Title:
DEOXIDIZER
Document Type and Number:
WIPO Patent Application WO/2003/055336
Kind Code:
A1
Abstract:
A deoxidizer, characterized in that it comprises an iron powder and an ume charcoal prepared by carbonizing a seed of ume (Japanese apricot) containing a table salt. In the deoxidizer, the iron powder is oxidized with the aid of a salt component such as a table salt as a catalyst, to thereby absorb the oxygen in air. The great porosity of an ume charcoal results in a great contact area thereof with air, which leads to the enhancement of the efficiency of oxygen absorption. Further, an ume charcoal has moisture controlling capability, and thus can supply the moisture into the air around it necessary for the oxidizing reaction. As the seed of ume containing a table salt, use is suitably made of the seed of ume which is by-produced as a waste in the course of the processing of ume. The above deoxidizer further comprising a photocatalyst as an optional component has improved oxygen absorbing capability and also exhibits high deodorizing capability, and thus, can be suitably used in the fields of food, clothing, and the like. The above deoxidizer allows the effective use of an ume seed as a waste, and provides a novel deoxidizer which is excellent in performance capabilities such as oxygen absorption amount and oxygen absorption rate and also is capable of effectively diminishing the odor by a toxic gas or the like.
