摘要 在应用顶空-固相微萃取(HS-SPME)和同时蒸馏萃取(SDE)与气质联用(GC-MS)法对精武鸭脖中的挥发性风味成分进行分离鉴定的前提下,采用不同的萃取头、有机溶剂对顶空-固相微萃取法和同时蒸馏萃取法进行优化,结果表明,顶空-固相微萃取法宜采用PDMS/DVB萃取头,同时蒸馏萃取法宜采用乙醚作为有机溶剂;2种方法共鉴定出68种风味化合物,其中烃类20种,醇类13种,醛类10种,酚类2种,酮类4种,酯类9种,醚类3种,酸类2种,其他化合物5种。 The volatile flavor compounds of Jingwu duck neck were isolated by headspace solid phase micro-extraction (HS-SPME) and simultaneous distillation extraction (SDE) and then identified by gas chromatography-mass spectrometry (GC-MS). Conditions of extraction fibers and organic solvents were optimized for combination of HS-SPME and SDE. The results showed that the optimum conditions were using PDMS/DVB extraction fiber and diethyl ether as organic solvent. Totally, 68 volatile flavor compounds were isolated and identified, including hydrocarbons (20 kinds), alcohols (13 kinds), aldehydes (10 kinds), phenols (2 kinds), ketones (4 kinds), esters (9 kinds), ethers (3 kinds), acids (2 kinds) and other compounds (5 kinds).
