INTRODUCTIONFood industries are currently in the need of different innovative technologies tomeet the consumer demand.There are some of the technologies like HPP, pulsed electric field, highintensity pulses light etc.But attention is now focused on the ozone as a powerful sanitizer.Currently-more than 300 water treatment installation and more than 300potable water treatment plants are running all over the world.
WHAT IS OZONE?OZONE: highly reactive form of oxygen consisting of three oxygen atoms i.eO3.It is a colourless and extremely unstable gas.Ozone production takes place by the ventilation of electrical discharges of highvoltage in the air or pure oxygen.
Why Ozone?
The ruinous action of ozone on bacteria involves the significant damageto cell wall, cytoplasmic membrane and finally the DNA structure,resulting in sheer disability to resist an ozone attack.Ozone has proven to be 52% stronger than chlorine and effective over awider spectrum, it has been used around the world for drinking watertreatment, disinfecting and storage.
RECENT STUDIES ON OZONATION IN FOOD PROCESSINGIt was concluded that more than 90% reduction of total bacterial count wasobserved upon treatment of Chinese cabbages with ozonated water for around60 minutes.
