摘　　要：利用湿法微波消解全蛋粉、蛋清粉及蛋黄粉,采用原子吸收光谱法测定各样品中钾(K)、铜(Cu)、铁(Fe)、锌(Zn)、钙(Ca)、锰(Mn)、镁(Mg)7种金属元素含量。结果表明,全蛋粉中K,Fe含量高于蛋清粉及蛋黄粉,蛋清粉中Mg含量高于全蛋粉及蛋黄粉,蛋黄粉中Cu,Zn,Ca,Mn含量高于全蛋粉及蛋清粉。全蛋粉中7种元素含量依次为K>Ca>Fe>Zn>Mg>Cu>Mn,蛋清粉中7种元素含量依次为Ca>K>Mg>Fe>Zn>Cu>Mn,蛋黄粉中7种元素含量依次为Ca>K>Zn>Fe>Mg>Cu>Mn。Wet microwave digestion of whole egg powder,egg white powder and egg yolk powder,determination of potassium（K）,copper（Cu）,iron（Fe）,zinc（Zn）,manganese（Mn）,calcium（Ca）,and magnesium（Mg） in each sample by atomic absorption spectrometry. The results show that K and Fe of whole egg powder are higher than that of whole egg powder and egg yolk powder,The content of Mg is higher than that of the whole egg powder and egg yolk powder,Egg yolk powder Cu,Zn,Ca,Mn are higher than that of whole egg powder and egg white powder. The contents of 7 elements in the order of whole egg powder is K〉Ca〉Fe〉Zn〉Mg〉Cu〉Mn,The contents of 7 elements in egg white powder are Ca〉K〉Mg〉Fe〉Zn〉Cu〉Mn,The contents of 7 elements in egg yolk powder are Ca〉K〉Zn〉Fe〉Mg〉Cu〉Mn.
