Can you eat popcorn that expired 2 years ago?

Quick Answer

It is not recommended to eat popcorn that has been expired for 2 years or longer. Over time, popcorn can develop mold, lose flavor and nutritional value, and become stale or rancid. Most unpopped popcorn has a shelf life of 1-2 years when stored properly. Once popped, leftover popcorn should only be kept for 2-3 days before discarding. Eating very old, expired popcorn could potentially make you sick.

Examining Popcorn Expiration

When considering whether expired popcorn is safe to eat, there are a few factors to take into account:

Types of popcorn

There are two main types of popcorn – microwave popcorn and loose kernel popcorn. Microwave popcorn usually has a shorter shelf life of 6-12 months. The oils and flavoring used in microwave popcorn tend to go rancid faster. Loose popcorn kernels last 1-2 years when stored in an airtight container.

Storage conditions

How the popcorn is stored can greatly impact its freshness and shelf life. Popcorn should be kept in an airtight container or bag. Exposure to air, light, and humidity can cause popcorn to lose its flavor and texture more quickly. Storing popcorn in a cool, dark pantry will help prolong its shelf life. Refrigerating or freezing unpopped kernels can extend the shelf life even further.

Packaging date vs. expiration date

Checking the packaging date rather than relying solely on any expiration date can give you a better idea of the popcorn’s age. For loose kernels, the packaging date indicates when it was packaged. For microwavable bags, the date reflects when the bag was manufactured. Comparing the date to when you purchased and opened the popcorn can tell you how long you’ve really had it.

Signs of stale popcorn

Smelling and inspecting the popcorn can also reveal if it is past its prime. Discard any popcorn that smells musty, rancid or moldy. Kernels that are yellowed or brittle are likely old and stale. Popped popcorn should be discarded at the first sign of staleness, which can occur within 2-3 days. Microwave bags that appear swollen or leaking should also be thrown away.

Risks of Eating Expired Popcorn

Eating expired popcorn comes with potential health risks:

Foodborne illness

One of the biggest dangers is possible foodborne illness from mold growth. Like many grains, popcorn is susceptible to mold if stored incorrectly. Mold can grow unseen inside bags or containers. Consuming moldy popcorn can cause digestive issues or allergic reactions. Some molds even produce mycotoxins that can cause longer-term health effects if ingested.

Rancidity

Over time, the fats in popcorn can become rancid. This causes off-flavors and odors. Rancid popcorn should be discarded, as rancid fats may cause nausea or stomach upset if eaten. The level of rancidity increases past the expiration date.

Nutritional loss

Popcorn’s vitamins, minerals, and antioxidants diminish in potency after the expiration date. So rancid or stale popcorn would not provide the same nutritional value as fresher popcorn. Eating it would provide little benefit.

Choking hazard

Old popcorn kernels are drier and less pliable. During popping, this can cause unpopped kernels to split into hard, sharp fragments that could potentially choke someone eating the expired popcorn. It is safer to discard old unpopped kernels.

How To Tell if Popcorn Is Unfit to Eat

Relying on sight, smell, texture, and taste can help determine if popcorn has gone bad:

Sight

Look for visible mold, especially black or green dots. Check for yellow, brown, or white discoloration. Popped popcorn should not appear soggy or wet. Discard any popcorn with an unappetizing appearance.

Smell

Sniff the popcorn. It should have a pleasant, mild scent. Discard anything with an off, rancid, musty or stale odor. These are signs it could be unfit to eat.

Texture

Stale popcorn kernels feel dried out or brittle. Popped popcorn loses its fluffy, crispy texture as it goes stale. Discard any popcorn with a hard, rubbery, or mushy feel.

Taste

Tasting a small amount can confirm if popcorn tastes rancid or sour. You’ll notice a distinct unpleasant flavor if the popcorn has spoiled. Expired microwave popcorn often tastes bitter or “off” compared to fresh.

Storing Popcorn Properly

To maximize popcorn’s shelf life:

Pantry storage

Keep unpopped popcorn in an airtight container in a cool, dry pantry away from light and heat. Avoid warm or humid spots like above the stove or refrigerator.

Refrigeration

For extended shelf life, store popcorn kernels in the refrigerator or freezer. They will keep for 6-12 months refrigerated or 2-3 years frozen. Allow refrigerated popcorn to reach room temperature before microwaving or air popping.

Microwave popcorn

Leave microwave popcorn in its original packaging. Once opened, reseal the bag tightly or transfer contents to an airtight container for storage. Use within a few months.

Avoid humidity

Humidity causes faster spoilage. Avoid storage in basements, near sinks or showers. Use waterproof containers if storing in the fridge or freezer.

Oxygen absorbers

For bulk loose kernels, using oxygen absorber packets can help extend shelf life. These prevent oxidation that makes popcorn rancid.

Shelf Life of Popcorn

When stored properly, popcorn can stay fresh for the following time periods:

Uncooked popcorn kernels

1-2 years at room temperature
6-12 months refrigerated
2-3 years frozen

Microwave popcorn bags

6-12 months unopened at room temperature
1-2 weeks after opening

Popped popcorn

2-3 days at room temperature
1 week refrigerated in airtight container

Popcorn oil

6-8 months unopened
6 months refrigerated after opening

So popcorn over 2 years old is likely to be expired and of lower quality. For peak freshness and taste, use popcorn within these recommended time frames. Discard any popcorn past its prime.

How to Check Popcorn for Mold

It’s important to inspect popcorn closely for any mold growth before eating. Here are some tips for checking:

Visual inspection

Examine both inside and outside of packaging. Look for black, green, or white dots, spots, or fuzzy growth. Discoloration can also indicate mold. Feel for any lumps or wet spots. If present, assume the product is moldy.

Smell test

Do not eat if you detect a musty, earthy, or stale odor. Even if you cannot see mold, this smell likely means it is present. Do not taste test moldy popcorn.

Microwave test

For microwave bags, open outer packaging and microwave just the inner bag for 10 seconds. This can reveal hidden moisture from mold growth. Do not eat if the test bag appears swollen or leaks.

Small taste test

For loose kernels, cautiously taste a small amount. Never eat more after detecting moldy or rancid flavors. A bitter, musty taste could indicate spoiled popcorn.

When in doubt, throw it out!

If old popcorn shows any signs of mold, moisture, or smelling bad, follow the adage “when in doubt, throw it out.” Mold spores spread rapidly, so moldy popcorn should never be eaten.

Cooking and Reheating Popcorn

Proper preparation and storage after cooking can extend leftover popcorn’s shelf life:

Popping

Always follow package instructions carefully when cooking popcorn. Do not microwave unpopped kernels that are over 2 years old. Old kernels are more likely to create hard fragments.

Portioning

Only pop what you plan to eat in one sitting. Popcorn is best when freshly cooked. Any leftovers should be refrigerated promptly.

Storage containers

Transfer leftover popped popcorn to airtight glass, plastic, or aluminum containers. Do not use plastic bags, as moisture accumulation speeds up staleness.

Reheating

Only reheat popped popcorn once or twice. Reheat in the microwave in short 10-15 second intervals to prevent burning. Do not reheat any popcorn that smells rancid or feels soggy.

Following proper cooking, storage, and reheating methods can prolong popped popcorn freshness an extra 1-2 days. But refrain from eating leftovers more than 3 days old. Cook fresh batches to enjoy popcorn at its best.

Disposing of Expired Popcorn

When tossing old, expired popcorn, consider the following:

Discard bags/boxes

Do not attempt to compost packaging. Place unopened expired microwave bags and popcorn boxes directly in the trash. Avoid ripping open bags to minimize mold exposure.

Empty containers

First empty any leftover loose kernels and dispose of them. Then the containers can be recycled or repurposed if in good condition. Avoid donating very old popcorn containers.

Compost

Stale popcorn and expired unpopped kernels can be added to a compost pile or bin. Ensure other organic materials are present to balance the nitrogen. Do not compost moldy or rancid popcorn.

Trash

If unable to compost, expired popcorn can go in the regular trash. Discard microwave bags unopened whenever possible. Take trash bags out promptly so you don’t smell rancid popcorn inside.

Animal feed

Avoid feeding truly spoiled popcorn to pets or livestock. But very stale popcorn that shows no signs of mold can be used as animal feed in limited amounts if needed.

Be sure to promptly remove expired popcorn from your pantry and discard so it does not contaminate fresh popcorn. Follow safety precautions when handling to avoid illness.

FAQs – Expired Popcorn

Here are answers to some common questions about eating expired popcorn:

Can you eat popcorn a year after the expiration date?

It’s not recommended. 1 year after the printed date, the popcorn is likely to be stale, moldy, or rancid. Eating it could potentially make you sick. Discard any bagged or loose kernel popcorn more than 6-12 months past its packaging date.

What happens if you eat expired popcorn?

Depending on how long ago it expired, eating popcorn past its prime can cause foodborne illness, digestive issues, allergic reactions, or choking. Rancid and moldy popcorn may cause nausea, vomiting, or stomach pains if consumed.

Can expired microwave popcorn make you sick?

Yes, eating microwave popcorn after the date on the package can potentially make you sick. The oils can become rancid and harbor mold more quickly than loose kernels. Discard and do not eat microwavable popcorn bags that are swollen, leaking, or more than 6 months past date.

Can you eat microwave popcorn after the “best by” date?

It’s not recommended. “Best by” dates on microwave popcorn indicate peak freshness and quality. The flavor and texture will progressively decline after the date. Eat within 6-12 months for best taste. Discard bags that are very stale, moldy, or rancid smelling.

What if my popcorn smells bad but doesn’t expire for 6 more months?

Do not eat it! Rancid, musty odors indicate the popcorn has already spoiled. Food can spoil before the expiration date if stored incorrectly. Always rely on your senses. Popcorn that smells or looks bad should be discarded immediately, even if the date hasn’t passed.

Conclusion

Eating popcorn that is 2 years past its expiration date comes with significant health risks and is never recommended. Over time, expired popcorn can develop dangerous molds, become rancid, lose nutrients, and take on unpleasant textures and flavors. To avoid illness, discard any popcorn that is past 1-2 years from its packaging date or shows signs of spoilage like mold, foul odors, or stale texture. With proper airtight storage in a cool pantry or the freezer, most unpopped popcorn lasts 1-2 years. Popped popcorn is only good for 2-3 days. Always inspect and smell popcorn before eating to ensure safety and quality. Following safe food handling practices for storage, reheating, and disposal can help prevent issues with expired popcorn in your pantry.
