What type of chemical changes occur while milk changed in to curd? Explain with phenomena of chemical process​

Answer 1

Answer:

Changing of milk into curd is a chemical change, because the sugar in milk gets converted to acid, which in turn changes milk from liquid form to solid form. Milk contains a sugar, lactose. This lactose turns to lactic acid due to the presence of bacteria in the milk (lactobacillus).
