Decide on the portions you want to vacuum seal. It’s always better to seal liquids in smaller portions to avoid wasting food. Typically, portion sizes can range from 1 cup to 4 cups, depending on the recipe or intended use.
Steps to Vacuum Seal Liquids
Though vacuum sealing liquids can be challenging, following these systematic steps will simplify the process.
Step 1: Pre-Freeze the Liquid
One of the most effective strategies for vacuum sealing liquids is to pre-freeze them slightly. Here’s how to go about it:
- Pour the liquid into a container: Use a hard plastic container or an ice cube tray for smaller portions.
- Freeze until slushy: Allow the liquid to freeze just enough to create a slushy consistency, usually about 2-3 hours.
- Remove from the freezer: The liquid should be firm enough to avoid spilling but still putty-like for vacuum sealing.
Step 2: Choose the Right Bag
Selecting a suitable vacuum sealer bag is crucial when sealing liquids. Opt for heavy-duty vacuum bags or liquid barrier bags, which significantly reduce the chances of leaks. These bags are thicker and designed to handle moist contents without breaking during the sealing process.
Step 3: Use a Liquid Blocker (Optional)
If you’re particularly worried about liquid seeping into the vacuum sealer, consider using a liquid blocker. This handy tool fits within the bag and serves as a barrier preventing spills while you seal the bag.
Step 4: Fill the Bag
Once you’ve prepared your liquid, it’s time to fill your vacuum sealer bag. Follow these tips:
- Leave Space at the Top: Make sure to leave about 2-3 inches of space at the top to accommodate the sealing process. This ensures a tight and effective seal.
- Avoid Overfilling: An overfilled bag may not seal properly. Measure the liquid portion accordingly.
Step 5: Pre-Seal for Liquids
To ensure the vacuum sealer can operate effectively, you may need to perform a pre-seal.
- Insert the bag into the vacuum sealer: Place the open end of the bag into the machine’s sealing area.
- Engage the pre-seal option: If your vacuum sealer has a pre-seal button, use it to seal the bag without vacuuming. This step is crucial to prevent the liquid from being sucked into the machine.

What is vacuum sealing and how does it work with liquids?
Vacuum sealing is a food preservation method that eliminates air from a packaging bag or container, creating a sealed environment that helps to prolong the freshness of the food. This process works by using a vacuum sealer that sucks out the air and then heat-seals the bag to ensure no air can re-enter. When it comes to liquids, special considerations need to be taken into account to prevent spills or damage to the vacuum sealer.
When sealing liquids, it is crucial to use a technique that minimizes the chance of liquid being sucked into the vacuum sealer. Many vacuum sealers come with a liquid setting, which allows for a slower draw of air to accommodate the presence of liquids. Additionally, specific types of bags, such as those designed specifically for liquids, can improve the sealing process and reduce mess.
Can I vacuum seal soups and sauces?
Yes, you can vacuum seal soups and sauces, but it requires careful handling to avoid mess and ensure a proper seal. It’s recommended to first freeze the soup or sauce in a shallow container until it reaches a slushy consistency. This prevents the liquid from being drawn into the vacuum sealer during the sealing process, which can damage the machine.
Once the soup or sauce is partially frozen, transfer it to a vacuum sealing bag or container. Use the vacuum sealer on the appropriate setting for liquids, ensuring a tight seal. If possible, leave some space at the top of the bag or container to allow for expansion and prevent spillage during sealing.
