基于GC-QTOF-MS对物理回收的食品接触用再生高密度聚乙烯中迁移物的非靶向筛查OA北大核心CSTPCD
Non-targeted Screening for Migrants in Physically Recycled Food Contact High-Density Polyethylene Using Gas Chromatography Quadrupole Time-of-Flight-Mass Spectrometry
以3家企业提供的21种食品接触用再生高密度聚乙烯(recycled high-density polyethylene,rHDPE)样品在60℃条件下与两种代表性食品模拟物(95％乙醇、4％乙酸溶液)接触10 d作为迁移实验条件,利用气相色谱-串联四极杆飞行时间质谱检测迁移到食品模拟物中的物质.被筛查出的161种物质根据其毒性进行分级(由低至高分为Ⅰ～Ⅳ级),其中毒性Ⅲ和Ⅳ级的有59种,且其预测辛醇/水分配系数大于毒性Ⅰ、Ⅱ级的物质.被筛查的物质…查看全部>>
A total of 21 kinds of recycled high-density polyethylene(rHDPE)in contact with food were selected from three companies.Migration experiments were performed by contacting these samples with two representative food simulants(95％ethanol and 4％acetic acid)at 60 ℃ for 10 days.The migration of substances to food simulants was detected by gas chromatography quadrupole time-of-flight-mass spectrometry(GC-QTOF-MS).Altogether 161 substances were selected and classifi…查看全部>>
