soy flour
Soy flour is ground defatted soy — protein and binding in one term the engine watches twice. How Bowlmark scores it.
Also appears on labels as: soya flour · soybean flour
What it is
Soy flour is finely ground defatted soybean — a high-protein flour used for binding and protein contribution in kibble, semi-moist foods, and treats.
Why it's in pet food
It does wheat flour's structural job while raising the protein line — one ingredient, two functions, at commodity cost. Semi-moist foods lean on it particularly.
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 rules can touch soy flour. Leading a DRY formula it takes the corn/wheat/soy first-ingredient deduction (10 points dog, 14 cat, ingredient-quality pillar). And it counts as a soy fraction for the splitting rule: three or more soy-word ingredients (soy flour, soy protein concentrate, …) inside the top eight is a single 12-point deduction.
