Always there is a confusion between the Skimmed Milk and Toned Milk.

There no confusion they are very well defined such as the:
Skimmed milk- It is the milk left after removing the fat by skimming the cream. Now it contains almost negligible fat, may be 0.2% – 0.4% of fat. Skimmed milk is also called a non-fat milk. It is good for people like to have the milk but no fat for their personal choice.
Toned milk– It prepared and a recipe if followed or it can be called a blended milk. The skim milk powder, buffalo or cow milk and water in a particular proportion. It should contain minimum of 3.0% fat. It is nutritive values are almost pure fresh milk. It is a source of protein.
