Ethyl valerate Usage And Synthesis

Aroma

Powerful 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 Properties

clear colorless liquid

Chemical Properties

Ethyl valerate has a fruity odor suggestive of apple

Occurrence

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

Uses

Ethyl 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.

Uses

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

Definition

ChEBI: Ethyl pentanoate is a fatty acid ester.

Preparation

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

Aroma threshold values

Detection: 1.5 to 5 ppb

Taste threshold values

Taste characteristics at 30 ppm: fruity, strawberry, sweet, estry, fruity, pineapple, and tropical fruit.
