中文摘要: 采用固相微萃取法分别对奶牛乳、水牛乳和牦牛乳的挥发性成分进行萃取,经气相色谱-质谱联用仪分析。结果显示,奶牛乳中共鉴定出17种挥发性物质,主要包括酮类、酸类和醛类;水牛乳中共鉴定出16种挥发性物质,主要包括酮类、芳香族及萜烯类、酸类和醛类;牦牛乳中共鉴定出37种挥发性物质,主要包括酮类、酸类、芳香族及萜烯类、酯类、醛类和内酯类。经分析,3种牛乳样品的挥发性物质组成呈现一定的属内差异性和属间相似性。
Abstract:The volatile flavor components of cattle milk(CM),buffalo milk(BM)and yak milk(YM)were extracted by headspace solid-phase micro-extraction,and then analyzed by gas-chromatography mass-spectrometry (HS-SPME-GC/MS).The results showed that,seventeen volatiles were identified from CM,mainly including ketones,acids and aldehydes;sixteen volatiles were identified from BM,mainly including ketones,aromatic compounds,acids and aldehydes;thirty-seven volatiles were identified from YM,mainly including ketones,acids,aromatic compounds,esters,aldehydes and lactones.According to the comparative analysis,there are variabilities within genus and similarities beyond genus among the volatiles of the three milk samples.
