Food Grade Sodium Tripolyphosphate (STPP-FG85)
ISO 22000 & Halal/Kosher Certified｜Meat & Seafood Processing Specialist｜Global Compliance Guaranteed
▶ Food Safety-Centric Formula
STPP-FG85 is a high-purity sodium tripolyphosphate (CAS 7758-29-4) manufactured under GMP+ food safety protocols, delivering 85% minimum active content (Na₅P₃O₁₀) with controlled heavy metal limits (<0.5ppm Pb/Cd). Certified by FDA 21 CFR 182.1810 and EU E452(i), it optimizes texture and shelf life while ensuring food contact safety.
