摘要:

以酿酒酵母XR、D254、VR、VL1发酵的甜瓜酒为试材,采用顶空固相微萃取和气相色谱-质谱联用技术分别对其进行香气成分分析。结果表明:4 种不同酵母发酵酒样共鉴定出86 种香气成分,包括酯类19 种、醇类29 种、酸类12 种、醛酮类17 种、烯烃类2 种、萜烯类4 种、酚类3 种,其中相同成分有35 种。根据定量结果和气味活度值判断出主要香气贡献物有12 种。通过主成分分析和感官评价综合判断,酵母VL1酿造酒样香气浓郁、协调,品质最佳,是适合甜瓜酒酿造的优良菌株。

Abstract:

The aromatic compositions of sweet melon wines fermented with four different wine yeast strains, i.e., XR, D254,
VR and VL1, respectively, were analyzed by headspace solid-phase micro extraction (HS-SPME) and gas chromatographymass
spectrometry (GC-MS). The results showed that 86 flavor compounds were identified, including 19 esters, 29
alcohols, 12 acids, 17 aldehydes and ketones, 2 alkenes, 4 terpenes and 3 phenols. Besides, 35 components were common
to the four wines. Quantitative analysis and evaluation of odor activity value (OAV) indicated that 12 components made
great contribution to the aroma of sweet melon wines. Through principal component analysis and sensory evaluation, it is
concluded that wine yeast strain VL1 is the most suitable strain for making sweet melon wine having the best quality with
elegant aroma.
