• Uses: Ethyl Maltol is an extract from medicinal plants such as P. Incarnata and can be used as an anticonvulsant, acting as a depressant, and on motor activity. Ethyl Maltol is a flavoring agent that is a white, crystalline powder. it has a unique odor and a sweet taste that resembles fruit. the melt- ing point is 90°c. it is sparingly soluble in water and propylene gly- col and soluble in alcohol and chloroform. it is obtained by chemical synthesis. Flavor and fragrance enhancer in foods, especially baked goods, beverages, and synthetic berry and citrus flavorings; minimizes undesirable flavors in tobacco products, cough syrup, vitamins, cosmetics, and saccharin-containing products.
