Chemical Properties Maltol occurs in pine needles and the bark of young larch trees. It is produced when cellulose or starch is heated and is a constituent of wood tar oils. It forms crystals (mp 162–164°C) with a caramel-like odor, reminiscent of freshly baked cakes.
Occurrence Reported found in the bark of young larch trees (Pinus larix), pine needles (Abies alba), chicory, wood tars and oils, and roasted malt. Also reported found in wheat and rye bread, milk, butter, smoked pork, beer, cocoa, coffee, roasted barley, filberts, peanuts, soybean, beans, tamarind, licorice, sake, malt, dried bonito, clam and cocoa liquor.
