Chang Yong (Cy) Lee has been working on biochemical aspects of plant foods. He has been teaching food chemistry-related undergraduate and graduate courses. His recent research focuses on nutraceutical roles of fruits, vegetables, cereals and herbal beverages that relate to antioxidant activity and bioavailability of bioactive phenolic compounds. The ultimate goal is to promote increased consumption of healthy plant foods in our daily diet.
Lee’s research interests have been the application of fundamental principles of chemistry and biochemistry toward the advancement of our understanding of chemical reactions that take place in plant foods during post-harvest and processing. Enzymes associated with sensory and nutritional quality of fresh and processed plant foods, including browning reactions were his main subjects of the research. In recent years, he focuses on various bioactive phytochemicals in relation to their chemical natures and bioavailability and which are associated with antioxidant, anticancer, and anti-neurodegenerative activities of the major flavonoids in fruits and vegetables, along with green teas, cocoa and coffee.
Lee’s teaching philosophy is to motivate students in active learning processes, rather than passive learning. He has been teaching Food Chemistry (FDSC 4180), Food Chemistry Laboratory (FDSC 4190) Capstone Project in Food Science (FDSC 4000), Readings in Current Food Chemistry (FDSC 6950).
