agar-agar

Thickener

Agar is the seaweed gel with none of its cousin's controversy — carrageenan's shelf-mate, chemically distinct, quietly setting aspics since before pet food had labels.

Also appears on labels as: agar · e406

What it is

A gelling polysaccharide from red seaweeds (Gelidium, Gracilaria) — the classic vegetarian gelatin of kitchens and petri dishes. Though both come from red algae, agar and carrageenan are different molecules with different literatures: the contested gut-inflammation debate attaches to carrageenan specifically, not to agar.

Why it's in pet food

Firm, heat-stable gels in wet foods and toppers — jelly textures that hold at room temperature. Nutritionally it passes through as unfermented fiber, contributing texture and little else.

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.

Neutral: no deduction, no flag. The distinction from carrageenan is the page's one real job — the engine gives carrageenan an informational −8 on wet formulas because its literature is contested, and gives agar nothing because its literature is quiet. Same ocean, different molecules, different treatment: that's the roster working as designed.
