Freeze dried food can be stored for up to 25 years! Its longevity depends on how you store it, however. Here are some tips for properly storing freeze dried food so they’re fresh and ready when you need them:

Make Sure It’s Dry

When you remove your food from the freeze dryer, break a large piece of the food in half and check for ice particles in the very center of the food or touch your tongue to it to make sure it’s not still cold. It it’s not, it’s dry. Freeze drying works from the outside of the food to the inside, if your food still has ice particles or is cold in that center portion, you can put it back in the freeze dryer for a short dry cycle. Don’t worry, though, because the freeze dryer makes it simple and will ask you if you’d like more dry time.

Seal it

Place freeze dried food in an airtight container. Otherwise, it will begin to reabsorb moisture from the air and spoil.

  • For a 25-year shelf life, Mylar bags are the easiest and least expensive option. Add an oxygen absorber to make sure oxygen isn’t in your bag and will destroy your food over time. Then, simply seal the bag with an impulse sealer or even just a hot iron or flat iron.
  • #10 cans are also a great way to store long-term food storage, but they do require an investment in a can sealer.
  • Vacuum sealed plastic bags are another good option for all foods except meats or other high-protein foods. For food you want to eat in the near future, resealable jars or containers are just fine. Make sure to add an oxygen absorber to any meats or long-term food storage.
  • Simple air tight jars like the one below work well for snacks such as fruits, vegetables, yogurt, or even cheesecake and ice cream. These can easily store in a pantry for a few months without adding an oxygen absorber. Just remember to seal the jar tight after you grab your goodies.
