Question

butter milk and chilled milk what what will happen

Answer 1

Micro-organisms are present everywhere , they are very useful and help us in many ways.These micro-organisms which are useful  are called as useful micro-organisms.

The following are the observations we notice when we add buttermilk to chilled milk :

1.The milk will not change to curd because -  butter milk contains Lactobacillus bacterium (which converts milk to curd) which cannot multiply or grow in that cool temperature.(if it grows then only milk will change into curd)

2.Some situation its changes into curd but not completely(because of affect of external temperature)

If the same buttermilk add into the lukewarm milk then with in 5-6 hours you observe that milk changed to curd because of favorable temperature for growth

Answer 2

if we add butter milk and chilled milk nithing would happen to the milk because in chilled the temperature is very cool so in that the bacteria are inactive hence nothing would happen to the chilled milk
