Beschreibung
γ-Nonalactone has a strong odor reminiscent of coconut and a fatty, peculiar taste. May be synthesized by reacting methylacry- late and hexanol in the presence of ditertiarybutyl peroxide; by condensation of undecylenic acid and malonic acid; by lactonizα- tion of nonenoic acid.
Chemische Eigenschaften
gamma-Nonanolactone occurs in many foods
and is a pale yellow liquidwith a coconut-like aroma. It has numerous applications,
similarly to those of ??-octalactone, in aroma compositions and perfumery.
Occurrence

Verwenden
(Gamma)-Nonalactone is a synthetic flavoring agent that is a colorless to yellow liquid of strong, coconut-like odor. It is soluble in most fixed oils, mineral oil, and propylene glycol. It is stable in acids and unstable in alkali and should be stored in glass, tin, or aluminum containers. It is used in coconut flavors and has application in gelatins, puddings, baked goods, candy, and ice cream at 11–55 ppm. It is also termed aldehyde c-18.

Allgemeine Beschreibung
γ-Nonanoic lactone is an oak lactone commonly found in wines aged in oak barrels. It is the main flavor component of coconut. γ-Nonanoic lactone is also a potential multi-species attractant lure for grain beetle pests.
Sicherheitsprofil
Moderately toxic by
ingestion. A skin irritant. Mutation data
reported. Combustible liquid. When heated
to decomposition it emits acrid smoke and
irritating fumes. See also ALDEHYDES.
