This question comes to the mind of many people: if a cow eats green grass, then why is its milk white? This question arises often, but very few people know the correct answer to it. Let us understand the answer to this question from the point of view of science.
Why is milk white? There are many scientific reasons behind cow's milk being white in colour. The biggest reason is a protein called casein found in milk. This casein protein gives milk its white colour. When light falls on milk, the casein protein scatters that light in different directions, making the milk appear white. It works exactly in the same way as when the rays of the sun fall on the clouds, the clouds also appear white.
Fat also gives whiteness. The fat present in milk also plays an important role in enhancing the white colour. Milk contains small particles of fat, which scatter light here and there. This is also the reason why milk appears white. Also, milk contains many other elements like lactose (sugar), vitamins, and minerals, which contribute to the white colour of milk.
Why doesn't the color of grass come in milk? We often wonder that if a cow eats green grass, then why isn't its milk green? This is because our body, whether it is human or animal, completely digests the food and separates its essential nutrients. The digestive system of a cow also digests the grass and extracts nutrients from it. These nutrients then get mixed in the cow's blood, and milk is produced from it.
How does the body make milk? The cow's body makes milk from the nutrients of food. This process takes place inside the body, in which the color of grass does not come into the milk but the white color is formed from proteins and fats. Apart from this, if some cows have a different diet or they do not eat grass, then the color of their milk can also be slightly yellow or brown.
Simple and precise answer: So, when a cow eats green grass, its color does not come in the milk because the nutrients obtained from the grass are digested and are included in the milk in a different form. The real reason for milk being white is the proteins and fats present in it.
