There is a large number of various kinds and varieties of this drink, but only sublimated coffee is the closest to natural, and therefore is more popular than conventional soluble.
Feature of manufacturing technology
What is the difference between freeze-dried coffee and simple soluble coffee? Manufacturing technology. The coffee mass is first boiled, then the essential oils are separated, and then frozen. Dry granules are enriched with essential oils, subjected to the aromatization process and packed into containers. It is believed that the sublimated product is more useful than the usual soluble, since unlike the latter it is not compressed under high pressure, accompanied by the destruction of molecules and the loss of most of the nutrients.
Useful and harmful properties
The benefits and disadvantages of soluble freeze-dried coffee are quite equivalent. Of the positive qualities can be noted improvement of blood circulation, stimulation of brain activity, struggle with drowsiness and headache.

Coffee removes calcium from the body, so fans of this drink should take care of the use of foods rich in this mineral. Contraindicated in persons with diseases of the digestive tract, heart and blood vessels.
