potato protein

Tuber & starch

Potato protein is the fraction that flatters the guaranteed analysis — real amino acids, plant-sourced, and a reason protein percent alone can't rank foods.

What it is

The protein concentrated from potato processing water: a legitimate, fairly digestible plant protein that shows up in grain-free and limited-ingredient recipes. Its job on many labels is arithmetic — lifting the crude-protein percentage without adding meat.

Why it's in pet food

Cost and numbers. Animal protein is expensive; potato protein raises the analysis panel for less. That isn't fraud — the amino acids are real — but a recipe leaning on potato and pea protein for its headline number is a different product than its front-of-bag photography suggests, and the ingredient list is where that shows.

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.

A potato-worded entry for the splitting base (≥3 in the top 8 → the single −12) and otherwise untouched: no flag, no bonus, no deduction alone. The engine's named-protein bonuses are reserved for named animal proteins leading the list — plant protein concentrates neither earn them nor get penalized; their tell is fraction-stacking, which splitting watches.
