Distiller Proteins

We produce a wide selection of essential ingredients for animal, fish, pet and human food markets. We are continually working to increase the value of the products of our mills and distilleries.

Corn Gluten Meal

Corn gluten meal is used primarily as a protein source in poultry, livestock rations, fish and pet foods because it supplies vitamins, minerals and energy. Pet food processors value it for its high digestibility and low residue, and it is also a good source of xanthophylls for use in broiler and layer rations.

Corn Germ

At the Pekin Wet Mill, Alto Ingredients separates the germ of the corn kernel and sells it as an essential ingredient for corn oil for human food and corn germ meal for animal feed.

Distillers Corn Oil

Extracted from the thin stillage in the dry corn milling process, distillers corn oil provides a valuable source of energy that can be utilized in ruminant and monogastric diets. Distillers corn oil is also used as a feed stock for biodiesel production.

Corn Gluten Feed

Corn Gluten feed is a product containing primarily fiber, a moderate level of protein, and associated starch and steep water. It is used in poultry and livestock rations.

Corn Condensed Distillers Solubles (CCDS)

A palatable, free-flowing, energy and protein source for cattle, corn condensed distillers solubles is a produced from the fermentation of corn starch during the corn wet milling process. Its high-energy content, natural protein and palatability, allows CCDS to serve a range or feed rations.

Distillers Grains

Distiller Grain is a valuable product from dry mills used primarily in dairy and feed lot rations. DGS is a medium-protein and high-energy ingredient consisting of a grain fraction and whole stillage from the yeast fermentation of grain.


Yeast is extracted from a the starch stream in the wet mill, processed, dried, bagged and sold for animal, pet and human food applications and is AIB food grade and also Kosher certified. Learn more about our Yeast operation


Our distilleries produce CO2 from fermentation and is sold at the Pekin Campus and at two of the Western distilleries for processing into liquid CO2 and dry ice for beverage and industrial uses.
