Does Nutritional Yeast Go Bad?
Nutritional yeast is a versatile ingredient and useful part of many plant-based diets. Because it tastes like cheese and is full of nutrients, it is often added to foods to make them taste better and give them more nutrients.
It can lose potency or become stale over time, especially when exposed to moisture or heat. It will save you money and protect your health if you know how to handle and store it.
What Is Nutritional Yeast and Why Shelf Life Matters
It is made from the same kind of yeast cells that are used to make brewer's yeast and baker's yeast, but they have been changed so that they are no longer active. In other words, it doesn't make dough rise, but it does add umami flavors, protein, and B vitamins to food.

Is It Harmful to Use Expired Yeast?
Depending on the type of yeast and how it was stored, it may or may not be safe to use. Active yeast is used in baking, and it needs to be fresh in order to work.

Check for mold: Look for dark spots, clumps, or mold growth on the flakes.

Smell before use: If it smells sour or musty, it might not be safe.

Watch the texture: The flakes that are sticky or damp may have been taken in water.
-
Storage tip: Keeping it in a dry, airtight container is the safest thing you can do.
