Acetoin, also known as 3-hydroxybutanone, is an organic compound commonly used in the food and fragrance industries for its pleasant, buttery scent. Naturally present in products like butter, yogurt, and honey, it enhances the rich, savory flavors of these foods. In food production, acetoin serves as a vital flavoring agent, improving the taste of baked goods, dairy products, and sweets. In the fragrance industry, it adds warmth and complexity to various blends. Acetoin also plays a significant role in biochemical research as a metabolic intermediate in fermentation processes. Its versatility and sensory appeal make it a popular choice in food science and aroma development.
