Why does food go off more slowly in a freezer than fridge?

The main reason why food goes off more slowly in a freezer than a fridge is because of the temperature. The colder the temperature, the slower the growth of bacteria and other microorganisms that cause food to spoil. The optimum temperature for bacterial growth is between 40°F and 140°F, so food that is kept below 40°F will last much longer than food that is kept at room temperature.

In addition to the lower temperature, freezers also have a lower humidity level than fridges. This is important because bacteria need moisture to grow, so reducing the humidity level can help to slow down the spoilage process.

Finally, freezers also often have circulating fans that help to distribute the cold air evenly throughout the freezer. This helps to prevent warm spots from developing, which could allow bacteria to grow.

As a general rule, food that is kept in the freezer will last for much longer than food that is kept in the fridge. However, it is still important to check food for signs of spoilage before eating it, even if it has been frozen.
