Food and Bioproduct Sciences

The primary goal of our research program is to promote value-added utilization of carbohydrates in food, feed, and bioproducts. Specific research areas include:

1. Relationships between structure, functional properties, and enzymatic hydrolysis of starch
2. Chemical, physical, and enzymatic modifications of starch and other carbohydrates for novel industrial applications
3. Development of resistant starch, dietary fiber, and low-glycemic food and feed to improve the health of humans, pets, and animals
4. Use of novel processing methods to enhance functional attributes and nutritional quality of pulses and cereal grains
