Summary

Buffalo milk collected within 4 h of milking was standardized (4·5% fat and 8·5% SNF) and processed in an ultra high temperature plant at 5 °C intervals. Changes in viscosity, free tyrosine and sedimentation were measured over 6 months at 15 and 30 °C. We suggest that an interaction probably occurred in the casein and whey proteins (β-lactoglobulin) and caused changes in the physical and chemical qualities of these milks during storage. Variations in the casein particle sizes were observed in the milks during storage by electron microscopy.
