Active Packaging Systems Based on Metal and Metal Oxide Nanoparticles

Mechanical properties, sustained release, and oxygen scavenging properties of nanocomposite films loaded with bimetallic nanoparticles (Fe2O3/TiO2) in extra virgin olive oil

“…Therefore, applying sustained release structures can solve many of the limitations caused by the formation of local aggregations of nanoparticles (Vieira et al, 2022). Various studies have been conducted on the synthesis of bimetallic nanoparticles using different methods, which points to the ability of these nanoparticles to scavenge oxygen (Babu et al, 2023;Ballesteros et al, 2022;Kamli et al, 2021;Mohan et al, 2021). Mohan et al (2021) synthesized silver-palladium (Ag/Pd) bimetallic nanoparticles by a green process using Catharanthus leaf extract.…”

Multifunctional Properties of PBAT with Hemp (Cannabis sativa) Micronised Fibres for Food Packaging: Cast Films and Coated Paper

“…Improving the functional properties of the materials with active and smart systems and the use of biodegradable packages in specific applications are approaches that can contribute to decrease food and plastic waste [7]. Polybutylene adipate terephthalate (PBAT) and its blends and composites are promising biodegradable polymers due to their good resistance to water and mechanical flexibility compared with other biopolymers such as polylactic acid (PLA) and poly(butylene-co-succinate) (PBS) [8].…”

Zn and Zn-Fe Nanostructures with Multifunctional Properties as Components for Food Packaging Materials

“…Thus, to achieve such multifunctional requirements, researchers and industries have focused on the development of novel nanomaterials compatible with food products. Some examples of these are metallic nanoparticles, which have been explored as antibacterial agents [1][2][3], antioxidants [4][5][6], catalyzers [7,8], and photocatalytic and scavenging mediators [3].…”

“…Nanoparticles (NPs) of transition metals have demonstrated potential in technological applications compared with macroscopic materials, particularly when used in food packaging, enhancing the mechanical properties and controlling the biodegradability of the produced materials [3,9,10]. Moreover, studies have confirmed the benefit that such NPs bring to consumers, since the NPs contribute to extending the shelf life of food, ensuring better traceability and providing reinforced protection [11,12].…”

“…The morphology of NPs is another factor that strongly influences their multifunctional properties, and therefore, a convenient production method for NPs needs to be chosen. NPs are usually prepared using physical, chemical, and biological methods [25][26][27], which can influence their geometry, aspect ratio, and distribution [3,28,29] as well as their composition and toxicity. However, the incorporation of the nanoparticles into packaging materials is a nontrivial process, dramatically reducing the performance of the nanostructures because of agglomeration [30].…”
