Ultrafiltration of skim milk at 1.3x protein concentration was used to
standardise cheese milk to a higher protein level in the manufacture
of a high quality Mozzarella cheese. Attempts to use other protein-enh
ancing technologies, low temperature evaporation and addition of skim
milk powder, were unsuccessful. Additional benefits of the ultrafiltra
tion technology were savings in starter and rennet in the order of 30%
per kilogram of cheese produced and an increase in yield up to 3%.
