2-phenylethanol, or 2-isobutylthiazole had higher odor units in the less preferred cultivars. Simulation of the odor of the selected tomato cultivars by preparation of aroma models and comparison with the corresponding real samples confirmed that all important fresh tomato odorants were identified, that their concentrations were determined correctly in all five cultivars, and that differences in concentration
使用香气
提取物筛选了三个鲜味(BR-139,FA-624和FA-612)和两个鲜味(R-144和R-175)的鲜温室番茄品种,它们的风味特征明显不同,它们的风味特征明显不同稀释分析(AE
DA)。根据AE
DA结果,使用气相色谱-质谱法(GC-MS)在这5个品种中选择了19种挥发物进行定量。化合物,例如1-

呋喃酮)在更优选的品种中具有较高的气味单位,而甲基,
苯乙醛,2-苯基
乙醇或
2-异丁基噻唑在较不优选的品种中具有较高的气味单位。通过制备香气模型并与相应的实际样品进行比较来模拟所选番茄品种的气味,证实了所有重要的新鲜番茄香味剂均已识别,在所有五个品种中均已正确确定了它们的浓度,并且浓度差异(尤其是浓度)有所差异。上述化合物可以区分它们,并引起差异偏爱。为帮助阐明关键气味的形成途径,将标记的前体添加到番茄中。证实了
