Technical Support for the laboratories of Dr. G.K. Harris and Dr. J.C. Allen where our current research interests include investigation of various food materials for vitamins, phenolics, and other bioactive components. Among other foods, we study North Carolina based products, such as the locally grown muscadines and sweet potatoes. Our research encompasses a variety of nutritionally important factors in our fresh and processed foods.
