coagulation of milk at relatively higher temperature. The chemical and physical Changes in casein and whey proteins brought about by the combined action of heat and acid treatments‚ form the basis of paneer making. When milk is acidified‚ the Colloidal calcium phosphate in the case in micelles progressively solubilises and aggregation of the casein occurs as the isoelectric point is approached. In milk of Normal pH‚ the casein micelles are stabilized by hydration and steric repulsion due to their negative
