Use
Levulinic acid has a tart, whiskey taste. It may be synthesized by the action of more or less concentrated HCL on sucrose, glucose, or fructose; hence, its reported presence in caramels.levulinic acid is used for calcium levulinate in pharmaceuticals, as esters in solvents and plasticizers, and for making valerolactone. As its uses expand, it will probably be made from cellulosic wastes. Mesitonic acid, a homolog of levulinic acid is obtained by boiing mesityl oxide with KCN.
