Abstract
Objective: Analyze the differences in mineral element content in yak meat from Leiwuqi County, Changdu City, Tibet. Methods: This study focuses on 431 yak meat samples from Leiwuqi County, Xizangchang City,including (Kamado Township, Leiwuqi Township, Yiri Township, Changmaoling Township, Gangse Township, Sangdo Township, Binda Township, Shangka Township, Jiasangka Township, Jiduo Township).The contents of K, Na, Ca, Mg, Se, Sr, Mn, Zn and Fe in yak meat were determined by microwave digestion ICP-MS.Analyze the difference of mineral element content in yak meat from different regions and parts. Results: There were extremely significant differences in mineral elements in different parts of the meat of similar Uqi yaks (P<0.01);while there were extremely significant differences in Ca and Se elements (P<0.01) and significant differences in Zn and Fe elements (P<0.05); while there were significant differences in K, Na, Ca, Mg, Se, and Mn elements (P<0.05);. There were extremely significant differences in K, Mg, Se, Zn elements (P<0.01), and significant differences in Na and Ca (P<0.05).;There were extremely significant differences in K, Na, and Mg elements (P<0.01), while there were significant differences in Ca, Mn, and Zn elements (P<0.05); while there were significant differences in K and Mn (P<0.05). There were extremely significant differences in Sr, Zn, and Fe elements (P<0.01);while there was a significant difference in Ca and Fe elements (P<0.05). Conclusion: Yak meat from different regions has higher levels of K, Na, and Mg,Ca, Zn, and Fe take second place,the content of Se, Sr, and Mn is relatively low.The mineral elements in different parts of yak meat include K, Na, Mg in tenderloin, Ca in brisket, Se in hind legs, Sr, Mn in buttocks, and Zn, Fe in tendons, which have advantages in content and quality.
