Irradiation Method and Biopreservation
,“The irradiation process is another nonthermal technology that involves
exposure of food to ionizing or nonionizing energy and is known as cold
pasteurization”.
, IRRADIATION OF FOOD
It is the exposure to ionizing radiations
E.g. Beta particles and gamma rays
AKA, Cold pasteurization
Kills bacteria, molds , insects and pests
Reduces the ripening and spoiling of foods
Approx 500,000 tons of food is irradiated/year worldwide in 40 countries
Mainly spices and condiments, with an increasing segment of fresh fruits
are irradiated for fruit fly quarantine.
