Lactic Acid in Pet Food

Grade B-1 ptsPreservatives

What It Is

"An acid produced by bacterial fermentation, used to adjust pH and inhibit spoilage."

Health Impact

A mild, well-tolerated acidifier — the same compound produced naturally during fermentation of foods like yogurt. Functions as a gentle preservative by lowering pH enough to slow bacterial growth. One of the more benign synthetic-sounding additives on a label. Score: 6/10.

Why This Grade

A minor caveat applies — usually a processing step (e.g. rendering into a meal), a moderate allergen history, or a named-but-fattier source — but nothing on our risk watchlist. -1 pt deducted.
