Enfoque de solución

RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.

Typical Formulation Workflow
1
Process & Compliance Review
Map the application and contact points, and confirm food-grade and regulatory status (FCC/USP, Kosher/Halal, allergen) for every input.
2
Ingredient & Grade Selection
Select the right grade of acidulant, preservative, emulsifier, stabilizer, or processing aid for the formulation, label, and sensory targets.
3
Bench Trial & Dosing
Validate use level and performance in a bench or pilot batch, and specify packaging and lot traceability suited to food-safety requirements.
4
Quality & Shelf-Life Validation
Verify finished-product quality, microbial stability, and shelf life, and lock the spec with a CoA and document control for audits.

Potassium Citrate FG USP/FCC
CAS 6100-05-6
Quelación / Secuestro
CAS matches food-grade tripotassium citrate monohydrate. Citrate is a genuine pH buffer in the stated 3.5-6.5 band and a calcium sequestrant; potassium form is used as a low-sodium emulsifying/buffering salt in dairy (processed cheese, cream, evaporated/UHT milk) to stabilize casein and emulsions against buffer drift. Direct fit for this exact use-case.

Tetrasodium Pyrophosphate
CAS 7722-88-5
Ácidos y Sales
Quelación / Secuestro
CAS matches anhydrous TSPP. One of the classic phosphate emulsifying/melting salts for processed cheese and dairy: raises and buffers pH while chelating casein-bound calcium, preventing protein destabilization and fat separation. This is precisely the buffer-drift / protein-stability problem the page targets. Direct fit.
Punto de fusión:988 °C   Punto de ebullición:Decomposes   Densidad:2.45
