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
