構造式
1. Product Property
Ethyl maltol is a white crystalline powder with a sweet, caramel-like aroma. It is highly soluble in hot water, alcohol, and propylene glycol, but less soluble in cold water. The compound is stable under normal conditions but may degrade under strong light or high temperatures. It enhances sweetness and masks bitterness in food products, making it a valuable flavor enhancer.

3.適用範囲と使用方法
Ethyl maltol is widely used as a flavor enhancer in the food, beverage, and pharmaceutical industries. It is commonly added to baked goods, dairy products, candies, and soft drinks to improve sweetness and mask undesirable tastes. In pharmaceuticals, it is used to enhance the palatability of syrups and chewable tablets. The typical usage level ranges from 5 to 250 ppm, depending on the application. It is also used in tobacco and cosmetic products for its pleasant aroma.
4.パッケージと保管
Ethyl maltol is typically packaged in 1 kg, 5 kg, or 25 kg aluminum foil bags or HDPE containers to protect it from moisture and light. It should be stored in a cool, dry, and well-ventilated area, away from direct sunlight and heat sources. The shelf life is 24 months when stored under optimal conditions. Proper sealing is essential to maintain product quality and prevent contamination.
