Oxygen absorbent and its use

Abstract

Abstract The present invention relates to oxygen absorbent and its use. In the state of the art there have repeatedly been problems with keeping packaged foodstuffs fresh and protecting medicaments from oxidation. The invention provides a remedy for this in that it provides an oxygen absorbent, namely based on a combination of an absorbent in the form of porous, precipitated silica as water carrier, characterised by a mixture in which the organic substances are formed by glucose and glucose oxidase, and where the particle or pore interstices of the precipitated silica and other solids are kept at least partially free of water. To achieve a free-flowing mixture, it is beneficial if at least 40 % of the particle or pore interstices are kept free of water, it being possible for this value to be regarded as guideline. At the same time, calcium carbonate, calcium hydrogen phosphate or magnesium carbonate or sodium bicarbonate are used as absorbent or reaction accelerator. <??>Furthermore, the invention makes it possible to use a bag or a tablet or pellets in mini containers containing an oxygen absorbent according to one or more of the preceding claims for keeping foodstuffs fresh.
