What is vacuum sealing and how does it work?
Vacuum sealing is a method of removing air from packaging to create an airtight seal around the food. This process significantly reduces the amount of oxygen in the package, which in turn slows down the growth of bacteria and mold, and decreases the risk of freezer burn. By sealing moist food, you can effectively extend its shelf life and maintain its quality for longer periods.
The vacuum sealing process typically involves placing the food in a vacuum bag, placing the bag into a vacuum sealer, and then activating the machine to remove the air. Once the air is removed, the bag is sealed tightly, ensuring that no air can re-enter. This not only preserves freshness but also helps in marinating and infusing flavors in foods.
Is vacuum sealing suitable for all types of moist foods?
While vacuum sealing is highly effective for many types of moist foods, not all items are equally suitable for the process.
