普洱茶果油的香气成分鉴定

Identification of aroma components in Pu'er tea seed oil

以普洱茶籽油为对象,采用气相色谱-质谱联用(GC-MS)、归一化技术,分析鉴定出茶籽油中30种挥发性物质,它们的分子量多在100左右,主要为醇、醛、酮、酯类物质,约占挥发性成分总量的99.7%;香气成分中同分异构体有6种,占香气成分的53.3%;30种挥发性物质相互作用构成了普洱茶果油独特的天然香气。

30 aroma components in Pu＇er tea seed oil were identified by gas chromatography-mass spectrometry （GC-MS） and normalized technology. The molecular weight of most identified aroma components were about 100. They mainly belonged to alcohol, aldehyde, ketone and ester, and accounted for 99.7% of total volatiles. There were 6 isomerides which composed 53.3% of the aroma components. The interaction of 30 aroma components induced the natural unique aroma of Pu＇er tea seed oil.
