In the preservation of water-rich foods, especially meat, spoilage can occur due to bacterial contamination and oxidative degradation. This study aimed to determine the structural characteristics and synthesis of the chitosan-graft-pomegranate extract (CS-g-POM) hydrogel using a cost-effective and biobased method to develop antibacterial and antioxidant pads. Pomegranate extract is used to fabricate covalently and noncovalently interconnected chitosan hydrogel networks. Several characterization methods, such as Fourier transform infrared spectroscopy, thermogravimetric analysis, field emission scanning electron microscopy, atomic force microscopy, and rheological analysis, confirmed the successful design of the produced hydrogel. The freeze-dried CS-g-POM hydrogel had a swelling ratio of 373%, 614%, and 508.5% at pH 5, 7.4, and 10, respectively. FE-SEM images showed the porous hydrogel, which confirmed the cross-linking process. The addition of pomegranate extract increased the phenolic content, resulting in a DPPH radical scavenging activity of 50.20%. The hydrogel also had good antibacterial properties, with the inhibition zones against Escherichia coli and Staphylococcus aureus measuring 18 ± 1 mm and 12 ± 1 mm. The CS-g-POM hydrogel plays a crucial role in moisture absorption in water-rich foods such as meat due to its high degree of swelling and could be used as an antibacterial absorption pad.

As the human population increases very rapidly, it is necessary to develop an efficient biodegradable packaging material to increase the shelf life of food, guarantee food safety, and reduce spoilage from extreme conditions. To overcome all of these problems, herein, we synthesize smart sensing strips and antimicrobial active food packaging films to prevent molding. For smart sensing of food spoilage, covalent organic frameworks (COFs) were synthesized from 2,4,6-triformylphloroglucinol (TFP) and p-phenylenediamine. Thereafter, COF was incorporated into a sodium alginate polymeric material to obtain sensing strips with highly colorimetric response and augmented mechanical properties. Smart sensing strips were demonstrated on packaged poultry meat. The sensing strips are highly pH-responsive and color changes according to the pH of the surrounding. Sensing responses of COF were also studied for the biogenic amines that evolve during the spoilage of meat using cyclic voltammetry. The SA/COF film was characterized through different techniques including atomic force microscopy, field emission scanning electron microscopy, Brunauer−Emmett−Teller, energy-dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy, and powder X-ray diffraction. In addition to this antimicrobial citral was incorporated into the SA/COF film to prepare an active packaging film, which reduces food spoilage from high humidity, molding, and high-temperature conditions. The active packaging film was applied to the peanuts to avoid mold formation, which increases their shelf life and reduces food wastage. Based on the above research, we designed a polymeric film for smart sensing and packaging of food.

SummaryOne recent trend in the food industry is using natural antioxidants and antimicrobials as additives for developing multi‐functional packaging. In this study, phenolic compounds from patawa (PEP), a neglected Amazon palm tree, were extracted and encapsulated in nanoparticles based on acetylated cashew gum polysaccharide (acCGP) and chitosan (CS) using a nanoprecipitation technique. The primary objective was to evaluate the antioxidant activity and antibacterial properties of PEP and acCGP/CS@PEP. Results from HPLC‐MS showed that PEP is mainly composed of epicatechin, naringenin and rutin. acCGP/CS@PEP nanoparticles showed a spheric and smooth microstructure, observed with 40.1% PEP encapsulation into the nanoparticles. The main encapsulated phenolics were luteolin, quercetin and epicatechin. Also, FTIR spectroscopy, X‐ray diffraction and differential scanning calorimetry analyses evidenced the success of PEP encapsulation. Results from antioxidant activity evidenced that acCGP/CS@PEP has a DPPH scavenging activity 45‐fold higher than the unencapsulated PEP, a 5‐fold higher ferric reducing power and 20‐fold higher antioxidant potential against ABTS. Similarly, acCGP/CS@PEP had higher antibacterial activity against Escherichia coli (MIC = 2.24 mg mL−1), Salmonella enteritis (MIC = 4.48 mg mL−1) and Staphylococcus aureus (MIC = 4.48 mg mL−1). Analysis by SEM evidenced that acCGP/CS@PEP had a potent destructive effect with disruption of the bacterial cell membrane and liberation of cytoplasmic content. These findings demonstrated that PEP could be efficiently encapsulated in acCGP/CS nanoparticles, and this strategy could improve the efficiency of PEP as a bioactive compound for developing active packaging.
