中文摘要:
      目的 对密胺餐具中三聚氰胺和甲醛迁移量进行调查研究,并对数据进行分析。方法 在上海的企业和消费市场采集密胺餐具共40份,采用红外光谱法进行材料鉴别,依照GB 4806.7—2016《食品安全国家标准 食品接触用塑料材料及制品》和GB 31604.1—2015《食品安全国家标准 食品接触材料及制品迁移试验通则》进行迁移试验,测定三聚氰胺和甲醛迁移量。结果 密胺餐具存在材质未标识、标识不清或标识有误的现象;脲醛树脂中三聚氰胺和甲醛的迁移量均高于密胺树脂,且迁出量与温度呈正相关。结论 脲醛树脂应用于餐具存在风险,国家标准中有必要增加密胺材质鉴定检测方法。
Abstract:
      Objective To investigate the migration of 2,4,6-triamino-1,3,5-triazine and formaldehyde from melamine food container. Methods Samples which were collected from markets in Shanghai were identified and categorized using infrared spectroscopy. Then the migration of2,4,6-triamino-1,3,5-triazine and formaldehyde were tested referring to GB 4806.7-2016 and GB 31604.1-2015. Results Labelling of some samples were absent, incomplete or even incorrect. The migration amounts of formaldehyde from food container made of urea-formaldehyde resin were much higher than that of melamine. Conclusion Due to the high risk caused by migration of formaldehyde from urea-formaldehyde resin, methods should be established to identify different kind of resin of which the food containers were made.
