Expiration & Storage Tips
When does nutritional yeast expire?
The unopened package of nutritional yeast can last anywhere from 1 to 2 years past the printed expiration date when stored in a cool, dry place. Once the package has been opened, the nutritional yeast remains good for about 6 to 12 months. For extended shelf life, you can freeze nutritional yeast which can increase its durability to 2 years or more.
How do you tell if nutritional yeast is bad?
Check the smell and color of the nutritional yeast. If it develops a foul or off-putting smell, it has likely gone bad. The color should be a vibrant yellow. If it has turned dark or has visible mold, discard it immediately. Also, if the texture has changed and it's no longer flaky but clumpy, it's best not to use it.
Tips for storing nutritional yeast to extend shelf life
• Always reseal the package tightly after each use to prevent moisture and air entering.
• Store in a cool, dry place away from sunlight. Nutritional yeast does well in temperatures below 77°F (25°C).
• If you use it infrequently, you can store nutritional yeast in the freezer in a tightly sealed container to keep it fresh. When ready to use, just scoop out the amount you need and return the rest to the freezer immediately.
• Keep your storage containers clean. Cross-contamination can lead to spoilage.
