Because of the sealed closures, a glass jar keeps your seeds stable and avoids spoiling. Furthermore, because the glass elements are transparent, you can tell when the chia seed are going rancid.
  • To scoop the seeds, avoid using a spoon. The spoon might transport dust or moisture to your seedlings. If you wish to scoop the seeds out of the container using a spoon, you should only have one spoon and it should be in the container with the seeds. This manner, we can prevent outside moisture and dust.
  • Make certain that the container in which you store your chia seed is completely sealed. When air enters the container, it hastens the rancidification process.
  • Instead of keeping all of the chia seeds together, freeze them in smaller containers for usage within the following few months. This will prevent you from opening the bag and allowing moisture or air inside it.
  • Chia seeds should be stored in a cool, dry area away from sunlight and heat sources. When you open the packaging, ensure sure the seeds are always well wrapped.
