The disclosure discloses a method for killing A. Flavus spores by infrared radiation in coordination with essential oil fumigation, and belongs to the technical field of sterilization. The method is to treat A. Flavus spores by medium and short wave infrared radiation in combination with essential oil fumigation. The disclosure provides a method for killing A. Flavus spores by medium and short wave infrared radiation in coordination with essential oil fumigation. On the one hand, air residual heat and energy of medium and short wave infrared radiation are fully used to make a material heated up rapidly, and on the other hand, essential oil on the surface of the material penetrates the cell membrane of A. Flavus spores, and further damages protein on the membrane and internal organelles in combination with the heat effect. The process is easy in operation, low in energy consumption, pollution-free and high in sterilization efficiency, and can be used for purifying bulk grains.

Compositions and methods for generating ClO.sub.2 gas are disclosed. A composition that includes a chlorite salt is activated by exposure to ultraviolet light. After an optional storage period, the composition is then exposed to moisture, resulting in the generation of ClO.sub.2 gas. Exemplary compositions include polymers in which the chlorite salt is dispersed. The polymers may be used to form films that can be used to package, e.g., food products, pharmaceutical products, medical devices, and/or laboratory devices. Upon exposure to ultraviolet light and moisture, the packaging releases controlled quantities of ClO.sub.2 gas, which may disinfect and/or deodorize the packaged device or product.

The treatment unit includes an evaporation device including a gas circulation pipe, and a material with a large specific surface filling an evaporation section of the circulation pipe; a device for circulating the gas through the circulation pipe; a liquid impregnating the material with a large specific surface, the liquid containing at least one product or a mixture of volatile biocide and/or phytoprotective products, with a boiling temperature between 130 and 280° C., the material with a large specific surface having a liquid retention capacity greater than 50 L/m.sup.3 of material with a large specific surface at 20° C.; a recharging device, arranged to re-impregnate the material with a large specific surface with liquid or to replace the spent material with a large specific surface with a new material with a large specific surface impregnated with liquid.

A method for treating a substrate with a volatile liquid, crop-preservative formulation includes transporting a predetermined quantity of the formulation from a reservoir to an injection device and applying the predetermined quantity to the substrate. The substrate may thereafter be in proximity to a crop to be treated by the vapor from the formulation. The substrate is most conveniently a portion of a container in which the crop is stored or shipped.

The present invention relates to novel freeze-dried confection compositions, and methods for making the same. There is a long-felt need for nutritious snacks that are preserved for long periods without preservatives and having acceptable flavor. The freeze-dried confections of the present invention comprise are composed of freeze-dried raw fruits and vegetables and other natural ingredients with no preservatives, and prepared in such a way that they can be preserved at room temperature for many years.

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.
