- 介绍: 4-乙基苯酚 (4-EP) 是一种对位取代的酚类化合物。是红葡萄酒中重要的香气化合物之一。红葡萄酒中与 4-EP 有关的香味有“马皮”、“皮革”、“药用”、“烟熏”、“谷仓”、“动物”、“汗鞍”等。从p-香豆酸生产 4-EP 的合成培养基利用与葡萄酒生产相关的几个酵母菌种已有报道。在玻碳电极 (GCE) 上用伏安法研究了它的电活性中心和氧化途径。据报告,木质素的氢解形成 3.1% 的 4-EP。该方法有可能替代传统的石油化工合成路线。开发了一种基于分子印迹纳米颗粒选择性检测 4-EP 的传感器。研究了从软木中提取的聚苯胺 (PANI) 材料和木栓醇 (suberin) 对葡萄酒中 4-EP 的去除能力。4-乙基苯酚是一种挥发性苯酚。以 p -香豆酸为原料,采用含 蛇床子 ISA 1791 的合成介质合成。经鉴定,它是红葡萄酒中的一种芳香化合物。;4-Ethylphenol (4-EP) is a para-substituted phenolic compound. It is one of the important aroma compounds in red wine.The aroma associated with 4-EP in red wine has been described as ′′horsy′′, ′′leather′′, ′′medicinal′′, ′′smoky′′, ′′barnyard′′, ′′animal′′ and ′′sweaty saddle′′-like. Production of 4-EP from p-coumaric acid in synthetic media utilizing several yeast species associated with wine production has been reported. Its electroactive center and oxidation pathways have been studied by voltammetric techniques at a glassy carbon electrode (GCE). Hydrogenolysis of lignin has been reported to form 3.1% of 4-EP. This method may be a potential alternative to the conventional petrochemical route of its synthesis.A sensor based on the molecularly imprinted nanoparticles to selectively detect 4-EP has been developed. The ability of polyaniline (PANI) materials and suberin extracted from cork in removing 4-EP from wine has been investigated. 4-Ethylphenol is a volatile phenol. It has been synthesized from p-coumaric acid by employing a synthetic medium containing Dekkera bruxellensis ISA 1791.It has been identified as an aroma compound in red wine.
