How to tell if Sesame Seeds are bad, rotten or spoiled?

Practicing proper hygiene and food safety techniques will help prevent foodborne illness.

Since sesame seeds have a long shelf life if kept dry, it is hard to tell if they have gone bad. The best way is by smell - they will start to smell rancid because of the natural oils breaking down. Once they start to smell they also taste pretty nasty.

When tahini goes bad, it is also given away by the rancid odor that develops. Tahini will naturally separate and become oily on top, this oil should be mixed back in before use (or you can turn the jar upside down for a few days).

For a long term option, both seeds and meal can be frozen in an airtight container.

There are, of course, certain health risks associated with spoiled foods so always remember to practice food safety and enjoy your foods before their shelf life has expired!
