Methods and systems for treatment of grain in a storage container using ozone may be used for treating grain for toxins, insects, mold, and/or odor. Downdraft methods for applying high concentrations of ozone to grain in a storage container treat grain without generating ozone-related objectionable odors or with generation of only minimal ozone-related objectionable odors. A method for downdraft ozone treatment of grain with minimal generation of ozone-related objectionable odors involves providing a negative air pressure at a bottom of a volume of grain in a storage container. A high ozone concentration is generated in air above an upper surface of the volume of grain. The ozone is drawn down into the volume of grain using the negative air pressure for a treatment time sufficient to effectively treat the grain without causing significant ozone-related commercially-objectionable foreign odors in the grain.

The present disclosure relates to methods and devices for controlling arthropods, including insects and arachnids in an environment. The methods generally comprise: generating a near-ideal gas Purified Hydrogen Peroxide Gas (PHPG) that is substantially non-hydrated (e.g., in the form of water in solution or water in solution or water molecules bonded by covalence, van der Waals forces, or London forces) and substantially free of e.g., ozone, plasma species, and/or organic species; and directing the gas comprising primarily PHPG into the environment such that the PHPG acts to control arachnids in the environment. In certain aspects, the arachnids may be totally or partially killed.

The present disclosure relates to an air modifying device for extending the shelf life of a fresh product and to methods of extending the shelf life of fresh products. Certain embodiments of the present disclosure comprise an air modifying device for extending shelf life of a fresh product. The device comprises a hollow body, one or more means for moving air or a gas through the hollow body, a surface within the hollow body, the surface comprising a metal oxide, and a source of UV light within the body to direct UV light onto the surface comprising the metal oxide, wherein irradiation of the metal oxide with the UV light modifies the air or gas moved through the device so that release of the modified air or gas from the device into the atmosphere around the fresh product extends the shelf life of the fresh product.

Provided herein is a degassing valve for a foodstuff product including a valve body, a one-way valve element positioned on the valve body, and a filter associated with said valve body wherein the filter is configured to facilitate the passage of a gas. The gas may be selected from the group consisting of carbon dioxide, oxygen, nitrogen, and methane. Additionally, the gas may be a longer molecular chain gas that comprises the aroma of the product. The filter of the valve body may include activated charcoal, an activated charcoal mixture or a combination thereof. In some embodiments, the foodstuff product comprises breadcrumbs, spices, or other flavorful dry foods, the aroma(s) of which can provide an important marketing benefit.

Disclosed are a disinfection and sterilization apparatus and method for a refrigerated container transportation system. The disinfection and sterilization apparatus comprises a to-be-treated waiting area, a disinfection and sterilization system, a treatment waiting area and a central control system, wherein a first prompter is arranged in the to-be-treated waiting area; the disinfection and sterilization system comprises a disinfection and sterilization bin, a vacuumizing device and an ozone supply device; a disinfection and sterilization bin inlet and a disinfection and sterilization bin outlet are respectively formed in the left side and the right side of the disinfection and sterilization bin; the top of the disinfection and sterilization bin is provided with a detaching and hanging device for detaching or hanging a refrigerated container and a transportation vehicle; a second prompter is arranged in the treatment waiting area; and the central control system is connected with the first prompter, the disinfection and sterilization bin inlet, the disinfection and sterilization bin outlet, the detaching and hanging device and the second prompter through data transmission lines.

Methods of manufacturing a light-activated powder are provided which provide solid-state generation and release of chlorine dioxide without detectable amounts of any toxic by-products such as chlorine gas, chlorites, or chlorates. The powder need not be exposed to moisture, relative humidity, or an acid before or during exposure of the powder to visible light to generate the gas. The powder can also be prepared under conditions that minimize or prevent decomposition or oxidation of sodium chlorite or premature light activation of the powder during the manufacturing process to maximize its activity.
