Sublimation is the transition of a substance from a solid to a gaseous state, bypassing the liquid. The product or the finished dish is subjected to instant freezing at a temperature below minus 100 degrees, and then it is practically completely dehydrated by sublimating ice in a vacuum chamber and receiving sublimated products at the output.
Sublimation, sublimated products Trek’n Eat, packaging, shelf life, cooking features.
Unlike thermal drying, freeze-dried foods retain up to 95% of the nutrients, trace elements and vitamins of the original product, and hence its taste. When water is added to the sublimate, the product is quickly restored and almost in its original form. The sublimation process, as well as the freeze-dried products themselves, were originally developed as part of the space program, but the technology turned out to be so successful that the freeze-dried products soon became available to a wide range of ordinary travelers and hikers..
Sublimated products are lightweight and stored for a long time at any temperature. Well, and that, perhaps, the most important thing is mainly all-natural products that do not contain preservatives, flavor enhancers or some kind of dyes.
