  • Applications

    5-Ethyl-4-hydroxy-2-methyl-3(2H)-furanone (also known as homofuraneol or strawberry furanone) is a key flavor compound with a characteristic caramel, burnt-sugar and ripe-strawberry note; it is widely used in the food industry to enhance perceived sweetness and aroma depth in soft drinks, non-alcoholic beers, fruit juices, jams, hard candies, chocolate, baked goods, yogurts, ice creams, roasted coffee, instant tea, marinades and processed meat products; in fragrance and cosmetic formulations to provide warm sweet facets to perfumes, shampoos, shower gels, scented candles and room diffusers; in tobacco and vape liquids to recreate fruity top notes; and it serves as an analytical reference standard, a model compound for Maillard-reaction studies, a substrate for enzyme engineering toward biotechnological production of natural flavors, and even as a trace additive in post-harvest treatments to restore the aroma of frozen fruits.
