The present study showed clear differences in the measured rheological and physicochemical properties of yoghurt cultures prepared from conventionally heated and TS milk. Set type yoghurts manufactured from TS milk showed increased gel firmness and viscosity as well as markedly improved WHC compared to conventionally produced yoghurts. Hence, TS has the advantage of improving the homogenisation of milk in a single unit operation, and also the potential to facilitate the production of commercial set type yoghurt in which supplementation with milk solids can be substantially reduced.
