摘要: 采用固相微萃取和气相色谱-质谱联用技术,研究传统鱼汤烹制过程中挥发性成分的变化。草鱼肉块经油煎后与生姜、大蒜混合水煮制作鱼汤,煮制分为3 个时间段,0~10 min鉴定出挥发性化合物46 种,其中萜类20 种、芳香族9 种、醛类5 种、酮类2 种、醇类3 种、呋喃类3 种、含硫化合物3 种、其他1 种;11~20 min鉴定出挥发性化合物43 种,其中萜类22 种、芳香族3 种、醛类4 种、酮类1 种、醇类5 种、呋喃类2 种、含硫化合物4 种、其他2 种;21~30 min鉴定出挥发性化合物53 种,其中萜类21 种、芳香族5 种、醛类11 种、酮类3 种、醇类5 种、呋喃类2 种、含硫化合物3 种、其他3 种。这些化合物当中,萜和含硫化合物来源于生姜和大蒜,主要形成于煮制的初始阶段且含量在煮制过程中不断下降;醛、醇、酮等化合物主要由脂肪酸氧化形成,且在煮制过程中种类不断丰富,含量逐渐增加。油煎和调料添加是鱼汤风味化合物形成的主要原因,煮制是挥发性风味化合物种类不断丰富和含量平衡的过程。

Abstract: Changes in volatile compounds during the preparation of traditional Chinese grass carp soup were analyzed by solid phase micro-extraction coupled with gas chromatography-mass spectrometry (SPME-GC-MS). Grass carp soup was prepared by cooking fried-fish-fillets with ginger and garlic. A total of 46 volatile compounds, including 20 terpenes, 9 aromatic compounds, 5 aldehydes, 2 ketones, 3 alcohols, 3 furans, 3 sulphur-containing compounds, and one other compound, were identified by GC-MS during the first 10 min of cooking, 43 volatiles (22 terpenes, 3 aromatic compounds, 4 aldehydes, 1 ketones, 5 alcohols, 2 furans, 4 sulphur-containing compounds, and 2 other compounds) were detected during 11–20 min, and 53 volatiles, including 21 terpenes, 5 aromatic compounds, 11 aldehydes, 3 ketones, 5 alcohols, 2 furans, 3 sulphur compounds, and 3 other compounds, were found during 21–30 min. Among these, terpene and sulphur-containing compounds, which were derived from ginger and garlic, respectively, were formed during 0–10 min of cooking and decreased during 11–30 min, while aldehydes, ketones, and alcohols were resulted from the oxidation of lipids and their concentrations were increased during cooking. It could be concluded that flavor volatile compounds in fish soup were formed after frying or derived from spices, and were enriched and balanced during cooking.

Key words: grass carp soup, cooking, solid phase micro-extraction (SPME), gas chromatography-mass spectrometry (GC-MS), volatile compound changes
