What foods can you freeze dry using Freeze Dry Machine ?

Fruits, vegetables, meats, dairy products, meals, desserts, and more. Freeze drying is safe for preserving cooked pasta and grains, unlike canning.

Those of you who follow me on Instagram know that I’ve freeze dried plenty of fruits and veggies, but I also tried some more interesting items like scrambled eggs and fajita filling.

What foods can’t you freeze dry?

Anything that’s mostly fat or mostly sugar will not freeze dry well. Fat won’t dry – but it can heat up and melt in the unit and coat every surface. When I tried pre-cooked pork sausage patties, they made a big mess.

Sugar binds to water, trapping it in the food. This is great for inhibiting bacteria growth, but it means you can’t freeze dry jams and jellies that are mostly sugar. Plain fruit and most desserts are fine.

Can you mix foods in the freeze dry machine ?

Yes, but watch placement. The website claims that flavors don’t mix, but we have found that they do. We ended up with freeze dried kiwis with a hint of green beans. Advice from the freeze drying groups suggests placing stronger flavored items on the upper shelves, milder items on the lower shelves.

As always, proper food safety rules should be observed. Avoid cross contamination, dry thoroughly, and package promptly.

How do I know the food is done freeze drying?

The freeze dryer senses the moisture content of the food and finishes the cycle automatically, but sometimes it’s a little off and you need to add extra time.

When you first remove food from the dryer, it will be a little cool from the ice buildup inside the chamber, but not “cold”. I always break open some larger pieces and check inside for cold spots. If you find cold spots, put the trays back in and add time to the drying cycle. Your freeze dryer will prompt you to check for dryness.
