Milk also contains various vitamins and minerals, including calcium, phosphorus, and vitamins D and B12. The fat content in milk can vary, but it’s typically around 3-4% in whole milk.

The Freezing Process

When milk is frozen, the water molecules inside the liquid form ice crystals. This process can affect the structure and texture of the milk proteins and fats. The rate of freezing is critical in determining the quality of the frozen milk. Quick freezing, also known as flash freezing, helps preserve the milk’s texture and nutritional value by forming small ice crystals. On the other hand, slow freezing can lead to the formation of larger ice crystals, which can cause the milk to become watery or separate upon thawing.

Effects on Nutritional Value

Freezing milk can affect its nutritional value, but the impact is generally minimal. The vitamin content in milk can be affected by freezing, with water-soluble vitamins like vitamin C and B12 being more susceptible to degradation.
