Juices are usually the same color as the fruit or vegetable they came from – orange juice is orange, lemonade is yellow, tomato juice is red. So why is milk white? Is it because cows are white? If so, why doesn’t milk have big black spots like cows also have??
Milk gets its white color because of the nutrients it’s made up of! Among the many proteins in milk is one known as casein, which is full of good-for-you calcium that helps keep your bones strong and your teeth healthy. It’s these little units of casein as well as the fat found naturally in milk that give it that recognizable color!
If milk did not have all of these nutrients, it might be a different color. Can you imagine drinking pink or blue or purple milk??!
