What is a vacuum canister and how does it work?
A vacuum canister is a storage container designed to preserve the freshness of food by removing air from the inside. By creating a vacuum seal, these canisters help reduce oxidation, a major cause of spoilage. The mechanism typically involves a vacuum pump that is either built into the lid or is a separate handheld device. When the air is removed, the contents are sealed away from environmental factors like oxygen and moisture.
The vacuum created inside the canister helps to slow down the growth of bacteria and mold, thereby prolonging the shelf life of the stored items. This makes vacuum canisters especially useful for storing coffee, grains, dried fruits, and other perishable items. By minimizing air exposure, the food retains its flavor and nutritional value for a longer period.
