Abstract: Disclosed herein are an organic oxygen absorber and a preparation method thereof. The organic oxygen absorber is prepared by reacting each of an ascorbic acid compound and an oxygen absorption promoting material with porous silica powder, which has high adsorbability, at room temperature so as to be impregnated into the silica powder, and then mixing the impregnated materials with each others before filling into an air-permeable packaging material. The organic oxygen absorber does not influence an oxygen detector or the like, has high oxygen absorbability and is prepared with high efficiency.

Abstract: The present invention provides a packing structure including a theft prevention tag, in which an anti-theft electronic tag is mounted to a ventilating packing element having contained therein a food-preserving agent such as an oxygen-binding agent, a moisture-proofing agent, or a freshness-keeping agent, and the ventilating packing element is easily built in a product wrapper, so that the anti-theft electronic tag is prevented from being damaged with a malicious intention, thereby further ensuring safety and security of products or articles.

Abstract: The object of the present invention is to provide a bottle stopper configured to be used in re-sealing a mouth part of a bottle for containing a product which may cause a risk of easily being acidified due to the contact with oxygen, thereby safely and sustainably absorbing and eliminating oxygen introduced into the bottle. The bottle stopper according to the present invention is constructed such that the stopper main body fitted into the mouth part of the bottle to re-seal the mouth part of the bottle is formed with the accommodating space portion capable of receiving the oxygen absorber so that oxygen remaining in the bottle can be safely and sustainably absorbed and eliminated.
