Lignin characterization

The term "lignin characterization" refers to a group of activities within lignin research aiming at describing the characteristics of a lignin by determination of its most important properties. Most often, this term is used to describe the characterization of technical lignins by means of chemical or thermo-chemical analysis. Technical lignins are lignins isolated from various biomasses during various kinds of technical processes such as wood pulping. The most common technical lignins include lignosulphonates, kraft lignins, organosolv lignins, soda lignins and lignin residue after enzymatic treatment of biomass.
