Devices and methods for provided both an antimicrobial vapor such as hydrogen peroxide and/or peracetic acid and water vapor in an enclosed or partially enclosed space are described. The device and method provided is for the reduction or elimination of microbes from air and surfaces in contact with air within an enclosed or partially enclosed space using hydrogen peroxide or peracetic acid in the vapor phase and also provide for humidity from water vapor. The device and method are directed towards a release of an antimicrobial vapor and water vapor through a permeable container/barrier containing a matrix into which water and an antimicrobial vapor producing material are absorbed.

The use of a palladium-doped zeolite for the adsorption of volatile organic compounds is described wherein the zeolite has a CHA framework type and is polymer-bound. Such zeolites have been found to have particular utility as packaging materials for the adsorption of volatile organic compounds, such as those originating from organic matter.

An active package having LTA zeolites exchanged with palladium is described. This solution is capable to improve the quality of the gaseous atmosphere within the package itself, with particular reference to the presence of ethylene. This solution provides improved performance when the package is accidentally exposed to hydrocarbon vapors and provides benefits in terms of reliability in the ethylene control.

A dried food fresh-keeping packaging bag structure includes a packaging bag and a fresh-keeping device in the packaging bag. The fresh-keeping device includes a storage box. One side of the storage box is attached to an inner surface of the packaging bag. The storage box has a storage chamber filled with a preservative. One side of the storage chamber is formed with an outlet provided with a breathable film to block the preservative. An outside of the breathable film is provided with a sealing film to seal the storage chamber. One end of the sealing film extends to an outside of a mouth of the packaging bag to form a pull portion. When in use, the pull portion is pulled to tear the sealing film from the fresh-keeping device, so that the dried food product in the packaging bag is kept dry by the preservative.

Methods are provided for storing and preserving a cut or whole berry product, preferably so as to extend shelf life of the same. In one optional method, the berry product is placed in a product containing space of a storage container atop a platform of a support structure. The storage container includes an internal compartment having the product containing space. The support structure defines the platform for supporting the berry product. The internal compartment further includes a reservoir, configured to retain liquid, below the platform. The platform and/or support structure are configured to direct liquid exuded from the berry product to the reservoir. Optionally, the reservoir comprises an absorbent material for absorbing liquid in the reservoir

The invention relates to a sachet that absorbs ethylene or other gases for containers of fresh produce intended for the retail market which is formed by two sheets welded together at the edges (4), at least one of the sheets, for example, the bottom sheet (2), being made with a porous, water-repellent, breathable material and optionally combined with another sheet (3) of waterproof material, and ethylene-absorbing granules (5) contained therein to absorb gases or other volatile substances produced by fresh produce incorporated in small packages (6), said granules (5) consisting of a substrate impregnated with potassium permanganate or sodium permanganate at a high concentration of between 0.25% and 2%, optionally mixed with activated carbon, such that when the sachet (1) is in contact with moisture generated by the produce, the risk of spotting and contamination by the active ingredient is minimal and absorption efficiency is maintained.
