Vacuum Sealing Dehydrated Food in Mylar

To preserve dehydrated food, Mylar is a much more economical choice than canning jars and can have the atmosphere evacuate easier. The downside is Mylar bags are one use, but small bags can hold individual portions. If you have a number 10 can, you can divide it up into vacuum sealed individual portions to greatly lengthen its once-opened shelf life.

You will need an iron, a flat metal bar (I used a level) a vacuum, Mylar bags and the food to be packaged.

I'm using Mylar bags I ordered off Amazon. Put as much food as you will need at one time in the bag and shake down.

My bags arrived with a package of O2 absorbers. Even though I will vacuum out most of the atmosphere, I used them also.

I seal the bags as far across as I can and still have space for the crevice tool of the vacuum to fit. The iron is on a medium high setting and the metal under it has a notch running the length that allows for two seals at once.

Insert the crevice tool into the opening you left. Turn on the vacuum until the Mylar sucks tight to the food.

Then, at an angle to the first seal and leaving the vacuum on, make another seal that crosses the first.

This way, I have two seals crossing two other seals with most of the air evacuated and an absorber inside. All that is left to do is label the food for use and store.
