A device developed in Scotland uses ozone to make food safer for consumers and extend the shelf-life of food products by one day.
Dr Declan Diver and Dr Hugh Potts of Glasgow University’s School of Physics and Astronomy have prototyped a system to rapidly, safely and temporarily turn some of the oxygen inside the sealed packaging into ozone, which acts as a germicide.
Plasma generated by a retractable device held briefly against the surface of plastic or glass packaging splits the bonds between oxygen molecules inside the packaging which then reform as ozone.
