Application:	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 ).
General description:	Acetoin is a volatile flavor compound with a buttery odor and flavor. It is mainly found in Kefir and yogurt. Acetoin is used as a flavoring agent in butter, milk, shortening and baked goods.
