Does milk smell after freezing?

Milk can sometimes develop an off odor after being frozen, even if it is properly sealed and stored. This is due to the breakdown of proteins and fats in the milk by enzymes that are active during the freezing process. The flavor of the milk may also be affected, becoming slightly sweet or sour. Additionally, the texture of the milk may become grainy or icy. To minimize these changes, it is important to freeze milk in airtight containers and to thaw it slowly in the refrigerator.
