Can You Vacuum Seal Liquids? (4 Simple Ways To Do It)

Vacuum sealing is a highly reliable method of preserving foods. You can preserve meats, cheese, rice, veggies, fruits, and many other things for as long as 2 weeks, 3 months, and even years in this way. This has made vacuum sealers grow in popularity in many kitchens.

Read along to get your question answered and learn four simple ways of doing it right.

If you were to simply seal liquids using a vacuum sealer, they would be sucked right into the machine which would ruin it and waste your food at the same time. This is where freezing comes in.

The freezing method will require you to freeze your liquids before vacuum sealing them. This keeps them solid and hard to be pulled into the machine.

Freezing liquids before sealing is also efficient because liquids expand after freezing. This prevents any chances of your liquids expanding later after sealing which could compromise the seal.

So what you do is: First pour your liquids into a bag. Place the open bag in the freezer and let it turn solid. Pick it up and vacuum seal it with your vacuum sealer machine.

Ice cubes

An alternative to freezing is making ice cubes. Pour your liquids into an ice cube tray and put them in the fridge.

When they are solid, put them in the bag, and vacuum seal it.

Chamber Vacuum Sealer

A chamber vacuum sealer is bigger and more expensive than a vacuum sealer machine. It can seal many bags at once and it’s very efficient at sealing.

The good thing about this machine is that it will not draw air out of the bag so your liquids will stay intact. It will instead work by reducing pressure inside the bag which will pull out only the air gradually.

The liquids are left in the bag as the air is vacuumed out and the bag is sealed shut. The process is fast and there is no mess left to clean. This one is especially useful for sous vide.

It works great for restaurants and you can invest in one if you frequently seal liquids (and other foods too) because it is worth it and a time saver.

Liquid blocker strips

You can buy some liquid blocker strips for the times you want to vacuum seal liquids. The strips are small plastic apparatus that can fit across vacuum bags. They are designed to keep the liquid down as you vacuum seal to prevent it from getting pulled out.

What you do is you put the contents in a bag, then place the strip at the top. It should be above the liquid but below the seal.

You can then vacuum seal your bag. The strip will allow air to be drawn out while keeping the liquid in the bag.

It will also be sealed inside the bag together with the liquid. You will need to have different strips for each bag if you are sealing multiple bags.

Liquid blocker strips can usually withstand high temperatures so they are safe for sous vide. Another good thing about the strips is that they are washable. You can wash them after use and keep them for later use.

Benefits of vacuum sealing liquids

Vacuum sealing your liquids will be highly beneficial to you in many ways and the best of all is how it will preserve the freshness and taste.

Whether you prepared more soup or have some leftover stew, you can vacuum seal it for another day. The method will keep all the flavor and freshness of your food intact until when you need to eat it again.

Liquids can be vacuum sealed and it’s so easy and mess-free at the same time. You only need to choose the method that works best for you.

You can use liquid block strips to keep the liquids from coming up, freeze the liquids before vacuum sealing, turn them into ice cubes first, or simply use the chamber vacuum sealing machine.

The chamber vacuum sealing machine is a more expensive method compared to the rest but investing in one is worth it if you seal many liquids frequently. It is fast and very efficient for many bags.
