Caseins and whey proteins of buffalo milk from two Indian buffalo breeds, Murrah and Surti, were investigated. Electrophoretical analyses and amino acid analysis showed that the breed difference between the two Indian buffalo caseins was very little. αs1-, αs2-, β-and κ-casein were isolated from Murrah buffalo milk by using Amberlite CG-50 and DEAE-Sephadex chromatography. Amino acid compositions of the caseins were in good agreement to those reported for Italian buffalo caseins. However, the relative proportion of the caseins was different from that reported for Italian buffalo casein. The lower proportion of αs2-casein in Indian buffalo casein compared to that in Italian buffalo casein was marked. Electrophoretical and immunological analyses showed that there was no difference in the major whey proteins between Murrah and Surti buffalo milks.
