“…This can be related to the interaction between TiO 2 positive charges and the negative charge of carboxylic groups of CMC matrix. Similarly, previous studies reported the increase in TSB and decrease in EB by adding TONP into chitosan, 57 potato starch18 and soluble soybean polysaccharide matrix 58. Dependent on the plant extract components, the effects of plant extracts are variable.…”

Objective: The microbial, physico-chemical and optical corruptions threaten a variety of foods and drugs and consequently the human biological safety and its accessible resources. The humanbeing’s tendency towards bio-based materials and natural plant-extracts led to an increase in the usage of antimicrobial biocomposites based on medicinal herbs. Miswak ( Salvadora persica L.) extract (SPE) has been proved effective for its antimicrobial and other biological activities. Therefore, in this study, titanium dioxide (TiO 2 ) nanoparticles (TONP) and SPE were applied to fabricate antimicrobial carboxymethyl cellulose (Na-CMC) based bio-nanocomposites which would simultaneously promote some thermo-physical and barrier properties. Methods: CMC-neat film (C1), CMC/TONP-2% (C2) and CMC/TONP-2% with 150, 300 and 450 mg/mL SPE (SPE150, SPE30 and SPE450, respectively) were fabricated. The physical and mechanical properties; elemental mapping analysis (MAP), X-ray diffraction (XRD), scanning electron microscopy (SEM), thermal gravimetric analysis (TGA-DTG); fourier transform infrared (FTIR), energy-dispersive X-ray (EDX) and UV-vis spectroscopies were done to further validate the results. Results: Addition of TONP (2%) improved the blocking of UV light at 280 nm while SPE-containing nanocomposites completely blocked it. FTIR, XRD and SEM confirmed the formation of homogeneous films and high miscibility of applied materials. TONP led to an increase in Young’s modulus (YM) and stress at break (SB) while SPE decreased them and enhanced the elongation to break (EB) (flexibility) of the active nanocomposites. Compared to CMC-film, the thermo-gravimetric analysis (TGA-DTG) showed a higher thermal stability for CMC/TONP and CMC/TONP/SPE nanocomposites. The EDX spectroscopy and elemental mapping analysis (MAP) proved the existence and well-distributedness of Na, K, Cl, S, Ti, F and N elements in SPE-activated nanocomposites. The pure SPE and SPE-activated nanocomposites showed a favorable antimicrobial activity against both gram-positive ( Staphylococcus aureus ) and negative ( Escherichia coli ) bacteria. Conclusion: The CMC-TiO 2 -SPE nanocomposites were homogeneously produced. Combination of TiO 2 nanoparticles and dose-dependent SPE led to an improvement of thermal stability, and high potential in antimicrobial and UV-barrier properties. These results can generally highlight the role of the fabricated antimicrobial bio-nanocomposites as a based for different applications especially in food/drug packaging or coating.

“…WS of the films is a critical property in food packaging and commonly considered as an indicator of water tolerance (Abdollahi et al., 2013; Salarbashi et al., 2018). The films with a low level of WS can effectively protect foods against physical and microbial spoilage.…”

The objective of the present work was first to develop a smart packaging system based on Lallemantia iberica seed gum (LISG)/curcumin and, subsequently, investigate its physicochemical characteristics and biological activity. Finally, the response of LISG/curcumin films against pH change and the spoilage of shrimp were tested. The barrier properties and mechanical performance of the films improved as the curcumin concentration increased. FT‐IR analysis revealed the formation of physical interaction between LISG and curcumin. LISG/curcumin films showed a continuous and steady release of curcumin. The incorporation of curcumin into LISG matrix imparts antioxidant and antibacterial/mold activity to the films. A strong positive correlation was observed between total volatile base nitrogen (TVBN) content of shrimp and a* (redness) during storage time (Pearson correlation = 0.975). Eventually, LISG/curcumin film could be a promising smart packaging system capable of detecting food spoilage.

“…In contrast, the EB of the CS coating is enhanced notably by nano‐TiO 2 and in situ modification nano‐CaCO 3 , and the former effect is higher. It is demonstrated that the structure compactness of the CS coating can be increased effectively due to the intermolecular action of CS molecule and active groups on the nano‐TiO 2 surface (Salarbashi et al ., 2018).…”

“…Nano-TiO 2 is one of the most popular inorganic materials, which has the characters of biocompatibility, non-toxicity, antibacterial activity, and anti-ultraviolet capability (Luo et al, 2015;Salarbashi et al, 2018)). Studies have reported that the physicochemical properties of polymer composites can be significantly improved by TiO 2 nanoparticles (Adams et al, 2006;Subhapriya & Gomathipriya, 2018).…”

Calcium hydroxide reacts with carbon dioxide to produce nano‐CaCO3 and water. At the same time, the modifier sodium stearate is adsorbed on the surface of nano‐CaCO3 to form in‐situ modified nano‐CaCO3. Then, the nanoparticles are added to the CS solution. The sodium stearate on the surface of nano‐CaCO3 and the polyethylene glycol 400 on the surface of nano‐TiO2 form hydrogen bonds with the amino and hydroxyl groups of chitosan. The nanoparticles and NH3+ charges in CS coating are absorbed to the surface of cell membrane by electrostatic interaction, and result in the change of integrality and permeability of cell membrane. So, the bacteria are killed.
