Are you a fan of freeze dried food? Whether you’re an outdoor enthusiast, a prepper, or simply someone who appreciates the convenience and long shelf life of freeze dried food, knowing how to store it properly is essential. In this guide, we will provide you with expert tips and step-by-step instructions on how to store freeze dried food to ensure its longevity and quality when you need it most.

How to Store Freeze Dried Food: A Step-by-Step Guide

Step 1: Choosing the Right Containers

Selecting the appropriate containers is crucial for preserving the quality of your freeze dried food. Opt for airtight containers made of materials such as glass, metal, or high-quality plastic. These containers should have tight-fitting lids to prevent moisture and air from entering.

Step 2: Preparing the Freeze Dried Food for Storage

Before storing freeze dried food, ensure it is clean, dry, and free from any moisture. Packaging from reputable brands often comes in sealed pouches, but if you’re transferring food from bulk containers, make sure to use a food-grade moisture barrier bag or Mylar bag to maintain freshness.

Step 3: Properly Sealing the Containers

To ensure long-term storage, it’s crucial to properly seal your containers. Use a vacuum sealer to remove excess air from the packaging before sealing it tightly. Alternatively, you can utilize oxygen absorbers to remove any residual oxygen, further extending the shelf life of your freeze dried food.

Step 4: Determining the Ideal Storage Location

When choosing a storage location for your freeze dried food, consider factors such as temperature, humidity, and exposure to light. Aim for a cool, dry, and dark area. Avoid areas prone to temperature fluctuations, such as attics or garages, as they can degrade the quality of the food over time.

Step 5: Monitoring and Maintaining Storage Conditions

Regularly monitor the storage conditions of your freeze dried food. Check for any signs of moisture, pests, or damage to the containers. It is recommended to keep a record of the storage dates and periodically rotate your stock to ensure you consume the oldest items first.

Factors to Consider When Storing Freeze Dried Food

Temperature and Humidity Control

Freeze dried food is best stored in a cool environment with temperatures ranging between 50°F and 70°F (10°C to 21°C). High temperatures can accelerate the degradation process, while low temperatures may cause moisture to condense and compromise the food’s quality. Additionally, maintaining a humidity level below 15% is crucial to prevent moisture absorption.

Protection from Light and Oxygen Exposure

Exposure to light and oxygen can deteriorate the quality of freeze dried food. Store your containers in a dark area or use opaque containers to prevent light exposure. Implementing oxygen absorbers or vacuum sealing can minimize the amount of oxygen within the packaging, further preserving the food’s taste, texture, and nutritional value.

Pests and Rodent Prevention

To safeguard your freeze dried food from pests and rodents, store it in airtight containers and consider utilizing additional protective measures. Placing bay leaves, diatomaceous earth, or even rodent repellents around the storage area can help deter unwanted critters and protect your precious food supply.
