【摘要】 采用气相色谱-质谱联用法,对食品接触材料中多环芳烃在水、乙酸(体积分数为3%)、乙醇(体积分数为10%)和异辛烷等4种食品模拟物中的迁移规律进行了研究,研究迁移量与实验的温度、时间和模拟物属性等参数的关系。结果表明:模拟物的属性对迁移行为有显著影响,迁移量随温度的升高和时间的增加而变大。更多还原

【Abstract】 Using gas chromatography/mass spectrometry(GC/MS), we researched for migration rule of polycyclic aromatic hydrocarbons in food contact materials to 4 simulants of water, acetic acid (volume fraction 3%), ethanol (volume fraction 10%) and isooctane. The purpose was to study the relationship ofmigration amount with migraion time, food simulant temperature, food simulant properties. The results showed that the nature of food simulant has prominence influence on migration action, migration quantity increases with temperature rising and time increasing.更多还原
