Cas no 4940-11-8 (Ethyl maltol)
Ethyl maltol (C?H?O?) is a synthetic flavor enhancer and sweetening agent, chemically related to maltol but with approximately 4–6 times the potency. It is widely used in food, beverage, and fragrance industries due to its ability to impart a sweet, caramel-like aroma and enhance overall flavor profiles. Ethyl maltol exhibits excellent stability under high temperatures, making it suitable for baked goods and thermally processed products. Its low odor threshold ensures effectiveness at minimal concentrations. The compound is also employed in pharmaceuticals and tobacco to mask bitterness. Ethyl maltol is generally recognized as safe (GRAS) by regulatory authorities when used within specified limits.
