4. Dairy protein ingredients: production process
Thanks to separative techniques and improved knowledge of the physico-chemical characteristics of milk proteins or their hydrolysates, numerous purification processes have been developed. They are based on the differential solubility of proteins as a function of pH, ionic strength and/or temperature, or on their specific size, charge or affinity.
4.1 Processes for obtaining dairy protein ingredients
Milk proteins and peptides are fractionated using various processes:
separation by bioconversion of proteins (precipitation);
steric molecular separation;
ionic molecular separation.
