Question
Which one of the following methods is used to separate cream from milk?
Answer: Option C
:
C
Centrifugation is used to separate cream from milk. Centrifugation works on the principle of density difference. When amixture is spun rapidly, thedenser particles are forced to the bottom and the lighter particles stay on top.
Similarly, when milk is spun rapidly, the less dense fat globules which make cream rise to the top. These can be removed or 'skimmed' off the milk to make low fat milk called skimmed milk.
