苏尼特羊和小尾寒羊的屠宰性能、肉品质、脂肪酸和挥发性风味物质比较

摘要

The slaughter performance of Sunit sheep and Small-Tailed Han sheep (5-month-old, 10 animals for each breed) was investigated. The quality, fatty acid composition and volatile compounds of Longissimus dorsi muscles from these lambs were comparatively evaluated. The results showed that the meat percentage and bone to meat ratio of Sunit lambs were significantly greater than those of Small-Tailed Han lambs (P 0.05).羊肉的挥发性成分主要由羰基化合物和醇类化合物组成,不同品种对挥发性成分的相对含量和构成影响很大,苏尼特羊的醛类和酮类化合物含量高于小尾寒羊,但醇类化合物含量低于小尾寒羊,筛选主要风味化合物为己醛、辛醛、壬醛、1-辛烯-3-醇和2,3-辛二酮.
