利用固相微萃取一气相色谱一嗅觉辨别法和风味值分析法对酶解奶油香精基料中特征风味组分进行研究.结果表明:嗅觉辨别法检测得到18种可被评价员嗅觉检测且与GC-MS分析结果对应的化合物;同时根据化合物在样品中的含量以及其相应的平均嗅闻阈值,分析了酶解产物中24种主要挥发性风味化合物的风味值.并且两种分析方法得到的特征风味化合物种类相同的有13种,但两种方法分析得到的同种风味组分在样品中的风味强度差别较大.综合气相色谱一嗅觉辨别法和风味值分析结果,酶解奶油香精基料中特征风味组分主要为:丁酸、己酸、辛酸、癸酸、己酸乙酯等.
利用固相微萃取一氣相色譜一嗅覺辨彆法和風味值分析法對酶解奶油香精基料中特徵風味組分進行研究.結果錶明:嗅覺辨彆法檢測得到18種可被評價員嗅覺檢測且與GC-MS分析結果對應的化閤物;同時根據化閤物在樣品中的含量以及其相應的平均嗅聞閾值,分析瞭酶解產物中24種主要揮髮性風味化閤物的風味值.併且兩種分析方法得到的特徵風味化閤物種類相同的有13種,但兩種方法分析得到的同種風味組分在樣品中的風味彊度差彆較大.綜閤氣相色譜一嗅覺辨彆法和風味值分析結果,酶解奶油香精基料中特徵風味組分主要為:丁痠、己痠、辛痠、癸痠、己痠乙酯等.

The solid-phase micro-extraction gas chromatograph olfactometry (SPME-GC/O) and the o- dour unit value (OUV) were applied in the major characteristic volatile compounds analysis of the lipolyzed cream. The result of SPME-GC/O showed that 18 volatile compounds could be detected both by the sensory panel and the GC-MS. Furthermore, based on the concentration of the volatile compounds of sample and their individual threshold, there were 24 possibly major characteristic volatile compounds evaluated by OUV. The result showed that most of the volatile compounds in sample were similar, while their flavor intensity was different. Combining the results of SPME-GC/O and OUV, the major characteristic volatile compounds of lipolyzed cream were identified as butanoic acid, hexanoic acid, octanoic acid, decanoic acid, and ethyl caproate.
