Novel oxygen scavenger screw-cap for shelf-life improvement in virgin olive oil packaging during storage

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

“…The results of the evaluation of oxidative indices caused by olive oil showed that the cobalt oxalate nanoparticles inhibit oxygen. They stated that by applying cobalt oxalate nanoparticles, on the one hand, the formation of primary oxidation products is delayed, and on the other hand, the destruction of primary products and the production of secondary oxidation products are also disrupted, and all these factors cause a delay in the oxidation process of olive oil (Pourshahbazi et al, 2022). Also, Hidayah et al (2020) used iron powder as an oxygen absorber in active packaging to increase the oxidative stability of fish oil.…”

“…These findings are consistent with the results of other researchers in terms of oxidation control by composite nanoparticles. Pourshahbazi et al (2022) designed an active packaging based on polyethylene terephthalate and cobalt oxalate nanoparticles as an oxygen inhibitor to increase the shelf life of olive oil. The results of the evaluation of oxidative indices caused by olive oil showed that the cobalt oxalate nanoparticles inhibit oxygen.…”

“…However, one of the most interesting effects of metal based nanoparticles is their antioxidant activity due to their ability to inhibit oxygen (Adeyemi & Fawole, 2023). Antioxidants are incorporated into packaging systems in various forms, mainly including standalone bag packages, adhesive labels, adsorption/physical coating on the surface of packaging materials, blending in packaging polymer matrices, multilayer films, and immobilization (Azevedo et al., 2022; Pourshahbazi et al., 2022).…”

Accelerating the Oxygen Scavenging of Natural Rubber with Food-Grade Catalysts Impregnated on Silica-Based Platform

“…4 Oxygen scavengers are an active packaging system that enhances food quality by removing oxygen from the package headspace. 5 These scavengers possess the capability to lower oxygen levels to less than 0.01%, surpassing the residual levels of 0.3−3.0% achievable through the modified atmospheric packaging (MAP) technique. 1,6 With these benefits of the varieties of oxygen scavengers available today, there are many possible combinations, viz., metal powder, palladium, enzymes, gallic acid, α-tocopherol, L-ascorbate and pyrogallol.…”
