How to freeze dry raspberries
A typical batch of raspberries runs about 28 hours in a home freeze dryer, plus about 3 hours of extra dry time. Plan on about 12 months (1 year) of good quality for freeze-dried raspberries, as long as the food is fully dry, sealed in an airtight container or mylar bag with an oxygen absorber and stored cool and dark. These are typical estimates from the FreezeLog guide, not exact times or a safety limit.
General guidance only. Follow your freeze dryer manufacturer's instructions and current food-safety guidance. These are rough figures, not a promise that any food is safe to store or eat. Actual results depend on your machine, load, packing and storage.

How do you prep raspberries for freeze drying?
Rinse gently and pat dry. Halve large berries if you can.
How do you load raspberries on the trays?
Place in one layer. They are delicate, so avoid stacking.
How long does it take to freeze dry raspberries?
A typical batch of raspberries runs about 28 hours in a home freeze dryer, plus about 3 hours of extra dry time. Your machine and load will differ, so check that the batch is dry before you pack it. Here is how to tell when a batch is done.
How do you store freeze-dried raspberries?
Once the pieces snap crisply with no cold or soft spots, pack them quickly. For long-term storage, seal them in a mylar bag or a jar with an oxygen absorber. A jar without an absorber is short term, for food you will eat within about a month. Keep it cool and dark and open it as rarely as you can.
What is the shelf life of freeze-dried raspberries?
Plan on about 12 months (1 year) of good quality for freeze-dried raspberries, as long as the food is fully dry, sealed in an airtight container or mylar bag with an oxygen absorber and stored cool and dark. That is an estimate of quality, not a safety limit.
How do you eat or rehydrate freeze-dried raspberries?
Eat dry or crumble over yogurt and cereal. They break down quickly if soaked.
