Understanding the Importance of Proper Storage

Proper storage of mustard is crucial to maintain its flavor, texture, and overall quality. Improper storage can lead to flavor loss, discoloration, and even spoilage. By following the recommended storage guidelines, you can prolong the shelf life of unopened mustard and enjoy its delicious taste for longer.

Factors Affecting Mustard Shelf Life

Several factors can impact the shelf life of unopened mustard:

4. Check Expiry Dates
