Dairy Foods Manufacturing Researchers

The Dairy Manufacturing Impact Group (DMIG) serves as a focal point for research and outreach activities related to the quality, functionality and safety of dairy products and dairy ingredients.

Research activities undertaken under the auspices of the DMIG includes projects that can be classified as microbiology, chemistry, physical characterization, processing and product utilization. Both applied and basic research is conducted within the context of the group. Outreach activates of the DMIG include the Cultured Dairy Products Short Course, The Pasteurizer Operators Workshop, and the Ice Cream Short Course. In addition, the group serves as a forum for discussion of dairy manufacturing related extension issues.
