Chemische Eigenschaften
δ-Decalactone has an oily, peach odor and taste.
Chemische Eigenschaften
clear colorless to light yellow oily liquid
Chemische Eigenschaften
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.
Occurrence
Reported found in rum, coconut, raspberry, apricot, bilberry, peach, strawberry, Swiss cheese, other cheeses, butter, milk, milk powder, mutton fat, mango and nectarine.
Verwenden
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.
synthetische
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.
