citric acid
Citric acid is a mild preservative that helps antioxidants keep fat fresh. What it does in pet food, and how Bowlmark treats it.
Also appears on labels as: citric acid (a preservative) · citric acid (preservative) · e330
What it is
Citric acid is an organic acid used as a preservative and pH adjuster, listed as citric acid or E330. In pet food it is almost always produced by fermentation rather than squeezed from citrus, and it appears in tiny functional amounts.
Why it's in pet food
It works as a synergist: on its own it is a modest preservative, but alongside antioxidants such as mixed tocopherols it noticeably extends how long fat stays fresh. It also fine-tunes acidity in wet and semi-moist formulas.
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.
Citric acid carries no deduction — the engine treats it as a neutral processing aid. The additive pillar's natural-preservation bonus is deliberately narrow: it applies only when mixed tocopherols or rosemary extract appear on the label, so citric acid alone neither earns points nor loses them.
