Describe any 3 advances in food processing technology or packaging that can reduce the risk of foodborne illness
Foods can be irradiated with high-energy beams of cobalt 60 that will kill microbes within the foods by destroying bacterial DNA. Irradiation also preserves foods.
Modified atmosphere packaging (MAP) ensures that microbes or toxins from the air cannot get into a food. Some disease-causing bacterial species grow well in the absence of oxygen within MAP, so it is very important to store perishable foods in MAP in the refrigerator or freezer.
Some food wraps also contain antimicrobial substances that can prevent the growth of disease-causing pathogens on food as well.
