“…The emulsifying property of GE expands its use in the food industry, and it is used in a variety of food stuff [ 4 ]. The opulent film-forming ability [ 5 ] of GE has been considerably used to preserve the food from the external environment, such as light, air, and microorganisms. Hence, it is a magnificent food packaging material and helps lengthen the shelf life of food materials.…”

The food packaging industry explores economically viable, environmentally benign, and non-toxic packaging materials. Biopolymers, including chitosan (CH) and gelatin (GE), are considered a leading replacement for plastic packaging materials, with preferred packaging functionality and biodegradability. CH, GE, and different proportions of silver nanoparticles (AgNPs) are used to prepare novel packaging materials using a simple solution casting method. The functional and morphological characterization of the prepared films was carried out by using Fourier transform infrared spectroscopy (FTIR), UV–Visible spectroscopy, and scanning electron microscopy (SEM). The mechanical strength, solubility, water vapor transmission rate, swelling behavior, moisture retention capability, and biodegradability of composite films were evaluated. The addition of AgNPs to the polymer blend matrix improves the physicochemical and biological functioning of the matrix. Due to the cross-linking motion of AgNPs, it is found that the swelling degree, moisture retention capability, and water vapor transmission rate slightly decrease. The tensile strength of pure CH–GE films was 24.4 ± 0.03, and it increased to 25.8 ± 0.05 MPa upon the addition of 0.0075% of AgNPs. The real-time application of the films was tested by evaluating the shelf-life existence of carrot pieces covered with the composite films. The composite film containing AgNPs becomes effective in lowering bacterial contamination while comparing the plastic polyethylene films. In principle, the synthesized composite films possessed all the ideal characteristics of packaging material and were considered biodegradable and biocompatible food packaging material and an alternate option for petroleum-based plastics.

Due to the impact of the Covid-19 pandemic, the usage of numerous protective face masks has faced an explosion in demand around the world. Therefore, the need to reduce the environmental pollution caused by disposable single-use face masks has become vital. Recently, alternative raw material solutions have been discussed to eliminate the consumption of single-use plastics. Within this research, gelatin nanofibers were fabricated via centrifugal spinning technique, and filtration media were investigated in terms of air permeability and filtration efficiency. In addition, morphological properties were examined with scanning electron microscopy. Fabricated fibers have a changing average diameter range from 232 to 778 nm, and targeted 95% filtration efficiency was achieved in several compositions. It was proven that biodegradable gelatin nanofibers could be a sustainable alternative for disposable N95 respiratory filters.

Research background. Microbial contamination in food products is one of the significant causes of food spoilage and foodborne illnesses. The use of active packaging films incorporated with antimicrobial agents can be a measure to extend food quality and shelf life. Nevertheless, synthetic antimicrobial agents such as silver, copper, titanium, and zinc in the packaging films raised concerns among consumers due to toxicity issues. Experimental approach. The current study aimed to develop biodegradable gelatine-based edible films incorporated with microcapsules of Clitoria ternatea-derived anthocyanin as a natural antimicrobial agent. The impact of anthocyanin microcapsule incorporation on the morphology, thermal, mechanical, water vapor barrier, and physicochemical properties of the gelatine films were evaluated in this study. The effectiveness of the developed films against foodborne pathogens and their application for perishable food protection again microbial spoilage were also studied. Results and conclusions. The results show that incorporating anthocyanin microcapsules enhances the gelatine film physical and mechanical properties by increasing the thickness, tensile strength, Young's modulus, and elongation at break of the films. SEM analysis revealed that the films surface morphology with anthocyanin microcapsules exhibit a homogeneous and smooth surface texture compared to the control. The thermogravimetric analysis also showed a slight improvement in the thermal properties of the developed films. Agar well diffusion assay revealed that the developed films exhibit significant inhibition against a broad-spectrum of bacterium. Furthermore, the films composed of gelatine anthocyanin microcapsules significantly reduced the total viable count of microorganisms in the bean curd at the storage time interval of 12 days compared with the control films. Novelty and scientific contribution. Increasing global awareness for healthy and safe food with minimal synthetic ingredients as preservatives has sparked the search for use of antimicrobial agents of natural origins in active food packaging material. In this study, a safe and effective active packaging film was developed using the environmental friendly biopolymer, gelatine films incorporated with microcapsules of Clitoria ternatea-derived anthocyanin as a natural antimicrobial agent. This study demonstrated that such a method not only be able to improve the film physical properties but also significantly prolong the shelf life of food products from microbial spoilage.
