Corn Gluten

Source: Non-GMO yellow corn, wet milling by-product
Appearance: Fine free-flowing yellow powder
Crude protein: 60% - 70% typical
Key amino acids: Methionine and leucine

Corn Gluten Meal is extracted from high-quality non-GMO yellow corn during wet milling, as a by-product of starch or syrup production, then dried and milled into a fine free-flowing yellow powder. It typically carries 60-70% crude protein, rich in methionine, leucine and zeaxanthin, with good digestibility and bioavailability. The xanthophyll content gives it a second job as a natural pigment, which is why poultry and pet food formulators value it beyond the protein alone.

Why buyers specify this grade

60-70% crude protein with good digestibility and bioavailability
Rich in methionine and leucine, amino acids that are limiting in many rations
Natural pigmentation from xanthophylls, useful for yolk and skin colour
Binding capacity and improved feed palatability in the formulation
Non-GMO, free from antibiotics and hormones

Nitrogen source in fermentation media and industrial fermentation

Who buys it

Poultry and aquafeed formulators
Pet food manufacturers
Swine and cattle nutritionists
Fermentation plants needing a nitrogen source

Problems it solves

Methionine shortfall in a ration that would otherwise need synthetic supplementation
Pale yolk and skin colour where a natural pigment source is preferred to a synthetic one
Poor binding in pelleted feed
Non-GMO sourcing requirements from an export customer

Packing and options

Packing format confirmed at quotation

How it compares

Soy protein carries a more balanced amino acid profile for monogastrics, and pea protein suits allergen-sensitive formulations. Corn gluten meal is the one to choose for protein density with natural pigmentation, and where methionine rather than lysine is the limiting amino acid in the ration.

Handling and storage

Balance the ration for lysine, which corn protein is not rich in, when raising the corn gluten inclusion
Use the pigmentation contribution deliberately in poultry and pet food formulation
Store dry and sealed, keeping the powder free flowing
