“…Consequently, the highest total color difference (ΔE) was observed after blending the G/PVA mixture with BCCE and ZnONPs (ΔE = 7.9). Javidi et al [ 43 ] also reported a decrease in the lightness of gelatin nanocomposites owing to the presence of ZnONPs and Mentha piperita extract. Similar observations of color changes were described by Shahvalizadeh et al [ 35 ].…”

This study aimed to develop and characterize gelatin/polyvinyl alcohol (G/PVA) films loaded with black cumin cake extract (BCCE) and zinc oxide nanoparticles (ZnONPs). The BCCE was also applied for the green synthesis of ZnONPs with an average size of less than 100 nm. The active films were produced by a solvent-casting technique, and their physicochemical and antibacterial properties were investigated. Supplementation of G/PVA film in ZnONPs decreased the tensile strength (TS) from 2.97 MPa to 1.69 MPa. The addition of BCCE and ZnONPs increased the elongation at the break (EAB) of the enriched film by about 3%. The G/PVA/BCCE/ZnONPs film revealed the lowest water vapor permeability (WVP = 1.14 × 10−9 g·mm·Pa−1·h−1·mm−2) and the highest opacity (3.41 mm−1). The QUick, Easy, New, CHEap and Reproducible (QUENCHER) methodologies using 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azino-bis(3-ethylbenzothiazoline-6- sulfonic acid) (ABTS) and cupric ion reducing antioxidant capacity (CUPRAC) were applied to measure antioxidant capacity (AC) of the prepared films. The incorporation of BCCE and ZnONPs into G/PVA films enhanced the AC by 8–144%. The films containing ZnONPs and a mixture of BCCE and ZnONPs inhibited the growth of three Gram-positive bacterial strains. These nanocomposite films with desired functional properties can be recommended to inhibit microbial spoilage and oxidative rancidity of packaged food.

The objective of this study is to investigate the synergistic effects of nano titanium dioxide (TiO 2 -N) and Mentha piperita essential oil (MEO) on cassava starch film characteristics. Cassava starch films with TiO 2 -N (1%, 3%, and 5% of dried starch) and MEO (1%, 2%, and 3% of dried starch) are prepared by a casting method. Physicochemical, mechanical, barrier, and optical properties of the films are evaluated. The moisture content, solubility, water absorption capacity, water vapor permeability, and transparency of films significantly decrease with the incorporation of TiO 2 -N and MEO. The color of bionanocomposite films is darker, yellower, and redder than that of the control film. The highest tensile strength (23.39 MPa), highest Young's modulus (39.51 MPa), and lowest elongation (6.63%) are observed in the film containing 5% TiO 2 -N and 1% MEO. The incorporation of TiO 2 -N and MEO reduces the percentage of UV transmitted from films. In summary, the results show that the combination of TiO 2 -N and MEO improves the starch film characteristics, and these bionanocomposite films could be used for food packaging or coating.

Physico-Mechanical Optimization and Antimicrobial Properties of the Bionanocomposite Films Containing Gallic Acid and Zinc Oxide Nanoparticles

The mechanical and physical properties of the bionanocomposite films based on κ-carrageenan (KC)–gelatin (Ge) containing zinc oxide nanoparticles (ZnONPs) and gallic acid (GA) were optimized using the response surface method, and the optimum amounts of 11.19 wt% GA and 1.20 wt% ZnONPs were obtained. The results of XRD, SEM, and FT-IR tests showed the uniform distribution of the ZnONPs and GA in the film microstructure, and suitable interactions between biopolymers and these additives, which led to increasing the structural cohesion of the biopolymer matrix and improving the physical and mechanical properties of the KC–Ge-based bionanocomposite. In the films containing gallic acid and ZnONPs, an antimicrobial effect was not observed against E. coli; however, the GA-loaded and optimum films show an antimicrobial effect against S. aureus. The optimum film showed a higher inhibition effect against S. aureus compared to the ampicillin- and gentamicin-loaded discs.
