| Hazard Information | Back Directory | [Chemical Properties]
5-Decanolide is a flavor constituent
of many types of fruit, cheese, and other dairy products. It is a colorless,
viscous liquid with a creamy-coconut, peach-like aroma. | [Chemical Properties]
clear colorless to light yellow oily liquid | [Chemical Properties]
δ-Decalactone has an oily, peach odor and taste. | [Occurrence]
Reported found in rum, coconut, raspberry, apricot, bilberry, peach, strawberry, Swiss cheese, other cheeses,
butter, milk, milk powder, mutton fat, mango and nectarine. | [Uses]
Used in pharmaceutical preparations, feed additive, flavorings agent. Also used by food and flavor industries for its coconut fragrance and taste. It is also used as a reagent in the synthesis of (±)-Massoilactone (M197600); a chemical component with antibacterial activity found in volatile oils. | [Definition]
ChEBI: A delta-lactone that is 5-valerolactone substituted by a pentyl group at position 6. | [Preparation]
δ-Decalactone can be prepared by peracid oxidation of 2-pentylcyclopentanone.
(R)-δ-decalactone is obtained in high optical purity by starting from (R)-2-
pentylcyclopentanone . Hydrogenation or fermentation of
massoia lactone is also a practicable method to produce this
enantiomer.
A newer development for the preparation ofδ-decalactone describes a carboxylation
of 1-nonen-4-ol with carbon monoxide in the presence of a homogenous
palladium catalyst in an aqueous system. | [Aroma threshold values]
Detection: 100 ppb | [Taste threshold values]
Taste characteristics at 2 ppm: waxy, coconut, lactonic, fatty, creamy, nutty and fruity. | [Synthesis Reference(s)]
