How to Store Dehydrated Food for the Long Term
Dehydrated food only keeps for years if it's fully dry and sealed against air. How to condition, package and store it, and what shelf life to expect.
Dehydrating removes the water that microbes need, but stored badly, dried food reabsorbs moisture from the air and spoils. Long-term success is about locking that dryness in.
Step 1: dry it fully, then condition
Food that looks dry can still hold pockets of moisture. Before sealing for the long term, condition it: pack the cooled dried food loosely in a jar, seal it, and shake it once a day for about a week. If you see any condensation on the glass, it isn't dry enough, so dry it more. Conditioning also evens out moisture between drier and wetter pieces.
Step 2: package against air and moisture
Once conditioned, seal it in one of two ways:
- Mylar with an oxygen absorber: the best long-term choice, blocking light, oxygen and moisture.
- Vacuum-sealing: good for shorter-term storage and freezer backup.
Size a correctly rated oxygen absorber to the bag, and get a clean full seal.
Expected shelf life
| Dried food | Sealed, cool storage |
|---|---|
| Vegetables (fully dried) | 5 to 10 yr |
| Fruit | 5 yr, sometimes less |
| Herbs | 1 to 3 yr for flavor |
| Jerky and oily items | Months, not years |
The oily items are the exception again: fat goes rancid regardless of the barrier, so treat dried oily foods as short-term and keep them cool.
Keep it cool and check it
Store sealed dried food cool and dark, and glance at it over time. A bag that has lost its tight, oxygen-free firmness, or shows any moisture or mold, has failed its seal. When judging whether a food is still safe rather than merely good, follow NCHFP guidance.
Dryness is everything: dehydrated food only reaches multi-year storage if it's fully dry and then sealed oxygen-free. Condition it, pack it in mylar with an absorber, keep it cool. Watch oily items, which stay short-lived whatever the packaging.
Frequently asked questions
How do you store dehydrated food long-term?
Dry it thoroughly, condition it (rest it in a jar for about a week to spot any remaining moisture), then package it in mylar with an oxygen absorber, cool and dark. Moisture left behind is what causes spoilage.
What is conditioning dehydrated food?
Resting the dried food in a sealed jar for about a week and checking for condensation or clumping, which reveals uneven moisture. If it sweats, dry it more before long-term packaging, since hidden moisture ruins storage.
How long does dehydrated food last?
Properly dried and sealed against air and moisture, many dehydrated foods keep for years. Freeze-dried keeps longer than air-dried, and low-moisture, low-oil items store best; anything oily or not fully dried keeps less.
