Abstract
The production of an oxygen-absorbent composition is provided, having: (a) a porous silica encapsulation matrix; and (b) a composition containing an oxygen-absorbent compound selected from fatty acids, unsaturated esters or compounds containing same, and, optionally, a catalyst based on an inorganic salt of a transition metal, wherein the composition (b) is encapsulated in the porous silica matrix (a). The composition can form part of the structure of the packaging for oxidation sensitive products or be placed in the surrounding atmosphere to reduce the concentration of oxygen. A method for encapsulating the active compound or the active compound together with a catalyst, and subsequently incorporating same into polymer matrices is also provided.
