摘要

Lignin is a sustainable and the most abundant aromatic biopolymer in the world, yet it is often regarded as a low-value byproduct of the pulp and paper industry. However, in recent years, interest in lignin biopolymer has surged across diverse fields due to its unique functional properties and potential applications across diverse industries. The antioxidant, antimicrobial and UV-blocking properties of lignin have been elucidated in recent years. In the food industry, its emulsion-stabilising property, potential applications for food stabilization and packaging have also gained recognition. This review provides an in-depth examination of recent developments in the chemistry and isolation of lignin, structural characterization, functional biological properties and applications across different fields. It highlights the enrichment of renewable biomass with lignin, the impact of isolation methods on the chemical structure, active sites and bioactivities, UV protection properties, potential applications in drug delivery and the synthesis of lignin-based bioplastics and films for food preservation.
