Delta Decalactone is naturally found in coconut and raspberry. It appears yellow transparent liquid with fruity and creamy odor.

Delta-Decalactone can be produced by the aldol reaction of cyclopentanone and valeraldehyde or the free radical addition reaction of Ditert-butyl peroxide and Cyclopentanone. It is commonly used as a flavoring and fragrance agent of daily chemical products and the main flavor compound in skim milk powder to create coconut-like flavor.
