Abstract: The present disclosure relates to a method for extracting chitin nanocrystals through electron beam irradiation comprising the steps of: (i) irradiating a chitin-based solid material with an electron beam; (ii) washing the chitin-based solid material subjected to electron beam irradiation; (iii) adding a basic solution to the washed chitin-based solid material; (iv) high-pressure homogenizing the chitin-based solid material dispersed in an aqueous system to which the basic solution is added, to prepare a suspension containing chitin nanocrystals.

Abstract: The present invention relates to a method for preparing a non-acid-treated eco friendly cellulose nanocrystal and the cellulose nanocrystals prepared by the same. The methods for preparing the non-acid-treated cellulose nanocrystal and extracting the cellulose nanocrystal from cellulosic materials of the present invention are eco-friendly methods, compared with the conventional preparation method for cellulose nanocrystal based on acid-hydrolysis; are efficient due to the total energy saving process; are easy to utilize side products; and are characterized by high yield to produce the target cellulose nanocrystal.
