Dear kalitapadmanath@yahoo.in

Thanks for asking us a question in Ask the Expert section of TopperLearning.com.

In case of multiple questions within a query, please post each question individually and let us know where you are getting stuck so that we would be able to explain things better.

Answer to your 1st question:

Cow milk lasts for 5-7 days while packed milk lasts for 7-10 days if properly stored at required temperature. Cow milk will get spoiled early because it is not pasteurized.

 Answer to your 2nd question:

Colour change depends on various factors like temperature, humidity, sunlight, type of fruit. So the time for colour change vary because of above mentioned factors.
