Expiration & Storage Tips
When does vital wheat gluten expire?
Unopened, vital wheat gluten can last for up to two years if stored in a cool, dry place. It is best to check the best use-by date printed on the package to be sure. Once opened, it should be consumed within six months. Freezing isn't a common practice, but if you seldom use it, you may choose to freeze it, which can extend its lifespan to about one year.
How do you tell if vital wheat gluten is bad?
Telling if vital wheat gluten has gone bad is quite straightforward. If it has developed an off-odor, or you see mold or bugs in it, it’s definitely time to throw it out. Any changes in its color, from its natural cream or white, should also be a warning sign. Check it well before use to make sure it hasn’t clumped together, which can indicate moisture contamination.
Tips for storing vital wheat gluten to extend shelf life
• Keep unopened vital wheat gluten in a cool, dark and dry place.
• After opening, transfer it to an airtight container. This keeps out moisture and pests, and will extend its shelf life.
• If you only use it occasionally, consider refrigerating it. This isn't necessary but can keep it fresh longer.
• For long-term storage, divide it into smaller portions and store it in the freezer in an airtight bag. To defrost, simply leave it at room temperature for a few hours before use.
