How Long Does Soy Milk Last?
Soy milk comes in two different varieties: refrigerated and non-refrigerated. Refrigerated soy milk tends to have a shorter shelf life than non-refrigerated ones.
For refrigerated soy milk, it will need to be refrigerated once it’s opened. In the fridge, it can last 7 to 10 days after the expiration date.
However, it can stay fresh much longer, but that’s not guaranteed. It will depend on the temperature of the fridge, how often the carton is opened and closed, and how long it’s been sitting at room temperature before it’s returned to the fridge.
For soy milk that’s sold on the store shelves, it has a much longer shelf life. Shelf life for non-refrigerated types can have an expiry date of 6 to 9 months.
Again, if the carton has been opened, it will need to be refrigerated after using it. For non-refrigerated soy milk, you’ll want to disregard the expiry date on the carton. That date is for an unopened carton.
Therefore, it’s best to assume that it will last for about 7 to 10 days after opening it. It might last a little longer, but it’s not guaranteed, and you should use your own judgment to tell if it’s gone bad.
