If Does soy milk go bad? is a question that bothers you, the short answer is pretty obvious: yes, it does. Soy milk does spoil similarly to cow’s milk. When it comes to shelf life of that non-dairy milk, it depends on how it’s stored. If you’re storing it properly, it will be fine for a little longer than usually, but you can’t expect any miracles here. It’s also pretty easy to tell if soy milk has already gone bad. On a side note: only a few brands sell gluten free soy milk, so if you suffer from celiac disease, check the package before buying.
How To Store Soy Milk
While the soy milk is unopened, proper storage depends on the kind of soy milk. If it’s shelf stable soy milk (sold unrefrigerated) then you should store it in a cool, dry place, e.g. in the pantry. Storing it in the fridge isn’t a bad idea, but it won’t help much that much. If your soy milk was sold refrigerated, that’s another story. It has to be kept in the fridge.
Once you open the carton, it has to kept in the fridge. If it’ll be stored in a warmer place, its shelf life will shorten noticeably. Please note that, if possible, soy milk should be stored in the middle of the fridge, away from the door. The closer the door, the higher temperature fluctuations which you want to avoid.
If you need to store soy milk for an extended period of time, you can also freeze it. Please note that soy milk might lose some of its taste and texture after thawing. It’s best to use thawed soy milk only in cooked dishes. This way they change of texture won’t be noticeable. When it comes to thawing, choose the fridge, not the countertop.
Shelf Life Of Soy Milk
While the soy milk is unopened, shelf life depends on whether the milk is shelf stable, or not. If it’s shelf stable (sold unrefrigerated) it should be fine (when stored properly) for at least a year. If your soy milk is sold refrigerated it’ll be fine for about a week, maybe two after the date (best use-by, use-by, best by) on the package. If the soy milk is opened and stored properly, it should be fine for at least a week, maybe two. If it won’t be stored well, it might spoil within a couple of days. When you freeze soy milk it won’t go bad, so theoretically you can store it for an indefinite period of time. Please note, however, that it’s recommended to freeze soy milk only for a couple of months, to preserve possibly good quality.
How To Tell If Soy Milk Is Bad
It’s pretty easy to tell if soy milk (gluten free or not) has gone bad. The first thing you should do is to smell the soy product. If it has an off odor it’s probably spoiled and you should discard it. Fresh soy milk should have a mild smell (you probably know how fresh soy milk smells like), so if you notice a difference in smell, the milk is probably off. You should also examine the package and the liquid itself. If the package is abnormally bloated you can be almost sure that the milk is spoiled. You should always pour the milk into a glass or a cup before drinking. There are at least two reasons why you should do that. The first one is that if you drink soy milk directly from the package, some bacteria from your mouth can get into the milk and accelerate the process of spoilage. The second one is that you can easily examine the texture of the milk. If the milk is thick, has lumps or curds (similarly to cow’s milk) then it’s spoiled and it should be thrown away.
As you can see, soy milk does go bad. If it’s stored properly it can stay fine for a longer period of time. If you need to store it for an extended period of time you can always freeze it. Please bear in mind that only a couple brands produce gluten free soy milk, so choose wisely according to your needs (gluten free soy milk isn’t that tasty as the normal one).
