Can You Freeze Soya Milk?

As one of the most popular and longstanding alternatives to dairy milk, soya milk is a cupboard staple for people who follow a plant-based diet. It’s also free from cholesterol and low in saturated fat, making it a healthy alternative to dairy-based milk.

If you’ve purchased soya milk in bulk to save yourself some money, you will be looking for the best way to preserve it and extend its shelf life. So, can you freeze soya milk? Let’s find out now.

The Quick Answer

Yes, you can freeze soya milk. Soya milk can be frozen for around 3 months. To freeze soya milk, place the carton in the freezer. If you’re don’t want to freeze the whole carton, you will need to transfer the soya milk to an airtight container before freezing. 

How to Freeze Soya Milk

While it’s perfectly safe to freeze soya milk, doing so may cause it to separate. As long as you stir it well after defrosting, you will be able to bring it back to its desired consistency.

Some people think that soya milk loses some of its flavours once it has been frozen and believe it tastes a little watery. But if you’re okay with a slight loss of taste and a change in consistency, freezing soya milk is a good way of preventing it from spoiling. 

If you’re freezing shop-bought soya milk, it’s best to place an unopened carton directly in the freezer while it’s still fresh. This will preserve it for up to three months.

However, if you want to freeze an opened carton (or, indeed, homemade soya milk), follow the simple steps below: 

  1. Transfer to an Airtight Container
    Pour the soya milk into a clean airtight container. Leave at least one inch from the top of the container to cater for expansion in the freezer. Then, place the lid on the container. 
  2. Label and Freeze
    Write the date that you purchased the soya milk, as well as its use-by date, before placing it on a flat surface in the freezer. Remember, you can freeze soya milk for around three months. 

3 Tips for Freezing Soya Milk

Now you know how to freeze it, we’ve got our 3 top tips which we strongly recommend following when freezing soya milk to have the best results:

  • Stir Well After Defrosting – You will probably find that your soya milk has separated after it has frozen. While this is nothing to be alarmed about, you will need to stir it well after defrosting it to try and return it to its desired consistency. It won’t always be fully restored to its pre-freezer consistency, so don’t be too disappointed if it’s not silky smooth! 
  • Opt for Long-Life Soya Milk Instead – If you’re worried about your soya milk going bad, you could always opt for long-life cartons instead of those that need to be refrigerated. This is a particularly good idea if you buy soya milk in bulk. While long-life soya milk still needs to be used within a matter of days once opened, unopened cartons will be fine on the shelf for months, removing the need to freeze them. 
  • Use it in Smoothies – Frozen soya milk is an ideal base for delicious, plant-based smoothies. And because it is blended with a range of fruits and vegetables, its texture isn’t overly important. Equally, if you use frozen soya milk in smoothies, you don’t need to defrost it before adding it to your blender. 

How Long Can You Freeze Soya Milk?

You can freeze soya milk for around three months. 

Once opened, soya milk needs to be used within 3-4 days from the fridge, so freezing it is an excellent way of extending its shelf life. However, as introduced, buying long-life soya milk cartons is a better alternative to freezing them, as it won’t alter the consistency or taste of the milk.

You Can Freeze Soya Milk for up to 3 Months

How Do You Defrost Soya Milk?

Should you use soya milk in smoothies and certain desserts, you don’t need to defrost it. However, to defrost soya milk, remove it from the freezer and allow it to thaw in the fridge. This will take several hours.

Once you’re happy that the soya milk has thawed, you will need to stir it well to help bring it back to its desired consistency. 

Can You Refreeze Soya Milk?

Due to the fact that soya milk splits during the initial freezing process, it’s not a good idea to freeze it a second time. Also, the high water content of soya milk means that it can go watery during the freezing process, which will affect its sweet taste.

If you only use small amounts of soya milk once in a while, it’s better to freeze it in batches, as this allows you to remove only what you need from the freezer, reducing the risk of wasting the milk.  

Does Soya Milk Freeze Well?

Soya milk doesn’t freeze very well, and you should only freeze it if you’re worried about wasting an opened carton or if it’s about to reach its use-by date.

Instead of freezing soya milk to preserve it, we recommend purchasing long-life soya milk that has a much longer shelf-life and will be good for several months unopened without freezing it.
