Beschreibung
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.
Chemische Eigenschaften
Ethyl octanoate has a pleasant, fruity, floral odor (wine–apricot note)
Chemische Eigenschaften
Ethyl Octanoate is a liquid with a fruity, floral odor. It occurs in many fruits and alcoholic beverages and is used in fruit flavors.
Chemische Eigenschaften
CLEAR COLOURLESS LIQUID
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.
Verwenden
Ethyl caprylate is a flavoring and fragrance agent.
Verwenden
Ethyl octanoate, found in Burgundy wine, was used to study its partition co-efficient in water in model wine using the headspace method.
Verwenden
manufacture of fruit ethers; constituent of enanthic, cocoic, and cognac ethers.
Definition
ChEBI: A fatty acid ethyl ester resulting from the formal condensation of octanoic acid with ethanol.
synthetische
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.
Aroma threshold values
Detection: 5 to 92 ppb
Taste threshold values
Taste characteristics at 5 ppm: waxy, fatty, aldehydic, coconut, creamy and dairy-like.

Allgemeine Beschreibung
Ethyl octanoate is a powerful odourant found in mead (a traditional drink that contains alcohol).
Flammability and Explosibility
Not classified
Sicherheitsprofil
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.
Stoffwechsel
Aliphatic esters including ethyl caprylate are thought to be readily hydrolysed to the corresponding alcohol and acid, which are then further metabolized (Fassett, 1963). Oral adminis tration of ethyl caprylate to rats produced a ketonuria twice as great as that from acetoacetate, indicating the formation of two fragments for the production of ketone bodies, and it was suggested that caprylic acid was probably broken down by a process involving multiple alternate oxidation (Deuel, Hallman, Butts & Murray, 1936).
