Can compressed biscuits be preserved for a long time?
Compressed biscuits can be kept for a long time. Because the compressed biscuit has removed the water from the biscuit, the vacuum pump draws out the air inside. Without oxygen, food cannot be oxidized, which improves the preservation quality of food. As a dry food for the army, many people eat compressed biscuits on the March.
