Drinking yoghurt is firm, creamy or liquid acidified milk
products manufactured from pasteurized milk by use of thermophilic lactic acid
bacteria.
In order to increase the dry matter content of the yoghurt
in line with the given local preferences (which vary around the world), the
milk can be concentrated or powder can be added to obtain a fortification - or
the milk can be concentrated by means of ultrafiltration (UF). Typical standard
yoghurt is not heat treated subsequent to fermentation and does not contain
binding agents.
The various types of yoghurt are characterized by their
structural properties. In drinking yoghurt the gel has been broken in the
fermentation tank, homogenised and cooled before packaging. A lower dry matter
content and homogenization after fermentation result in drinkable yoghurt with
low viscosity. Normally stabilizer is added to ensure stable yoghurt without
sedimentation.
