| 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. | Synthesis Reference(s) | Canadian Journal of Chemistry, 58, p. 2271, 1980 DOI: 10.1139/v80-365 The Journal of Organic Chemistry, 54, p. 4848, 1989 DOI: 10.1021/jo00281a029 | General Description | Ethyl 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. |
