To best preserve nutritional yeast and its B vitamins, store it in a dark, airtight container in a cool, dry place.
Here's a more detailed breakdown:
-
Container:
- Darkness is key: Use a dark glass or ceramic container. This protects the nutritional yeast from light exposure, which can degrade the B vitamins.
- Airtight seal: Ensure the container has a tight-fitting lid to prevent moisture from entering. Moisture can cause the nutritional yeast to clump and potentially spoil.
-
Location:
- Cool and dry: Store the container in a cool, dry place away from direct sunlight and heat. A pantry or cupboard works well. Avoid storing it near the stove or in the refrigerator, as temperature fluctuations and humidity can negatively impact its quality.
-
Shelf Life:
- Properly stored, nutritional yeast can last for up to two years. Check the "best by" date on the package as a guideline, but your senses are the best indicator. If it smells or tastes off, discard it.
-
Signs of Spoilage:
- Clumping: If the nutritional yeast becomes clumpy, it might indicate moisture exposure. While still potentially usable if it smells and tastes normal, it's best to use it quickly.
- Off smell or taste: If the nutritional yeast develops a strange or unpleasant odor or taste, discard it.
By following these storage guidelines, you can maximize the shelf life and maintain the nutritional value of your nutritional yeast.
