Vacuum Sealer / Vacum Sealing FAQ
|
What is the main purpose of a vacuum sealer?
A vacuum sealer’s main use is to protect and preserve the lifespan of food. This can be fruits, vegetables, meats and more. By removing the air, life-giving oxygen is removed, which eliminates or slows down spoiling bacteria.
How much longer can vacuum sealed food last over non-vacuum sealed food?
It depends entirely on what is being sealed, but the average lifespan of food can be increased by 3-5 times by being vacuum sealed.
Can I only vacuum seal food?
Although vacuum sealers are primarily used with food, they can be used to package other retail products. Vacuum sealers are commonly used to group and bundle items together for resale. Many people will also use vacuum sealers for space reasons. This can be to bundle material together or for packaging food during a hiking trip.
Does a vacuum sealer eliminate freezer burn?
Vacuum sealers dramatically reduce and eliminate freezer burn. When used correctly, a vacuum sealed bag is impenetrable by the elements.
What is the difference between an external sealer and a chamber sealer?
External sealers use vacuum bags on the outside of the machine. Food is placed in the bag and the open end is inserted into the machine where the air is then removed and the bag is sealed shut.
Chamber vacuum sealers work in a different way. Chamber sealers require the food and the bag to be placed inside the machine. The air within the chamber is then removed, the bag is sealed and the air is returned back to normal. You can see a chamber vacuum sealer in use here.
Can I cook vacuum sealed food in the bag?
Yes. In fact, there are many recipes out there for vacuum bag cooking. This is referred to as "Sous Vide," which translated means "under pressure." Cooking food in a vacuum sealed bag helps keep important nutrients in place and can actually improve the taste of the cooked product.
What is meant by inert gas?
Many chamber vacuum sealers have the option of using inert gas. This means oxygen can be removed by the sealer and an inert gas, such as nitrogen, can be replaced. Inert means that the gas does not support life. This helps extend the life of vacuum-sealed food.
Can I vacuum seal fragile food?
You can, with a chamber sealer. Potato chips are a prime example of this. The air in the bag can be removed and replaced with an inert gas. This allows the food to still be preserved, while allowing gas to be left in the bag, preventing damage.
Can the amount of air removed be adjusted?
Most vacuum sealers allow you to adjust the amount of air removed. This can vary from a low percentage all the way up to 99.99% of the air.
