Preparing your soup at home takes a lot of time to build flavors and create a consistent tasty meal. The same goes for preparing beef or vegetable stocks and broth. This is why spoilage after so much time spent to meticulously prepare and store these liquids is very frustrating.

Liquids are more fragile and prone to spoilage compared to solids food materials. So how do we reconcile this? How do you store liquids without the worry of degradation or spoilage? This method is typically a replication of canning, which is by the use vacuums.

However, since vacuuming works to remove moisture and liquid are in their default state wet, how then is it possible that liquids can be vacuum sealed? How is do you vacuum liquids and remove moisture from an already moist material? Is this possible? The answer is Yes! It is actually possible to vacuum seal liquid. Let's go on this guide to the simple ways and everything you need to know about how to vacuum seal liquids.

What Are The Vacuumable Liquids?

Every liquid is important, either leftover coffee, milk, or wine. However, it is not every liquid in your home that is perishable that is good for storage with a vacuum. Typically, vacuum sealing for liquids usually involve freezable liquids.

Jams and past like semi-solids can be vacuumed using a mason jar and using suction sealer to handle the vacuum as described here. Homemade soups, broth, and stocks that typically require optimal storage for long-term use due to the tedious nature of their preparation process are perfect for the methods of liquid vacuuming discussed in this article.

Avoid vacuuming gas containing liquids like soda and soft drinks. Storing these types of liquids in their original packaging and containers is the best. Vacuuming is not effective and even dangerous due to the gas contained within the liquids.

Things To Do Before Vacuum Sealing Liquid

Unlike solids, you cannot just directly vacuum liquid without taking some very important steps. These pre-vacuum steps are important to avoid the destruction of your vacuum machine and contamination of your soup or beef broth. Before vacuuming the first step to take is FREEZING. Since liquids will run over if sucked in a bag and might cause damage and wastage, freezing first helps transform these liquids into solids which can then be easily vacuumed.

Apart from freezing, if possible, heat the liquid to eliminate pathogens that could hinder long term storage. Also, take note of cleaning the vacuum bags and sterilizing them before use. Without proper sterilization of the vacuum bags, you are exposing your liquids directly to the germs you are trying to avoid, which defeats the purpose of vacuuming. Taking these steps before the vacuum process ensures that vacuuming is effective and if long-term storage is the ultimate goal, then a form of spoilage is avoided.

Methods to Vacuum Seal Liquids

1. Using A Chamber Vacuum Sealer

Chamber style vacuum machine is a suitable process of vacuuming that doesn’t require excessive pre-vacuum steps. It is efficient for vacuum sealing liquids for multipurpose use, including sous vide.  The chamber style vacuum machine involves sealing of liquids in the machine without any freezing done beforehand. The chamber system works with air pressure rather than direct suction.

The process begins with heating your liquid, either soup or broth, and allow to cool in an ice bath. After that, pour the liquid into the vacuum bag. Place the vacuum bag inside the chamber vacuum machine according to the manufacturer’s instructions and allow to vacuum seal. When the process is complete, bring the sealed bag out and store it in a freezer or use or whatever purpose.

2. Freezing Method

When there is no chamber vacuum machine and a normal suction machine at home, using the freezing method is the next best option. The freezing method involves freezing the liquid in a bag before using the suction. You can use a cupcake tin tray or an ice cube tray, for large amounts of soups and broths. For smaller sized soups and liquids, you can directly freeze by placing the soup in the vacuum bag upright in the freezer overnight or until the bag is completely frozen.

If the soup was distributed into cupcake tin trays or with an ice cube tray, carefully remove the solid frozen liquid and dispense into clean vacuum bags. Skip this step if the soup was directly frozen in the vacuum bag. Next, place the vacuum bag (either with the frozen cubes or directly frozen soup) inside the suction vacuum machine and set the timer according to the manufacturer’s description. When the vacuuming is complete, ensure to store the frozen vacuum soup in a freezer until you are ready to use it.

3. Using Mason Jars and Vacuum Pump

Using Mason Jars and vacuum pumps do not require the use of vacuum bags. You can use old jars in your home. Mason jars are suitable for vacuum sealing jams, kimchi, semi-liquids, and even liquids. It is a cheaper less expensive vacuum sealing method for liquids. No freezing is necessary with Mason jars.

The process involves placing a lid on the mason jar without its ring cover. Poke the middle of the lid with a pin. Use a tab check on the hole and place the vacuum pump on the tab check and begin vacuuming. When vacuuming is complete, remove the pump and secure the lid with the ring cover. You can store foods long term for as long as possible.

Vacuuming sealing liquids is very efficient in keeping non-solid food materials fresh for long term storage. It is no longer a hassle to prepare stock or soups regularly as the freezing option is quite convenient. If you make a large batch of jam and you want to sell the excess, mason jars are quite cheap and resourceful. You can share soups with neighbors and family and avoid purchasing canned soups. Either you have enough to afford a chamber vacuum or little to purchase a vacuum pump, each and every method described in detail is designed for both low budgets and high budgets.
