What are two ways to keep food fresh in Antarctica?

Answer 1

The obvious way would be best. The conditions there call for freezing foods. It would not be hard to do.
Keep it in a refrigerator. A lot of fresh food such as fruit will spoil if it is frozen.

Answer 2

Since the temperature in Antarctica is generally below zero, no food left out of doors will 'go bad.' Otherwise, indoors, any food can begin to spoil in the same ways it would spoil anywhere else on earth.

Answer 3

Fresh food is rare in Antarctica, since food is usually frozen in order to transport it to the continent.

The freshest food is grown by scientists in hydroponic situations at the research stations, and is usually consumed as soon as it is ready to eat. Fresh food grown this way includes lettuce, cherry tomatoes, spices and edible flowers.

Answer 4

Because food is stored indoors on Antarctic research stations, refrigeration is used to preserve food.

In field camps, the extreme cold weather is a great substitute for a refrigerator/ freezer.

Answer 5

Refrigerators are handy for keeping food fresh. However, there is no 'fresh' food there -- all food is imported and is either tinned or frozen. Exceptions could be lettuce, tomatoes and spices grown in hydroponic labs on some research stations.
