The content of viable lactic acid microflora and its evo-lution during cold storage resulted dependent on the type of yoghurt and the temperature of storage. Whole
yoghurts (Set and Drinking) showed to be,mainly at 12C,the types of yoghurt that strongly aected the viability of the lactic acid microflora.
