摘 要:以新疆多浪羊为母本分别与杜泊羊、多浪羊和萨福克羊杂交后代肉质感官及理化指标;采用固相微萃取技术(SPME技术)进行提取,使用气相色谱-质谱仪进行分析测定,比较不同烹饪方式对香气成分的影响。结果表明:萨福克与多浪杂交后代的肉质最好,而杜泊与多浪杂交后代的肉质最差;生鲜羊肉中主要的香气成分为叶醇,而烤羊肉及涮羊肉的主要香气成分为己醛。

Abstract: This study investigated sensory and physicochemical qualities of lamb from Xinjiang Duolang sheep and cross-breeds with Dorper sheep or Suffolk sheep. The volatile aroma compounds of raw and cooked lamb were extracted by solid phase micro extraction (SPME) and comparatively analyzed by gas chromatography-mass spectrometry (GC-MS). The results showed that the meat quality of lamb from Suffolk-Duolan hybrid was the best, while lamb from Dorper-Duolan hybrid had the worst meat quality. The major aroma component of raw lamb was leaf alcohol, whereas for both roast and instant-boiled lamb, hexanal was identified as the predominant aroma compound.

Key words: Xinjiang Duolang sheep; Dorper sheep; Duolang sheep; Suffolk sheep; meat quality; aroma component

我国是羊肉生产大国,产量占全世界第一位。2009年羊存栏量为3.4亿 只左右,出栏23 280.8万只,羊肉产量410万 t[1]。虽然我国在羊肉的生产上有着广阔的消费市场,丰富的绵羊、山羊品种及饲料、饲草、农副产品资源,但是同养羊业发达国家相比,仍然存在着屠宰率低、胴体品质差、人均占有量少、出栏率、出口量低等诸多差距[2]。新疆畜牧业生产区远离工业污染,相对独立的生态区域为牲畜疫病防治提供了天然屏障,使新疆羊肉生产具有无污染、无公害、纯天然的优势。新疆特色羊肉制品肉鲜、味正、风味独特、享誉海内外。新疆是我国五大牧区之一,羊数量大,但肉羊业的发展仍处于初步阶段,如何管好和用好原有的品种资源和引进的品种资源,充分发挥其优良特性,这对新疆肉羊业基地建设以及推动全区经济发展、带动农牧民脱贫致富有着极其重要的现实意义。近年来,人们对肉的品质要求越来越高,羊肉的营养丰富、蛋白质含量高、脂肪含量适中、胆固醇含量低、肌纤维细嫩、柔软、味美多汁,是人们的理想肉食品[3]。……
