How long do chia seeds last? In the pantry, in water, or in the fridge?

If you have purchased a bottle of chia seeds or you purchase in bulk like we do, you might wonder, how long do chia seeds last?  Also, once you open a bottle, it usually takes a long time to eat them, especially if you buy one of the larger bottles.  At times we have had unopened as well as opened chia seeds in the pantry for quite a while.  Eventually I would wonder, are they still going to be good and stay fresh for long?

We’ll jump into how long chia seeds last in this article, and more.

Do Chia Seeds Go Bad?

Chia seeds are just like any nut or seed, and contain oils, which give the seeds or nuts their fat content.  But these are healthy oils that are actually good for us and help our cholesterol.

Oils on nuts and seeds can eventually oxidize with the air and turn rancid.  This doesn’t mean that you will necessarily get sick from eating them, but they will probably lose a lot of their nutritional potency.

But the thing about chia seeds is that they have a lot more antioxidants than most nuts or seeds.  These antioxidants help to preserve the chia seeds from oxidation and keep them fresh for much longer.

That means, while some seeds like poppy seeds might only last well for six months or so, chia seeds can last much longer.

Chia seeds have a lot more antioxidants than most seeds and will last much longer before losing their nutritional content.

How Do You Know if Chia Seeds Have Gone Bad?

Chia seeds last for a long time.  So you might never get to the point that they go bad.  I’ve bought chia seeds in bulk before and surprisingly they have lasted for quite a long time with no noticeable changes.

But eventually, if they do go bad, or rancid, they will probably have a bitter flavor and smell.  Remember, naturally chia seeds have basically no taste or smell.  So if they start to have a certain taste or a bitter taste, then maybe they have started to go rancid.

But this doesn’t necessarily mean they will make you sick.  Unless the taste or smell is extremely strong or unpleasant, meaning something drastic probably happened to them, then really when they go rancid it just means that they won’t have the same nutritional value.  They won’t be as good for you as when they were fresh.

But if in doubt, or they have a strong or bad flavor, then throw them out.  Also, if they grow any kind of mold, then throw them away.  This would probably happen if they got wet somehow.

If chia seeds go bad or rancid, they might begin to have a bitter taste to them.  Chia seeds last for a long time so this probably won’t happen for quite some time.

How Long Do Chia Seeds Last in the Pantry?

If you are wondering how long do chia seeds stay good in their raw form last, unrefrigerated, here’s the answer.  Chia seeds are fairly tough, and can last for quite a long time, even without being refrigerated.

The chia seeds that we buy, usually have a shelf life expiration date that is two years or more from the time we buy them.  Of course, I don’t know how long they may have already been sitting there, that’s not possible to know.  But, I’ve read that the life of chia seeds can be up to 3-4 years on the shelf or in the pantry.  So, we will say that the shelf life is anywhere from 2-3 years.

Also, like most food products, expiration dates are usually set at a fairly conservative number.  This means that you probably don’t have to throw chia seeds away right after they pass the expiration date on the container.

Chia seeds can last on the shelf from anywhere from 2-3 years, and possibly longer.

Also, make sure that they are stored the proper way, preferably in a pantry or area that is not too warm or cold, and also keeps them away from the light.

But with that being said, like most foods that begin to degrade over time, it’s probably best to eat them as soon as you can.  Not that you have to force yourself to eat tons of them super-fast, afraid that they will go bad.  But, do realize when buying them, it’s probably better to have fresher chia seeds than ones that have been sitting in the pantry for years.  After this amount of time, they may not be as fresh.

But, since chia seeds do last for quite a long time, you can rest assured that they will stay fairly fresh, even after sitting for long periods of time in the pantry.  The biggest concern is that they will probably lose their nutritional value.  I think that even over the 3-year mark, chia seeds probably don’t really go bad in the sense of spoilage, they will probably just lose some nutritional value.

Also, as a note, organic chia seeds will last the same amount of time as non-organic chia seeds.
