Our insistence on coupling exceptional products and unparalleled service has gained GPC recognition around the world.  Our reputation has grown in places far removed from our headquarters, research and development, and main production facility in Muscatine, Iowa.  A second production facility is located in Washington, Indiana.


Founded in 1943, GPC is a privately owned company with a solid history and the vision for continued success in the future.  Our chosen mission is to manufacture, distribute, and market customer-specified food, pharmaceutical, and industrial grade products of uncompromising quality.  GPC's substantial investment in the finest people, facilities, technology, and customer support services reflects the seriousness of that commitment to quality.  

The cornerstone of our growth is hard work—we work with our customers as well as for our customers to satisfy their individual needs.  Our growth comes from expanding established markets, introducing new products, as well as improving our existing product line.  We also create new marketing opportunities through the knowledge gained from research and practical experience.

GPC has a broadly diversified line of products, mainly derived from nature's abundance:  corn.  These products include maltodextrins, corn syrup solids, and starches for the food, pharmaceutical, and personal care markets; ethyl alcohol for beverage and industrial use; starches for the paper, corrugated box, textile, and wallboard industries; corn oil; and animal feed ingredients.

GPC customers worldwide have discovered the advantages of using our various products to improve process efficiency, functionality, and end product quality.  That customer satisfaction is why GPC continues to be a leader in the industry.
