Warm milk turns acidic when curd is added. Milk
contains a sugar called lactose. Lactobacillus
bacteria present in the curd help in converting the
lactose sugar present in the milk to lactic acid by the
process of fermentation. This creates the acidic
medium needed for casein protein present in the
milk to coagulate to form curd.
