what is freeze dried food

Freeze-dried food has been frozen and dried under reduced pressure so that ice changes directly into vapor. Once properly dried, it is often light and may be eaten dry or rehydrated, depending on the ingredient. Strawberries can add crunch to yogurt; vegetables can become part of a soup.

What does it taste and feel like?

Fruit often has a crisp texture and concentrated flavor. Different ingredients behave differently, so use a small portion first. Add fruit to yogurt just before serving if you want to retain crunch; leave it in a moist dish if you prefer it softer. For vegetables, follow a suitable recipe and adjust liquid gradually.

How should it be stored?

Freeze-dried food absorbs moisture readily. Check that the batch is dry, then pack promptly in a suitable sealed moisture barrier. Label the food, the date and whether it was raw or cooked. Keep it cool and dry. Home shelf life depends on processing, packaging and conditions; there is no universal number for every batch.

FAQ

Can I eat every freeze-dried food without cooking? No. Freeze-drying does not kill illness-causing microorganisms. Foods that require cooking still need safe preparation and cooking after rehydration.

Does it always taste exactly like fresh food? No. The result depends on the ingredient and process. Try a small amount in the dish you intend to make.
