摘要:

采用现行国家标准GB 31604.30—2016中邻苯二甲酸酯迁移量的检测方法,对市售食品级保鲜膜中邻苯二甲酸酯迁移量及其向食品模拟物中的迁移行为进行分析。研究了温度、时间、食品模拟物对邻苯二甲酸酯迁移行为的影响。结果表明,对于3种市售食品级聚氯乙烯(PVC)保鲜膜,均检测到邻苯二甲酸二(2⁃乙基)己酯(DEHP)的迁移量。对于同一食品模拟物,在不同实验温度时间下,PVC保鲜膜中DEHP的迁移量随着温度的升高、时间的延长而增大;对于不同食品模拟物,在相同实验温度时间下,PVC保鲜膜中DEHP在油类模拟物及高浓度酒精类模拟物中的迁移量大于其在水性和酸性模拟物中的迁移量。

Abstract:

The migration of phthalate esters from cling films and their migration behavior to simulants were analyzed using the test method in accordance with GB 31604.30—2016. The effects of temperature, time, and food simulants on the migration behavior of phthalate esters were investigated. The results indicated that for all three commercially available food⁃grade poly(vinyl chloride) (PVC) cling films, the migration of di(2⁃ethylhexyl) phthalate (DEHP) was detected. For the same food simulant, the migration of DEHP in PVC cling films increased with an increase in temperature and time at different experimental temperatures and times. For different food simulants, the migration of DEHP in PVC cling films in oil simulants and high alcohol simulants was greater than that in aqueous and acid simulants at the same temperature and time.

Key words: phthalate, poly(vinyl chloride), migration behavior, food simulant
