Description and Uses
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 may be used as an analytical reference standard for the quantification of the analyte in the following:
Soy sauce using liquid chromatography coupled to mass spectrometry (LC–MS).
Liquid food samples using gas chromatography with flame ionization detection (GC-FID).
