摘要: 采用同时蒸馏萃取法提取燕麦炒米香味物质,然后利用气相色谱-质谱技术对提取的燕麦炒米香味物质进行检测和成分分析。结果共分离出86种成分,鉴定出58种,占香味物质总峰面积的85.23%。主要成分有Z,Z-9,12-十八碳二烯酸(20.01%)、E,E-2,4-癸二烯醛(7.15%)、十六烷酰胺(5.30%)、二十烷(4.38%)、十六烷(4.17%)、乙酸乙酯(3.52%)、2,6-二甲基吡嗪(3.03%)、3-乙基-2,5-二甲基-吡嗪(2.96%)、己醛(2.65%)、2-乙基-5-甲基吡嗪(2.64%)、乙酸丁酯(2.39%)、1-戊醇(2.11%)

Abstract: Aroma components were extracted from fried oat by simultaneous distillation and extraction (SDE), and analyzed by gas chromatography-mass spectroscopy (GC-MS). A total of 86 components were separated. Of them, 58 were identified, accounting for 85.23% of total peak area. The major components were Z,Z-9,12-octadecadienoic acid (20.01%), E,E-2,4-decadienal (7.15%), hexadecanamide (5.30%), eicosane (4.38%), hexadecane (4.17%), ethyl acetate (3.52%), 2,6-dimethyl-pyrazine (3.03%), 3-ethyl-2,5-dimethyl-pyrazine (2.96%), hexanal (2.65%), 2-ethyl-5-methyl-pyrazine (2.64%) and 1-pentanol (2.11%).
