Food preservation can be achieved employing a spate of technological options and the very foundation of the food industry is based on innovations in the field. While conventional technologies like chemical preservation, thermal preservation and physical methods of preservation continue to be used for thousands of processed food products, newer ones like irradiation and other novel processes are getting increased attention from the industry. The necessity for carrying stabilized foods with extended shelf life into the space during exploration spawned the airocide technology which does not use any chemicals for obtaining practically complete kill of all microorganisms.
'While keeping perishables fresh is important to all food suppliers, the extra time in Food Banks creates a unique challenge. It is especially critical for Food Banks to ensure their donated food remains in the freshest, most nutritious state and has the longest shelf-life expansion as possible. The solution is AiroCide PPT. This NASA developed Air Sanitation technology will purify the air of airborne pathogens like mold, bacteria and even the swine flu virus without using ozone. It also eliminates VOC's like ethylene gas".
The very simplicity of this process makes itself attractive though the details are protected under IPO regime. How ever its relevance is limited to storage of foods under cold conditions where air circulation is a critical factor that will determine the efficiency of preservation. Installing airocide units in conjunction with cold rooms and air conditioning systems results in practically sterile air that will not contribute to spoilage through contaminated air.
