Here’s a little Freeze Drying 101: Oxygen and water are the enemies of freeze dried food.
One of the best ways to preserve food long term is by using Mylar bags with an oxygen absorber to keep oxygen and water from getting into the bag. If you haven’t visited the online Harvest Right Store in a while, check out our new freeze drying accessories. We offer food-grade Mylar bags in two sizes: 8″ x 12″ and a large 10″ x 14″. A pack of 50 is inexpensive and will allow you to store a great deal of freeze dried food.
Tip #1: Oxygen and water are the enemies of freeze dried food
You’ll also want an oxygen absorber for each pouch. Oxygen absorbers protect your freeze dried food from spoilage, mold growth, color change, loss of nutritive values, insect damage and loss of quality. By removing residual oxygen inside packaging to below 0.01% a 300CC oxygen absorber effectively preserves packaged foods without the need for food additives/preservatives and without the need for vacuum sealing.
Tip #2 Waterproof Sharpies are the best way to label your Mylar pouches. No smudging!
To seal the Mylar pouches, you’ll need a heat sealer, also available in our online store.
A 12” impulse sealer will give you a 5mm wide seal, the minimum size required for integrity. Our sealers are easy to use, and don’t have a warm-up time. Members of our online community actually love their impulse sealers and have shared that they’re using them for sealing all kinds of things!
If you’re getting your long-term freeze dried food storage strategy underway, protect your investment with the right storage equipment. Done right, your freeze dried goodies can last up to 25 years!
