Oxygen scavengers impregnated in porous activated carbon matrix for food and beverage packaging applications

The purpose of this research study was to evaluate two novel oxygen scavengers based on lecithin and sodium erythorbate using a supercritical fluid methodology to impregnate it in a porous matrix. A zero-order model was used to describe the oxygen absorption kinetics of these absorbers suitable for food and beverage packaging applications. Both oxygen scavengers were competitive compared to commercial available technologies. The absorption rate of lecithin was advantageous compared to erythorbate and other scavengers. This research was foreseen in a prospective study on flexible plastic packaging that it was carried out with the participation of 20 companies.
