Answer:
Explanation:
WHEN OILY OR FATTY FOODS ARE KEPT IN OPEN FOR LONG, THEY REACT WITH OXYGEN IN AIR. THIS RESULTS IN THE OXIDATION OF THE OILS AND FATS IN FOOD AND THEY BECOME UNFIT FOR CONSUMPTION.
THIS IS CALLED RANCIDITY.
IT CAN BE PREVENTED BY
1. STORING FOOD IN REFRIGERATORS.
2. FLUSHING PACKETS OF FOOD WITH NITROGEN GAS, ETC.
