So far, the public's understanding of milk is a source of protein. In fact, the milk contained so many other important substances that are beneficial to health.

As explained Prof. Dr. Ir. Made Astawan, MS, from the Department of Food Science and Technology Faculty of Agricultural Technology IPB, milk is a food with enough nutrients to complete.

In general, milk consists of water content as much as 87 percent and sisanya or about 13 percent is solid. Solids in milk can be subdivided into fats, carbohydrates, proteins, minerals and vitamins.
