中文摘要: 采用顶空固相微萃取法提取猕猴桃果酒中香气物质,通过单因素试验优化固相微萃取条件,并采用气相色谱-质谱联用法分析所收集8种猕猴桃果酒中的香气组分。结果表明:30 μm PDMS微萃取头适用于猕猴桃果酒香气物质分析,最佳条件为萃取时间40 min、萃取温度40℃、氯化钠浓度0.2 g/mL。采用气相色谱-质谱联用法从8种猕猴桃果酒中主要检测到辛酸乙酯、癸酸乙酯和正己酸乙酯等酯类物质,此外含有大量醇类、酸类和酚类物质,不同品种猕猴桃果酒中各主要香气成分种类和相对含量有明显差异。
Abstract:The aromatic components of kiwi fruit wines were extracted using the headspace solid-phase microextraction method,which was optimized by a single-factor test.Gas chromatography-mass spectrometry was used to analyze the aroma components in the eight kiwi fruit wines.The optimal method was applied using a 30 μm polydimethylsiloxane extraction head at an extraction time of 40 min,extraction temperature of 40 ℃and sodium chloride concentration of 0.2 g/mL.Results showed that the main aromatic ingredients of kiwi fruit wine were esters such as ethyl octanoate,ethyl decanoate and ethyl n-hexanoate.They were also found to contain many types of alcohols,acids and phenols.Significant differences were observed between the types and relative contents of the main aroma components in the kiwi fruit wine of different varieties.
