Freeze dried flowers are

What are freeze dried flowers and how are sublimated flowers different from stabilized flowers and dried flowers?
Sublimation or lyophilization (a more professional term is very gentle drying of products, preservation by dehydration, at very low temperatures. From a deep frozen state, the product turns into a dry one, bypassing the liquid state, such drying takes place in a vacuum at minus temperatures!
At the same time, not only all substances are stored in the product, trace elements and flora, but also the integrity of cells and peptide bonds.
Dried in this way (lyophilized) product, retains all the properties of fresh, live product, and under certain conditions, example, during rehydration, can completely restore all properties and form of the original, fresh product.
Complex and expensive equipment is used to dry sublimation flowers and plants – freeze dryers.
Example, it is the edible sublimated flowers and their petals that will preserve not only all the trace elements and vitamins of the plant, ay 100% taste properties. Edible freeze-dried flowers are used in pharmaceuticals, confectionery industry and cooking.

Certainly, sublimation (or lyophilization) it is the most expensive type of drying on Earth!
Especially valuable products and substances are usually subjected to freeze drying, where you need to save all these properties and components, such as drugs and enzymes, blood. Currently, freeze-dried fruits are also very popular, vegetables and meat.
Example, the first lyophilized commercial product was sublimated coffee back in the 19th century.

Sublimated (or lyophilized) flowers remain conditionally alive, they are preserved by lyophilization, their cells remained intact, and tissues are biologically alive. Even if through 50 years to water such sublimated flowers with water (to rehydrate) they will again acquire the form and some properties of living plants. So, if a bouquet of sublimated flowers is placed in a vase with water, they will come to life again and take shape, natural freshness and aroma of freshly cut flowers.

Unlike sublimated flowers – stabilized flowers and dried flowers – cannot be revived, their shelf life is limited.

Stabilized flowers – chemically processed, usually glycerin, which allows them to keep their appearance and rich colors for several years, such flowers lose their smell and cannot be called natural. Not all flowers are suitable for stabilization.
Dried flowers – dried with warm air, they are also completely natural plants, they are able to retain their natural appearance for some time, color, and sometimes the aroma.

The uniqueness and philosophy of lyophilized products (sublimated) flowers – an opportunity to breathe life into them, will revive the memories associated with such a bouquet, even through 50 years!
