Ethyl Maltol
Broad Flavor Application: Ethyl maltol is commonly added to foods and beverages for its ability to intensify sweetness and enrich overall taste, making products more appealing.
Stable Taste Profile: In aqueous solutions, it retains its characteristic sweet and aromatic notes, ensuring flavor consistency throughout processing and storage.
Excellent Solubility: Readily dissolves in ethanol and other organic solvents, which allows easy incorporation into baked goods, confectionery, drinks, and other formulations.
High-Grade Crystalline Form: Supplied as a refined crystalline material, ethyl maltol provides reliability and precision for food flavoring systems.
Ethyl maltol is a chemically synthesized flavor enhancer that appears as a white crystalline powder with a characteristic fragrance and a sweet, fruity taste. It has a melting point of approximately 90 °C, dissolves readily in alcohol and chloroform, shows limited solubility in water and propylene glycol, and is widely valued for its strong flavoring properties.
