Delta decalactone Usage And Synthesis

Chemical Properties	clear colorless to light yellow oily liquid
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	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.
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.
Definition	ChEBI: A delta-lactone that is 5-valerolactone substituted by a pentyl group at position 6.
Aroma threshold values	Detection: 100 ppb
Taste threshold values	Taste characteristics at 2 ppm: waxy, coconut, lactonic, fatty, creamy, nutty and fruity.
Chemical Synthesis	From hexylethylene oxide and sodium malonic ester; also from decanoic acid.
