摘 要：
建立采用高效液相色谱法对塑料食品包装材料中双酚A向食品模拟物迁移量的检测方法。使用4种食品模拟物:水、质量分数为4%乙酸溶液、体积分数30%的乙醇溶液和脂肪类模拟物(正己烷、异辛烷和橄榄油)。结果表明,双酚A在与食品塑料包装接触过程中,无论在何种情况下都会向食品模拟物中迁移,尤其向醇类模拟物中迁移最严重;在温度超过60℃时,双酚A向食品模拟物中的迁移率骤增;在微波加热条件,高火700W功率时双酚A向食品模拟物中的迁移速率最快。该方法检测限为0.3ng/mL,线性范围为0.5～100ng/mL,线性相关系数为0.9997,回收率在92.0%～102.4%之间,相对标准偏差≤2.84%(n=5)。

摘 要：
A high performance liquid chromatography method was developed for determining the migration of bisphenol A from plastic food packaging materials into food simulants such as water,4% acetic acid solution(weight fraction),30% ethanol solution(volume fraction) and fat simulants(hexane,isooctane and olive oil).The results showed that bisphenol A could migrate to foods from packaging materials during the contact with foods,especially in alcohol simulants.The migration rate of bisphenol A from packaging materials to foods revealed a dramatic increase at the temperature of over 60 ℃.Under the condition of microwave heating,microwave power at 700 W could result in the fastest migration of bisphenol A.The detection limit of the method was 0.3 ng/mL with a linear range of 0.5-100 ng/mL and a linear correlation coefficient of 0.9997.The average recovery rate of the method was 92.0%-102.4% with a relative standard deviation(RSD) of less than 2.84%.
