The Uses of ETHYL SORBATE

Ethyl Sorbate is a synthetic flavoring agent that is a moderately sta- ble, light yellow liquid of fruity odor. it should be stored in glass or tin containers. it is used in flavors such as pineapple, papaya, and passion fruit with applications in ice cream, beverages, candy, and baked goods at 6–18 ppm. it is also termed ethyl-2,4-hexadienoate.

The Uses of ETHYL SORBATE

The addition of chlorine and bromine to ethyl sorbate (la) gave 1, 2-and 1, a-dihalo products derived from attack of the halogen. Chlorination of la under ionic conditions proceeds through a tightly bridged chloronium ion intermediate.

Preparation

By reacting gaseous HCl with a solution of sorbic acid in ethyl alcohol, or by direct esterification by reaction of sorbyl chloride with absolute ethyl alcohol.

Definition

ChEBI: Ethyl sorbate is a fatty acid ester obtained by formal condensation of the carboxy group of sorbic acid and the hydroxy group of ethanol. It has a role as a metabolite. It is functionally related to a sorbic acid.

Taste threshold values

Taste characteristics at 30 ppm: fruity, sweet, green, pineapple, tutti fruity-like with juicy tropical nuance.

General Description

Ethyl sorbate is an active compound for electroantennographic detection.

Synthesis

Prod.: by direct esterification of Ethanol with Sorbic acid, e.g. under azeotropic conditions. The acid is obtained from Crotonaldehyde plus MaIonic acid.
