corn gluten meal

Grain

Corn gluten meal is concentrated corn protein — a plant way to raise the protein number. How Bowlmark scores corn on labels.

Also appears on labels as: maize gluten meal · corn gluten · maize gluten

What it is

Corn gluten meal is what remains of corn after the starch and germ are extracted — a dense plant protein running around 60% protein by weight. It is not related to wheat gluten; the shared word describes the protein fraction, not the plant.

Why it's in pet food

It raises the guaranteed-analysis protein number at plant-ingredient cost, and it supplies useful amino acids for the formula's total. The honest reading: protein from corn gluten meal is not the same story as protein from named meat, and the rest of the label tells you which story you are holding.

How Bowlmark scores it

Scores are deterministic math over the printed label — the rules below apply to every product identically, and nothing estimates or fills in a blank.

Two corn rules can touch it. The first-ingredient rule fires only on DRY formulas: the engine matches the word "corn" in the lead ingredient, so corn gluten meal leading a dry label takes the same deduction as plain corn — 10 points for dog food, 14 for cat food, on the ingredient-quality pillar. And it counts as a corn fraction for the splitting rule: three or more corn-word ingredients (corn, corn gluten meal, corn bran, …) inside the top eight is a single 12-point deduction.
