sorbic acid

Preservative

Sorbic acid is a mild mold and yeast inhibitor used in moist pet foods and treats. What it is, and how Bowlmark treats it.

Also appears on labels as: sorbic acid (a preservative) · e200

What it is

Sorbic acid is an organic acid that stops mold and yeast growth, listed as sorbic acid or E200. It was originally isolated from rowan berries; food-grade sorbic acid is synthesized, and potassium sorbate is its more soluble salt.

Why it's in pet food

Like the other mold inhibitors, it earns its place in higher-moisture formats — semi-moist foods, filled treats, dental chews — where mold is a real spoilage and safety risk.

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.

Sorbic acid carries no deduction on the additive pillar. The engine flags the synthetic antioxidant class with documented safety questions — BHA, BHT, and ethoxyquin — and treats mold inhibitors as neutral.
