摘要
分别以乙醚和二氯甲烷为溶剂,用同时蒸馏萃取法,结合气相-质谱联用技术分析了四川郫县豆瓣酱的挥发性香成分,并对萃取时间进行了优化,确定了较佳的时间分别为乙醚2h、二氯甲烷3h。通过GC-MS检测,两种溶剂萃取一共检测出56种化合物,含量较高的化合物有3-甲基丁醇、糠醛、苯乙醛、4-乙基苯酚、4-乙基-2-甲氧基苯酚、乙酸、十二酸、十四酸、十六酸、9,12-十八碳二烯酸、十四酸乙酯、十六酸乙酯、9,12-十八碳二烯酸甲酯、油酸乙酯、十八碳酸乙酯等。
Flavor components of pea sauce from Pixian in Sichuan Province were analyzed by GC-MS combining with simultaneous distillation- extraction (SDE) .The time of SDE was optimized as the following : C4 H10O 2h, CH2 Cl2 3h.Fifty-six compounds were identified altogether by GC-MS. The major components were 3-methyl buanol, furfural, benzeneacetaldehyde, 4 - ethyl phenol, 4 - ethyl - 2 - methoxyl phenol, acetic acid, dodecanoic acid, tetradecanoic acid, hexadecanoic acid, ethyl undecanoate, ethyl tetradecanoate, ethyl hexadecanoate, methyl 9, 12-Octadecandienoate,linoleic acid ethyl ester,ethyl octadecanoate,and so on.
