Food irradiation

Description:
Untitled document

This is a processing technique that exposes food to electron beams, X-rays or gamma rays. The process produces a similar effect to pasteurisation, cooking or other forms of heat treatment, but with less effect on look and texture.

Irradiation can be used to kill bacteria that cause food poisoning, such as Salmonella, Campylobacter and E.coli.

It can also delay fruit ripening and help stop vegetables, such as potatoes and onions, from sprouting.

It is used in many parts of the world because it is an effective way of killing bacteria with some food, such as spices that are dried in the sun.
