How long soy milk goes terrible depends on where it is stored and whether it is opened or unopened.

Types	Last For
Opened soy milk cartons, sold in refrigerated	7-10 days
Unopened soy milk carton, sold in refrigerated	1 week after the date on the package
Opened soy milk cartons, sold in unrefrigerated	7-10 days
Unopened soy milk carton, sold in unrefrigerated	3-4 weeks after the date on the package

Whether you put soy milk in the fridge or not, if they are unopened, you can store them up to 1 to 4 weeks after the date on the package. Thus, if you don’t tend to use it, don’t open them.

However, once they are opened, you had better store them in the fridge for better taste, although putting them in the refrigerator or not doesn’t matter anymore. Shelf-stable soy milk will keep them safe for about 7 to 10 days.

Remember to check the day on the package because there are some significant differences between confusing terms: “best by day,” “expiration day” and “use by day.”

How To Store Soy Milk In The Right Way?

Here are some tips you must consider when storing your soy milk. Let’s check them out!

At The Room Temperature

If you have opened soy milk bottles, please close them tightly after using them.
Keep the soy milk product in a cool, dark place, away from direct sunlight, because stable storage will help you keep soy milk for a longer time.
Keep them away from heat sources like stoves because the rising temperature will stimulate bacteria to grow faster in the soy milk, even being unopened.

In The Fridge

Put Soy Milk In Cool Places — Put your soy milk in cool places for longer preservation!

Your unopened soy milk has been safe after the expiration day on the package if you keep it refrigerated at all times.
To maximize the shelf, store your soy milk in the main body of the fridge, don’t put it on the fridge door because the temperature is warmer than in the main body.
Keep your opened soy milk bottles tightly closed to prevent bacteria invasion from the other foods or the fridge.
You also can freeze your soy milk for longer storage.

Best Ways To Freeze Soy Milk

Each brand and manufacturer will have a distinctive recipe so that frozen soy milk can have mixed results partly depending on this.

If you want, here are some highly recommended ways to freeze your soy milk for further consumption.

Use plastic food-safe and freezer-safe containers with a sealable lid. It can be the best time-saving method; pour your soy milk, close the lid, and put the container in the freezer.

However, you need to make sure that you leave a space in the container because soy milk is mainly water, so it will expand a lot when freezing.

Use freezer bags. If you are worried about the small space of your fridge, using a freezer bag may be a feasible solution for you, but notice that you should leave space in the bag and a little around it in the freezer.

Use a silicone ice cube tray. Using an ice cube tray to freeze your milk is an excellent idea. You can take a few cubes if you need to whip up a quick side dish for breakfast meals, such as smoothie. You don’t need to defrost whole frozen soy milk.

The silicone ice cube tray can help ice cubes being sticky in the tray, so you can pop them out easily to transfer to the freezer bag and continue with the others.

Notes When Freezing Soy Milk!

Freezing soy milk is not difficult, but there are also some notes for you to get a better result!. Let’s see!

Freeze your soy milk as soon as you’ve opened the carton to reduce the risk of spoiling, and you can use it for a longer time after thawing.
Don’t forget to leave plenty of space for expanding soy milk.
Never freezer soy milk in something rigid as the expansion will cause the jar to crack.
Just thaw enough amount that you use.
After thawing, the texture and color of frozen soy milk will change. The surface will be separate, and the color will be pale yellow. This is perfectly natural!!
Remember to label the expiration day to your soy mail containers.
Don’t refreeze the defrosted soy milk if you need to use all thawed amounts or discard the abundant milk.
