Otimização do método de extração de lignina de mandioca utilizando sistema acelerado por solvente (ASE)

Abstract

Cassava is a tuberous root which varied use makes it a beneficial product for many countries. Its adaptation to tropical and subtropical climate as well as poor soils makes this root serve as a food base for African countries, also contributing to the economies of these countries. Lignin is a macromolecule formed by the polymerization of three alcohols, amorphous and that has a function is to increase the resistance of the cell wall and provide protection against pathogens. This molecule is well studied due to the complexity of the bonds and the diversity of compounds that can be originated in its extraction. This work aimed to improve lignin extraction using the solvent-accelerated system (ASE) and compare it with the Soxhlet extraction method applied the 1H-13C HSQC technique to study the quality of the extracts obtained by the extraction methods, at different times, from the characteristic components of lignin such as syringyl, guaiacil.
