Ethyl caprate Usage And Synthesis

Description

Ethyl caprate (also known as ethyl decanoate) is the ethyl ester form of caprate. It is a kind of product during the fermentation process of winemaking. It also exists in the essential oils of many kinds of natural fruits. It can be used as a common flavoring agent and food spices.

Chemical Properties

Ethyl decanoate has a fruity odor reminiscent of grape (cognac). It has been also reported to have an oily, brandy-like odor.

Chemical Properties

clear colourless liquid

Occurrence

Reported found in cognac, apple, banana, cherry, citrus, grape, melon, pear, pinapple, and more.

Uses

Ethyl Decanoate, is a fatty acid ester formed from capric acid and ethanol. It is a volatile ester produced during the fermentation in winemaking. It can also be used as a flavor and fragrance ingredients.

Uses

manufacture of wine bouquets, cognac essence.

Definition

ChEBI: Ethyl decanoate is a fatty acid ethyl ester of decanoic acid. It has a role as a metabolite. It is a fatty acid ethyl ester and a decanoate ester.

Preparation

Ethyl decanoate is prepared by esterification of decanoic acid and ethyl alcohol in the presence of HCl or H2SO4.

Aroma threshold values

Detection: 8 to 12 ppb

Taste threshold values

Taste characteristics at 20 ppm: waxy, fruity, sweet apple.

General Description

Ethyl decanoate has ethereal, fruity, aromatic note that is considered to be essential for a fine wine flavor.

Safety Profile

A skin irritant. Combustible liquid when exposed to heat or flame; can react with oxidizing materials. When heated to decomposition it emits acrid smoke and irritating fumes. See ESTERS and ETHERS
