Packaging Freeze-Dried food for Immediate, Short-term, and Long-term Solutions

Proper food packaging is the unsung hero of food preservation. Neglecting the importance of packaging can lead to disappointment and wasted food. To ensure your culinary creations remain fresh and delicious, it's crucial to understand food packaging in three distinct categories: immediate use (up to 12 months), short-term (1-4 years), and long-term (5-25 years). In this comprehensive guide, we'll delve into the best practices for each category, providing you with the knowledge to protect your freeze-dried treasures effectively.

Immediate Use (Up to 12 Months)

Immediate-use packaging is ideal when you plan to enjoy your freeze-dried food within the next few months. While heavy-duty long-term packaging options are available, they are not always necessary for short-term consumption. Here are some recommended packaging solutions:

Best Packaging for Immediate Use (Up to 12 Months):

  • Vacuum Seal Bags with an Oxygen Absorber: Suitable for preserving food for a few weeks to a year.
  • Zip Mylar Bags with Clear Windows: Lasting a few weeks, these bags offer visibility, but they are not as airtight as vacuum seal bags.
  • Ziploc Bags: Perfect for storing food for a few days, they are convenient for short-term use.

Steps to Package Food in a Vacuum Seal Bag for Immediate Use:

  1. Place the freeze-dried food inside the vacuum seal bag.
  2. Add an appropriately sized oxygen absorber (e.g., a 1-quart bag needs a 100cc absorber).
  3. Ensure the area to be sealed is flat and free of debris.
  4. Use a vacuum sealer (e.g., FoodSaver®) to vacuum and seal the bag.
  5. Inspect the seal for folds or missed areas and reseal if necessary.
  6. Label the vacuum seal bag with the date and an item description.
  7. Store it in a plastic container and use it within a year.

Short-term Use (1-4 Years)

Freeze-dried meals and ingredients containing fats are typically suitable for storage between 1 and 5 years but should be consumed within that timeframe. For short-term preservation, two excellent options are glass canning jars and 5-mil Mylar bags. Here's why they are a great choice:

Best Packaging for Short-term Use (1-4 Years):

  • Canning Jars with an Oxygen Absorber: These jars, vacuum-sealed with oxygen absorbers, are ideal for preserving food for 5+ years.
  • 5-mil Mylar Bags with an Oxygen Absorber: While thinner than their long-term counterparts, these bags work well for short-term storage (5+ years).

Steps to Package Food in a Canning Jar with a FoodSaver® for Short-term Storage:

  1. Place the freeze-dried food inside a glass canning jar.
  2. Add an appropriately sized oxygen absorber (e.g., a quart jar needs a 100cc absorber).
  3. Put a lid on the canning jar (use two lids for regular mouth jars during sealing).
  4. Attach the vacuum fitting and remove the air from the jar.
  5. Test the seal with your fingers to ensure it's airtight.
  6. Place a ring on the jar for added security.
  7. Label the jar with the date and an item description.
  8. Store the canning jar on a cool, dark shelf.

Long-term Use (5-25 Years)

For long-term storage that can extend from 5 to 25 years or more, Mylar bags are the most dependable choice. In particular, 7-mil Mylar bags are the standard for long-term preservation. By combining these bags with oxygen absorbers and storing them in plastic totes, you can ensure your food remains of the highest quality throughout the years.

Best Packaging for Long-term Use (5-25+ Years):

  • 7-mil Mylar Bags with an Oxygen Absorber: These thick Mylar bags are suitable for long-term storage, capable of preserving food for up to 30 years.

Steps to Package Food in a Mylar Bag for Long-term Storage:

  1. Place the freeze-dried food inside the Mylar bag.
  2. Add an appropriately sized oxygen absorber (e.g., a 1-gallon bag needs a 300cc absorber).
  3. Gently press to remove any excess air.
  4. Ensure the area to be sealed is flat and clean, and wipe it with a microfiber cloth.
  5. Seal the open end with an impulse sealer.
  6. Inspect the seal for folds or missed areas and reseal if necessary.
  7. Label the bag with the date and an item description.
  8. Store it in a plastic container for added protection.

Mastering the art of food packaging is the key to preserving the flavor, quality, and nutrition of your freeze-dried foods. Whether you're planning for immediate use, short-term enjoyment, or long-term security, selecting the right packaging materials and following the appropriate steps is essential. Mylar bags, canning jars, and vacuum seal bags each have their place in your food preservation toolkit, and understanding when and how to use them ensures your culinary investments will be protected against the ravages of time.
