Notes:
: The addition of sodium dodecyl sulfate (SDS) during skim-milk reconstitution contributed to a modification of hydrophobic interactions and, consequently, to change in the micellar structure. SDS-induced modifications in casein micelles were investigated by biochemical measurements (soluble mineral and protein analyses, granulometric and electrokinetic potential measurements, and casein micelle solvation). SDS induced micellar κ-casein dissociation and caused a decrease in steric, hydration, and electrostatic repulsive forces between casein micelles and as a result altered micellar stability. Consequently, SDS-modified micelle aggregation occurred. Mineral analysis indicated that Ca, PO43- and Mg partitioning between aqueous phase and curd is similar, suggesting a possible bridging mechanism via minerals and SDS molecules.
