Does whole milk freeze faster than 2 percent or skim milk?

Answer 1

Skim milk has much less fat than normal milk (as you obviously know) and hence much more water concentration, and because fat cannot be frozen (because it is already a solid), the one with more water and no fat freezes much faster than the one with a higher fat concentration in it.

Answer 2

• In general, water with stuff dissolved in it has a lower freezing temperature than pure water. Milk is just water with stuff (fats, sugars, proteins) dissolved in it so it's freezing temperature should be lower than 0 degrees Celsius (the freezing temperature of water).
• Therefore, if you started with both frozen milk and frozen water at say -10 degrees Celsius and started slowly heating them both, the frozen milk will start thawing (melting) before the frozen water.

Answer 3

Milk is mostly water itself. The parts of the milk that aren't water (the fat) will unfreeze faster than the water. You should shake/mix milk up after unfreezing it.

Answer 4

yes, it does. Skim milk has less fat in it, so it can be preserved longer than whole milk.
