The importance of creating a vacuum when food is canned, is that it minimizes or eliminates the exposure of the food to oxygen. When foods are exposed to oxygen, they begin to spoil and decompose, and bacteria grow rapidly. At that point, they generally have poisonous levels of bacteria. By creating the vacuum, the food doesn't grow bacteria until the vacuum seal is opened.
