NMR-spin echo and dielectric studies of water in biopolymers have been carried out. According to the data on the relationship between the time of spin-spin relaxation, the energy of movement activation and electroconductivity, and moisture-bearing it can be concluded that water sorption on biopolymers of the type of gelatin, starch, cellulose up to a certain humidity value takes place in a vacuum. With an increase of moisture-bearing the process of sorption may be presented as a solution of low-molecular substance in a high-molecular one.
