“…SEM images revealed that the surface microstructure of control is smooth and uniform (Fig. 3b, control) which indicates good biocompatibility between the film components and the extensive crosslinking among PVA and citric acid (Zarandona et al ., 2021). Film L3 with higher lignin level (0.3%), showed a rough surface with some wave or transverse patterns (Fig.…”

The present study involved valorization of rice straw via production of biopolymeric films loaded with lignin and evaluation of their physical, mechanical, structural, antioxidant, antibacterial and biodegradable properties. Lignin (0.1%, 0.2% and 0.3%) loaded films were prepared by solvent casting method involving successful crosslinking between PVA, citric acid and lignin which was confirmed by ester bond formation at 1710 cm −1 in Fourier transform infrared spectrum. Scanning electron micrographs showed smooth surface in control and wavy surface in lignin film with no cracks. Lignin films possessed thickness, tensile strength and elongation at break in the range 0.127-0.142 mm, 22-31.38 MPa and 11.83-17.63%, respectively. Lightness value of films decreased while yellowness index increased as the level of lignin increased in films. Lignin loaded films showed potential antioxidant activity (51.4-74.6%) and antibacterial efficacy against Pseudomonas (diameter of inhibition zone 4.1 cm), thus suggesting their role in prevention of bacterial food contamination and organoleptic changes in food. The biodegradability tests showed that weight loss experienced by films after burial in soil was above 78.7% which offers a great advantage of these biopolymeric films over non-biodegradable synthetic plastics, hence, these may be explored further as bioplastics to replace plastic wraps in food packaging.

“…As for CG film, the broad absorption bands around 3500-3000 cm −1 were assigned to the O-H and N-H stretching vibration (-OH, -NH 2 , also between -OH and -NH 2 ), the absorption peaks at 2882 cm −1 were assigned to the C-H symmetric stretching vibrations of -CH 2 groups [38,39], at 1632 cm −1 , 1551 cm −1 and 1332 cm −1 can be attributed to the C=O stretching of amide I, N-H bending of amide II and C-N stretching of amide III, respectively [40]. Moreover, the absorption peak at 1408 cm −1 can be attributed to the bending stretching of -CH 2 [41], at 1150 cm −1 were assigned to the symmetric stretching of C-O-C bond, and at 1028 cm −1 were assigned to the C-O stretching vibrations [42][43][44]. In addition, the C=O stretching vibrations of GA can also be observed at 2943 cm −1 [45].…”

The synergistic effect of chitosan (CS), glycyrrhizic acid (GA) and ZnO/palygorskite (ZnO/PAL) as potential wound dressing was evaluated in the form of films by the solution casting method. The nanocomposite films were well-characterized with ATR-FTIR, XRD and SEM to explore the interactions between CS, GA and ZnO/PAL. Physical, mechanical and antibacterial properties of the nanocomposite films were systematically investigated for their reliability in end-up utilization. Importantly, it was found that the presence of PAL in the films provided enhanced mechanical properties, whereas CS, GA and ZnO supplied a broad-spectrum antibacterial activity, especially for drug-resistant bacteria such as ESBL—E. coli and MRSA. Overall, this research demonstrated that the prepared films can be a promising candidate for wound-care materials.

“…To overcome these disadvantages, researchers have explored multiple ways of modifying the CH, out of which the blending of CH with other bio-based materials is considered promising. Combining such materials with CH has enhanced its thermal and mechanical stability and improved the antioxidant and antimicrobial properties of CH-based edible films and coatings [ 20 , 21 ]. It was reported that the properties of pure CH have been improved by combining it with other polymers and plant extracts such as starch, guar gum, alginate, carboxy methyl cellulose, gelatin, pineapple peel extract, lemon peel extract, basil essential oil [ 22 , 23 , 24 , 25 , 26 , 27 , 28 ].…”

Food bioactive packaging has received increasing attention from consumers and the food industry for its potential to reduce food waste and environmental issues. Several materials can be used to produce edible films/coats; however, bio-based, cost-effective, and sustainable coatings have gained a high reputation these days. For instance, Aloe vera gel (AV) is a promising bio-based material for edible coatings and films; therefore, the present study aimed to investigate the film-forming abilities of AV and Chitosan (CH) combination as a potential active food packaging material. The physicochemical and mechanical characteristics of formed films of various combinations were prepared at different concentrations, i.e., CH (0.5% w/v), AV (100%), CH:AV (75:25), and CH:AV (60:40). The results showed significant differences among all the prepared edible films wherein these differences were mainly on account of incorporating AV gel. The rheological and antioxidant properties of the formulations improved with the inclusion of AV gel. The films composed of CH:AV (60:40) positively affected the water solubility, thermal properties, and water vapour permeability of the edible films. The X-ray Diffraction (XRD) and Scanning electron microscopy (SEM) results showed that the films composed of CH:AV, (60:40) were amorphous and had smooth morphology. Further, the edible film solutions were applied to fresh figs (Ficus carica) to investigate their role in preserving fruits during storage. A significant reduction in microbial growth was found in coated fruits after 28 days of cold storage. The films composed of CH and AV showed overall improved results compared to the CH (0.5%, w/v). Therefore, the used formulations (CH:AV, 60:40) can form a sustainable film that has the potential to be utilized for fresh product preservation to maintain its quality and shelf life.
