What is vacuum sealing and how does it work?
Vacuum sealing is a method of removing air from a package before sealing it tightly, thereby creating a vacuum environment that inhibits the growth of bacteria and molds. The process involves placing food items in a specially designed bag, using a vacuum sealer to suck out the air, and then sealing the bag to prevent oxygen from re-entering. This technique helps to preserve the freshness, flavor, and nutritional value of the food for a longer period.
The absence of air significantly slows down the spoilage process, allowing you to store food safely for weeks, months, or even years, depending on the type of food. Vacuum sealing is commonly used for meats, vegetables, fruits, and even liquids, making it a versatile option for food preservation. By effectively sealing in the natural moisture and preventing freezer burn, vacuum sealing ensures that your food remains as close to its original condition as possible.
