Research

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.
