Hulock Airtight Food Storage Vacuum Containers Set of 6, 3 Piece Round and Rectangular + Vacuum Pump

Why Vacuum Sealing Helps Preserve Food

Vacuum sealed foods will always last longer than other storage methods, aside from canning. Regular plastic wrap, foil, zip-lock bags, and even air tight containers cannot preserve foods as well as vacuum sealing. Why is that?

Food ripens as a result of oxygen exposure. Fruits, vegetables, and meats will begin to spoil after a certain amount of time because they have been exposed to the air. Often mold and bacteria will develop, leaving the food undesirable because of the change in odor, color, and texture of it. Sometimes bacteria can develop without air, but mold does not develop without a healthy supply of oxygen.

When you vacuum seal your food, what you are actually doing is removing the air from the bag. Once the air is removed, mold, and some bacteria, are unable to live or grow. Over time, however, the food you store might spoil if it is not refrigerated or frozen. If you seal your food while it is very fresh, and store it appropriately, it will last longer than if you had used another storage method.

Other methods of storage allow oxygen to creep in through tiny openings. Loosely wrapping your food and putting it in the refrigerator can only save your food for so long. Even if you use an air tight container, the oxygen that is left inside of the container may be enough to allow mold and other bacteria to thrive and spoil your food. Look at it this way, mold eats oxygen to survive and grow. If you do not feed it the oxygen, it will die.
