一般描述
乙偶姻是一种丙烯酸衍生物。在光线和水分存在的情况下，它会转化成白色固体二聚体。由双乙酰还原形成。它是由乙醛合成的。
乙偶姻是一种挥发性化合物，广泛用于食品、香烟、化妆品、洗涤剂、化学合成、植物生长促进剂和生物防治。乙偶姻是在葡萄糖和其他可发酵碳源上生长的枯草芽孢杆菌的主要胞外产物。它有助于与酒精饮料相关的香气和味道。报道了利用酿酒酵母发酵生产乙偶姻。乙偶姻是天然存在于奶油食品，如啤酒，黄油和奶酪。已报告了双乙酰和乙偶姻的测定，以评价爆米花加工机构的工作场所接触度。
应用
- Role of Volatile Organic Compounds Produced by Kosakonia cowanii Cp1 during Competitive Colonization Interaction against Pectobacterium aroidearum SM2.: This study investigates the role of volatile organic compounds, including acetoin, produced by Kosakonia cowanii Cp1 in inhibiting Pectobacterium aroidearum SM2, highlighting the potential of acetoin in biocontrol applications (Mena Navarro et al., 2024).
- Chemical imitation of yeast fermentation by the drosophilid-pollinated deceptive trap-flower Aristolochia baetica (Aristolochiaceae).: The research explores how Aristolochia baetica mimics yeast fermentation, including the production of acetoin, to attract drosophilid pollinators, emphasizing acetoin′s role in plant-pollinator interactions (Rupp et al., 2024).
- Investigating the impact of various sorghum types on the key aroma compounds of Sichuan Xiaoqu Baijiu through application of the sensomics approach.: This study examines how different sorghum types influence the key aroma compounds, including acetoin, in Sichuan Xiaoqu Baijiu, demonstrating acetoin′s significance in food and beverage flavor profiles (Ma et al., 2024).
- Regulation of Tetramethylpyrazine Formation by the Phenolics-Fenton Coupled Redox Cycling System.: The research delves into the biochemical pathways regulated by acetoin in the formation of tetramethylpyrazine, providing insights into its role in flavor compound biosynthesis (Xu et al., 2024).
- Design of a synthetic enzyme cascade for the in vitro fixation of formaldehyde to acetoin.: This paper presents the development of a synthetic enzyme cascade to convert formaldehyde to acetoin, showcasing its potential in biotechnological applications for formaldehyde detoxification (Cui et al., 2024).
