Typically, dehydration and irradiation. The causes of most food spoilage is the growth of bacteria in the moist environment of the food. Irradiation can kill all the bacteria, so as long as the package is sealed, no bacteria can grow there. And dehydration removes most of the water from the food so that it takes up less space and weight, and stays edible for longer times.
