Expiration & Storage Tips
When does yellow mustard seeds expire?
Unopened, a package of yellow mustard seeds can last for about 2 to 3 years beyond the printed date. Once opened, they should be used within 1 to 2 years for best flavor. Refrigerating or freezing can further extend the shelf life, potentially keeping the seeds fresh for up to 4 years.
How do you tell if yellow mustard seeds is bad?
Time and exposure are the main factors that can cause yellow mustard seeds to go bad. Look out for signs like a dull appearance, loss of color, and a weak aroma. A musty, stale, or generally off smell is a strong indicator that they've passed their prime. If you notice any mold or unusual discoloration, that's also a signal to toss them out.
Tips for storing yellow mustard seeds to extend shelf life
• Always make sure to store yellow mustard seeds in a cool, dry, and dark place to preserve their natural oils and maintain their flavor.
• Use a glass jar with an airtight lid to protect them from moisture, air, and other contaminants.
• If you're going to refrigerate them, pack the seeds tightly in a freezer bag to minimize air exposure.
• To avoid contamination, always use clean, dry utensils whenever handling the seeds.
• For long-term storage, consider freezing the seeds. They freeze well and when stored properly in the freezer, their shelf life is almost indefinite.
