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.
