What is a irradiation process?
Food irradiation is a processing and preservation technique with similar results to freezing or pasteurisation. During this procedure, the food is exposed to doses of ionising energy, or radiation. At low doses, irradiation extends a product’s shelf life.
What is irradiation and examples?
Irradiation Definition Irradiation refers to the exposure of a substance to radiation from a variety different sources. Some examples of ionizing radiation include electronics, visible and infrared light, microwaves, and electromagnetic waves (e.g., radio waves, power, and electronic receivers).
What is the irradiation effect?
“Irradiation is a technology that leaves no residue in food products and destroys the DNA of microorganisms to prevent them from multiplying. When you irradiate food, you produce an effect on microorganisms due to their effects on DNA and cell membranes.
What is the principle of irradiation?
In food irradiation, ionizing radiation uses electricity, x-rays and gamma rays to destroy microorganisms, such as bacteria, viruses or insects in food. Irradiation also delays ripening, improves rehydration, increases juice yield and inhibits sprouting, which helps preserve foods and/or keeps them at their peak.
Which is the best definition of the term irradiation?
Definition of irradiation 1 : exposure to radiation (such as X-rays or alpha particles) 2 : the application of radiation (such as X-rays or gamma rays) for therapeutic purposes or for sterilization (as of food) also : partial or complete sterilization by irradiation 3 : irradiance
What happens to food when it is irradiated?
Irradiation does not make the food itself radioactive, although chemical changes can occur in the food when chemical bonds break due to irradiation. However, research into these chemicals has not revealed any harmful effects [1] . To irradiate food, electron beams, X-rays or gamma rays are used.
What is the dictionary definition of the fray?

What is the definition of external beam irradiation?
