Question

why is it advised to keep the curd in refrigerator especially during summer?

Answer 1

Curd is produced by the coagulation of milk. Generally, coagulation of milk occurs due to the lactic acid produced by curd forming bacteria (Lactobacillus).After the formation of curd, it is advised to keep it in refrigerator to stop the growth of these acid forming bacteria as over production of lactic acid results in souring of curd and spoils it making it inedible. Also, these bacteria grow at a faster rates at room temperature during summers, so, it is advisable to store it in refrigerator in summers as it will get spoiled in less time during summers.
