Question

Quizplus · Accepted Answer

Gamma irradiation can be used to either sterilize or pasteurize food, depending on the dose of radiation. It does not leave any radioactive particles in the treated substance and it kills by damaging the DNA of microorganisms, making them unable to multiply. Although the process generates some heat, it does not denature proteins. Gamma irradiation has been approved for use on certain foods by several international organizations, including the World Health Organization and the United States Food and Drug Administration.
