What is a vacuum canister?
A vacuum canister is a food storage container that removes air from inside the jar, creating a vacuum seal. This process prevents spoilage and prolongs the freshness of food by minimizing the oxygen exposure that normally leads to oxidation, mold growth, and degradation of flavors. Designed with a specialized lid, these canisters often include a pump or a valve system to effectively create and maintain the vacuum.
These canisters are not only suitable for dry goods like grains, pasta, and snacks, but they also work well with perishable items such as liquids, fruits, and other items that need longer preservation. Available in various sizes and materials, vacuum canisters are a great alternative to traditional storage methods, ensuring that food retains its taste and nutritional value for a longer period.
How do vacuum canisters work?
Vacuum canisters work by using a mechanical or manual method to remove air from the surrounding environment of the food stored within.
