The Formula
Formulation
Stability
Whey protein is pH-sensitive, with denaturation possible around pH 4.5 and flocculation near pH 4-6. High temperatures (above 50-65°C) can cause coagulation, and refrigeration or preservatives are often needed due to bacterial growth risk.
Conflicts
- High temperatures (>50-65°C) can cause denaturation or coagulation
- Strong acids (e.g., high concentrations of AHAs) can lower pH too much, leading to denaturation of peptides
