Multifunctional betanin nanoliposomes-incorporated gelatin/chitosan nanofiber/ZnO nanoparticles nanocomposite film for fresh beef preservation

Abstract

The objective of this study was to fabricate betanin nanoliposomes incorporated gelatin/chitosan nanofiber/ZnO nanoparticles bionanocomposite film (G/CH NF/ZnO NPs/B NLPs) and investigate its effects on the preservation of fresh beef. The scanning electron microscopy image of nanocomposite film displayed a good inter-connective porous morphology. Fourier transform infrared and X-ray diffraction analysis confirmed the formation of new hydrogen bonds and enhanced crystallinity through the addition of CH NF, ZnO NPs, and B NLPs. The G/CH NF/ZnO NPs/B NLPs film exhibited satisfactory mechanical properties and high surface hydrophobicity (water contact angle = 92.49 ± 3.71°). The incorporation of ZnO NPs and B NLPs in the nanocomposite film provided high antibacterial activity and DPPH inhibition activity (53.02 ± 3.26%). The growth of inoculated bacteria, lipid oxidation, and the changes in the pH and color quality of the beef samples were controlled by packaging with the fabricated film. In conclusion, the G/CH NF/ZnO NPs/B NLPs nanocomposite has a high potential for meat preservation

Whey protein isolate‐based films incorporated with nanoemulsions of orange peel ( Citrus sinensis ) essential oil: Preparation and characterization

“…The growing consumption of plastics has led the authorities to be aware of the importance of replacing them with biodegradable ones (Almasi et al, 2020; Hosseini & Gómez‐Guillén, 2018). This is mainly because the chemically synthesized polymeric films show seriously notable disadvantages, in terms of recycling, petrochemical‐base, and environmental effects; limiting their use in packaging applications (Amjadi, Nazari, et al, 2020; Carpiné et al, 2015). Whey protein isolate (WPI) is one of the most frequently used biopolymers in the film preparation field (Aziz & Almasi, 2018).…”

Polysaccharide-Based Packaging Functionalized with Inorganic Nanoparticles for Food Preservation

“…Those results were associated with the ability of the hybrid film to inhibit the microbial growth (total viable count of 4 log CFU/g) and maintain the pH values (5.8) in the meat product than the uncoated sample (total viable count >7 log CFU/g and pH of 7.5), retarding the raw meat deterioration. Similarly, Amjadi et al [47] informed that fresh beef coated with a gelatin-chitosan-zinc oxide-betanin liposome hybrid composite was microbiological (S. aureus 2.63 log CFU/g and E. coli 3.83 log CFU/g) stable and reduced changes from lipidic oxidation (0.71 mg malondialdehyde/kg (MDA)), pH (6.27), and color attributes during 16 days at 4 • C than uncoated beef (S. aureus 5.26 log CFU/g, E. coli 6.76 log CFU/g, 1.23 mg of MDA/kg and pH of 7.20, respectively) or chitosancoated samples (S. aureus 5.76 log CFU/g, E. coli 6.13 log CFU/g, 1.50 mg of MDA/kg and pH of 7.51, respectively). These results were attributed to the antimicrobial and antioxidant properties of the hybrid film that prevented the myoglobin oxidation and accumulation of metmyoglobin, associated with the zinc oxide and betanin liposomes.…”
