Research

Research interests are the chemistry and analysis of cereal grains and other foods, including evaluation of the effects of processing technologies on the composition and chemistry of foods. Also, the development of rapid analytical methods for measuring food quality, and for predicting the end use characteristics of grains and other commodities. Current projects include development of near-infrared spectroscopy procedures to detect internal insect infestation in stored wheat, to evaluate frying oil quality, to measure degree of processing of extrusion cooked cereal products, and the development of chromatographic methods for measuring vitamins in cereal products.
