4-Dodecanolide Chemical Properties,Usage,Production

Chemical Properties

γ-Dodecalactone has a fatty, peachy, somewhat musky odor and buttery, peach-like flavor

Occurrence

Reported found in apricot, cooked pork, milk products, peach, bilberry, guava fruit, papaya, pineapple, fresh blackberry, strawberry, celery leaves and stalks, celery root, blue cheeses, cheddar cheese, Swiss cheese, meats, beer, rum, mushrooms, plum brandy, quince, chervil, naranjilla fruit and other natural sources

Uses

4-Dodecanolide was one of the organic compounds from meat charbroiling operations studied. Finds some use in perfume compositions for fatty-fruity topnotes and long tenacity, e.g., in heavy floral fragrances. It is also used in combination with newer synthetic musks to produce exceptional tenacity and lasting sweetness in powdery and floral types. Used in flavour compositions, mainly in Butter, Butterscotch, Coconut, Tutti-frutti, Maple, Nut, Peach, Pineapple, etc.

Preparation

From 1-dodecen-12-oic acid with H2SO4 at 90°C; from 4-hydroxydodecanoic acid by lactonization; also from methylacrylate and octanol

Definition

ChEBI: Xi-Dihydro-5-octyl-2(3H)-furanone is a gamma-lactone.

Aroma threshold values

Detection: 7 ppb; aroma characteristics at 1.0%; sweet, creamy, fruity peach and apricot, lactonic, with dairy waxy and fatty nuances.

Taste threshold values

Taste characteristics at 1 to 10 ppm: sweet, fruity peach, milky fatty and waxy with a pulpy fruity mouthfeel.
