“…[63][64][65] The peak in the 1750-1690 cm À1 region was attributed to the C O and the C O functional groups present within the ester groups that were formed by the crosslinking reaction between the methyl ester (methoxy) groups of pectin and the aromatic hydroxyl groups (OH) of lignin, as well as to the unreacted carboxylic groups present within pectin. 55 Moreover, the C O stretching peaks arising from the uronic esters in pectin and acetyl functional groups present in lignin were also detected in this vibration region. 66 The 1635-1623 cm À1 vibration region was attributed to the conjugated C H stretching frequency due to the phenolic rings of lignin present within hemp fibers.…”

“…[76][77][78][79] Since the pectin used in our process had a DE of 70%-75%, the corresponding methyl ester groups of the pectin likely contributed most to the crosslinking reaction which has been previously reported. 53,55,[80][81][82] Transesterification is an important class of organic reactions where an ester is transformed into another ester through the interchange of the alkoxy moiety. It is an equilibrium reaction, but it can be accelerated considerably by using a catalyst (strong acid or base).…”

“…54 Recently, pectin was used as a non-toxic crosslinker for making high tensile strength polyvinyl alcohol (PVA) membranes in aqueous media. 55 Apart from this, pectin has been applied in making a wide array of specialty products such as edible bio-based films, bioadhesives, green plasticizers, natural surface modifiers for application in drug delivery and designing medical diagnostic devices, and other materials aiding in making biomedical implants and prosthetics because pectin can affect various enzymatic and non-enzymatic processes in our body.

In this paper, an environmentally friendly fabrication process was reported to valorize hemp fibers into biocomposites through a pectin-based crosslinking reaction. In this water-based chemical approach, the hemp fibers were crosslinked via a transesterification process between pectin and lignin present in hemp fibers to produce hemp fiber composites in a one-step process. Our green process was advantageous over conventional processes that rely on the use of petroleum-based organic solvents and high reaction temperatures because water was used as the reaction solvent with a mild reaction temperature (70 C). Additionally, to further optimize this biocomposite fabrication process, one-factor analysis of variance study was carried out for investigating the main and interaction effects of the mass ratios of pectin to hemp fiber (1:5, 2:5, 3:5, 4:5, and 5:5) on the compressive strength and bulk density of the hemp fiber composite materials. In addition, the fabrication process was explored at different pH values to probe its versatility. The compressive strength of the assynthesized hemp fiber composite materials was observed to be dependent on the pH of the reaction conditions, indirectly confirming the formation of ester bonds between pectin and the lignin of hemp fibers via transesterification.

“…On the other hand, the elongation at break had no difference among the film composition. The main drawback of pectin-based films in applications relies on their limited mechanical properties, as they become, under specific drying conditions more rigid, brittle and have low elongation at break (EB < 25 %) [30][31][32][33]. Thus, the increment in such properties is essential.…”

Edible films were produced combining pectin (P) matrix with chitosan nanoparticle (CSNP), polysorbate 80 (T80), and garlic essential oil (GEO) as an antimicrobial agent. The CSNP were analyzed for their size and stability, and the films, throughout their contact angle, scanning electron microscopy (SEM), mechanical and thermal properties, WVP and antimicrobial activity. Four filming-forming suspension were investigated: PGEO (control); PGEO@T80; PGEO@CSNP; PGEO@T80@CSNP. The average particle size was 317nm with zeta potential reaching +21.4 mV, which indicated colloidal stability. The wettability of the films exhibited values of 65°, 43°, 78°, 64° respectively. In antimicrobial tests, the films containing GEO showed inhibition only by contact for S.aureus. For E. coli, the inhibition occurred only in films containing CSNP and by direct contact in the culture. The results indicate a promising alternative for designing stable antimicrobial nanoparticles for application in novel food active packaging.

In this study, we developed a pH‐responsive hydrogel membrane composed of pectin, dimethylaminoethyl methacrylate (DMAEMA), and acrylic acid (AA) through a free radical‐triggered graft copolymerization method. Freshly formed silver nanoparticles (AgNPs) produced from the reduction reaction were embedded in the produced hydrogel. Pectin‐grafted dimethylaminoethyl methacrylate and acrylic acid copolymer [poly (DMAEMA‐co‐AA)‐g‐pectin] and its bionanocomposite with AgNPs were confirmed by Fourier‐transform infrared spectroscopy (FT‐IR), scanning electron microscopy (SEM), and thermogravimetric analysis (TGA). The swelling behavior of poly (DMAEMA‐co‐AA)‐g‐pectin in solutions with diverse pH values was assessed. For use as a controlled drug delivery agent, the hydrogel was loaded with 5‐fluorouracil (5‐FU). The incorporation of AgNPs had a great impact on the entrapment efficiency of 5‐FU. At pH 7.4, nearly 48% of the 5‐FU was released in vitro from the polymeric nanocomposite within 24 h. Moreover, poly (DMAEMA‐co‐AA)‐g‐pectin and poly (DMAEMA‐co‐AA)‐g‐pectin/AgNPs presented high cytocompatibility toward normal skin fibroblast cells (BJ1), and the drug delivery system strongly inhibited human Caucasian breast adenocarcinoma cells (MCF‐7). These results demonstrated that these poly (DMAEMA‐co‐AA)‐g‐pectin/AgNPs are an excellent candidate for use in anticancer drug delivery systems.Highlights Free radical polymerization of nanocomposites incorporated with nanoparticles. Nanoparticles improve the bionanocomposites' drug loading. The developed bionanocomposites exhibit control drug release. The novel bionanocomposites acts as an excellent anticancer drug carrier.
