Cottage cheese whey was concentrated to 26.2% total solids by ultraosm
osis. Yoghurt mixes were prepared with skim milk powder (SMP) and with
part of the SMP replaced with whey concentrate. Chemical, physical an
d sensory properties were assessed. Up to 20% of the milk solids non-f
at in a yoghurt formulation with SMP could be replaced with the whey c
oncentrate to obtain a satisfactory yoghurt.
