Maltol is a naturally occurring organic compound that is found in the bark of larch trees, pine needles, and roasted malt. Commercially it is produced by the extraction of larch trees, or by the roasting of malt, or produced by heating lactose and maltose. It produces a white crystalline powder that is very soluble, and has a distinct caramel/butterscotch smell. It is used as a flavour enhancer in food, especially in breads and cakes.http://www.creative-enzymes.com/product/Maltol_475.html
