Also known as: Sodium caseinate, Calcium caseinate, Milk protein, Casein protein
| Source | Halal Ruling |
|---|---|
| Acid Casein | Generally halal — produced by acid precipitation, no rennet involved |
| Rennet Casein | Varies — depends on rennet source (halal if microbial rennet used) |
Casein is the main protein in milk and can be extracted through acid precipitation (acid casein) or rennet coagulation (rennet casein). Acid casein does not involve animal enzymes and is generally halal. Rennet casein depends on the rennet source. Sodium caseinate and calcium caseinate are salts of casein used as food additives.
Listed as 'casein', 'sodium caseinate', 'calcium caseinate', or 'milk protein'. Hard to determine if acid or rennet casein from the label alone.
