Making of Curd
Milk is turned into curd by bacteria.
Curd contains several micro-organism including Lactobacilli bacteria.
It promotes the formation of curd from milk.
When a little of pre-made curd is added to warm milk,then Lactobacilli bacteria present in curd multiply in milk and convert the lactose sugar into lactic acid.
This lactic acid then converts milk into curd.
Curd is added in making idlis and bhaturas to make them soft and spongy.
Bacteria are also involved in the making of cheese,pickles and many other food items.
