Yes, nutritional yeast can go bad in the fridge.

Although keeping nutritional yeast in the refrigerator or freezer may extend its shelf life, it is not necessary. Generally, nutritional yeast should be stored in a cool, clean, and dry location.

Some individuals keep nutritional yeast in the kitchen cupboard until they’re ready to use it and then transfer it to the refrigerator after it becomes open. You can store it on a kitchen shelf, but it will likely last longer if stored somewhere dark.

Nutritional yeast has a shelf life of about two years when kept in a dry, cold, and dark environment that is not exposed to direct sunlight.

It may become worse. Smelling it is an excellent way to determine whether the yeast is no longer edible. If the yeast does not emit its characteristic rotten yeast odor, it may have been stored wrongly and has started to decompose.

Pigmentation of the yellow yeast flakes, along with a changing odor, may signal that the yeast has begun to be infected by other fungi. If you see any of these signs of rotting, it’s best to discard the whole package immediately.

If you see that yeast has begun to expire, avoid tasting it since this may result in severe infections in some individuals.

It is owing to the absence of moisture in the flaky cheese replacement, yet on the other hand, this very dry nature is one of the reasons freezing nutritional yeast is not a good idea.

A sudden warm-up of nutritional yeast may cause condensation to collect on the interior walls of the storage container, causing it to coagulate or even perish if left out too long.

Do not freeze nutritional yeast in its original packing; instead, store it in an airtight container made of a durable material that can survive the cold.

The jar of nutritional yeast should be stored in the deepest section of the freezer, away from freezer vents or fans that might cause freezer burn.
