What Color Does Milk Turn When Frozen?

Additionally, keep in mind that you can store frozen breast milk in the freezer for three months.
Why Does Milk Turn Yellow When Frozen?
Milk falls under the class of liquids called emulsion. The composition of milk is a mixture of various things suspended in water.
The fat content of milk is about 5%, and that fat is dispersed through the water as tiny globules surrounded by little proteins.
As typical of proteins, there are a fat-loving part and a water-loving end. The fat-loving part of the protein sticks into the fat, and the water-loving end sticks into the water, which as a result, helps to keep the fat molecules suspended.
Human milk contains a lot of proteins, and when it’s frozen, all these things, which are typically well-suspended and kept separate, begin to become very close together.
During the freezing process, 95% of the water content of milk begins to form big chunky ice crystals and, as a result, wouldn’t want to have proteins and fat in them.
The proteins and the fat get squeezed out of the mixture and then form around this central core of ice. And since all the fat is concentrated in one place, the frozen milk begins to show yellow coloration.
A practical example is the color of butter; butter has a yellow coloration and is derived from milk. The yellow coloration is a result of the collection of all the fat in one place.
