A fresh drawer and a refrigerator using same. The fresh drawer comprises: a drawer body, wherein a storage chamber for storing food is provided inside the drawer body, and the storage chamber is of an openable sealed structure; a gas supply mechanism, used for providing fresh-keeping gas for the storage chamber; and a pressure balancing mechanism, used for balancing air pressure inside the storage chamber. In the fresh drawer and the refrigerator using same, air in an inner storage chamber is replaced with fresh-keeping gas such as nitrogen and oxygen, to provide a modified atmosphere for a food storage space, such that the shelf life of food can be greatly extended.

The present invention aims at dissolving hydrogen gas in a liquid and maintaining the solubility of the hydrogen gas in the liquid at a high state. A sealing bag 1 that dissolves hydrogen gas in a liquid by being put into the liquid includes a hydrogen permeable film that can permeate hydrogen gas that is sealed and filled in the sealing bag to outside. By sinking this sealing bag 1 into the liquid in advance, the hydrogen gas that is permeated through the hydrogen permeable film is dissolved in the liquid. Furthermore, since the hydrogen gas is continuously permeated little by little through the hydrogen permeable film, the solubility of the hydrogen in the liquid can be maintained at a high state.

A method for decontaminating articles having porous outer surfaces. The method includes providing a decontamination chamber; conveying the articles through the decontamination chamber at a predetermined speed wherein the speed is selected such that the articles are disposed in the decontamination chamber for a predetermined period of time; providing a source of sterliant vapor, the source providing the sterilant vapor at a temperature within a predetermined acceptable temperature range and at a concentration within a predetermined acceptable concentration range; conveying a sterilant vapor from the source of sterilant vapor to the decontamination chamber; and exposing the articles to the sterilant vapor. The predetermined period of time and the predetermined acceptable concentration range of the sterilant vapor are selected such that the sterilant vapor does not penetrate the porous outer surfaces of the articles.

A method for controlling the concentration of a gas in a crisper drawer (100): by capturing the concentration of a freshness-preserving gas in a storage chamber (10) and comparing with a preset threshold, determining whether to feed the freshness-preserving gas into the storage chamber (10), or employing a timed feeding method to control whether to feed the freshness-preserving gas into the storage chamber (10). The method selectively feeds the fresh-preserving gas into the storage chamber (10), thus controlling the concentration of the freshness-preserving gas in the storage chamber (10) to be kept above a target concentration, significantly extending the time during which food is kept fresh, and at the same time, taking into consideration the economy of using the freshness-preserving gas.

The present disclosure relates to a method for treating an object with chlorine dioxide gas, comprising contacting the object with chlorine dioxide gas while exposing the object to less than 1000 lux of light. The disclosed method minimizes chlorine containing residue on the surface of the object. The object can be a raw agricultural commodity (RAC) such as a raw fruit or vegetable.
