Impact of Additives on Migration of Silver from Nanosilver-Plastic Food Packaging to Food Simulants

摘要: This study aimed to explore the effects of additives in nanosilver packaging on migration silver(Ag) into food simulants. Two films, blank nanosilver-polyethylene film and containing additives, which were Irganox 1076, 168, light stabilizer 622 944, soaked simulants 3 g/100 mL aqueous acetic acid(m/V) or 50% ethanol(V/V) at 20, 40 70 ℃ for 1–30 h, digested with electric heating digestion. Then initial content silver films amount migrated determined by inductively coupled plasma mass spectrometry(ICP-MS). The spike recoveries Ag from simulant ranged 84.19% 115.69% relative standard deviation(RSD) between 3.21% 8.75%. results indicated that start 8 hours, two was promoted presence films. In addition, increased gradually increasing temperature time both At balance, hindered movement. acid higher than ethanol.
