Diane M. Barrett
Ph. D. Cornell University, 1989
M.S. Food Chemistry, University of Wisconsin, Madison, 1980
Dr. Barrett’s research program addresses the effects of raw material quality and processing on color, flavor, texture and nutritional quality of fruit and vegetable products, with particular emphasis on enzyme-catalyzed reactions which result in qualitative losses. Specific enzymes studied include polyphenol oxidase, lipoxygenase, pectin methylesterase, polygalacturonase, peroxidase and hydroperoxide lyase. Handling and processing technologies of interest include fresh-cut processing, canning, freezing, irradiation, high pressure and aseptic processing. She also directs the Center for Advanced Processing & Packaging.
