How Do Vacuum Sealers Work: A Comprehensive Guide to Food Preservation
Vacuum sealers work by removing the air from a package and sealing it with an airtight seal. This is accomplished through the use of a vacuum pump, which sucks the air out of the package, and a heating element, which seals the package shut. By removing the air, vacuum sealers prevent the growth of bacteria and mold and extend the shelf life of food, as well as preventing freezer burn.
