Once you have processed your food in the freeze-dryer and have packaged it in mylar bags with an oxygen absorber your food is protected from all kinds of issues. If you use common kitchen safety like not mixing uncooked meats with produce it is perfectly safe. I also recommend you label your freeze-dried foods clearly, indicating what is raw and what is cooked.
Hands-down freeze-dried foods, properly stored, last longer than any other preservation method. Most foods can be stored for up to 25 years and will taste just as good as the day you processed them. Your food will also maintain its natural texture, taste, and nutrients.
Because you are using your own foods you control the quality and taste. I love that I can preserve my garden produce and it will taste a look as amazing as the day I processed it. If you make your own meals, you get to control the ingredients and use the recipes your family loves.
I love that I can freeze dry produce, meats, and dairy all with the same machine. The only thing I recommend against freeze-drying is foods with extremely high sugar content or fatty foods. I also recommend only freeze-drying shredded or diced meat (it just seems to rehydrate better).
Using a freeze dryer to preserve your food is hands down the best way to preserve all those wonderful nutrients. Most other preserving methods require heating which is the natural enemy of the vitamins and nutrients in any food. We all know that eating a carrot straight out of the garden is way better for you than eating a boiled carrot. Because you are freezing instead of cooking with a freeze dryer it is the closest thing to fresh-picked!
Another great benefit to getting a freeze dryer for your home is that you can make your own hiking/camping food. Because all of the moisture is removed from your food when you freeze dry your food becomes extremely lightweight. Which of course makes it ideal to carry in a pack. It also can be easily rehydrated with a little boiling water.
Freeze-dried foods should be stored in mylar bags to stay good for up to 25 years. This makes them much lighter and more compact than say home-canned goods. They also don’t take up space in your freezer. We like to keep ours in totes, and you would not believe how many bags I can get in one tote!
I always say if I can learn to use a freeze dryer, anyone can. Once you get a few cycles under your belt, it really is no different than using your oven. Honestly, I feel like it is easier than canning. And if you buy a Harvest Right freeze dryer for your home they have great videos and articles on their website to help you out.
