were obtained,and 14176 related data were obtained,basically covering meat product of similar materials on the market.Food contact materials of meat product by Chinese population mainly include polyethylene,polyethylene terephthalate,polypropylene,polyamide,Polyvinyl chloride,Poly(vinylidene chloride),Composite Material and coating.Average of contact area between food contact materials and food per unit mass or volume(S/V)is 32.92 dm^(2)/kg,minimum of S/V is 0.77 dm^(2)/kg,maximum of S/V is 273.33 dm^(2)/kg.CONCLUSION The basic parameters of meat product contact materials based on the market survey can provide data support for the dietary exposure safety assessment of meat product contact materials.
