The invention comprises of an implementation of the lyophilization process in a method for a large-scale preservation of the entire biological material prior to the extraction and/or the utilization/manipulation of any substances of the biological content. The drying-conservation of all the natural substances is achieved via deep-freezing evaporation followed by complete drying of the biological material by the means of sublimation, and other additional manipulations and procedures suitable for the preparation of various commercially viable products further on.
