“…This functional group can modify the physiological process of the microorganism, leading to damaging the cell membrane and eventually causing the loss of functionalities of the microorganism [ 78 , 79 ]. It was suggested that the phenolics in lignin can disrupt the cell wall, resulting in altered physiological processes and, eventually, dysfunction of parts of the microorganism and growth inhibition [ 20 ].…”

“…In this present work, softwood kraft lignin was processed into nanoparticles to achieve the advantages of nano-size particles in terms of reactivity. Moreover, different classifications of lignin will produce different results when blended with a polymer, because the reaction is affected by the complexity of the lignin structure, which is dependent on the source and isolation process [ 19 , 20 ].…”

The natural abundance, polymer stability, biodegradability, and natural antimicrobial properties of lignin open a wide range of potential applications aiming for sustainability. In this work, the effects of 1% (w/w) softwood kraft lignin nanoparticles (SLNPs) on the physicochemical properties of polybutylene succinate (PBS) composite films were investigated. Incorporation of SLNPs into neat PBS enhanced Tg and Td from −39.1 °C to −35.7 °C and 354.1 °C to 364.7 °C, respectively, determined through TGA, whereas no significant change was observed in Tm and crystallinity, analyzed through DSC. The tensile strength of neat PBS significantly increased, to 35.6 MPa, when SLNPs were added to it. Oxygen and water vapor permeabilities of PBS with SLNPs decreased to 1.59 × 10−3 cm3 m h−1 m−2 atm−1 and 1.41 × 10−3 g m h−1 m−2 atm−1 compared with neat PBS with 2.28 × 10−3 cm3 m h−1 m−2 atm−1 and 1.54 × 10−3 g m h−1 m−2 atm−1, respectively, equating to enhanced barrier properties. The good interactions among SLNPs, thymol, and PBS matrix, and the high homogeneity of the resultant PBS composite films, were determined through FTIR and FE-SEM analyses. This work revealed that, among the PBS composite films tested, PBS + 1% SLNPs + 10% thymol showed the strongest microbial growth inhibition against Colletotrichum gloeosporioides and Lasiodiplodia theobromae, both in vitro, through a diffusion method assay, and in actual testing on active packaging of mango fruit (cultivar “Nam Dok Mai Si Thong”). SLNPs could be an attractive replacement for synthetic substances for enhancing polymer properties without compromising the biodegradability of the resultant material, and for providing antimicrobial functions for active packaging applications.

How to effectively protect lignin so that it can play a role in the field of food preservation in a long-term and stable way is a problem we need to solve. Herein, first, we used the “armor” prepared by poly(vinyl alcohol) and acrylate epoxidized soybean oil to comprehensively protect lignin through emulsion polymerization and obtained AS-lignin nanoparticles (NPs). Subsequently, a multifunctional AS-lignin NPs/ cellulose acetate (CA) membrane was obtained by implanting AS-lignin NPs into a CA fiber network via the electrostatic spinning technique. The incorporation of AS-lignin NPs in the CA matrix resulted in improved stress transfer from the CA matrix to the filler, leading to a significant enhancement of its mechanical properties. These membranes possess various properties, such as UV and visible light barriers, oxidation resistance, thermal stability, excellent oxygen barrier, water vapor barrier, and antimicrobial properties. Notably, the shelf life of fresh apples was extended by at least 3 days under ambient conditions when they were covered by these membranes. These membranes can be safely degraded in the natural environment. This means that our work introduces a novel concept of using lignin as a template to develop food preservation materials with unique properties. This approach holds great promise for creating a new generation of food preservation membranes.

“…Lignin is one of the richest multifunctional aromatic biomass resources [ 7 ]; it contains many aliphatic and phenolic OH groups and stilbene and arylenol ether groups offering vast opportunities for functionalization [ 8 , 9 , 10 ]. However, the global pulp and paper industry and bioethanol processing enterprises process 98% of lignin as low-value fuel or waste [ 10 ]; in other words, lignin is not used to its maximum potential.…”

New Azo Derivatives of Ethanol Lignin: Synthesis, Structure, and Photosensitive Properties

Water-soluble azo derivatives of lignin were synthesized by the azo coupling reaction using organosolv ethanol lignin and diazonium salts based on sulfanilic acid and p-nitroaniline. The structure of azo derivatives of lignin were studied by nuclear magnetic resonance, Fourier-transform infrared spectroscopy, and gel permeation chromatography. It was found that the azobenzene bonds formed in the azo coupling reaction of macromolecules impart the photosensitive properties to the synthesized polymers via cis–trans photoisomerization of the diazobenzene group. It was shown experimentally that the synthesized polymers exhibited good solubility both in the aqueous media in a wide (2–12) pH range and in DMSO and THF organic solvents, which opens up new prospects for their application.
