Description of Research Interests

Food Chemistry: Lipid biotechnology/chemistry/biochemistry. We work on the chemical and enzymatic modification of lipids, including the production of structured lipids and various fat analogs. We then study chemical, physical and physiological properties of modified lipids and their food applications.  We design fat analogs for use in infant formula, trans-free margarines, trans-free spreads, trans-free shortenings, cosmetics, neutraceuticals, or as food ingredients.  We also isolate, characterize, and assess the antioxidant capacities of phytochemicals.
