摘要：

目前微纳米食品接触材料由于优异的性能被广泛关注,然而对食品接触材料中微纳米粒子在食品中的迁移尚未见报道。对微纳米聚丙烯保鲜盒产品进行了食品模拟液浸泡处理,采用扫描电镜(SEM)、X射线能谱仪(EDS)、原子吸收分光光度计(AAS)、激光光散射仪(DLS)等测试手段分析了迁移到食品模拟液中银的形态、含量及粒度分布。实验结果表明,微纳米银会从保鲜盒中迁移出来以微纳米尺寸的颗粒存在于食品模拟液中,并且在油性食品模拟液中的迁出量最大。

Abstract:

Micro／nano food contact materials receive great interests for their excellent properties at present, however, the migration of micro／nano particles from these materials into food has not been reported. The nano polypropylene (PP) chambers were studied, and the morphology,content and particle size distribution of Ag migrated into the selected food simulated solutions were measured by scanning electron microscopy (SEM) with an energy dispersive spectrometer(EDS)accessory, atomic absorption spectrophotometer (AAS), and laser dynamic light scattering (DLS) after the treatment of dipping the chambers in food simulations. The results suggested that macrol/nano sivler could migrate from the chamber into food simulants in the form of micro／nanosized particles, and the maximum migration appears in oilfood simulants.

Key words: microl/nano polypropylene chambers, micro／nano silver, food simulants, migration
