Freeze-drying is said to be the biggest thing in the food business since the sliced bread. Thanks to the process of freezing and sublimation of water from the products, the shelf life of freeze-dried foods can be significantly extended, which means less waste.
People often take packs of freeze-dried porridge and soups on hikes and long expeditions, as they are very nutritious, well stored, and take up little space. For the same reasons, astronauts can enjoy freeze-dried foods in orbit.
Let’s see what other neat facts we can find out about this miracle technology!
1. What is freeze-drying?
As we’ve already said, freeze-drying is one of the methods of food conservation. By removing moisture from fresh food, using vacuum, we can reduce the mass of the final product by five to ten times, while at the same time, preserving all the beneficial properties and taste qualities.
2. What products can be freeze-dried?
Aside from the obvious meats, fish, fruits, porridge, and soups, you can very successfully freeze-dry vegetables, dairy products, confectionery, mushrooms, and all kinds of seasoning.
3. What should you do before eating freeze-dried food?
Rehydrating your snacks is important. Open the pack and put the contents in water. After a few minutes, it will return to its previous size. Always check the package for how much liquid is required.
