Food Grade Sodium Acid Pyrophosphate - Premium Quality for Food and Beverage Industry
Sodium Acid Pyrophosphate (Na₂H₂P₂O₇), a high-purity, anhydrous phosphate compound, is a versatile food additive renowned for its leavening, buffering, and chelation properties. With ≥95% purity (food-grade compliance per FCC/USP standards), this white crystalline powder enables precise control over dough rise, pH stability, and texture enhancement in baked goods, processed meats, and beverages. Its slow-reaction kinetics and thermal stability make SAPP indispensable for manufacturers prioritizing consistent product quality, extended shelf life, and compliance with global food safety regulations.
Functional Benefits
1. Leavening & Texture Optimization
- Controlled gas release: Reacts with baking soda (NaHCO₃) at 40–60°C to ensure delayed CO₂ release (ideal for refrigerated/frozen dough)
- Crumb structure: Reduces gluten toughness by 20% in cakes/muffins (usage: 0.5–1.5% flour basis)
- Oil absorption control: Lowers fat uptake by 15% in fried batters via starch modification
2. pH & Ion Management
- Buffering capacity: Maintains pH 3.5–5.5 in processed cheeses to prevent protein coagulation
- Calcium chelation: Binds 1.2 mmol Ca²⁺/g in potato products, inhibiting after-cooking darkening
- Metal scavenging: Reduces iron-catalyzed oxidation in canned seafood by 40%
3. Preservation & Process Efficiency
- Synergistic antimicrobial: Enhances sorbic acid efficacy by 30% in meat emulsions (0.1–0.3% SAPP)
- Emulsion stabilization: Improves water-binding in poultry brines (2–4% solution achieves 8–12% weight gain)
- Freeze-thaw tolerance: Reduces syneresis in frozen dough by 25% through starch cross-linking
4. Specialty Applications
- Plant-based analogs: Mimics egg functionality in vegan baked goods (0.2–0.4% substitution)
- Instant beverage powders: Prevents caking via surface acidification (0.05–0.1% dosage)
- Seafood processing: Inhibits struvite formation in canned tuna (0.05–0.15% w/w)
Technical Specifications

- Appearance: White free-flowing crystalline powder (150–300 μm particle size)
- Solubility: 15g/100mL in water (25°C); pH 3.5–4.5 (1% solution)
- Pyrophosphate content: 63–67% (as P₂O₅)
- Heavy metals: Pb <1 ppm, As <0.5 ppm (ICP-OES)
- Fluoride: ≤10 ppm (ion-selective electrode)
- Microbial safety: TPC <1,000 CFU/g; absent pathogens per 25g
Advanced Food Applications
1. Bakery & Snack Systems
- Refrigerated dough: 1–1.8% ensures 60-day leavening stability at 4°C
- Tortilla chips: 0.3–0.6% modifies gelatinization for crisp texture
- Gluten-free bread: 0.8–1.2% compensates for lack of natural leavening
2. Meat & Poultry Processing
- Emulsified sausages: 0.2–0.4% increases protein extraction by 25%
- Cured meats: 0.1–0.2% maintains redox stability of nitrite
- Restructured products: 1–2% enhances binding in low-salt formulations
3. Dairy & Alternatives
- Processed cheese: 0.5–0.8% prevents oil separation during melting
- Plant-based yogurt: 0.05–0.1% stabilizes pea protein at pH 4.2–4.6
4. Convenience & Prepared Foods
- Instant noodles: 0.1–0.3% reduces breakage during frying/dehydration
- Canned soups: 0.05–0.15% inhibits pectin depolymerization
- Batter coatings: 0.4–0.6% improves adhesion to chicken/fish substrates
5. Beverage Innovations
- Acidified drinks: 0.01–0.03% buffers citric acid without metallic aftertaste
- Plant milks: 0.02–0.05% prevents calcium sedimentation in almond/oat bases
- Powder mixes: 0.1–0.2% enhances dispersibility of cocoa particles
Quality Assurance
- Manufactured under FSSC 22000 & ISO 9001 frameworks
- HACCP-monitored calcination process (450–600°C)
- 36-month shelf life in moisture-resistant polyethylene liners
- Allergen-free production (BRCGS Grade AA facility)
- Blockchain-enabled traceability from phosphate rock sourcing
Sustainable Production

- Carbon footprint: 0.45 kg CO₂eq/kg (30% lower vs. conventional methods)
- Water stewardship: 95% process water recycled via reverse osmosis
- Byproduct valorization: Residual sodium compounds converted to detergents
Operational Guidelines
Optimal Formulation Practices
- Baking systems: Use 25–30% SAPP with 70–75% baking soda for pH-neutral rise
- Meat brines: Pre-dissolve in 4°C water to prevent premature protein interaction
- Beverages: Add post-pasteurization to avoid reaction with calcium ions
Synergistic Combinations
- With MCP: 1:1 ratio of SAPP:Monocalcium Phosphate for dual-stage leavening
- Sodium erythorbate: 0.01% SAPP + 0.005% erythorbate extends cured meat color by 40%
- Xanthan gum: 0.1% SAPP + 0.05% xanthan enhances freeze-thaw stability in gluten-free products
Regulatory Compliance
- FDA 21 CFR 182.1087 (GRAS)
- EU Regulation (EC) No 1333/2008 (E450(i))
- CODEX STAN 192-1995 (INS 450(i))
- Halal (JAKIM) & Kosher (OU) certified
