What food can never expire?

When it comes to food, most items have a definite shelf life and expiration date. However, certain foods may last indefinitely without spoiling under the right storage conditions. Though no food literally lasts forever, some come pretty close if stored properly.

Honey

Honey is one of the few foods that does not spoil. In fact, archeologists have found pots of honey thousands of years old that are still edible! This is because honey is low in moisture and acidic, which prevents microbes from growing. As long as it is properly sealed, honey can last indefinitely at room temperature without going bad. Pure honey will crystallize over time, but this process does not affect the safety or quality of the honey. Simply place the jar in warm water to reliquefy crystallized honey before use.

Why Doesn’t Honey Spoil?

There are a few key reasons why honey doesn’t spoil:

  • Low moisture content – Microbes need sufficient water activity to grow, but honey contains very little moisture.
  • Acidity – The average pH of honey is around 3.9, which is low enough to inhibit the growth of most microbes.
  • Hydrogen peroxide – Honey contains an enzyme that produces hydrogen peroxide, which has antimicrobial properties.

As long as it remains properly sealed in an airtight container, honey will never go bad due to its natural properties.

White Rice

White rice is another food that has an indefinite shelf life. When stored properly in an airtight container in a cool, dry place, white rice can last forever. The low moisture content and lack of fat in white rice prevents it from going rancid over time. Additionally, the milling process to make white rice removes the oils from the bran and germ, which grants white rice a longer shelf life than brown rice.

Maximizing White Rice’s Shelf Life

Follow these tips to extend the shelf life of white rice indefinitely:

  • Store rice in an airtight container in a cool, dry place.
  • Keep rice away from light, heat, and moisture.
  • Freeze rice for even longer freshness.
  • Add a desiccant packet to absorb any moisture.
  • Store rice with an oxygen absorber to prevent oxidation.

As long as white rice is kept dry and sealed from air, it will stay fresh at room temperature without spoiling.

Soy Sauce

With its high sodium content, soy sauce can essentially last forever when unopened. The high salt concentration prevents microbial growth and slows down enzymatic reactions. As long as it remains sealed, soy sauce has no risk of spoilage. An unopened bottle of soy sauce can be safely stored at room temperature for years without ever going bad.

Maximizing Opened Soy Sauce’s Shelf Life

Once opened, soy sauce has a slightly shorter shelf life but can still last up to 3 years when stored properly. Follow these guidelines for maximizing opened soy sauce’s shelf life:

  • Transfer soy sauce to a sealable container and exclude as much air as possible.
  • Refrigerate after opening – this slows chemical reactions.
  • Check for signs of spoilage like mold, changes in color or texture.
  • Use clean and dry utensils when dispensing soy sauce.

With proper storage and handling, an opened bottle of soy sauce can still maintain quality and safety for several years.

Sugar

Sugar is extraordinarily stable and resists spoilage due to its low moisture content and lack of proteins. Provided it is stored in an airtight container in a cool, dry place, sugar can last forever without expiring or deteriorating in quality. The high solute concentration prevents microbial growth, while the stable chemical structure of sucrose prevents chemical degradation. Granulated white sugar has an indefinite shelf life.

Storing Sugar for Maximum Freshness

Follow these guidelines to extend sugar’s shelf life:

  • Store in an airtight container – this prevents moisture absorption.
  • Keep sugar in a cool, dark cupboard or pantry.
  • Avoid temperature fluctuations which can cause condensation.
  • Use clean and dry scoops when dispensing to avoid contamination.
  • You can also freeze sugar for even longer freshness.

When kept dry and sealed away from contaminants, sugar will remain fresh and safe to eat indefinitely.

Salt

Salt is inherently shelf-stable and does not require refrigeration. Due to its high solute concentration and lack of organic material, salt can last indefinitely without spoiling. Table salt’s chemistry is very stable and not conducive to microbial growth. Salt may eventually clump together due to moisture absorption but it is still perfectly safe to eat.

Storing Salt Correctly

Salt’s shelf life can be extended by taking these storage precautions:

  • Keep salt in an airtight container to prevent clumping from humidity.
  • Store in a cool, dry place away from heat sources.
  • Use a clean, dry scoop when dispensing to avoid contamination.
  • Keep plain salt away from salt blends which may contain ingredients that can spoil.

With proper dry storage, salt can be kept at room temperature forever without spoiling or losing quality.

Pure Maple Syrup

Due to its high sugar concentration and acidic pH, pure maple syrup is another food that can have an indefinite shelf life when stored correctly. Unopened, pure maple syrup will stay fresh and edible while sealed in the refrigerator or freezer. Once opened, maple syrup can last 3 years refrigerated and up to a year frozen.

Maintaining Maple Syrup Quality

Follow these guidelines when storing maple syrup:

  • Refrigerate after opening – cold temperatures slow microbial growth.
  • Check for mold or fermentation, which signals spoilage.
  • Avoid temperature fluctuations – store in refrigerator not door.
  • Freeze for even longer freshness.
  • Keep container clean and tightly sealed.

With an unopened shelf life of years and an opened shelf life of about 1 year refrigerated, pure maple syrup can essentially last forever with proper storage.

Dried Beans

Thanks to their hard outer shell and low moisture content, dried beans can be stored indefinitely if kept dry and sealed. The dry outer coating protects the beans from oxidation reactions, while the arid conditions prevent microbial growth. Kept in an airtight container in a cool pantry, dried beans will remain edible forever though their texture may harden over time.

Maximizing Dried Beans’ Shelf Life

Follow these precautions when storing dried beans long-term:

  • Store beans in airtight, opaque containers in a cool, dry place.
  • Add an oxygen absorber packet to prevent oxidation.
  • Routinely check beans for visible signs of spoilage like mold.
  • Avoid temperature fluctuations – do not refrigerate.
  • Freeze for even longer freshness.

With the proper dry, sealed storage, dried beans can maintain quality and freshness indefinitely.

Vinegar

Because of its acidic nature and antimicrobial properties, distilled white vinegar has an indefinite shelf life if left sealed. Unopened white vinegar can remain stable at room temperature essentially forever. Once opened, distilled white vinegar has a shelf life of about 2 years if stored properly. The acetic acid prevents microbial growth, while refrigeration andtight sealing slows chemical reactions.

Storing Opened Vinegar

Follow these guidelines for maximizing opened vinegar’s shelf life:

  • Transfer vinegar to a sealable bottle with no air.
  • Refrigerate after opening.
  • Never touch mouth of bottle to surfaces to avoid contamination.
  • Watch for signs of spoilage like mold, cloudiness or changes in taste/smell.

With up to a 2 year shelf life refrigerated, distilled vinegar can essentially be stored forever when sealed and refrigerated after opening.

Hard Liquor and Vinegar

Thanks to its distillation process and high alcohol content, spirits like vodka, rum, whiskey, and tequila have an indefinite shelf life. Hard liquors are sterilized and stripped of compounds during distillation that could cause spoilage. As long as liquor is stored sealed in a cool, dark place, it will remain stable indefinitely. Evaporation and oxidation will eventually degrade liquor quality but not make it unsafe.

Maximizing Liquor’s Shelf Life

Follow these tips for optimizing liquor’s shelf life:

  • Store liquor sealed in a cool, dark place away from heat and light.
  • Keep bottles upright to avoid cork drying.
  • Watch for evaporation, sedimentation, or changes in flavor.
  • Avoid temperature fluctuations – do not freeze liquor.
  • Dilute heavily evaporated liquor with distilled water.

With proper storage, hard liquors like vodka, rum, tequila, and whiskey have an indefinite shelf life before lacking quality though not safety.

Cornstarch

Like flour, cornstarch has an indefinite shelf life due to its lack of moisture and stable chemical structure. As long as cornstarch is kept dry in an airtight container, it will remain fresh. Celsius, humidity, and light cause faster starch molecule degradation, so ideal storage conditions are in a cool, dark pantry. But even under less than ideal conditions, cornstarch has a limitless shelf life though quality may eventually decline.

Keeping Cornstarch Fresh

Here are some tips for maintaining cornstarch freshness:

  • Keep cornstarch in an airtight container in a cool, dry place.
  • Avoid exposure to moisture, heat, and light.
  • Store away from odor-producing foods which cornstarch can absorb.
  • Use a clean, dry utensil to scoop cornstarch.
  • Look for clumping or other signs of moisture absorption.

With the right dry, sealed storage, cornstarch can stay fresh and usable indefinitely.

Canola Oil

Like other vegetable oils, canola oil’s stability and shelf life depends largely on storage conditions. When sealed in an airtight container and stored in cool, dark conditions, canola oil has a shelf life of up to 2 years. Refrigeration can even extend its shelf life up to 5 years before going rancid. Canola oil is relatively stable due to its fatty acid profile but will eventually oxidize.

Maximizing Canola Oil’s Shelf Life

Follow these guidelines for optimizing canola oil’s shelf life:

  • Purchase small bottles to limit air exposure after opening.
  • Limit light and oxygen exposure – store in dark, airtight containers.
  • Refrigerate after opening to prolong freshness.
  • Watch for changes in smell or taste which indicate rancidity.
  • Avoid temperature fluctuations.

With up to 5 years refrigerated, canola oil can essentially last indefinitely with proper sealed, temperature-controlled storage.

Raw Cane Sugar

Like white sugar, raw cane sugar has an indefinite shelf life due to its pure sucrose content and lack of moisture. Raw cane sugar retains trace amounts of molasses so it may harden over time, but this does not indicate spoilage. As long as raw cane sugar is kept in an airtight container in a cool, dry place, it will stay fresh and edible indefinitely.

Storing Raw Cane Sugar

Here are some guidelines for maximizing raw cane sugar’s shelf life:

  • Store in an airtight opaque container
  • Keep in a cool, dry place to prevent moisture absorption
  • Avoid temperature fluctuations which can cause condensation
  • Use a clean, dry scoop when dispensing the sugar
  • Check for clumping which signals moisture absorption

With the proper storage precautions, raw cane sugar can be kept indefinitely without spoiling or losing quality.

Conclusion

While no food literally lasts forever, certain pantry staples have an indefinite shelf life when stored under the right conditions. Keeping foods dry, sealed away from air, and stabilizing temperatures are key to maximizing freshness. With minimal moisture, light, air exposure, and contaminants, foods high in sugar or salt content like honey, white rice, pure maple syrup, dried beans, and raw cane sugar can all be safely stored at room temperature indefinitely without spoiling or significant quality loss. Likewise, vinegar, soy sauce, liquor, and oils can have an indefinite shelf life if refrigerated after opening. Following proper storage methods can essentially extend a food’s shelf life indefinitely, making it the next closest thing to “non-perishable.”
