Rong Cao, Ph.D.

Research Scientist

Food Bioactives Chemistry and Biochemistry

Current research and/or projects

Dr. Cao leads multi-disciplinary teams to conduct national and international research to support AAFC’s mandate and priorities. His research focuses on two AAFC Strategic Objectives: “Improve attributes for food and non-food uses” and “Addressing threats to the agriculture and agri-food value chain”, in the Focus Areas of (1) Cereals & Pulses; (2) Agri-Food, (3) Bioproducts, and (4) Horticulture as set in AAFC’s Agri-Food Sector - Science Strategy. Dr. Cao is an internationally highly recognized authority in food bioactives and attributes, especially in those with antioxidant and anti-inflammatory effects. He contributes by developing novel methods for the identification of food bioactives and their important functional properties in all aforementioned four areas, by taking new approaches to assess bioaccessibility, bioavailability, metabolomics and molecular mechanisms of action, and by providing information essential to crop breeding and processing programs, health claims substantiation and to forage crops. Dr. Cao also addresses the above threats by developing new methods for the detection and identification of regulated and emerging mycotoxins, by using natural antimicrobials, and optimizing food processing conditions to mitigate mycotoxin contamination.
