What Grain Processing Corporation does

Grain Processing Corporation (GPC) is a specialty ingredient manufacturer founded on February 11, 1943, and headquartered in Muscatine, Iowa. The company operates corn wet-milling facilities in Muscatine and Washington, Indiana, alongside a specialty flour milling operation in Grinnell, Iowa acquired in 2022. GPC produces and sells functional and nutritional ingredients across eight identified industry verticals — food and beverage, alcohol, nutraceutical, personal care, industrial starch, specialty milling, co-products, and international — exporting to more than 70 countries through regional sales offices in Europe, Asia, and Latin America. The company is privately held, fourth-generation family-owned, and a subsidiary of KENT WORLDWIDE.

GPC's product portfolio spans maltodextrins and corn syrup solids (MALTRIN, MALTRIN QD, MALTRIN SS), resistant starch (FYBRIN RS, delivering a minimum of 85% dietary fiber on a dry basis), modified food starches (PURE-DENT, PURE-COTE, PURE-GEL, INSCOSITY), pulse-based flours and protein concentrates (PURE-PULSE chickpea, faba, lentil, and soy; PURE-TEIN faba protein concentrate), high-purity ethyl alcohol produced from 100% corn at less than 1ppm total impurities versus a 512ppm USP specification, industrial starches (SUPERBOND, CHARGEMASTER, COATMASTER, SEALMASTER), and corn co-products (corn protein meal, corn protein feed, crude corn oil, corn germ). Underlying technology centers on proprietary wet-milling that separates the corn kernel into starch, protein, fiber, and germ fractions, proprietary steaming and milling for pulse ingredients, and an in-house Technology Development Center in Muscatine. Certifications include BRCGS, Kosher, Halal, Non-GMO Project Verified, and Sedex membership.

GPC operates as a B2B ingredient supplier, generating four primary revenue streams: specialty ingredient sales (food, beverage, nutraceutical, personal care), ethyl alcohol (beverage, pharmaceutical, personal care, industrial), industrial starch products (paper, corrugating, textiles, mining), and corn co-products (animal and pet nutrition). Pricing is quote-based with multi-year supply contracts negotiated through an enterprise field sales force and inside sales team that includes technical application specialists and a Solutions Center for product evaluation and formulation collaboration.
