General description

Levulinic acid (LA), is a biogenic product of hexose acid hydrolysis, produced from renewable or bio-based resources. LA is reported to react with a variety of compounds to result in products, which are widely used in pharmaceuticals, personal care products, electronics, plasticizers, antifouling compounds, fuels, solvents, polymers, anti-freeze agents, batteries, coatings, biologically active materials, corrosion inhibitors, adsorbents, etc. LA is also employed as a chemical intermediate in the production of biodegradable polymers, fuel extenders, herbicides, flavors, antibiotics and useful 5-carbon compounds.
This substance is listed on the positive list of the EU regulation 10/2011 for plastics intended to come into contact with food. Find all available reference materials for compounds listed in 10/2011 here

Application

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).

Yeast has long been considered the microorganism of choice for second-generation bioethanol production due to its fermentative capacity and ethanol tolerance. However, tolerance toward inhibitors derived from lignocellulosic materials is still an issue. Flocculating yeast strains often perform relatively well

The robust supramolecular structure of biomass often requires severe pretreatments conditions to produce soluble sugars. Nonetheless, these processes generate some inhibitory compounds (i.e. furans compounds and aliphatic acids) deriving mainly from sugars degradation. To avoid the inhibition of the biological
