摘要:

采用溶剂辅助风味蒸发法萃取原味酸牛奶挥发性成分,利用气相色谱-质谱联用法结合保留指数、标准品对照对挥发性成分进行定性分析,采用面积归一化法加邻二氯苯作内标定量,共鉴定出挥发性成分52 种,其中酸12 种、醛2 种、酮5 种、醇2 种、酯3 种、内酯2 种、烯烃4 种、烷烃17 种、其他5 种。其中,对酸牛奶风味影响较大的可能有乙酸、丁酸、己酸、辛酸、癸酸、9-癸稀酸、乙偶姻、2-壬酮、2-十一酮、壬醛、香兰素、3-甲基-2-丁烯-1-醇、十六硫醇、丁位癸内酯、丁位十二内酯等。

Abstract:

Volatiles in plain yogurt were extracted by solvent-assisted flavor evaporation (SAFE) and identified by gas
chromatography-mass spectrometry (GC-MS) by combination of their retention indices with those of standards. Area
normalization method was used for quantitative analysis and 1,2-dichlorobenzene was used as internal standard. A total
of 52 volatiles were identified, including 12 acids, 2 aldehydes, 5 ketones, 2 alcohols, 2 lactones, 3 esters, 4 olefins, 17
hydrocarbons, and 5 other compounds. The main volatile flavor constituents in yogurt included acetic acid, butanoic acid,
hexanoic acid, octanoic acid, n-decanoic acid, 9-decenoic acid, acetoin, 2-nonanone, 2-undecanone, nonanal, vanillin,
3-methyl-2-buten-1-ol, 1-hexadecanethiol, delta-decalactone, and delta-dodecalactone.

Key words: yogurt, solvent-assisted flavor evaporation (SAFE), gas chromatography-mass spectrometry (GC-MS), volatiles, retention indices, standards
