“…The peak intensity of the same band was also enhanced, further confirming the existence of VK 3 molecules in the mixture. New peaks in the region at around 1548–1120 cm –1 also appeared, referring to the −C–C stretch in the aromatic ring of the VK 3 molecule in the EVA/VK 3 blends …”

“…New peaks in the region at around 1548−1120 cm −1 also appeared, referring to the −C−C stretch in the aromatic ring of the VK 3 molecule in the EVA/VK 3 blends. 33 The pure EVA film is transparent, and the transparency of the films decreases with the increase of menadione content in the mixtures. Figure 1e displays UV−vis transparency measurements of the resultant films.…”

“…The main challenge in development of antibacterial food package materials is the identification of novel, naturally occurring food grade compounds as efficient light-activated sensitizers. , Bio-based agents have gained tremendous applications in the sustainable and biodegradable food packaging industry due to their renewability, availability, biodegradability, and nontoxicity. , However, the application of natural photosensitizers faces challenges in fulfilling the requirements of food packaging applications due to their low ROS production and chemical instability toward light irradiation . In recent years, investigations into green functional materials have suggested that natural vitamin Ks (VKs) may be capable of generating ROS effectively in various solvent systems under light irradiation .…”

The emerging infectious diseases have created one of the major practical needs to develop active packaging materials with durable antibacterial and antiviral properties for the food industry. To meet this demand, the development of new technologies applicable to food contact surfaces is highly desired but challenging. The recent discovery of the photoactive properties of vitamin K (VK) derivatives has raised great expectations as promising candidates in functional film development due to the generation of biocidal reactive oxygen species (ROS) by these compounds. Inspired by the excellent photoactivity of one of the light-stable VK derivatives, menadione (VK 3 ), under visible daylight irradiation, we demonstrate a protocol for the fabrication of daylight-mediated biocidal packaging materials by incorporating VK 3 into a poly (ethylene-co-vinyl acetate) (EVA) matrix. The VK 3 (i.e., 1−5% w/w) incorporated EVA films successfully demonstrated the production of ROS and antibacterial and antiviral performance against Escherichia coli, Listeria innocua, and T7 bacteriophage, respectively, under daylight exposure conditions. The results revealed that the addition of a proper percentage of VK 3 significantly enhanced the ROS productivity of the films and created a novel daylight-induced microbial killing performance on the films. The biocidal functions of the films are long-lasting and rechargeable when exposed to light repeatedly, making them a viable contender for replacing currently available conventional packaging films.

“…PDI can be described as a process in which reactive oxygen species (ROS) that are toxic to microorganism are formed. To achieve this, three non‐toxic agents are combined: molecular oxygen, light and a photoactive molecule called photosensitizer 3,4 . The combination of this three agents under controlled conditions leads to the generations of ROS such as singlet oxygen ( 1 O 2 ), hydrogen peroxide (H 2 O 2 ), superoxide ions (O 2 •‐ ) and hydroxyl radicals (OH • ).…”

“…The photosensitizer molecules in the ground state (S 0 ) absorb energy in the form of photons from a light source in the appropriated wavelength; this allows one electron to move to a higher energy level (S 1 ) while keeping the parallel spin from the ground state. In the right conditions, an intersystem crossing occurs and the electron in the S 1 changes its spin, creating an excited triplet state (T 1 ) which can react with oxygen molecules creating ROS 4–9 …”

Background: Aspergillus niger is one of the most common fungal contaminants of food products, leading to several economic losses on fruit, vegetables and other food products during storage. Over the years, several new techniques have been developed to control fungal growth, including photodynamic inactivation, in which excitation of a photosensitizer in the right wavelength leads to ROS production and microbial death.Results: On this paper, curcumin was used as a natural photosentitizer against A. niger spores. Nanoemulsions were used in order to encapsulated curcumin and increase its water solubility. Results showed that spores inhibition could reach up to 80% after 3 min of irradiation while values for un-encapsulated curcumin were around 30%. Conclusion:Results presented show that nanoemulsions could be use to enhance the photoinactivation properties of curcumin, against fungal spores from A. niger. This type of process can be use for food decontamination and preservation.

Food packaging that impedes microbial growth and can be safely used is critical to attenuate food spoilage. Herein, a green berberine/phytate salt (BPA) is successfully synthesized and aggregated in polyvinyl alcohol (PVA) film to impart fluorescent and photodynamic antimicrobial properties. Compared to berberine hydrochloride (BHL), BPA exhibited stronger fluorescence because intramolecular motions and intermolecular π–π accumulation of BHL are restricted by phytic acid (PA). Molecular dynamics simulation indicate that aggregation of BHL and PA formed through electrostatic interactions in the PVA matrix due to the change of the binding energy during the drying process. With increasing BPA content, the films exhibited increased ultraviolet, water vapor, and oxygen barriers and fluorescent properties, but reduced tensile strength and elongation at break. After radiated, PVA‐BPA9 film showed the highest antimicrobial rates against Staphylococcus aureus, Escherichia coli, P. citrinum, and Aspergillus niger reached 100%, 100%, 86.14%, and 66.24%, respectively, due to the increased reactive oxygen species production. The total number of microbial colonies in cooked chicken and oranges packaged by PVA‐BPA9 film with irradiation ARE 87.54% and 29.21% of those by PVA film. The findings indicate a new and feasible strategy to obtain a green photodynamic‐mediated film for safe and effective food packaging.
