Kemialliset ominaisuudet

kirkas väritön tai vaaleankeltainen öljyinen neste

Kemialliset ominaisuudet

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.

Kemialliset ominaisuudet

δ-Decalactone has an oily, peach odor and taste.

Esiintyminen

Reported found in rum, coconut, raspberry, apricot, bilberry, peach, strawberry, Swiss cheese, other cheeses, butter, milk, milk powder, mutton fat, mango and nectarine.

Valmistelu

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.

Määritelmä

ChEBI: A delta-lactone that is 5-valerolactone substituted by a pentyl group at position 6.

Aromikynnysarvot

Tunnistus: 100 ppb

Makukynnysarvot

Taste characteristics at 2 ppm: waxy, coconut, lactonic, fatty, creamy, nutty and fruity.

Kemiallinen synteesi

From hexylethylene oxide and sodium malonic ester; also from decanoic acid.
