摘要:

应用顶空固相微萃取法(HS-SPME)和气质联用(GC-MS)快速测定南果梨果酒中的香气成分。设立不同的温度条件,研究温度对固相微萃法分析南果梨果酒香气成分的影响。结果表明,在不同温度下,酯类和醇类化合物是鉴定出的主要香气成分;乙醇、乙酸乙酯、2- 甲基-1- 丙醇、异戊醇、2- 甲基-1- 丁醇、丁酸乙酯、乙酸异戊酯、3- 甲硫基丙酸乙酯、苯乙醇、癸酸乙酯是不同温度下共有的成分,温度在40℃鉴定出的香气成分种类最多。

Abstract:

Headspace solid-phase microextraction (HS-SPME) coupled to gas chromatography-mass spectrometry (GC-MS) was employed for analyzing the aroma components in Nanguo pear wine. HS-SPME was carried out at 4 different temperatures (20, 30, 40 and 50 ℃) in order to examine the effect of extraction temperature on the GC-MS analysis of the aroma components in Nanguo pear wine. The major aroma compounds identified in Nanguo pear wine extracted at 4 different temperatures were all esters and alcohols. Ethanol, ethyl acetate, 1-propanol, 2-methyl-, 1-butanol, 3-methyl-, 1-butanol, 2-methyl-, butanoic acid, ethyl ester, isoamyl acetate, 3-(methylthio)propanoic acid ethyl ester, phenylethyl alcohol, decanoic acid ethyl ester were all identified in Nanguo pear wine regardless of the HS-SPME temperature setting. The number of the kinds of aroma compounds identified in Nanguo pear wine extracted at 40 ℃ was the largest.

Key words: Nanguo pear wine, aroma composition, temperature, gas chromatography-mass spectrometry (GC-MS)
