“…In contrast, these particles cannot be produced from the hydrolysate LCCs (e.g., H500) naturally due to their solubility in water and therefore this route is possible for AELs only, but not for earlier studied LCC samples. 26,27,30,37,40 Dynamic light scattering (DLS) results revealed a clear trend, where the particle size decreased with increasing P-factor, which is most probably attributed to the amount of carbohydrates in LCCs, frequency of lignin-carbohydrate linkages and differences in the molecular weights of the carbohydrate moieties that change the hydrophilic/hydrophobic balance of the different samples (Table 3). Native LCC preparations (BCEL and PLCC) also fit this tendency.…”

“…LCCs combine chemically linked aromatic and carbohydrate moieties exhibiting amphiphilic properties that create unique possibilities for their compatibility with different bioproducts. [23][24][25][26] For example, polysaccharides increase the emulsification performance of lignin and lignin nanoparticles (LNPs). 27,28 On the other hand, a positive effect of lignin moieties on the stabilization of galactoglucomannan (GGM)-based emulsions was recently claimed.…”

“…For wood hemicelluloses, this model is particularly prominent in describing the interfacial activity of hemicelluloses that contain lignin–carbohydrate complexes (LCC). The covalent bond between lignin and hemicelluloses indicates that the lignin moiety could act as a hydrophobic anchor to the oil phase, while the aqueous phase-facing hemicellulose moiety could impart steric stability. , Evidence of surfactant-like anchoring was provided by partitioning of adsorbed and unadsorbed hemicelluloses from model emulsions, followed by semiquantitative 2D nuclear magnetic resonance spectroscopy studies of the fractions . LCC species were found to be present in both fractions, with benzyl ether lignin-carbohydrate bonds (present in unpurified and nonpolar fractions of both PHWE GGM and GX) found exclusively bound to the oil–water interface.…”

A holistic utilization of all lignocellulosic wood biomass, instead of the current approach of using only the cellulose fraction, is crucial for the efficient, ecological, and economical use of the forest resources. Use of wood constituents in the food and feed sector is a potential way of promoting the global economy. However, industrially established food products utilizing such components are still scarce, with the exception of cellulose derivatives. Hemicelluloses that include xylans and mannans are major constituents of wood. The wood hemicelluloses are structurally similar to hemicelluloses from crops, which are included in our diet, for example, as a part of dietary fibers. Hence, structurally similar wood hemicelluloses have the potential for similar uses. We review the current status and future potential of wood hemicelluloses as food ingredients. We include an inventory of the extraction routes of wood hemicelluloses, their physicochemical properties, and some of their gastrointestinal characteristics, and we also consider the regulatory route that research findings need to follow to be approved for food solutions, as well as the current status of the wood hemicellulose applications on that route.

“…Their aromatic structure ensures good stability and mechanical properties. Those properties make lignins suitable for a wide sphere of applications, such as adhesives, flocculants, surfactants, dispersant agents, compatibilizers, stabilizers, flame retardants, binders, additives to composites, in energy storage, and 3D printing applications [ 8 , 20 , 21 , 22 , 23 , 24 , 25 ]. Their high amount of carbon, mechanical stability, and good rheological and viscoelastic properties also make them suitable candidates as additives and fillers for rubber compounds [ 1 , 26 , 27 , 28 , 29 , 30 , 31 , 32 ].…”

The work deals with the application of biopolymer fillers in rubber formulations. Calcium lignosulfonate was incorporated into styrene–butadiene rubber and acrylonitrile–butadiene rubber in a constant amount of 30 phr. Glycerol in a concentration scale ranging from 5 to 20 phr was used as a plasticizer for rubber formulations. For the cross-linking of the compounds, a sulfur-based curing system was used. The study was focused on the investigation of glycerol in the curing process; the viscosity of rubber compounds; and the cross-link density, morphology, physical–mechanical, and dynamic mechanical properties of vulcanizates. The study revealed that the application of glycerol as a plasticizer resulted in a reduction in the rubber compounds’ viscosity and contributed to the better dispersion and distribution of the filler within the rubber matrices. The mutual adhesion and compatibility between the filler and the rubber matrices were improved, which resulted in the significant enhancement of tensile characteristics. The main output of the work is the knowledge that the improvement of the physical–mechanical properties of biopolymer-filled vulcanizates can be easily obtained via the simple addition of a very cheap and environmentally friendly plasticizer into rubber compounds during their processing without additional treatments or procedures. The enhancement of the physical–mechanical properties of rubber compounds filled with biopolymers might contribute to the broadening of their potential applications. Moreover, the price of the final rubber articles could be reduced, and more pronounced ecological aspects could also be emphasized.
