clear yellowish liquid | [Chemical Properties]
Ethyl levulinate has an ethereal, fruity, green, sweet, pineapple, apple, rhubarb odor.
| [Occurrence]
Reported found in white bread, roasted onion, wheat bread, cognac, malt whiskey, grape wines, cocoa, bilberry
wine, Bourbon vanilla and cherimoya (Annona cheremolia Mill.). | [Definition]
ChEBI: Ethyl levulinate is an oxo carboxylic acid. | [Preparation]
Usually obtained by direct esterification of levulinic acid with ethanol and H2SO4 in benzene or in toluene; also in the
presence of HCI in ethanol; other methods starting from glucose, fructose and others are of less importance. | [Taste threshold values]
Taste characteristics at 40 ppm: fruity, green, waxy and melon. | [Synthesis Reference(s)]
