Ethyl caprylate Usage And Synthesis

Description

Ethyl caprylate (ethyl octanoate) is a kind of fatty acid ester formed from caprylic acid and ethanol. It is a kind of natural fruit flavoring agent. It is usually included in the alcohol beverage. Among the main flavoring components of None-flavor liquor, the absolute content of ethyl caprylate is not high but its flavoring contributions is higher than ethyl acetate, ethyl lactate, and ethyl butyrate, only lower than ethyl caproate. Only small amount of ethyl caprylate could produce obvious fruit aroma in Nong-flavor liquor. However, excessive content of ethyl caprylate would inhibit the performance of other flavoring components.

Chemical Properties

CLEAR COLOURLESS LIQUID

Chemical Properties

Ethyl Octanoate is a liquid with a fruity, floral odor. It occurs in many fruits and alcoholic beverages and is used in fruit flavors.

Chemical Properties

Ethyl octanoate has a pleasant, fruity, floral odor (wine–apricot note)

Occurrence

Reported found in apple, apricot, orange juice, grapefruit juice, guava, pineapple, cheddar cheese, other cheeses, butter, beer, cognac, rum, whiskey, cider, grape wines, cocoa, coconut meat, passion fruit, mango, pawpaw and mastic gum leaf oil.

Uses

manufacture of fruit ethers; constituent of enanthic, cocoic, and cognac ethers.

Uses

Ethyl caprylate is a flavoring and fragrance agent.

Preparation

Usually prepared by esterification of caprylic acid with ethyl alcohol and sulfuric acid as catalyst; also by alcoholysis of coconut oil in the presence of HCl.

Definition

ChEBI: A fatty acid ethyl ester resulting from the formal condensation of octanoic acid with ethanol.

Aroma threshold values

Detection: 5 to 92 ppb

Taste threshold values

Taste characteristics at 5 ppm: waxy, fatty, aldehydic, coconut, creamy and dairy-like.

Safety Profile

Mddly toxic by ingestion. A skin irritant. Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes. See also ESTERS.

Carcinogenicity

Not listed by ACGIH, California Proposition 65, IARC, NTP, or OSHA.
