Abbreviated Bio

Dr. Schoenfuss started at the University of Minnesota in 2008 as an assistant professor after working as a food product developer for General Mills in Golden Valley, Minnesota since 1997. Her extensive experience in food product formulation and commercialization brings a unique perspective to her teaching and research in the Department of Food Science and Nutrition. Dr. Schoenfuss received a B.S. in Dairy Science from Cal Poly, San Luis Obispo in the Dairy Product Technology concentration. While she was an undergraduate, she studied Food Technology at Massey University in Palmerston North, New Zealand for one year. She received her M.S. in Food Science from Virginia Tech, and Ph.D. from Louisiana State University in the Department of Dairy Science.

Research

Research areas include how the formula and manufacturing process affects natural and process cheeses, fermented milks, and other dairy ingredients. We use analytical tools to measure chemical and physical properties, and sensory methods to evaluate quality differences.
