product description

Product Description of Ethyl maltol CAS#4940-11-8

Ethyl maltol is a white crystalline substance melting at 90–91°C, featuring a rich sweet caramel aroma. Its flavor-enhancing strength is 4–6 times that of maltol. Multiple synthetic processes are available for its preparation. A typical route uses ethylfurfuryl alcohol as the raw material, which reacts with halogens to generate the intermediate 4-halo-6-hydroxy-2-ethyl-2H-pyran-3(6H)-one. The intermediate can be directly hydrolyzed in water without separation to obtain ethyl maltol. The compound has a unique, long-lasting sweet fruity fragrance. It delivers a sweet and fruity taste with a slight initial bitter-sour note that dissipates rapidly. Due to its far higher aroma intensity than maltol, it works excellently as a high-efficiency flavor enhancer.

Product Application of Ethyl maltol CAS#4940-11-8

Ethyl maltol acts as an efficient flavor and aroma enhancer, widely used in baked goods, beverages, and synthetic berry and citrus flavorings. It also masks unpleasant odors and tastes in tobacco, cough syrup, vitamins, cosmetics and saccharin-containing products. It is a white crystalline powder with a unique fruity fragrance and sweet taste, melting at 90°C. It is slightly soluble in water and propylene glycol, and easily soluble in alcohol and chloroform. It is prepared by chemical synthesis.
