What is vacuum sealing and how does it work?
Vacuum sealing is a food preservation method that removes air from the packaging before sealing it. By eliminating air, vacuum sealing slows down the growth of bacteria and fungi, which can spoil food. The vacuum seal is created using specialized machines that suck out the air and seal the package, allowing for prolonged freshness and flavor preservation.
This method is popular among home cooks and food enthusiasts because it not only extends the shelf life of perishable items but also helps in maintaining their original taste, texture, and nutritional value. Vacuum-sealed food can be stored in the refrigerator, freezer, or pantry, depending on the type of food and how long you plan to keep it.
What foods can be vacuum sealed?
Most foods can be vacuum sealed, including meats, poultry, fish, fruits, vegetables, and grains. It is particularly effective for items that benefit from extended freshness, such as meats and fish, which can develop freezer burn when stored improperly. Additionally, vacuum sealing is useful for meal prep, as it allows you to portion out meals in advance.
