“…However, pure CS film is deficient in the good barrier capacity, potent antibacterial activity, and antioxidant ability, which restricts its practical applications in the food packaging industry [ 22 ]. The addition of Carica papaya seed essential oil, in which the BITC was the predominant constitute, into the CS/polyvinyl alcohol blend film has been corroborated to not only exhibiting excellent UV−blocking capacity but also favorable antibacterial efficacy [ 23 ]. Despite the CS/κ−carrageenan composite film incorporating AITC still presenting a mild pungent smell, it was useful to repress the growth of Campylobacter jejuni inoculated on the chicken meats and prolong the shelf−life [ 24 ].…”

A bioactive packaging material based on chitosan (CS) incorporated with benzyl isothiocyanate (BITC) and α−cyclodextrin (α−CD) was fabricated to evaluate its preservative effects on fresh beef stored at 4 °C for 12 d according to the quality analysis. The Fourier-transform infrared (FTIR) spectrum revealed that the major structural moiety of BITC was embedded in the cavity of α−CD, except for the thiocyanate group. FTIR and X-ray diffraction analysis further verified that intermolecular interactions were formed between the BITC−α−CD and CS film matrix. The addition of BITC−α−CD decreased the UV light transmittance of pure CS film to lower than 63% but still had enough transparency for observing packaged items. The CS−based composite film displayed a sustainable antibacterial capacity and an enhanced antioxidant activity. Moreover, the total viable counts, total volatile base nitrogen, pH, thiobarbituric acid–reactive substances, and sensory evaluation of the raw beef treated with the CS−based composite film were 6.31 log colony-forming unit (CFU)/g, 19.60 mg/100 g, 6.84, 0.26 mg/kg, and 6.5 at 12 days, respectively, indicating the favorable protective efficacy on beef. These results suggested that the fabricated CS−based composite film has the application potential to be developed as a bioactive food packaging material, especially for beef preservation.

At a time when food safety awareness is increasing, attention is paid not only to food and additives but also to packaging materials. Most current food packaging is usually made of traditional petroleum-based polymeric materials, which are not biodegradable and have adverse effects on the environment and health. In this context, the development of new non-toxic and biodegradable materials for extending the best-before date of food is receiving increasing attention. In addition, additives in packaging materials may migrate outward, resulting in contact with food. For this reason, additives are also seen as a transition from synthetic additives to natural extracts. Active extracts from animals and plants having good antioxidant and antibacterial properties are also beneficial for human health. It is indisputable that active extracts are ideal substitutes for synthetic additives. Polymer packaging materials combined with active extracts not only maintain their original mechanical and optical properties and thermal stability but also endow polymers with new functions to extend the shelf life of food. This review paper provides an overview of this promising natural extract-containing polymer-based active packaging, with a focus on plant essential oils (containing phenolics, monoterpenes, terpene alcohols, terpene ketones, and aldehydes), pigments (procyanidins), vitamins (vitamin B), and peptides (nisin). In particular, this paper covers the research progress of such active extracts, in single or compound forms, combined with diverse polymers (mostly biopolymers) for food packaging applications with particular focus on the antioxidant and antibacterial properties of packaging materials.

“…Seeds have an effective antibacterial property against Escherichia coli, Salmonella species and Staphylococcus aureus infections. Some antihelminthic and anti-amoebic activities have also been put in evidence according to Bouanga-Kalou et al (2011), He et al (2017), Muhamad et al (2017), andYi et al (2022). The fundamental reasons for papaya seeds use as medicine are both poverty, which limit millions of people to conventional medicines, and the increase of antibiotic resistance against conventional drugs (Somda et al, 2021;Somda et al, 2023).…”

Carica papaya seeds have been used as traditional medicine. This study aims to determine the phytochemicals of papaya seeds essential oils their antimicrobial properties. Polyphenolic content and antioxidant properties were determined with standard methods. GC-MS was used to analyze chemical compounds. Antimicrobial properties were performed using agar diffusion method. MICs, MBCs and MFCs were established based on broth dilution methods. The results shown an average content of polyphenol compounds and antioxidant activity of 95.49 µg GAE /100 mL and 5569.06 µg AEAC/100 mL respectively. A total of 11 phytochemical compounds were identified and, Isothiocyanatomethyl (97.27%), Benzyl isocyanate (0.55%), Benzyl nitrile (0.43%)11,13-Tetradecadien-1-ol (0.28%) and Thioura, N, N'-bis (phenylmethyl) (0.26%) are major compounds. The essential oils were effective against Candida albicans, Candida spp, Escherichia coli, Salmonella spp, Shigella spp, Staphylococcus aureus and standards strains such as C. albicans 10231 S. aureus ATCC 08275, Salmonella typhimurium ATCC 14028, E. coli ATCC 25922 and E. coli ATCC 8739. Fungi MICs were from 0.16 to 0.38.10 -2 mg.mL while MFCs were between 0.31 and 0.78 10 -2 mg.mL. Bacteria MICs are from 0.09 to 6.25 while MBCs varied from 0.2 to 12.5 mg.mL. These essentials oils are possible improved traditional medicine against enterobacteria.
