Microcrystalline chitosan (MCCh) in the form of a gelatinous water dispersion was prepared according to a previously reported
method by which chitosan was regenerated via adding NaOH solution into chitosan solution at constant stirring (Struszczyk, 1987)
The final pH of the dipsersion was 10.0 and the total polymer content amounted to 1% (w/w), including chitosan and gelatin
