🟡 Sodium Tripolyphosphate in Pet Food

Grade C-2.5 ptsPreservatives

What It Is

"A phosphate salt used to retain moisture and help preserve texture, primarily in soft or semi-moist treats."

Health Impact

Functions mainly as a moisture-retention and texture agent rather than a true antimicrobial preservative. Phosphate additives have drawn scrutiny in human nutrition research for their potential contribution to excess phosphorus intake; pet-food-specific dosing hasn't been as well studied, but it's a synthetic additive worth noting rather than assuming is nutritionally inert. Score: 4/10.

Why This Grade

A real but unresolved concern: often an ongoing FDA/AAFCO research question (like the grain-free/DCM investigation), a common allergen, or a vague-but-not-alarming label claim. -2.5 pts deducted.
