| 摘 要： | 以尼罗罗非鱼为原料,通过固相微萃取和气质联用仪对挥发性成分进行萃取和分离鉴定,测定尼罗罗非鱼肉的气味组成,并对暂养阶段的挥发性成分变化做初步分析。结果表明:从尼罗罗非鱼肉中检测出挥发性醛类、烷烃类、芳烃类、醇类、酯类和烯类等31种有效成分,其中含量由高到低依次为醛类、芳烃类和烷烃类,暂养初期和末期分别占挥发性化合物总量的36.97%、17.85%、20.70%和44.49%、34.65%、8.66%。暂养时间为8d时,辛醛和壬醛含量有明显的下降,有利于脱除不良风味;辛三烯和环己烯同时未检出,消除了不良气味的潜在因素;苯甲醛、苯环芳烃类物质含量相对于0d也有一定程度的增加,这有利于罗非鱼良好风味的形成。

| Abstract: | The volatile compounds in the muscle of Tilapia nilotica during 12 days of purging in autumn were extracted by solid phase micro-extraction(SPME) and analyzed by gas chromatography-mass spectroscopy(GC-MS).Totally 31 kinds of volatile compounds were isolated and identified including aldehydes,hydrocarbons,Kwai alkenes,aromatic hydrocarbons,alcohols,esters,terpenes,and others,in which aldehydes,aromatic hydrocarbons and hydrocarbons were the top three most abundant compounds,with a relative level to total vo... |
