Abstract
This disclosure refers to the fabrication of an active oxygen-absorbing compound composed of a sodium erythorbate and a non-organic salt of a transition metal encapsulated through the sol-gel method in a silica matrix. This compound can be part of the package's structure for oxidation-sensitive products or contained in the surrounding atmosphere to decrease the oxygen concentration. This application describes the method for the fabrication of the oxygen-absorber, as well as its encapsulation and incorporation in polymeric matrixes.
