Cereals, carbohydrates, and vitamin C. Improving the nutritional value
of cereal-based foods and feeds; chemical and biological properties of
vitamin C; properties and uses of starch.
Professor of Grain Science and Industry;
B.S. 1958, Ph.D. 1965, Purdue University.
My laboratory is involved in identification and synthesis of new forms
of vitamin C. Esters and ethers of L-ascrobic acid are often more stable
to O2; they are being tested in pharmaceuticals, foods, and feeds for cultured
marine animals. This laboratory is also interested in cereal carbohydrates
that affect food processing, nutritional values, and new or improved industrial
uses. Wheat and grain sorghum are major sources of carbohydrates in the
Great Plains.
