Are you wondering how to vacuum seal liquids? Read our article to explore various methods and techniques to retain the taste of your food.

Many of us ask: “what’s the best way to preserve the natural taste and freshness of the food although it’s kept in the refrigerator for weeks”?

Our busy lifestyle has greatly reduced our kitchen hours. Face it! We don’t have time to cook new meals every day, that’s why most of us cope up by preparing food beforehand and store it in the refrigerator.

But sadly, your delicious dishes lose their natural taste when stored. So, how to deal with it? You should vacuum seal your food whether it’s marinated meat or soup. By vacuum sealing, you are preserving the food in its original form.

Do you don’t know how to vacuum seal liquids?  The best method to vacuum seal liquids is by the use of a vacuum sealer machine.

Conventional Storing & Vacuum Sealing

With the vacuum sealing trend at its peak, you are bound to question: Why should you vacuum seal the liquids rather than simply storing them in the refrigerator?

Storing the food in the fridge won’t guarantee that its taste would remain the same after a week or so. The rapid oxidation of food takes place, and hence your food gets spoiled more quickly. But by vacuum sealing, you can avoid it. By sucking out the air from the food bag, you can preserve your food’s taste. If you have an upcoming party, then vacuum-sealing food is the most efficient one.

Why Should You Buy A Liquid Vacuum Sealer?

Let’s first explore why you need a liquid vacuum sealer.

Firstly, it’s a piece of cake for vacuum sealers to seal food like meat and veggies, buts it’s a different story when liquids are in the scene.

Your main priority is to safeguard your food. If you use a regular vacuum sealer, there is a high risk that your stew or soup would be sucked out of the food bag, leading to less food than you originally had.

Secondly, if the liquid food gets sucked out of the food bag, your sealer machine can get damaged. In short, your device’s durability is at risk. Therefore, you should seal liquids with a special vacuum sealer for liquids.

Types Of Vacuum Sealers

Vacuum sealers are of 2 types

  • Chamber Vacuum Sealers
  • External Vacuum Sealers

Chamber Vacuum Sealers

The chamber sealers are perfect for liquid-rich foods like soups, stew, dips, sauces, etc. These machines flawlessly suck out the air without sucking the liquid food. These machines are quite famous but unfortunately, their popularity is limited to only businessmen. For households, they are not compatible because of their unreasonable price and beefy size.

What Are The Various Methods To Vacuum Seal Liquids?

Let’s explore the various methods which can help you on how to vacuum seal liquids.

Vacuum Chamber:

As discussed above, this chamber is specially designed for liquids, when the internal pressure within the chamber reduces, the pressure within the vacuum bag also cuts down. As a result, the liquid doesn’t get sucked into the vacuum sealer and stays inside.

Before putting the liquid into the vacuum bag, you should let it cool down first. Don’t put piping hot food in the bag. This is because as the internal pressure in the bag reduces, the boiling point of the liquid takes a similar turn, leading to the wet food boiling out of the vacuum bag.

Freeze Method

Let’s say, you don’t have a vacuum chamber and you only own a cheap vacuum sealer. You can still be able to vacuum seal the liquid with the freeze method.

In this method, pour the liquid food into the vacuum bag. Then place it in the upright direction in the refrigerator. Once, the liquid is frozen, you can easily vacuum seal the frozen liquid food with your vacuum sealer. In this way, the liquid won’t get sucked into the machine.

Although this method is quite effective, you need to do some prep work for this technique to work. Similarly, you would need plenty of refrigerator space to place the bags upright. If you have issues with this method, you can go for the ice cube method, discussed below!

Ice Cube Method

If you don’t have enough room in your refrigerator, you can use the ice cube method, but like the above freeze method, you also need to prepare beforehand.

Firstly, take a nice ice-cube tray and pour your liquid food into it like sauce, soup, etc. After this, put the ice tray into the refrigerator and wait for the liquid to freeze. When the wet food is completely frozen, take it out from the ice cube tray, and put the ice cubes into the vacuum bag. Seal the bag and store it in the fridge. Easy peasy!
