Best Answer

When raw milk is allowed to stand for a day, the cream will rise to the top. This cream was skimmed off and the remaining milk was called skim milk.

This method is no longer used in most dairies and a mechanical separation of cream and milk is used.

Skim milk appears slightly blue because casein micelles (the casein content of milk which represents about 80 % of milk proteins) scatter the shorter wavelengths of visible light (blue) more than the red. The fat in milk which makes it appear white is missing in skim milk.
