Food Preservation

Food preservation by radiation is a food processing technology using gamma rays to lengthen the shelf-life of food. Cobalt-60 is the most commonly used radioactive source. The process has the effect of killing worms, sterilization, suppressing sprouting and delaying ripening, which reduce the wastage in storage and transportation of food, as well as improve the hygiene. There is no residual poisonous material and the food after the irradiation process contains no radioactivity.
