Raw Material Sodium Tripolyphosphate Phosphate For Biscuits

1.Description

Renze Sodium Tripolyphosphate is a high-purity phosphate additive specifically engineered for biscuit production. With ≥94% active content and optimized granulation, it delivers superior dough conditioning, texture enhancement, and shelf-life extension for premium baked goods.


Key Benefits:
✔ Dough Strengthening – Improves machinability by 30-40%
✔ Moisture Retention – Reduces staling for longer freshness
✔ Texture Optimization – Creates uniform, crisp texture
✔ pH Control – Maintains ideal alkaline conditions (pH 7.5-8.5)

STPP Sodium Tripolyphosphate Phosphate Preservative Raw Material For Biscuits

❓ "How to compensate for gluten absence with STPP?"
→ Formula adjustment:
• 0.3-0.5% STPP in rice-based formulations
• Combine with 0.1% xanthan gum
• Adjust water absorption +5-8%


❓ "Does STPP affect flavor in savory biscuits?"
→ Sensory analysis shows:
• ≤0.3%: No detectable flavor impact
• 0.3-0.5%: Slight mineral notes (masked by seasoning)
• >0.5%: Requires flavor adjustment

❓ "How does STPP improve wafer crispness?"
→ Mechanism of action:
Starch modification - reduces retrogradation
Protein interaction - strengthens matrix
pH adjustment - optimizes browning
Result: 20% crisper texture (acoustic measurement)
