Abstract
The present invention refers to the use of a surface-treated calcium carbonate-comprising material and/or magnesium carbonate-comprising material as oxygen scavenger; wherein the surface treatment agent is selected from the group consisting of ascorbic acid and/or salts thereof, gallic acid and/or salts thereof, unsaturated fatty acids and/or salts thereof, elemental iron, iron (II)-salts and iron (II)-comprising oxides, iron (II, III)-comprising oxides and mixtures thereof; and wherein the total weight of the surface treatment agent on the total surface area of the at least one calcium carbonate-comprising material and/or magnesium carbonate-comprising material is from 0.01 to 40 mg/m 2 , based on the at least one calcium carbonate-comprising material and/or magnesium carbonate-comprising material.
