Acetoin is widely used in the food and beverage industry as a flavoring agent due to its buttery and creamy aroma. It is a key component in the production of dairy flavors, such as butter, cheese, and yogurt, enhancing the richness and authenticity of these products. In the fragrance industry, it is utilized to add a sweet, creamy note to perfumes and cosmetics. Additionally, acetoin serves as an intermediate in the synthesis of various chemicals, including pharmaceuticals and agricultural products. Its ability to act as a precursor in biochemical pathways also makes it valuable in microbial fermentation processes for producing other compounds.
