The object of the invention is a method of obtaining the aqueous solution of chitosan and its application in the form of chitosan composition and chitosan aerosol, characterised in that the obtained solution of chemically non-modified microcrystalline chitosan, after neutralization and separation from acidic chitosan solution is replenished with water and then mixed, while during the mixing process the solution is saturated with inorganic acidic oxides, preferably carbon dioxide, until obtaining clear chitosan solution and dissolving chitosan. The object of the invention is also a method of producing chitosan hydrogel membrane characterised in that the aqueous solution of chitosan obtained according to the invention is poured to the mould and then conditioned preferably at a room temperature, under atmospheric pressure conditions. The object of the invention is also a method of producing chitosan-protein biopolymer material characterised in that the aqueous solution of chitosan obtained according to the invention, is mixed with modification additives such as cross-linking compounds, plasticisers, biologically active substances, preserving agents, and then mixed with a dispersion of collagen and/or gelatin, formed, incubated and conditioned according to a known method. Such chitosan-protein biopolymer material can be dried under atmospheric pressure conditions or by lyophilisation, and conditioned according to a known method.
