Product Details

Ethyl maleic-anhydride.html">maltol (CAS#4940-11-8) appears as white crystalline powder with a melting point of 90–91°C. It emits an intensely sweet caramel‑like aroma, and its flavoring potency is 4 to 6 times stronger than maltol. Various synthetic routes are available for its production. In a typical one‑pot synthesis, α‑ethylfurfuryl alcohol undergoes halogenation to form 4‑halo‑6‑hydroxy‑2‑ethyl‑2H‑pyran‑3(6H)‑one, which can be directly hydrolyzed in aqueous solution to yield ethyl maltol without isolation.

Ethyl maltol features a persistent sweet, fruity odor and a pleasant sweet‑fruity taste with an initial mild bitter‑tart note, followed by rapid flavor fading. Its flavor enhancement effect is 4–6 times more powerful than maltol.Ethyl maltol

Product Application

Ethyl maltol serves as a highly effective flavor and fragrance booster in food products, including baked goods, drinks, and artificial berry or citrus flavors. It also reduces unpleasant off‑notes in tobacco, cough syrups, vitamins, cosmetics, and saccharin‑containing items.

As a food additive, ethyl maltol is a white crystalline material with a characteristic odor and sweet fruity taste. It melts at approximately 90°C, is slightly soluble in water and propylene glycol, and dissolves in alcohol and chloroform. It is manufactured via chemical synthesis.
