“…Further observation interpreted a trend that the cellulose II structure turned to cellulose I type, lowering CrI as ball milling time prolonged. The ball milling potentially disrupted the binding lignocellulose matrix, exposing inter amorphous area (including hydrophilic hemicellulose and hydrophobic lignin) due to the deconstruction of intermolecular hydrogen bonds (Lazic et al., 2021). As a result, more crystalline zone turned to amorphous state.…”

This work is focused on the modification of insoluble dietary fiber from pomelo (Citrus grandis) peel (PP‐IDF) by ball milling. Ball milling intensified water and oil holding capacity and water swelling capacity by 43.7%, 65.1%, and 107.5%, respectively. Besides, 97.1% of taurocholic acid, 45.3% of glucose, and 9.3 μg/mg of NO2− were bound by milled insoluble dietary fibers (IDFs). The oil‐in‐water Pickering emulsions were successfully emulsified by ball‐milled PP‐IDFs. The ball‐milled PP‐IDF for 2.0 hr (PP‐IDF‐BM2h) exhibited higher stability after storage owing to its relative strong electrostatic and steric repulsions intensified by milling process. A simulated three‐stage gastrointestinal tract (GIT) model was employed to explore the physical stability of emulsion in the digestive system. Ball milling contributed promotion on stability emulsion but ion strength in simulated liquids predominated in affecting ζ potential. Overall, ball milling extended green protocols for modification of properties for dietary fiber, providing a promising application in food industry. Practical applications For safety consideration, materials used for food processing should be in low toxicity with less employment of chemicals. Hence, it is essential to develop a green and renewable strategy to modify properties of dietary fiber (DF) in food applications. Ball milling is a simple and low cost strategy that can effectively improve or modify physicochemical properties including crystallinity, surface potential, water and oil holding capacities, and hydrophilic and hydrophobic properties. Importantly, ball milling can treat dietary fiber in batch processing with no waste and chemicals, which is suitable for industrial applications.

“…Raw jute (J), like other cellulosic fibers, exhibited a negative zeta potential in the entire measured pH range, which is a consequence of the presence of hydroxyl and carboxyl groups on its surface that are susceptible to dissociation upon contact with an electrolyte solution resulting in a negative charge [41]. Due to the removal of fabric surface impurities during the oxidation, such groups become more accessible leading to an increase in the fabrics' active sites which is evident from more negative ζ plateau value.…”

“…Furthermore, alkali treated fibers have a greater capacity for sorption of moisture, a characteristic attributed to the increased availability of hydroxyl groups on cellulose fibers following hemicellulose removal. [6] Oxidative treatment, in addition to improving the whiteness of the fibers by removing their natural color, can also have two chemical effects [8]: oxidation of cellulose, which results in the cleavage of carbon-carbon bonds and the production of dialdehydes [9], and oxidative depolymerization of lignin through cleavage of C-C links [8][9][10]. Due to the abundance of the hydroxyl groups, jute fiber provides sufficient connection sites for oxide and nitride-based semiconductor photocatalysts through hydrogen bonding, and as such can be very attractive for the application in photocatalysis as a photocatalyst's carrier, bypassing the common problem in heterogeneous photocatalysis: photocatalysts retrieval from the reaction mixture and its reuse in the consecutive processes.…”

Non-woven jute (NWJ) produced from the carpet industry waste was oxidized by H2O2 or alkali treated by NaOH and compared with water-washed samples. Changes in the structure of the NWJ, tracked by XRD, showing that both chemical treatments disrupt hydrogen bond networks between cellulose Iβ chains of the NWЈ fibers. Thereafter, nano carbon nitride (nCN) was impregnated, using layer-by-layer technique, onto water washed jute sample (nCN-Jw), NaOH treated sample (nCN-Ja) and H2O2 treated sample (nCN-Jo). Analysis of the FTIR spectra of the impregnated samples, revealed that nCN anchors to the water washed NWЈ surface through hemicellulose and secondary hydroxyl groups of the cellulose. In the case of chemically treated samples nCN is preferentially bonded to the hydroxymethyl groups of cellulose. The stability and reusability of nCN-J samples were assessed by tracking the photocatalytic degradation of Acid Orange 7 (AO7) dye under simulated solar light irradiation. Results from up to ten consecutive photocatalytic cycles demonstrated varying degrees of effectiveness across different samples. nCN-Jo and nCN-Ja samples exhibited declining effectiveness over cycles, attributed to bond instability between CN and jute. In contrast, the nCN-Jw sample consistently maintained high degradation rates over ten cycles, with a dye removal percentage constantly above 90%.
