Anuradha Prakash, Ph.D., is Professor of Food Science at Chapman University in Orange, CA and Science Advisor to the FDA Pacific Regional Lab-Southwest. She is an Associate Editor for Radiation Physics and Chemistry. For the last nineteen years, her research program has focused on using irradiation to enhance the safety and shelf-life of fresh-cut fruits and vegetables and ready-to-eat meals. At present, she is evaluating the effect of irradiation on the quality of fruit treated by irradiation for insect disinfestation with the ultimate goal of eliminating global trade barriers by reducing the threat posed by invasive pests. The objectives of her USDA funded research are to:

  • Conduct dose response studies to determine tolerance of fruit to irradiation
  • Compare irradiation to conventional treatments
  • Determine the impact of commercial treatment and distribution conditions on the quality of irradiated fruit

She teaches Food Processing and Food Product Development.
