The unsaturated oils in nuts and whole grains go ‘rancid’ over time. Exposure to light and variation in heat accellerate the process, but 6 months or so is about as long as something like that keeps.

Toss them, sesame seeds have a high oil content that can cause them to go rancid very quickly (like sesame seed oil). Next time, store them in the refrigerator. They will last a long long time! The taste is neutral, slightly nutty flavor.

If it tastes rancid and is several years old, then it’s probably bad. Throw it away!

No. The oil in the seeds is rancid. Throw it out and try again with new.
