WebJul 22, 2024 · What is food irradiation? When food is irradiated, it's exposed to ionising radiation, either from gamma rays, a high-energy electron beam or x-rays. These rays are similar to microwaves. They pass through the food just like in a microwave, but don't heat it up to any significant extent. WebThis work demonstrates that it is possible to extend the shelf-life of fresh fruits and vegetables at room as well as at refrigeration temperatures by gamma radiation, by surface pasteurization, sprout inhibition, and also by retarding the ripening processes. embryo stem cell ethical https://more-cycles.com
