beyond alcohol

To further increase the efficiencies of its integrated processes, the company added the initial stages of a corn wet milling operation in 1959. This included the steeping, milling, germ separating and oil expelling steps. After engineering and economic studies, the operations were expanded to produce high-quality, unmodified corn starch, commonly known as pearl starch. This system has been in operation since 1960 with several expansions since then. Along the way, the process was expanded to produce a range of acid-modified and oxidized starches. These industrial starches are marketed to the paper, corrugated box, textile, building products, mining and oil well drilling industries.

In the early 1960s, GPC began experimental production of its first sweeteners, but it wasn’t until 1969 that the company launched a line of hydrolyzed starch products: MALTRIN® maltodextrins + corn syrup solids. These products are used in a wide variety of applications in the food, nutraceutical and personal care industries, and the line continues to expand. GPC is the world’s largest, most dependable producer of maltodextrins. With an unmatched product line and the GPC commitment to quality, MALTRIN® products are the gold standard for the industry. In addition, GPC is a leading supplier of food, nutraceutical and personal care starches.

GPC’s broadly diversified line of products is mainly derived from corn and includes many products vitally necessary to the animal + pet nutrition industry, such as corn gluten meal, corn gluten feed, SOLULAC® distillers dried grains and a broad range of feed supplements.

MALTRIN® and SOLULAC® are registered trademarks of Grain Processing Corporation.
