“…The best properties were observed in the film F1-90, followed by F1-Glu-90 and F2-90 (p < 0.05). Our results disagreed with those reported by of Hosseini, Razavi, & Mousavi (2009) and Affes et al (2020a) who suggested that the increase in the EAB of the films can be ascribed to the increased WC values. According to the literature, the improvement of mechanical properties of heated films is highly dependent on the distribution and density of both intermolecular and intramolecular interactions in the network created in chitosan films, thus leading to the formation of more compact structure induced by crosslinking through MR (Park et al, 1999).…”

“…For this purpose, biopolymers, including proteins and polysaccharides are increasingly being used to prepare composite films and coating (Etxabide, Urdanpilleta, Gómez-Arriaran, de la Caba, & Guerrero, 2017; Kchaou, Benbettaieb, Jridi, Nasri, & Debeaufort, 2019). Among the most studied biopolymers, chitosan, a natural polysaccharide derived from chitin and composed of D-glucosamine and N-acetylglucosamine units, deserves special attention due its biological properties, such as biocompatibility, non-toxicity, biodegradability and good film-forming ability (Affes et al, 2020a;Hajji, Younes, Affes, Boufi, & Nasri, 2018). Such characteristics of chitosan depended on its acetylation degree, distribution of acetyl groups, viscosity and especially its molecular weight (Mw).…”

This work focused on studying the physicochemical and antioxidant properties changes of varying molecular weight (Mw) chitosan-depolymerization products (CDP)-based films occurring after crosslinking by heat-treatment and Maillard reaction (MR). Based on color properties and browning index, an enhancement of films properties was observed after treatment at 90 °C with a reduction in their water content, solubility and contact angle. Brown MR products were developed in heated films containing glucose thus improving their barrier properties. This effect was more pronounced in lower Mw-CDP based films. In addition, according to TGA, EAB and TS analyses an improvement in heat-treated films thermal stability and mechanical properties was detected and further confirmed through FTIR, X-ray and SEM analyses. The evaluation of the antioxidant potential through four different assays allowed to conclude that glucose addition, thermal treatment and the use of low Mw-CDP highly enhanced the MR-modified films antioxidant capacity. Consequently, MR crosslinked chitosan-based films could be potentially used as an alternative for bioactive and functional packaging effective in food oxidation inhibition, especially using low Mw chitosan derivatives.

Green Synthesis of Metal and Metal Oxide Nanoparticles Using Different Plants’ Parts for Antimicrobial Activity and Anticancer Activity: A Review Article

Nanotechnology emerged as a scientific innovation in the 21st century. Metallic nanoparticles (metal or metal oxide nanoparticles) have attained remarkable popularity due to their interesting biological, physical, chemical, magnetic, and optical properties. Metal-based nanoparticles can be prepared by utilizing different biological, physical, and chemical methods. The biological method is preferred as it provides a green, simple, facile, ecofriendly, rapid, and cost-effective route for the green synthesis of nanoparticles. Plants have complex phytochemical constituents such as carbohydrates, amino acids, phenolics, flavonoids, terpenoids, and proteins, which can behave as reducing and stabilizing agents. However, the mechanism of green synthesis by using plants is still highly debatable. In this report, we summarized basic principles or mechanisms of green synthesis especially for metal or metal oxide (i.e., ZnO, Au, Ag, and TiO2, Fe, Fe2O3, Cu, CuO, Co) nanoparticles. Finally, we explored the medical applications of plant-based nanoparticles in terms of antibacterial, antifungal, and anticancer activity.

“…The second decomposition was achieved in the range of 220-330 • C for the unmodified film and 220 to 450 • C for the modified film. According to previous studies, degradation around 220 • C suggests that dehydration and decomposition of macroalgae and glycerol occurred in the biopolymer films [35,36]. However, approximately 49% weight loss was achieved at this stage around 280 • C for the unmodified film.…”

Improved Hydrophobicity of Macroalgae Biopolymer Film Incorporated with Kenaf Derived CNF Using Silane Coupling Agent

et al. 2021

Hydrophilic behaviour of carrageenan macroalgae biopolymer, due to hydroxyl groups, has limited its applications, especially for packaging. In this study, macroalgae were reinforced with cellulose nanofibrils (CNFs) isolated from kenaf bast fibres. The macroalgae CNF film was after that treated with silane for hydrophobicity enhancement. The wettability and functional properties of unmodified macroalgae CNF films were compared with silane-modified macroalgae CNF films. Characterisation of the unmodified and modified biopolymers films was investigated. The atomic force microscope (AFM), SEM morphology, tensile properties, water contact angle, and thermal behaviour of the biofilms showed that the incorporation of Kenaf bast CNF remarkably increased the strength, moisture resistance, and thermal stability of the macroalgae biopolymer films. Moreover, the films’ modification using a silane coupling agent further enhanced the strength and thermal stability of the films apart from improved water-resistance of the biopolymer films compared to unmodified films. The morphology and AFM showed good interfacial interaction of the components of the biopolymer films. The modified biopolymer films exhibited significantly improved hydrophobic properties compared to the unmodified films due to the enhanced dispersion resulting from the silane treatment. The improved biopolymer films can potentially be utilised as packaging materials.
