Dr. Barrett’s research program addressed 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 included polyphenol oxidase, lipoxygenase, pectin methylesterase, polygalacturonase, peroxidase and hydroperoxide lyase. Handling and processing technologies of interest included fresh-cut processing, canning, freezing, irradiation, high pressure and aseptic processing. She also directed the Center for Advanced Processing & Packaging.
