Applications · 4 items

OccurrenceReported found in apples, bananas, guava, strawberry, cheeses, rum, whiskey, cider, sherry, grape wines, cocoa, coffee, honey and passion fruit, apricot, guava fruit and pineapple.

UsesEthyl valerate is widely used in flavor compositions, mainly for Apple imitations, but also for Apricot, Peach and in Butter and Nut complexes. Its power is utilized in the "Tutti-frutti" type of flavor for chewing gum, and it is occasionally used in tobacco flavoring. Concentrations vary from 5 to 15 ppm in the finished product, and up to 250 ppm in chewing gum.

UsesEthyl valerate has wide applications in the areas of food, pharmaceuticals and cosmetics industries.

General DescriptionEthyl valerate is also known as the green apple flavor. Microwave spectrum of ethyl valerate, observed by molecular beam Fourier transform microwave spectroscopy, has been reported.

Preparation methods

PreparationBy refluxing valeric acid and ethyl alcohol in the presence of concentrated H2SO4.
