How Do You Know When Flax Seeds Go Bad?
Flax seeds can go bad or rancid due to the exposure to heat, light, and air. When they go bad, they will have an unpleasant odor and taste that is sour or bitter. The oil in the seeds will become rancid and the seeds will no longer have the same texture or crunch. It is recommended to store flax seeds in an airtight container in a cool, dark place to prolong their shelf life.
