摘　　要：目的 测定安徽省市售的鸡肉、鸡蛋、鸡胗和鸡肝样品中铁、铜、锌、硒、钼5种必需微量元素含量,并对其营养价值进行评价。方法 采集安徽省16个市市售的237份鸡产品,用电感耦合等离子体质谱法测定样品中铁、铜、锌、硒、钼含量,计算中位数和营养价值质量指数(INQ)。结果 237份鸡肉、鸡蛋、鸡胗、鸡肝样品中,铜的中位数分别为0.41、0.59、0.85、3.68 mg/kg,铁的中位数分别为5.96、18.36、19.42、100.86 mg/kg,锌的中位数分别为11.62、12.42、25.41、35.83 mg/kg,硒的中位数分别为0.10、0.24、0.19、0.51mg/kg,钼的中位数分别为0.02、0.05、0.04、0.63mg/kg。鸡肉中铁、铜、锌、硒、钼的INQ分别为0.57、0.77、1.75、2.51、0.37;鸡蛋中铁、铜、锌、硒、钼的INQ分别为1.96、1.25、2.20、6.81、1.05;鸡胗中铁、铜、锌、硒、钼的INQ分别为3.21、2.12、5.40、6.85、0.87;鸡肝中铁、铜、锌、硒、钼的INQ分别为13.60、21.67、7.71、22.38、12.41。结论 鸡蛋的营养价值优于鸡肉,可作为铁、铜、锌、硒、钼膳食优质来源;鸡肝的营养价值优于鸡胗,可作为铁、铜、锌、硒、钼补充的良好来源。Objective To determine the content of five essential trace elements namely iron,copper,zinc,selenium,and mo-lybdenum in chicken,eggs,chicken gizzards,and chicken liver samples sold in Anhui Province,and evaluate their nutrition-al value.Methods The contents of iron,copper,zinc,selenium and molybdenum in 237 chicken products sold in 16 cities of Anhui Province were determined by inductively coupled plasma mass spectrometry(ICP-MS)and the median and index of nutritional quality(INQ)were calculated.Results In 237 chicken,egg,chicken gizzard,and chicken liver samples,the median values for copper were 0.41,0.59,0.85 and 3.68 mg/kg,respectively.The median values for iron were 5.96,18.36,19.42 and 100.86 mg/kg,respectively.The median values for zinc were 11.62,12.42,25.41 and 35.83 mg/kg,re-spectively.The median values for selenium were 0.10,0.24,0.19 and 0.51mg/kg,respectively.The median values for mo-lybdenum 0.02,0.05,0.04 and 0.63mg/kg,respectively.The INQ of iron,copper,zinc,selenium and molybdenum in chicken were 0.57,0.77,1.75,2.51 and 0.37,respectively.The INQ of iron,copper,zinc,selenium and molybdenum in eggs were 1.96,1.25,2.20,6.81 and 1.05,respectively.The INQ of iron,copper,zinc,selenium and molybdenum in chick-en gizzards were 3.21,2.12,5.40,6.85 and 0.87,respectively.The INQ of iron,copper,zinc,selenium and molybdenum in chicken liver were 13.60,21.67,7.71,22.38 and 12.41,respectively.Conclusion Eggs have better nutritional value than chicken and can be used as a high-quality source of iron,copper,zinc,selenium and molybdenum in the diet.The nutritional value of chicken liver is superior to that of chicken gizzards,and it can be a good source of iron,copper,zinc,selenium and molybdenum supplementation.
