Yoghurt: The Fermented Dairy Product

Yoghurt is a dairy product made by the fermentation of milk carried by the experience of bacteria. The bacteria used for the production of yoghurt are represented by the definition of yoghurt cultures. These bacteria ferment the milk sugar lactose into lactic acid which in turn acts on the milk protein to offer yoghurt its texture and characteristic flavor. Basically cow’s milk is used for making yoghurt all around the world but milk from water buffalo, goats, sheep, camels and yaks can be used for the exact same purpose in numerous parts of the world.

Dairy yoghurt is actually made by the culture of Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus salivarius subsp. thermophilus bacteria. Sometimes the species of Lactobacillus acidophilus, Lactobacillus bifidus and Lactobacillus casei will also be used for culturing. To make yoghurt first the milk is heated at 80°C to kill any undesirable bacteria if present and setting of milk proteins. The hot milk is then allowed to cool at 45°C. When the milk is completely cool then bacterial culture is added and the mixture is allowed to undergo fermentation for approximately 7-8 hours. The phrase yoghurt has been based on a Turkish word meaning to thicken or coagulate. Literature shows that the used of cultured milk products began about 2000 years ago. Süt Dolum Makinesi The early yoghurt was fermented spontaneously and kept in a goatskin bag that has been used for transportation.
