Summary

这里介绍的是一种利用溶剂辅助风味蒸发和溶剂萃取,然后气相色谱-质谱法富集和分析茶提取物挥发性成分的方法,该方法可应用于所有类型的茶叶样品。

Transcript

我们探索味道和香气的分子基础,专注于来自茶树植物的茶产品。我们的目的是表征风味分子并研究影响茶感官属性的生化过程。分析茶香需要从茶样的复杂基质中分离和富集浓度非常低的挥发物。

样品制备方法通常是最大的挑战,对于获得有效数据至关重要,从而得出有意义的研究结论。通过对香气形成的系统研究,我们成功地确定了表观茉莉酸甲酯是负责茶叶兰花状香气的关键化合物。我们还表征了四种不同白茶品种的香气。

与常用的茶香制备方法不同,SAFE技术从茶叶输液中提供透明的挥发性馏出物,不含非挥发性化合物。香气化合物可以通过溶剂萃取轻松富集。最重要的是,获得的香气浓缩物的气味特征与原始样品的气味特征非常相似。

所提出的方法有助于各种研究目标,例如了解香气从茶树到茶杯的演变,研究影响感官生态学的特定分子的化学性质,表征茶香气以指导植物栽培,工艺改进,质量控制和创造新的风味。
