摘　　要：采用火焰原子吸收法对小尾寒羊胴体不同部位的Ca,Fe,K,Cu,Zn和Mg等矿物元素的含量进行了分析测定。该法的加标回收率为96.9%—104.2%,RSD值小于2.0%,具有良好的准确度和精密度。研究结果表明:小尾寒羊肉中Ca,Fe,K,Zn和Mg含量丰富,颈肉中Ca的含量最高,肋肉和腰肉中Mg的含量较高,心和肝中Fe的含量较高,心和颈肉中Zn的含量较高。此测定结果可为探讨羊肉中矿物元素的含量与其代谢调节功效的相关性提供科学依据。The mineral elements Ca,Fe,K,Cu,Zn and Mg in different positions of small-tail han sheep carcass were determined by FAAS.The recovery obtained by standard addition method is between 96.9% and 104.2%,and the RSD is lower than 2.0%.The small-tail han sheep meat is rich in mineral elements such as Ca,Fe,K,Zn and Mg.The neck meat has the highest content of Ca.The content of Mg is relatively high in the ribs meat and the waist meat. The content of Fe is relatively high in the heart and the liver.The content of Zn is relatively high in the heart and the neck meat.The results will provide scientific data for the study on the elements in sheep meat and on their relativity of efficacy of metabolism adjustment.
