Process Engineering Research & Development Center

The Process Engineering Research & Development Center–PERDC–has developed new processes for converting diverse agricultural crops and animal products into food, feed and industrial ingredients for more than 75 years. Formerly known as the Food Protein Center, the RELLIS-Campus venue is the only public fully equipped oilseed processing facility in the world, supporting both engineering research and training.

The center has its roots in the Texas A&M Department of Chemistry and Chemical Engineering, It began oilseed process equipment training in 1929 in collaboration with the Texas Cottonseed Crusher’s Association and the Oil Mill Superintendents Association and area-wide processing stakeholders. The research and development (R&D) program was later initiated as the Cottonseed Product Laboratory in 1939 to assist Texas farmers by developing new uses for local crops.

Stakeholders working with the center include governmental entities, trade groups, research associations and other universities, all benefitting from the center’s unique resources and training programs..
Mian Riaz, a Texas A&M professor in Nutrition and Food Science is the PERDC director.
