How To Store Chia Seeds

Since chia  have a long shelf life, they’re easy to store. You can opt to portion the seeds into weekly parts and keep them in your pantry and the rest in the fridge or freezer. Take note of the following when storing chia seeds.

A mason jar would work perfectly in this case. If you don’t have one, you can use a plastic plate. However, remember glass provides better stable storage conditions than plastic, preventing spoilage.

Besides, if the vessel is transparent, you can easily notice any change in your seeds. And it will be easier to remember the seeds and use them if you keep seeing them in the jar than when using plastic packaging that doesn’t let you see the contents inside.


Sealing tight containers containing chia  is crucial in preventing air from getting in, which can speed up rancidification. As such, always ensure your jar is airtightly sealed all the time. This way, you prevent air from getting in, mold development, and pantry bug contamination. If you’re not suing jars, resealable Ziploc bags are also great.

Aluminum Foil

Aluminum foil can also come in handy in preventing mold formation. Line your storage container with aluminum foil before pouring in chia seeds. Remember to cover the seeds with foil from above after pouring. This will keep the chia seeds safe from moisture, prolonging their shelf life.

Avoid Scooping Seeds

Pouring chia seeds directly into your bowl or cooking pot is better than scooping. When you scoop the seeds using a spoon, you may transfer food leftovers or dust from the spoon to the seed’s jar, contaminating them. So, always pour chia seeds into a spoon, cooking pot, bowl, or measuring cup instead of dipping utensils in the storage container.


Examining the chia seeds now and then is crucial, even if they are within the shelf life. Crush 2 to 3 tablespoons of the seeds using a mortar and pestle and examine spoilage indicators. If the seeds show signs of rancidity, freeze them right away to prolong their shelf life further.
