Chia Seeds do not Require Any Kind of Cold Storage in Order to be Kept.
Chia seeds have a long shelf life when stored in an airtight container at room temperature. Chia seeds can be kept in the cupboard for up to two years before they go bad, and they can be stored in the refrigerator for up to four years. It would be very expensive to buy seeds every year for four years.
It is impossible to prevent chia seeds from becoming rancid. As they oxidize, they decompose into more straightforward compounds. To delay this natural process, it is best to store the seeds in an airtight container and keep them away from moisture.
