中文摘要: 采用同时蒸馏萃取与溶剂辅助风味蒸发法萃取分析巴氏全脂乳的挥发性成分,用气相色谱-质谱联用(GCMS)对挥发性成分进行了分析。结果表明同时蒸馏萃取法以二氯甲烷为萃取溶剂时鉴定出8种成分,以乙醚为萃取溶剂时鉴定出6种成分;溶剂辅助风味蒸发法鉴定出8种,两种方法共计鉴定出14种挥发性成分,其中酸类8种、醛类1种、醇类2种、酯类2种、其它类1种,其中含量较大的有己酸、辛酸、癸酸、月桂酸、肉豆蔻酸等。
Abstract:Volatile compounds extracted by simultaneous distillation extraction(SDE)and solvent assisted flavor evaporation(SAFE)from pasteurized whole milk were analyzed by gas chromatography-mass spectrometry (GC-MS).In SDE and SAFE analysis,8 compounds were both identified with dichloromethane as extraction solvent respectively,while a total of 6 compounds were identified in the extraction of ethyl ether.Totally,14 volatile compounds were obtained by these two kinds of methods,including 8 fatty acids,1 aldehyde,2 alcohols,2 esters,and 1 other compound.The prominent compounds were hexanoic acid,octanoic acid,decanoic acid,lauric acid,myristic acid,etc.
