Casein Protein 80%
Quick Summary
- Category: Proteins · Sourcing Origin: European countries · Form: Powder
- Slow-digesting dairy protein — ~80% protein by dry weight; distinct from Micellar Casein Isolate (Section 56) in processing method
- Typically sodium caseinate or calcium caseinate — chemically precipitated forms rather than the membrane-filtered micellar form
- Used in sustained-release protein formulations, high-protein foods, dairy applications
What Is Casein Protein 80%?
Casein Protein 80% contains approximately 80% protein by dry weight and provides the characteristic slow-digesting profile of casein dairy protein. It is distinct from Micellar Casein Isolate (Section 56): whereas micellar casein is produced by membrane filtration that preserves the native micelle structure, "Casein Protein 80%" in commercial contexts typically refers to sodium caseinate or calcium caseinate — forms produced by acid precipitation of casein from skim milk followed by neutralisation with sodium hydroxide (sodium caseinate) or calcium hydroxide (calcium caseinate).
The distinction matters for formulation: sodium caseinate is more soluble and dispersible in water than micellar casein, making it better suited to emulsified and liquid food applications; calcium caseinate has a slightly firmer, more gel-forming character. Both retain the slow-digesting physiological profile of casein — they gel under acidic stomach conditions and produce a sustained aminoacidemia — but the micellar structure is not fully preserved in the caseinate forms.
