Sodium Tripolyphosphate
Food-Grade STPP– Phosphate Food Additive Used In Food Quality Improvers And Water Retention
- Overview
- Recommended Products
- Moisture Retainer: Bind with meat proteins to enhance water-holding capacity, preventing moisture loss during processing/freezing/heating. (e.g., frozen meat products).
- Tenderizer: Weaken muscle fiber structure, improving tenderness and chewability (e.g., ham, sausages, grilled meats).
- Emulsifying Stabilizer: Ensure even fat distribution, prevents separation, and enhances texture/sliceability (e.g., emulsified meats like sausages, luncheon meat).
