Ant Manor February 26: Why are there many small holes in the fresh tofu after it is frozen into frozen tofu?

Question: After freezing fresh tofu into frozen tofu, why are there many small holes on it?

Answer: Due to the volume change of water

Answer analysis:

1. The reason why there are many small holes in frozen tofu is because the water in the tofu freezes during the freezing process and expands in volume, causing the original small holes to become enlarged;

2. Tofu contains a lot of water, which will solidify into small ice crystals during the freezing process;

3. At the same time, the volume increases. These small ice crystals squeeze the whole piece of tofu into a honeycomb-like shape. When the tofu is thawed, the originally solidified small ice crystals melt into water and the volume decreases.
