What is vacuum sealing, and how does it work?
Vacuum sealing is a method of packaging food where air is removed from the bag or container before sealing it. This process creates a vacuum, which helps to preserve food by reducing its exposure to oxygen, mold, and bacteria. It also minimizes freezer burn and helps to maintain flavor, texture, and nutrients over time.
The process typically involves using a vacuum sealing machine that can either be a countertop model or a handheld version. The food is placed inside a specially designed plastic bag, which the machine seals tightly after removing the air. This method is widely used in both home kitchens and commercial settings to extend the shelf life of food items.
What foods can be vacuum sealed?
A wide variety of foods can be vacuum sealed, including meats, fish, vegetables, fruits, and even dry goods like pasta and rice.
