摘　　要：利用全自动氨基酸分析仪测定不同产地山药粉中游离氨基酸和水解氨基酸的含量并进行分析。结果表明,不同产地山药粉中含有所检测的17种氨基酸,包括7种人体必需氨基酸。不同品种山药粉中游离氨基酸总量从高到低依次为河北小白嘴>河北高阳紫药>山东鸡皮糙>山东陈集铁棍>河南温县铁棍>山东西施>山西永济铁棍>山西运城铁棍。不同品种山药粉中水解氨基酸总量差异不明显,其中必需氨基酸含量从高到低依次是亮氨酸>苯丙氨酸>缬氨酸>异亮氨酸>苏氨酸>赖氨酸>蛋氨酸。The contents of free amino acids and hydrolyzed amino acids in yam powder from different origins were determined by automatic amino acid analyzer and analyzed.The results showed that yam powder from different origins contained 17 kinds of amino acids detected,including 7 kinds of essential amino acids.The total content of free amino acids in different varieties of yam powder from high to low was Hebei Xiaobaizui>Hebei Gaoyang Ziyao>Shandong Jipicao>Shandong Chenji Tiegun>Henan Wenxian Tiegun>Shandong Xishi>Shanxi Yongji Tiegun>Shanxi Yuncheng Tiegun.There was no significant difference in the total content of hydrolyzed amino acids in different varieties of yam powder,and the order of essential amino acid content from high to low was leucine>phenylalanine>valine>isoleucine>threonine>lysine>methionine.
