摘　　要：为了解当地主要食物必需元素含量，用原子吸收分光光度计火焰法，测定了９１种食物中锰、锌、铜、铁、镁的含量。结果显示豆类、麦仁及黑大米锰含量多于其它食物；畜禽肉、内脏富含锌、铜和铁；小麦粉、干豆类、豆腐、菠菜、苔菜等含铁较多。１４种淡水鱼中四种必需微量元素含量均较少。镁在各类食物中含量差异较大，粮谷类普遍高于其它类食物。The contents of Mn,Zn,Cu,Fe and Mg in 91 Kinds of food were determined by atomic absorption spectrophotometry. The results show that Mn is higher in beans and black rice than in other food. Zn,Cu and Fe are more in meat and viscera. Fe also is more in wheat flour, dried bean, bean curd and spinach. Four essential trace elements are less in 14 kinds of freshwater fish. Mg in grains is generally higher than in other food.
