摘要: 选取12月龄海门山羊公、母羊和波尔山羊×海门山羊F1代公羊3个群体为试验素材,分别取颊肌、斜方肌、臂三头肌、背最长肌、股二头肌、股四头肌和腓肠肌7个部位肌肉来研究海门山羊不同部位肌肉中氨基酸的含量。采用高效液相色谱法测定肌肉中氨基酸的种类和含量。结果表明,所测3个类群山羊7个部位的氨基酸均以谷氨酸含量最高;海门山羊(♂)斜方肌的脯氨酸含量显著高于臂三头肌、背最长肌(P<0.05);海门山羊(♀)斜方肌的丝氨酸、甘氨酸、精氨酸、脯氨酸、半胱氨酸和苯丙氨酸的含量显著高于背最长肌(P<0.05);波尔山羊×海门山羊F1(♂)斜方肌的甘氨酸含量显著大于其他部位肌肉中含量(P<0.05);3个类群7个部位的必需氨基酸、鲜味氨基酸和总氨基酸含量均无显著差异(P>0.05),但鲜味氨基酸含量较丰富。总体来说,海门山羊不同类群及不同部位除了个别氨基酸存在差异外,大部分氨基酸均差异不显著,但海门山羊尤其公羊的鲜味氨基酸含量丰富,肉质鲜味较好。

Abstract: To compare the contents of amino acid in different parts muscle of Haimen goats(♂), Haimen goats(♀), Haimen goats and Boer×Haimen F1(♂) goats, these goats were raised under the same condition and slaughtered at 12-month-old to assay the content and variety of amino acid in buccinators, trapezius, triceps brachii, longissimus dorsi, biceps femoris, quadriceps femoris and gastrocnemius, and the amino acid was determined by the method of HPLC.The results showed that there were 17 kinds of amino acid and the content of glutamic acid was the highest in all the amino acid. The proline content of trapezius was significantly higher than that of triceps brachii, longissimus dorsi in Haimen goats(♂) (P<0.05).The content of serine, glycine, arginine, proline, cysteine and phenylalanine of trapezius were significantly higher than that of longissimus dorsi in Haimen goats(♀)(P<0.05).Compared with other anatomical muscles in Boer×Haimen F1(♂) goats, trapezius had the highest glycine values (P<0.05).There were no significant differences (P>0.05) in the content of essential amino acid, total amino acid and delicious amino acid among 3 different groups and 7 anatomical sites,and the content of delicious amino acid for the three groups were abundant. In summery, no significant differences were observed in most of these amino acid among the groups and anatomical sites, except for a little part of amino acid.But for the Haimen goats,especially Haimen goats (♂), had plenty of amino acid and showed a good delicate flavour.
