"Best by" and "sell by" dates on sesame seeds typically indicate peak quality, not a hard safety cutoff. If sesame seeds smells normal, shows no visible mold or discoloration, and has been stored properly, it is often safe shortly past the printed date. However, use your judgment and when in doubt, discard it.

Freezer burn on sesame seeds is caused by air reaching the food's surface and causes dry, discolored patches. Freezer-burned sesame seeds is safe to eat — it is a quality issue, not a safety issue. The affected areas may have an off flavor or dry texture. You can trim away freezer-burned portions before cooking. To prevent freezer burn, use airtight packaging and remove as much air as possible before freezing.
What does it mean if sesame seeds has changed color or texture?
Minor color changes in sesame seeds may be natural and do not always indicate spoilage. However, significant discoloration, mold growth, unusual sliminess, or a major texture change typically means the product has degraded. If the change is accompanied by an off smell, discard the product. When only the color has shifted slightly and everything else seems normal, the product may still be usable but is past peak quality.
