Trisodium Pyrophosphate (TSAPP)
Trisodium monohydrogen pyrophosphate is mainly used as a moisture-retaining agent or acidity adjuster in the food industry, and as a specialty pyrophosphate in pet food formulations alongside STPP and TSPP.
- Manufacturer since 1952 — batch-level Certificate of Analysis (COA) on every shipment
- Long-term supply contracts with committed monthly allocations, insulated from spot-market swings
- Third-party pre-shipment inspection (SGS / BV) welcomed on request
