Characterization of Lignin Extracted from Spent Black Tea Leaves and the Effects of Process Parameters on Structure

Lignin is a part of the plant cell wall bridging the gap between cellulose and hemicellulose and is synthesized from phenolic derivatives (monolignols; p-coumaryl, coniferyl and sinapyl alcohols). The existence of phenolic and aliphatic hydroxyl groups provides ample possibilities for chemical modification. Isolation of lignin from lignocellulosic biomass is achieved via various processes such as kraft, organosolv or soda pulping. Among these, soda pulping is particularly advantageous for producing sulfur-free lignin suitable for biomedical use. The initial botanical source can be any plant, including agricultural, forestry or food wastes. However, the properties of lignin isolated depend on the process used as well as the type of the initial source and should be investigated rigorously prior to implementation.
