Chemical Properties
γ-Decalactone has a pleasant, fruity, peach-like odor.
Chemical Properties
clear colourless to pale yellow liquid
Chemical Properties
gamma-Decalactone is present in a wide
variety of foods and is an almost colorless liquid with an intensely fruity odor,reminiscent of peaches. It is used in perfumery for heavy, fruity flower odors and
in aroma compositions, particularly peach flavors.
Occurrence
Reported found in peach, apricot and strawberry aroma. Also reported in butter, milk, beer, rum, red and white
wine, mango, bilberry, plums, prunes, guava, peach, strawberry fruit and cheeses.
Uses
γ-Decalactone may be used as an analytical reference standard for the quantification of the analyte in fruit beverages using different chromatography techniques.
Preparation
Naturalγ-decalactone is produced biotechnologically starting from ricinoleic
acid, which is degraded by β-oxidation to 4-hydroxydecanoic acid, which
lactonizes at lower pH to yield γ-decalactone
Definition
ChEBI: Gamma-decalactone is a gamma-lactone that is oxolan-2-one substituted by a hexyl group at position 5. It has a role as a flavouring agent, a food additive and an anticonvulsant. It is a gamma-lactone and a tetrahydrofuranone.
