An oxygen absorbent for use in oxygen absorption in the air is filled in a breathable package and sealed in a package such as food to absorb oxygen in the package to preserve the shelf life of the food. In order to increase the oxidation rate of iron in the process of absorbing oxygen, when the inorganic electrolytic substance is impregnated into the carrier, it is possible to increase the activity together with the moisture content of the carrier, thereby accelerating the oxidation rate of iron, The present invention relates to an oxygen absorbent having high water activity and a method for producing the same. The oxygen absorbent having high water activity of the present invention is prepared by mixing powdered iron powder with sodium chloride and calcium chloride as fine powders And an oxygen absorbent comprising a corrosion promoting iron powder and a carrier, The carrier is characterized by using amorphous porous silica obtained by calcining at a temperature between 400 and 850 ° C. The oxygen absorbent of high water activity of the present invention having the above-mentioned structure and the method of manufacturing the same according to the present invention can be produced by impregnating an inorganic electrolyte with amorphous porous silica having enhanced corrosion activity and iron oxide powder with enhanced water activity, Since the initial activity of water carried on the carrier is remarkably improved, oxygen in the wrapping paper can be initially removed in a large amount to improve the preservability of the food, thereby solving the problems in the prior art described above.본 발명은 공기 중의 산소흡수에 사용되는 산소 흡수제를 통기성이 있는 포장체에 충진하여 식품 등의 포장 내에 넣어 밀봉하여 포장지 내의 산소를 흡수하므로서 식품의 보존기간을 연장시키는 것으로, 철분의 산화반응을 이용하여 산소를 흡수하는 과정에서 철분의 산화속도를 높여주기 위하여 무기 전해물질을 담체에 함침할 때 담체의 수분 함유량과 함께 활성도를 높일 수 있게 하여 철분의 산화속도를 촉진시켜 포장지 내의 산소제거속도를 빠르게 높여줌으로써 식품의 보존기간을 증대시킬 수 있는, 수분 활성도가 높은 산소 흡수제 및 그 제조방법에 관한 것으로, 상기한 본 발명의 수분 활성도가 높은 산소 흡수제는 분쇄한 철 분말과 미분의 염화나트륨 및 염화칼슘을 혼합하여 만든 부식 촉진 철 분말과 담
