Abstract:
A method for reducing the buffering capacity of milk raw material, wherein said method comprises(a) solubilizing carbon dioxide under pressure into a milk raw material, which has a protein concentration of between 25 and 150 g/l, in an amount sufficient to reduce the pH of the material to within the range of 5 to 6.5; (b) subjecting the product of step (a) to diafiltration under carbon dioxide pressure and conditions sufficient to reduce the calcium quantity per gram of protein to between 30% and 80% of its starting ratio; (c) increasing the pH of the diafiltration retentate by removal of a sufficient amount of the solubilized carbon dioxide as necessary to obtain a pH that falls within the normal pH range for non-carbonated milk products which have the same protein content as the retentate.
