extract (AGE) has been recently characterized as a complexity of seasoning-like, metallic, fatty, and acidic notes; most of the important aroma compounds were identified in a previous study. Besides the 25 previously identified aromas of AGE, several of the odor compounds that contribute to the acidic notes were isolated and identified using various analytical techniques, including gas chromatography
老化大蒜提取物(AGE)的香气最近被表征为具有类似调味料,金属,脂肪和酸性的风味。大多数重要的香气化合物是在先前的研究中鉴定出来的。除了先前确定的25种AGE香气之外,还使用各种分析技术分离和鉴定了一些有助于酸性成分的气味化合物,包括气相色谱仪和嗅觉监测系统(GC-O),准确而高效的制备方法。 GC系统,GC–MS分析和感官评估。鉴定的香气包括:2,4-二甲基-1,3-二硫杂环戊烷,2,5-二甲基-1,4-二硫杂环丁烷和2,6-二甲基-1,4-二硫杂环丁烷。有趣的是,AGE包含这些成分中每一个的所有立体异构体。
