How to know if soy milk goes bad- What are the signs?

After freezing, it is natural if you see a pale-yellow color on your soy milk. But you can check by smell and sight to know whether it spoiled or not.

  • Stale smell: If you smell sour, your soy milk has started to spoil.
  • Lumpy soy milk: The lumpy soy milk also means it has expired. Good quality soy milk is usually slightly white and smooth, but not lumpy.
  • Expanded carton: When you see the carton that contains soy milk is expanded, your soy milk may go bad and not good for consumption.

What you should know before freezing soy milk

After opening the carton, it is best to freeze soy milk as soon as possible to avoid the risk of spoiling. Keep in mind the followings:

  • Make sure your soy milk is safe for freezing: It should not be opened for more than a couple of days or not over the expiration date.
  • Use the right container: To avoid the water content of the milk separating from the soy milk, you need to choose the right container. Do not choose a glass jar to store soy milk in the freezer as heat and expansion can cause the glass to break. The best solution is a food container with a tight-fitting lid. If you choose a box, be sure to leave at least 1 inch to allow for expansion during freezing.
  • Shake your soy milk well before freezing: This action will help to minimize separation during the freezing process.
  • Label the containers with dates: You should pay attention to the expiration date of soy milk to prevent soy milk from going bad before putting it in the freezer. Calculate 3 months ahead from the day you freeze soy milk to determine the expiration date.
  • Use it before the expiration date.

Another idea is that you should freeze soy milk in batches separately or in small portions. This method will enable you to thaw as much as you want, without thawing a whole container.

What are the best ways to freeze soy milk?

Refrigerating is a perfect way to store soy milk. You can keep it frozen if you want to use it later.

In a cube tray

The best way to ensure the soy milk texture is guaranteed when freezing is to pour the soy milk into the ice tray overnight.

Here are the guidelines:

  • Step 2: Put the soy milk ice cubes in the container
  • Step 3: Label it and put it in the freezer
