摘要: Abstract Food preparation and storage materials are often subjected to stressful conditions such as scraping cleaning with abrasive pads throughout their lifecycle. In general, understanding potential nanoparticle migration when in contact food is important assessing safety. A ceramic-coated fry pan a ceramic sauce pot (both commercially available) were evaluated for under three consumer use conditions. Washing, scouring, scratching simulated by linear abrasion using scrubbing pads, steel wool tungsten carbide burr attachments, respectively. Migration of titanium (Ti) silicon (Si) was 3% acetic acid simulant. Ti Si concentrations simulant generally higher the scenarios than fresh/unused pans. Titanium dioxide (TiO2) (SiO2) nanoparticles detected most aggressive scenario attachment. TiO2 SiO2 particle number on order 108 107 particles dm−2, median diameters 250 nm 460 nm, The aluminum (Al) concentration migrating from also pots, but without any detectable migration.
