The white color of milk is due to the presence of caseins. Caseins are one of the main types of protein in milk which cluster together with calcium and phosphate to form tiny particles called micelles. When light hits these casein micelles it causes the light to refract and scatter resulting in milk appearing white.

As, milk reflects all the light of all colours falling on it and does not absorb any colour. Hence, it appears white in colour.

Milk is naturally white, thanks to the interaction between water, fat and proteins that mix together to form tiny particles which reflect light.

Milk is processed into a variety of products such as cream, butter, yogurt, kefir, ice cream and cheese. Modern industrial processes use milk to produce casein, whey protein, lactose, condensed milk, powdered milk, and many other food-additives and industrial products.
