“…For etherified xylans, aggregation at low degrees of substitution has also been observed, while an increased degree of modification resulted in reduced aggregation . For oxidized hemicelluloses, the aggregation has been reported to be correlated to concentration and inversely correlated to the degree of modification. , …”

“…As some native hemicelluloses are sparingly soluble in water, solvents such as aqueous alkaline solutions, DMSO, and cosolvent systems are used to dissolve or solubilize hemicelluloses. Additionally, chemical modification of hemicelluloses, for example, esterification, oxidation, and etherification, have been used to add functional groups, while modification of the backbone structure has also been employed to improve the hemicellulose–water interaction. , The degree of substitution was observed to play a key role in the solubilization of carboxymethylated GGM as the hydrodynamic volume increased as a function of degree of substitution . Carboxymethylation and dihydroxypropylation improved the water solubility of xylan, demonstrated by the reduced turbidity of the solutions as compared to unmodified xylans .…”

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.

“…Quenching of excess periodate with ethylene glycol is not only commonly used in cellulose modification but is also frequently used for other polysaccharides (Palasingh et al, 2022;Sarker et al, 2014;Wright et al, 2014). We were interested in whether also these oxidised polysaccharides partly trap the generated formaldehyde-without intending to study those cases exhaustively.…”

This article presents the isolation of arabinoxylan (AX) from Plantago ovata seed husk and its oxidation using periodate to create oxidized‐AX (OAX) with distinct functionalities. Utilizing the solution casting method, biocompatible blends of arabinoxylan/chitosan (AX/CS) are prepared at various weight ratios, and their properties are assessed. Fourier transform infrared spectroscopy (FT‐IR), x‐ray diffraction (XRD), and thermogravimetric analysis (TGA) are employed to gauge compatibility and thermal traits of AX and OAX with CS. Solubility tests reveal partial and limited solubility of AX and OAX in distilled water, respectively. OAX displays favorable compressibility and flow rate through Carr's index, Hausner's ratio, and angle of repose analyses. FT‐IR data confirm intermolecular hydrogen bonding between CS′s −NH2− group and OAX′s carbonyl group, with XRD showing low crystallinity. Diclofenac sodium (DC) is loaded as a model drug into AX/CS and OAX/CS blends for release studies in pH 6.8 phosphate buffer. Results exhibit OAX/CS blends with sustained drug release, surpassing AX/CS blends. Among ratios tested, the OAX/CS (1 : 2) blend emerges as a superior excipient, demonstrating enhanced in‐vitro release potential, highlighting oxidized blends′ promise in sustained drug delivery systems.
