Grain Processing Corporation (GPC)

Grain Processing Corporation (GPC) is a family-owned company, founded and headquartered in Muscatine, Iowa. Being a family-owned company allows us the freedom to focus on what counts — you — our customers. We work hard to satisfy our customers and bring them value. At GPC, we have a deep history of innovation and a strong dedication to quality. Our ongoing investment in the finest people, facilities, technology and customer support services reflects the importance of our commitment to quality. Corn is the mainstay of most of our diversified product line. And we use the entire kernel to produce our ingredients, so as not to squander any of this valuable resource. A wet-milling process efficiently separates the corn into its various components: starch, protein, fiber and germ. The starch fraction is used to produce our primary products, which are supplied to various industries, including food, beverage, pharmaceutical, nutraceutical and personal care.
