Vacuum sealers are devices that remove air from bags or containers to create an airtight seal. This process helps to preserve food by preventing the growth of bacteria and mold, which can cause spoilage. Vacuum sealers can be used to store a variety of foods, including meats, cheeses, vegetables, and fruits.
Vacuum sealing offers several benefits. First, it can extend the shelf life of food by up to five times. This is because the removal of oxygen inhibits the growth of bacteria and mold. Second, vacuum sealing can help to preserve the flavor and nutrients of food. By removing the air, vacuum sealing helps to prevent oxidation, which can cause food to lose its flavor and nutrients. Third, vacuum sealing can help to reduce freezer burn. Freezer burn occurs when food is exposed to air, which causes the food to dry out and lose its flavor. Vacuum sealing can help to prevent freezer burn by creating an airtight seal that prevents air from reaching the food.
