It is officially recommended that you discard opened soy milk that has been left unrefrigerated at room temperature for more than 2 hours.

After this time frame, it is considered unsafe because bacteria have thrived on it.

However, shelf-stable sealed soy milk can sit on the counter for as long as 3 to 6 months

And till you burst it open but if bought from the store at the refrigerated section, keep it refrigerated even while unopened.

If left out, and opened for too long, soy milk will begin to smell funny and get clumpy too.

Most of it has stayed in overnight and this is solely dependent on the temperature.

It will not make you sick though, but there will be an alteration in the texture and taste.

Soy milk can either be refrigerated or shell-stable depending on the packaging type and how the liquid is processed.

Once opened, refrigerated soy milk should be consumed within 5 days.

For shelf-stable packaging, it should be refrigerated only once opened.

While bottled packaging, keep it refrigerated even while unopened.

After opening, always keep soy milk sealed and refrigerated.

If you cannot reseal the original packaging, transfer it to a mason jar or an airtight before refrigerating.

Most brands make soy milk stay at least 12 months extra after the production date

With proper storage, it will keep for some extra time.

The refrigerator is one good method of storage, especially for opened soy milk.

Be sure to keep it sealed in an airtight container after opening,

And refrigerate in the refrigerator with a temperature less than 40⁰F.

provided the package is undamaged, with no dent, no bloat, no burst, and no leaks.

The printed date is just the manufacturer’s estimate of how long it will stay of top quality.

If the right method is followed, it will last even longer, if not, it will spoil even before the estimated date.

So, long as soy milk has no off odour, or flavour in its appearance, it is still safe to consume even after the printed date.
