Which Foods Can Really Last 25 Years or More?
A few carefully selected dry foods can remain usable for decades—but only with the right moisture level, packaging, temperature, and storage history. Here is what belongs in a 25-year plan, what does not, and how to build a food reserve you can actually use.

“Shelf life” is often used as if it were a single expiration clock. It is not. Food safety, nutritional value, flavor, texture, package integrity, and cooking performance can decline at different rates. A dry staple may still provide calories after decades while taking longer to cook or tasting less fresh.
This is why a realistic food plan should separate everyday pantry rotation, ready-to-eat emergency meals, and deep-storage staples. Expecting one food to perform all three jobs usually leads to waste.
What food dates actually mean
For most food sold in the United States, a date such as “Best if Used By” indicates expected peak quality rather than an automatic safety cutoff. The federal exception is infant formula, which should not be used after its “Use By” date. Product-specific handling instructions and recalls still matter.
- Best if Used By/Before: generally indicates when flavor or quality is expected to be best.
- Sell By: helps retailers manage inventory and display time.
- Use By: generally reflects the manufacturer’s recommended period for peak quality; for infant formula, it must be followed.
- Pack or production date: identifies when the item was produced and can help you calculate age and rotate stock.
A date does not rescue food that was stored badly, and a pleasant smell does not prove that food is safe. Some hazards cannot be seen, smelled, or tasted. Use the label, storage history, packaging condition, official recalls, and product instructions together.
Long-term food-storage comparison
| Food | Can reach 25+ years? | What must be true | Main limitation |
|---|---|---|---|
| White rice | Very dry, oxygen-controlled packaging, cool storage | Brown rice does not store nearly as long | |
| Wheat berries | Whole intact kernels, dry and sealed | Requires a grain mill or suitable recipes | |
| Dried beans | Low moisture, oxygen removed, intact package | Older beans may require longer cooking | |
| Rolled oats | Proper long-term packaging and cool storage | Not the same as flavored instant oatmeal | |
| Dry pasta or macaroni | Plain, low-fat pasta protected from moisture and pests | Egg-rich or whole-grain pasta may age faster | |
| Potato flakes | Commercially dried and oxygen-controlled | Check additives and manufacturer packaging | |
| Dried apple slices | Very low moisture and long-term packaging | Ordinary soft dried fruit is not equivalent | |
| Commercial freeze-dried foods | Factory-sealed product with a stated 25–30-year life | Usually needs clean water; opened life is much shorter | |
| Sugar, salt, and honey | Protected from contamination and moisture | Not balanced foods; texture can change | |
| Commercial canned food | No—not a sound 25-year plan | Rotate by the label and can condition | USDA quality guidance is generally 1–5 years |
| MREs | No | Follow the maker’s time-and-temperature guidance | Heat dramatically shortens storage life |
| Nuts, ramen, brown rice, ghee | No | Rotate normally | Fat oxidizes and becomes rancid |
Foods that can belong in a 25-year storage plan
The estimates below are not promises for repackaged food in every home. They describe foods that have supporting research, suitable chemistry, or a product-specific manufacturer rating when stored under controlled conditions.
White rice
White rice is one of the strongest low-cost candidates for deep storage. Research on residentially stored white rice found acceptable sensory and nutritional quality after storage periods extending to 30 years.
Do not substitute brown rice: its natural oils shorten its storage life significantly.
Hard wheat berries
Whole wheat kernels store better than whole-wheat flour because less surface area is exposed and the grain has not been milled. Properly packaged wheat has performed well after 30 years, but households need a grain mill or recipes that use intact wheat.
Store wheat—not ordinary bags of flour—when decades are the goal.
Dried pinto and other low-fat beans
Utah State University reports that beans packed in #10 cans or Mylar-type bags with oxygen removed can last 10 years or more, while BYU testing found 30-year-old pinto beans still acceptable to most emergency-use taste-panel participants.
Beans generally become harder with age and may need soaking, more fuel, or pressure cooking.
Rolled oats
Properly packaged rolled oats have remained acceptable in long-term testing for periods approaching 30 years. Plain oats are a better deep-storage choice than flavored packets containing dairy, fruit pieces, or added fats.
Packaging and processing style matter; use the product’s specific storage guidance.
Plain dry pasta
Low-fat, low-moisture macaroni or pasta can perform well in long-term packaging. Choose plain refined-grain pasta for deep storage and keep whole-grain, fresh, filled, or egg-heavy products in normal pantry rotation.
Pasta still requires water and fuel, so include both in the plan.
Dehydrated potato flakes
Plain commercial potato flakes have also remained acceptable in multi-decade storage research. They prepare faster than whole dried beans or wheat and can reduce cooking-fuel demand.
Products containing butter, cheese, or other fatty ingredients may have different shelf lives.
Very dry apple slices
Properly dehydrated and packaged apple slices have performed well in long-term research. This does not mean that a soft, chewy bag of grocery-store dried fruit will last 25 years; moisture content and package design are decisive.
For a decades-long claim, use a product packaged and labeled for that purpose.
Commercial freeze-dried meals
Some unopened, factory-sealed freeze-dried foods carry manufacturer shelf-life ratings of 25 or 30 years. Follow the exact product label rather than assuming every freeze-dried item has the same lifespan.
Most require clean water, and the useful life after opening can be measured in days, weeks, or months—not decades.
Freeze-dried fruits and vegetables
Low-moisture produce packed commercially with a stated long-term shelf life can add variety, color, and nutrients that a grain-and-bean reserve lacks. Verify the label because fat content and residual moisture vary by ingredient.
Home-dehydrated and commercial freeze-dried foods are not interchangeable.
White sugar
Granulated sugar resists microbial spoilage when kept dry and uncontaminated. It may harden into a block without becoming unusable. Because oxygen absorbers can worsen caking, follow packaging guidance intended for sugar.
Sugar supplies calories and cooking utility, but it is not a balanced emergency food.
Salt
Pure salt is mineral rather than a perishable food and can remain usable indefinitely if protected from moisture and contamination. Iodized salt may lose iodine quality over time even though the salt itself remains useful.
Store according to the type and intended use; do not treat salt as a calorie source.
Honey
Honey’s low available moisture and acidity make it exceptionally stable when sealed and uncontaminated. Crystallization is a normal physical change and does not by itself mean the honey has spoiled.
Never give honey to a child younger than 12 months because of infant botulism risk.
Foods commonly—and incorrectly—called 25-year foods
How to store food for decades
- Begin with the right food. Choose dry, low-fat staples or a factory-sealed product carrying a clear long-term shelf-life statement.
- Control moisture. Only sufficiently dry foods belong in oxygen-reduced dry storage. Do not apply a dry-food method to moist foods.
- Use appropriate food-contact packaging. Common systems include sealed #10 cans or high-barrier Mylar-type bags placed inside food-grade buckets for physical protection.
- Use the correct oxygen absorber. Match it to the container and food, follow the supplier’s directions, and do not improvise with foods that are not dry enough.
- Keep storage cool and stable. Heat accelerates quality loss. Avoid attics, vehicles, sheds, damp basements, and locations beside furnaces or water heaters.
- Label everything. Record the food, package date, lot or product date, preparation instructions, allergens, and expected review or rotation date.
- Inspect without repeatedly opening. Check for punctures, broken seals, moisture, rust, insects, rodents, swelling, or other damage.
- Keep a working pantry too. Deep storage does not replace foods you can eat without large amounts of water, fuel, or preparation.
When to discard stored food
Discard food with a broken seal, leaking or swollen packaging, evidence of moisture or pests, mold, unexplained discoloration, or an abnormal odor. Deeply dented cans—especially at seams—and cans with severe rust or bulging should be discarded. Never taste questionable food to determine whether it is safe.
For commercially packaged products, also check recalls and follow the manufacturer’s directions. When the storage history is unknown or the package has been compromised, replacement is less costly than a foodborne illness.
MREs are useful—but they are not 25-year food
The old version of this article claimed that MREs could last 25–30 years. That is not an appropriate planning assumption. MRE STAR currently states that its complete meals can last up to five years when stored at 70°F or cooler, with higher temperatures shortening expected life.
MREs fill a different and valuable role: their entrées are fully cooked, require no refrigeration before opening, and can be eaten without a conventional kitchen. MRE STAR M-018H cases also include a flameless heater with every complete meal. That makes MREs useful for outages, evacuation, travel, and the ready-to-eat layer of a diversified food supply.
Build a layered food supply—not a 25-year time capsule
A strong household reserve normally combines several layers:
- Everyday pantry foods that you routinely eat and replace.
- Canned and ready-to-eat foods for periods with limited water, fuel, or cooking capability.
- MREs or other complete meals for maximum convenience during outages and evacuation.
- Long-term dry staples for affordable calories and bulk nutrition.
- Commercial freeze-dried foods for long storage, low weight, and meal variety.
- Stored water and cooking capacity sized to the foods you selected.

Frequently asked questions
Can ordinary grocery-store rice last 25 years?
Not in its original thin bag. White rice can be a decades-long staple when it begins dry and is sealed in appropriate oxygen-controlled packaging, protected from pests, and stored cool. Brown rice is not a substitute because its oils shorten storage life.
Can I vacuum-seal any food to make it last 25 years?
No. Vacuum sealing does not remove all oxygen, correct excess moisture, stop fat oxidation, or make an unsafe food suitable for room-temperature storage. Use methods developed for the specific food.
Do oxygen absorbers make food safe indefinitely?
No. They are one component of a dry-food packaging system. Food moisture, absorber size, package barrier, seal quality, temperature, and pests all affect the result. Oxygen-reduced storage should not be improvised with moist food.
Do canned foods last 25 years?
Commercial cans can sometimes remain intact beyond their quality dates, but a 25-year canned-food plan is not supported by ordinary USDA storage guidance. Rotate high-acid cans more frequently and low-acid cans within their normal multi-year pantry window.
Are MREs better than freeze-dried food?
They solve different problems. MREs can be eaten immediately and do not require rehydrating the entrée, while freeze-dried foods are lighter and may carry much longer unopened shelf-life ratings. Many households benefit from keeping both.
Does honey really last forever?
Properly sealed honey is exceptionally stable, but “forever” is not a guarantee for every jar. Contamination, added moisture, package failure, and poor handling can still create problems. Crystallization by itself is normal.
How often should I inspect long-term food storage?
Inspect the storage area and exterior packaging at least once or twice a year, and after flooding, pest activity, extreme heat, or physical damage. Keep an inventory so old and short-lived items are rotated first.
