低密度聚乙烯薄膜中芥酸酰胺的检测及其向食品模拟物的迁移
Detection of Erucamide in Low-density Polyethylene Films and Its Migration to Simulant Foods
摘要
Abstract
The contents of erucamide in three types of low-density polyethylene (PE-LD) films were detected by gas chromatography-mass spectrometry (GC-MS),and the migration of erucamide from PE-LD films to a simulant food was investigated.The threshold of toxicological concern (TTC) was also used to assess the safety of erucamide in foods.The results indicated that the erucamide standard curve presented a good linear relationship (R=0.999 3) in the range of 100~ 5 000μg/L.The limit of detection of erucamide was 30 μg/L,the recovery were in the range of 78.3 %~115.6 % with a RSD of 2.9 %~11.6 %.The migration of erucamide increased with the increase of time,temperature and erucamide concentration in the certain range.The partition coefficient of erucamide between PE-LD and simulant foods increased slightly with the increase of erucamide concentration in PE-LD.关键词
