General description
4-乙基苯酚(4-EP)是对位取代的酚类化合物。它是红酒中一种重要的芳香物质。红酒中与4-乙基苯酚相关的风味形容是′′马厩味′′、′′皮革味′′、′′药味′′、′′烟味′′、′′谷仓场味′′、′′动物味′′和′′汗渍马鞍味′′。据研究报告，葡萄酒生产相关的多种酵母在合成培养基中可以对香豆酸为底物生成4-乙基苯酚。
Application
- 模型系统中挥发性酚类物质在橡木/葡萄酒界面的吸附行为：这项研究探索了 4-乙基苯酚与葡萄酒陈酿过程中橡木之间的相互作用，有助于了解挥发性酚类物质的吸附及其对葡萄酒风味的影响（Barrera-García 等人，2006 年）。
