摘要:

通过对顶空固相微萃取-气相色谱-质谱法分析条件的优化及其对养殖大黄鱼鱼肉挥发性成分进行鉴定,以鱼肉中普遍存在且含量较高的物质(己醛、庚醛、雪松醇、葵醛、1-辛醇、辛醛、1-辛烯-3-醇、壬醛等)为参照对象,分析比较获得合适的萃取条件:CAR-PDMS萃取头(75μm)、样品体积8mL、NaCl质量浓度0.256g/mL、萃取温度60℃、萃取时间50min。结果表明:从养殖大黄鱼肉中检测出挥发性烃类、醛类、醇类、酯类、酮类、含氮含硫含氧及杂环类等共39种挥发性成分,各类成分分别占挥发性化合物总量的19.91%、16.50%、18.01%、38.20%、0.60%、6.78%。

Abstract:

The volatile flavor compounds in fresh large yellow croaker flesh were extracted by head space solid phase microextraction
(HS-SPME) technique and determined by gas chromatography-mass spectrometry (GC-MS). Based on the
abundance of ubiquity of fish flesh volatiles (hexanal, heptanal, cedrol, decanal, 1-octanol, octanal, 1-octen-3-ol and nonanal),
the optimum extraction conditions were determined as follows: CAR-PDMS extraction head (75 μm), sample
injection volume 8 mL, NaCl concentration 0.256 g/mL, extraction temperature 60 ℃, and extraction time 50 min. Totally
39 volatile flavor compounds were identified, including alkanes, aldehydes, alcohols, ester, ketones, and N-, S- or
O-containing compounds as well as heterocyclic compounds with relative concentration of 19.91%, 16.50%, 18.01%,
38.20%, 0.60% and 6.78%, respectively.

Key words: headspace-solid phase microextraction (HS-SPME), gas chromatography-mass spectrometry (GC-MS), large yellow croaker, volatile compounds
