How To Store Freeze Dried Food for Emergencies and More

Freeze-dried food is a popular choice for emergency preparedness and long-term food storage, thanks to its lengthy shelf life and ease of preparation. Learning how to store freeze dried food correctly is crucial for retaining its quality and nutritional value.

Proper storage techniques can extend the shelf life even further, ensuring that you have reliable sustenance in times of need.

In the following sections, we’ll explore essential tips and tricks for selecting the right containers, using oxygen absorbers and desiccants, and protecting your food supply from pests and contamination.

The Importance of Proper Storage for Freeze-Dried Food

Proper storage is crucial when it comes to maintaining the quality and shelf life of freeze-dried food. When storing freeze-dried food, it is essential to protect it from exposure to light, air, moisture, and extreme temperature fluctuations.

These factors can degrade the food and lead to a loss of flavor, texture, and nutritional value. Additionally, improper storage can cause freeze-dried food to spoil or become contaminated by pests, which poses a risk to your health.

By taking the time to appropriately store your freeze-dried food, you can enjoy its convenience and benefits for years to come.

Selecting the Right Containers

When looking for storage containers, consider using airtight containers, Mylar bags, or vacuum-sealed bags. These options will help keep your freeze-dried food fresh and prevent any outside elements from compromising the taste or quality of the preserved items. Remember, proper storage is key to maintaining the longevity of your freeze-dried food.

Airtight Containers

Airtight containers are a popular choice for storing freeze-dried food, as they keep out air, moisture and harmful contaminants. Look for containers made from food-grade materials, like BPA-free plastic or glass, and ensure they have an airtight seal, such as a screw-on lid or a locking mechanism.

Mylar Bags

Mylar bags are another excellent option for storing freeze-dried food. They provide an extra layer of protection by shielding the contents from light, moisture, and oxygen.

When combined with oxygen absorbers, Mylar bags make a long-lasting, airtight storage solution for your freeze-dried food. To properly use Mylar bags, fill them with the desired food items, add an oxygen absorber, and, finally, heat-seal the bag for a secure closure.

Vacuum-Sealed Bags

Vacuum-sealed bags are another excellent option for storing freeze-dried food. They work by removing air from the bag, which helps to prevent oxidation and maintain the food’s freshness.

Be sure to use food-grade vacuum sealer bags, as these are specifically designed to withstand the vacuum process and protect your freeze-dried items. When sealing, follow the manufacturer’s instructions, ensuring a tight seal to keep the contents fresh and free from moisture.

Using Oxygen Absorbers and Desiccants

To further enhance the longevity of your freeze-dried food, add oxygen absorbers and desiccants to your storage containers. Oxygen absorbers remove excess oxygen, preventing the growth of bacteria and spoilage, while desiccants help maintain an ideal humidity level and keep your food fresh and crisp.

Oxygen Absorbers

Oxygen absorbers are small packets filled with iron powder that, when exposed to air, absorb oxygen and moisture. Including these nifty packets in your freeze-dried food storage containers helps to prevent oxidation and spoilage, maintaining the quality and taste of the food for longer periods.

Make sure to seal the containers immediately after adding the oxygen absorber in order to ensure that only the oxygen within the container is removed.


In addition to oxygen absorbers, you can use desiccants to extend the shelf life of your freeze-dried food. These moisture-absorbing packets help maintain the dry environment necessary for preserving the food’s quality.

Simply slip a desiccant packet into your airtight container, Mylar bag, or vacuum-sealed bag alongside your freeze-dried items. This will help prevent clumping, texture changes, and mold growth caused by excess moisture.

Determining the Shelf Life of Freeze-Dried Food

The shelf life of freeze-dried food can vary depending on factors such as temperature and humidity. To ensure freshness, pay attention to expiration dates and practice proper food rotation. Generally, freeze-dried food can last up to 25 years when stored in ideal conditions.

Temperature and Humidity Factors

Temperature and humidity play key roles in determining the shelf life of freeze-dried food. For optimal preservation, store foods in a cool, dry environment with temperatures between 50 and 70°F (10-20°C) and humidity levels below 60%.

Elevated temperatures and humidity can cause freeze-dried products to spoil faster, so it’s crucial to monitor and maintain these environmental factors to keep your food in tip-top shape.

Expiration Dates and Rotation

It’s important to note the expiration dates on freeze-dried food packaging and practice proper food rotation. Create a system to ensure you consume older items first and consistently replenish with newer ones.

Staying organized and maintaining good inventory records will help you consume your freeze-dried foods within their optimal shelf life, maximizing their taste and nutritional value.

Storing Freeze-Dried Food in a Pantry, Basement, or Garage

Now that you’ve selected the right containers, and taken care of oxygen and humidity, it’s time to find the ideal location for your freeze-dried food storage. A pantry, basement, or garage are popular options, as they typically have low light exposure and stable temperature levels.

The key is to ensure that the area remains dry and cool, with temperatures between 50-70°F (10-21°C), as fluctuations can reduce the shelf life of your food. Humidity levels should be below 60%, to prevent moisture from impacting the quality of the freeze-dried goods.

Finally, ensure that the storage area is clean and organized, so you can easily locate items when needed.

Protecting Freeze-Dried Food from Pests and Contamination

To protect your freeze-dried food from pests and contamination, implement effective pest control methods such as using traps or repellents. Keep your storage area clean and dry to minimize the risk of contamination. Ensure that containers and bags are properly sealed to maintain quality and freshness.

Effective Pest Control Methods

To keep pests away from your freeze-dried food, it’s important to adopt effective pest control methods. Use airtight containers or vacuum-sealed bags to store your food, as these will deter insects and rodents.

You can also use natural deterrents such as peppermint oil or diatomaceous earth near your storage area. Make sure to regularly check your storage area for signs of infestations and address any issues as soon as they arise.

Keeping Your Storage Area Clean and Dry

Maintaining cleanliness is crucial when storing freeze-dried food. Sweep and mop your storage area regularly to eliminate any spills or crumbs that may attract pests. Additionally, ensure there’s proper ventilation and avoid storing directly on the floor to prevent moisture buildup.

Routine checks for potential leaks, pest infestations, and cleanliness will help keep your food safe and prolong its shelf life.

Properly Sealing Containers and Bags

Proper sealing is crucial when storing freeze-dried food. Double-check that airtight containers, Mylar bags, and vacuum-sealed bags are closed tightly to prevent air and moisture from entering.

Additionally, when using Mylar bags or vacuum-sealed bags, ensure they’re sealed with a reliable heat sealer to minimize spoilage risk.


In conclusion, knowing how to store freeze-dried food is essential for maintaining its quality and shelf life.

By selecting the right containers, using oxygen absorbers and desiccants, keeping temperature and humidity in check, and protecting from pests and contamination, you can ensure your freeze-dried food remains delicious and safe to consume whenever you need it.
