نگهداری مواد غذایی توسط اشعه
This presentation provides a comprehensive overview of food irradiation, a preservation technique using ionizing radiation such as gamma rays, x-rays, or electron beams. It explains the process, which destroys pathogens, inhibits sprouting, and controls pests without heat. Key benefits include improved food safety, reduced waste, extended shelf life, and nutrient preservation. The deck covers global usage in over 60 countries, varying regulations, endorsements from FDA, WHO, and others confirming safety, as well as challenges like consumer perceptions and facility needs. Concludes with key采取s
