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

消费者使用对市售陶瓷炊具中纳米颗粒释放的影响

摘要 食品制备和储存材料在其整个生命周期中经常受到压力条件的影响，例如用磨料垫刮擦和清洁。一般来说，了解与食物接触时潜在的纳米颗粒迁移对于评估其安全性很重要。在三种消费者使用条件下评估了陶瓷涂层煎锅和陶瓷酱锅（均市售）的纳米颗粒迁移。分别使用擦洗垫、钢丝绒和碳化钨毛刺附件通过线性磨损模拟洗涤、擦洗和刮擦条件。使用 3% 乙酸作为食品模拟物评估钛 (Ti) 和硅 (Si) 的迁移。在消费者使用场景下，模拟物中的 Ti 和 Si 浓度通常高于新鲜/未使用过的平底锅。二氧化钛 (TiO2) 和二氧化硅 (SiO2) 纳米颗粒在模拟物中检测到，在通过碳化钨毛刺附件磨损模拟的最具侵略性的使用场景下。TiO2 和 SiO2 粒子数浓度分别为 108 和 107 个粒子 dm-2，中值直径分别为 250 nm 和 460 nm。在消费者使用场景下，从酱锅迁移的铝 (Al) 浓度也高于新鲜/未使用的锅，但没有任何可检测到的纳米颗粒迁移。分别。在消费者使用场景下，从酱锅迁移的铝 (Al) 浓度也高于新鲜/未使用的锅，但没有任何可检测到的纳米颗粒迁移。分别。在消费者使用场景下，从酱锅迁移的铝 (Al) 浓度也高于新鲜/未使用的锅，但没有任何可检测到的纳米颗粒迁移。
