Process history of calcium caseinate affects fibre formation

Abstract In this study, we compared the physical properties and structuring potential of spray-dried calcium caseinate (Scaca) and roller-dried calcium caseinate (Rcaca). Scaca formed more pronounced fibrous materials upon shearing compared with Rcaca. The rheological measurements revealed that the Scaca dispersion exhibited more solid-like behaviour. Besides, the particle size in excess water was larger for Rcaca (2–300 μm), while Scaca mainly contained small caseinate aggregates (
