Overview
High-protein loads typically require gums, maskers, and stabilizers to be palatable. FSPI disappears at high concentrations — no grittiness, no off-notes, no formula penalties. Finally ship a clean-label RTD with 20g+ protein per serving.
The Constraint
High-protein RTD formulations require gums, stabilizers, and flavor maskers to be palatable. Above 15 to 20g protein per serving, grittiness and off-notes become unavoidable. The workaround: longer ingredient lists, higher costs, compromised mouthfeel.
The Unlock
FSPI delivers 90 to 99% solubility at high concentrations with a neutral flavor profile. No grittiness. No beany taste. No maskers required. Push protein claims to 20g+ per serving with a cleaner label and smoother texture.
