Microwave technology shows decontamination promise
Research at Texas Tech University in the USA to develop microwave decontamination of food and water is reported to have reached the stage where commercial applications are a real possibility.
The University has formed a technology company, MicroZap, to exploit the work of the food microbiologists, engineers and other scientists involved in the research and develop practical applications.
The technology was originally developed in Italy and uses microwaves to raise the surface temperature of food products sufficiently to kill pathogens and spoilage organisms without causing sensory changes to the product.
Research at Texas Tech has shown that it can be used successfully to decontaminate a range of foods, including meat products and fresh produce. Treatment of bread is said to have achieved a shelf life of 60 days. MicroZap says that the technology could also be used to produce safe drinking water in developing countries.
