How are gamma rays used in food irradiation?
How are gamma rays used in food irradiation?
During irradiation, gamma rays, x-rays, or high-energy electrons pass through the food, destroying or inactivating bacteria and viruses that cause foodborne illness.
What do gamma rays kill in food?
Food irradiation reduces or removes pathogens, such as bacteria and molds, that spoil food and cause food poisoning and other illness. For example, irradiation can kill Escherichia coli, Campylobacter and Salmonella bacteria.
Is gamma irradiated food safe?
Are irradiated foods safe? Yes, irradiated foods are safe. Irradiation makes meat and poultry safer by reducing the numbers of harmful bacteria and parasites. Food irradiation does not make foods radioactive.
What food is the most radioactive?

- Beer. pCi per kg: 390.
What are the dangers of food irradiation?
Radiation can do strange things to food, by creating substances called “unique radiolytic products.” These irradiation byproducts include a variety of mutagens – substances that can cause gene mutations, polyploidy (an abnormal condition in which cells contain more than two sets of chromosomes), chromosome aberrations …
What happens if you eat irradiated food?
FSA Explains. When food is irradiated, it absorbs energy. This absorbed energy kills the bacteria that can cause food poisoning in a similar way that heat energy kills bacteria when food is cooked. They can also delay fruit ripening and help stop vegetables from sprouting.
What does irradiated food mean?
Table of Contents. Definition. Irradiated foods are foods that have been exposed to a radiant energy source to kill harmful bacteria, insects, or parasites, or to delay spoilage, sprouting, or ripening.
How are gamma rays used in the food industry?
Food Industry Applications. Gamma rays, namely in the form of a radionuclide called cobalt 60, are used to preserve food in the same way as they are used to sterilize medical equipment in that they irradiate decay causing bacteria.
What does the irradiation of a food product mean?
What does the Irradiation of a Food Product mean? Irradiation of Food Food irradiation is a technology that uses radiation to control food spoilage by destroying food borne pathogens . Since the results are similar to pasteurisation it is also called “cold pasteurization.”
How does gamma irradiation sterilize?
Gamma irradiation is known as a ‘Cold Process’, which means it does not significantly increase the temperature of the processed product and is not reliant on humidity, temperature or pressure. This makes it ideal for sterilisation and decontamination of packaged goods. It works by breaking down bacterial DNA and inhibiting bacterial division.
