Abstract
The aim of this study was to investigate the possible migration of nanosilver from the commercially available nanosilver antibacterial disposable spoons to food simulating solutions and find out a relationship between migration and conformance with the external conditions. Migration experiments were carried out according to the Chinese standard (GB/T 5009.60-2003), to cover a variety of food simulants and use conditions. Several experimental factors influenced nanosilver release: food simulant, temperature and storage time. An Inductively Coupled Plasma Mass Spectroscopy (ICP-MS) was employed to quantify the total and migrated silver concentration and results demonstrated an increasing migration of nanosilver with storage time and temperature conditions. Meanwhile, Scanning Electron Microscopy/Energy Dispersive Spectrometer (SEM/EDS) was applied to identify the existence and the morphology of nanosilver.
