摘要:
A manufactured dry ice product containing ozone entrapped or absorbed on said dry ice. The dry ice product can be used to chill and preserve food products and provides the added benefit of ozonation of the food product to kill bacteria. Novel processes for ozonating liquid and solid CO2 are provided.
摘要:
The use of ozone in liquid carbon dioxide as a sterilant for use in aseptic packaging. The low temperature provided by liquid CO2 further eliminates microbiological hazards. The combination of these two chemicals will enable the aseptic industry achieve higher process efficiencies and improved sterilization without the drawbacks currently seen with the use of hydrogen peroxide.
摘要:
Products and methods for treating or sanitizing a target item to reduce or eliminate biological microorganisms in or on the target item. The target item is contacted with a moist sanitizing gas mixture to effectively reduce the presence of biological microorganisms without adversely affecting the quality of the target item. The moist sanitizing gas mixture of the invention is particularly useful for treating food products. The moist sanitizing gas mixture of the current invention may be formed by humidifying a dry gas and then contacting the target item with the humidified gas containing a sanitizing agent. Furthermore, the invention provides for chilling the target item, particularly food items, before exposure to the moist sanitizing gas mixture to preserve the fresh appearance, taste, and aroma of the target item.
摘要:
Methods for treating, and/or cooling of a target item to reduce or eliminate biological microorganisms in or on a target item. The treating agent of the invention is particularly useful for treating food products, food storage, and food transportation devices as well as treating water, or other target objects. A treating agent containing a sanitizing agent entrapped by or absorbed in or on a cooling agent is used when processing, transporting, displaying, or storing of target items. The treating agent can be used to chill and preserve target items while providing the added benefit of sanitizing the target item. The novel processes of the current invention provide for using a treating agent to process, store, or package target items using a treating agent containing a cooling agent, such as solid carbon dioxide (“dry ice”), and a sanitizing agent, such as ozone.

摘要:
Dry ice blasting using dry ice pellets having additives, such as antimicrobial compounds, disinfectants, surfactants, and odorants. Additives are incorporated into solid carbon dioxide by any variety of processes. The additives are selected on the basis of cleaning or olfactory effects.
摘要:
Embodiments of the invention generally provide a treating agent comprising an antimicrobial carrier chemical and a cooling agent to chill and sanitize food products during processing steps, wherein the antimicrobial carrier chemical is in liquid or solid form.
摘要:
The present invention is a cryogenic subterranean fracturing fluid, comprising a liquefied industrial gas and a viscosity increasing additive. The liquefied industrial gas may be liquefied carbon dioxide, liquefied nitrogen, or a blend of the two. The liquefied industrial gas mixture should be substantially free of water. In this context, substantially free of water means less than 10% water by volume, or preferably less than 5% water by volume. In addition to the viscosity increasing additive, a proppant may be added to the fracturing fluid. In addition to the viscosity increasing additive and/or proppant additional additives may be added to the liquefied industrial gas as required.
