摘要
目的了解中国部分食品中硼的本底含量及居民膳食硼的摄入情况。方法 2010年在全国12个省市采集谷物类、肉类及水果类食品样品1035份,用电感耦合等离子体质谱(ICP-MS)法检测样品中硼含量。结合2002年居民营养与健康状况调查结果对中国城乡居民硼的平均摄入量进行初步估计。结果在所检测的食品类别中,大豆是硼含量最高的食品,其本底含量为39.46mg/kg,其次是水果和猪肉,本底含量在4～7mg/kg之间,牛羊肉以及粮谷类的大米和小麦中硼含量较低,本底含量不超过4mg/kg。初步估计了我国城乡居民膳食日均硼的摄入量为1.62mg,大米是膳食硼的主要来源。结论不同类别食品含硼量差异较大,大豆是富硼食品。若无违法添加情况,中国居民膳食硼摄入量处于安全范围。
Objective To learn boron background value of some foodstuffs in China and estimation the primary intake of boron.Methods A total of 1035 grain,meat and fruit samples collected from 12 provinces in 2010 were analyzed for boron by ICP-MS.The primary intake of boron was estimated by using the data of ＂Survey on the Status of Nutrition and Health of Chinese People＂ in 2002.Results Soybeans contain the highest concentration of boron among all the surveyed foodstuffs,with the background valued is 39.46mg/kg.Fruit and pork contain second highest concentration of boron,with the background value range from 4mg/kg to 7mg/kg.Beef,mutton,rice and wheat flour contain less boron than other foodstuffs,with background value less than 4mg/kg.The primary intake of boron for Chinese habitants is 1.62mg per day and rice is the main source of dietary boron.Conclusion Boron concentration varies in different foodstuffs and soybeans are rich in boron.The average intake of boron for Chinese habitants was among the safe range if no illegal boron added to food.
