Let’s get to your question at hand….
What Are Chia Seeds?
Chia seeds are tiny, oval-shaped superfoods that are often compared to poppy seeds or sesame seeds. They come from a plant called Salvia hispanica, which is part of the mint family. This plant has been used for centuries by Native Americans and ancient cultures in Mexico as a food source and also for medicinal purposes. The seeds come in black and white varieties, although they are technically a combination of several mottled colors. Today, chia seeds can be found in many grocery stores or health food stores.
Where Do Chia Seeds Come From?
Evidence suggests that chia seeds were cultivated as early as the 16th century by the Aztecs. The seeds are native to southern and central Mexico. Presently, they are commercially grown in Central and South America.
What Do Chia Seeds Taste Like?
Chia seeds are small, like poppy seeds. When you eat them, you’ll notice they have a subtle yet distinctive nutty flavor.
Are Chia Seeds Hydrophilic?
Yes, chia seeds are hydrophilic. When chia seeds are soaked, they will absorb up to 10-12 times their weight.
Do Chia Seeds Go Bad?
Yes, chia seeds go bad. They contain oil and will eventually turn rancid, rendering them inedible. Fortunately, if stored properly, they last 2 years (and sometimes up to 4 years) before spoiling. Learn how to tell if chia seeds have gone bad.
How To Tell If Chia Seeds Are Expired?
Many companies label their chia seeds with “best by” dates. Often, these dates range anywhere from 18-24 months from the date packaged, but if stored properly, chia seeds last many months or even several years past the “best by” date marked on the package.
If you suspect your chia seeds have gone bad, you should inspect them first using your sight, sense of smell, and touch. If your seeds pass the sight, smell, and touch test, you can taste a few to ensure they are still fresh. Here’s how.
Visually Inspect Your Seeds
- Are there signs of mold? Check to ensure you don’t see any white fuzzy or slimy-looking coating on any seeds. You should also not see any signs of “growth” on your seeds.
- Are your seeds clumping together? When chia seeds go bad, they will start to clump together and cling to the side of their container. If you see your seeds clumping, throw the entire package away.
- Do you see evidence of bugs? If so, toss the bag.
Smell Your Seeds
Due to their oil content, chia seeds can go rancid. Once your seeds have passed the vision test, you need to smell them. If they smell rancid, discard them immediately.
Taste Your Seeds
If your seeds pass the sight and smell test, it’s a good sign they may still be good. At this point, taste a small number of your seeds.
You can crunch on them raw or soak your seeds in water and then taste them. If they have the familiar mild, nutty flavor, you’re good to go. But if they taste “off”, they’ve gone rancid due to their oil content and you should discard them immediately.
Remember, purchasing a new bag of chia seeds is more cost-effective than a trip to your family physician or the hospital.
Pro-Tip: Avoid scooping chia seeds out of the bag. Instead, pour the seeds onto your spoon or into your measuring cup. This helps ensure your seeds don’t get moldy by keeping damp or contaminated items out of your seeds.
Are Expired Chia Seeds Still Good?
As stated previously, many companies label their chia seeds with “best by” dates rather than “use by” or “expiration date. ” They do not tell you exactly when your chia seeds expire.
If your seeds have reached their “best by” date, you should test them as mentioned above before consuming them.
Do Chia Seeds Need To Be Refrigerated After Opening?
No, chia seeds do not need to be refrigerated. However, you can refrigerate them to extend their shelf life.
Be sure to store them in an airtight container to prevent moisture buildup and to prevent the seeds from picking up any “off” odors from your fridge.
You also want to avoid storing them in clear containers to help prevent oxidation of the oils.
What Happens When You Eat Expired Chia Seeds?
In my research, I could find no direct evidence that eating expired chia seeds could make you sick. But we all know eating spoiled foods can make us ill.
As we discussed earlier, most companies use a “best by” date, so while their seeds may be past that date, it doesn’t mean they have actually gone bad.
If your seeds have an off-odor or bitter taste and you feel they have gone bad, do you really want to eat them?
Is getting ill worth the risk? After all, a doctor’s visit will cost you more than replacing questionable chia seeds.
If your seeds have an off smell, a bitter taste, or show any signs of growth, it is best to err on the side of caution and discard the entire container of seeds.
How To Store Chia Seeds
Chia seeds should be stored in a dark, cool, dry place. Think pantry or cabinet away from the sunlight and the heat of your oven.
Once opened, be sure to keep your chia seeds sealed in an airtight container to help extend their shelf life. You can use a freezer bag, airtight storage container, or glass container.
How Long Do Chia Seeds Last In Water
If you choose to soak your chia seeds, they will last up to 5 days in the fridge.
