Signs of Spoilage
Significant dulling or fading of color, a musty or 'off' smell, presence of mold (very rare if properly sealed), or signs of insect activity.
How to Check
Visually inspect for any discoloration, mold, or foreign matter. A faint musty smell would indicate degradation. While safe, quality will be severely diminished.
Storage Tips
The 'best by' date on the package typically refers to peak quality, not safety. Whole spices generally retain their quality longer than ground spices. Store in a cool, dark, dry place.

Signs of Spoilage
Significant loss of their characteristic pungent aroma and flavor, dull or faded yellow color, a musty or stale smell, clumping (due to moisture), or visible signs of insect infestation (small holes, webbing, live insects).
How to Check
-
Smell Test: Rub a few seeds between your fingers and smell. Fresh mustard seeds should have a mild, earthy, slightly pungent aroma. If it smells faint, musty, or like nothing, its potency is significantly reduced.
-
Visual Inspection: Look for a bright yellow color. If the seeds appear dull, faded, or discolored, or if there's any sign of mold or insect activity, discard them. Seeds should be free-flowing, not clumped.
-
Taste Test (small amount): Crush a few seeds and taste. They should have a characteristic mild, earthy, slightly pungent flavor. If they taste bland, bitter, or stale, they are past their prime for culinary use.
Storage Tips
Store in an airtight container (glass jars with tight-fitting lids are ideal) in a cool, dark, dry place, away from direct sunlight, heat sources (like above a stove), and moisture. Grinding seeds just before use will maximize their flavor and aroma.
