摘  要:
采用顶空固相微萃取(solid-phase microextraction,SPME)技术结合气相色谱-质谱法(gas chromatography-mass spectrometry,GC-MS),对新疆多浪羊不同部位脂肪组织中挥发性风味物质的组成进行研究,共检测出78种化合物,其中以酸类、酯类和醛类为主。尾部脂肪组织中酸类化合物占37.50%,皮下脂肪组织中酸类化合物占41.38%,肠道脂肪组织中酯类化合物占43.48%,肾脏周围脂肪组织中酸类化合物占29.63%。不同部位脂肪组织中挥发性风味化合物的组成不同,酸类化合物为主要成分,推测短链挥发性脂肪酸是多浪羊肉特征风味的主要组成成分。

摘  要:
This experiment investigated the volatile flavor components of different adipose tissues in Duolang sheep in south Xinjiang using headspace solid phase microextraction combined with gas chromatography mass spectrometry(SPME-GC-MS). A total of 78 compounds were detected, mainly including acids, esters and aldehydes. Acids accounted for 37.50%, 41.38%, and 29.63% of the total volatiles in tail, subcutaneous, and perirenal adipose tissues, respectively. And esters accounted for 43.48% in intestinal tissues. The volatile flavor compositions of these different adipose tissues were different, which were all dominated by acids. It was speculated that short-chain volatile fatty acids contributed dominantly to the characteristic flavor of the meat of Duoloang sheep.
