as sulfides, thiols, mercaptoaldehydes and mercaptoketones, which are derived from the Maillard reaction. Meanwhile, lipid oxidation results in the formation of unsaturated aldehydes, such as alkenals and alkadienals. Families of thiazoles and 3-thiazolines were found in the extracts. Two novel 3-thiazolines (5-ethyl-2,4-dimethyl-3-thiazoline and 2-ethyl-4,5-dimethyl-3-thiazoline) which may also contribute
消费者格局向纯素食、素食和弹性饮食的转变,在从植物性替代品中创造肉类香气方面带来了前所未有的挑战。因此,寻找潜在的纯素解决方案引起了人们对正宗肉类风味特征的重新兴趣。为了更好地了解煮牛肉和煮鸡肉之间的定性气味差异,使用 Likens-Nickerson 同时蒸馏-萃取 (SDE) 分离香气提取物,明确选择是因为样品的原位加热有助于捕获香气中间体在烹饪过程中,从而模仿肉汤和炖菜的烹饪。然后通过气相色谱-质谱 (GC-MS) 和 GC-嗅觉 (GC-O) 分析提取物。本研究中鉴定出的大部分挥发物是含硫化合物,如硫化物、硫醇、巯基醛和巯基酮,它们来源于美拉德反应。同时,脂质氧化导致不饱和醛的形成,例如烯醛和二烯醛。在提取物中发现了噻唑类和 3-噻唑啉类。在这项工作中鉴定了两种新的 3-噻唑啉(5-乙基-2,4-二甲基-3-噻唑啉和 2-乙基-4,5-二甲基-3-噻唑啉),它们也可能有助于产生肉味
