Ethyl valerate Usage And Synthesis
AromaPowerful and diffusive, ethereal-fruity, Apple-like odor with a remote resemblance to Pineapple. Esters with traces of free acids will show this very perceptibly in the odor, not so conspicuously in the flavor (in aqueous media). Sweet and somewhat pungent-fruity, AppleIike, almost "gassy"-ethereal taste. In extreme dilution, the taste is merely sweet fruity.
Chemical Propertiesclear colorless liquid
Chemical PropertiesEthyl valerate has a fruity odor suggestive of apple
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.
DefinitionChEBI: Ethyl pentanoate is a fatty acid ester.
PreparationBy refluxing valeric acid and ethyl alcohol in the presence of concentrated H2SO4.
Aroma threshold valuesDetection: 1.5 to 5 ppb
Taste threshold valuesTaste characteristics at 30 ppm: fruity, strawberry, sweet, estry, fruity, pineapple, and tropical fruit.
