To provide a preparation process of a chitin decomposition product having an excellent productivity with which a chitin decomposition product can effectively be obtained through an enzyme reaction using, as a base material, a low-crystallinity chitin obtained by lowering the crystallinity of chitin effectively from a chitin-containing material.
This process is for saccharifying a low-crystallinity chitin prepared from a chitin-containing material whose chitin-crystallinity is higher than 35%. The chitin content of the residual content obtained by dehydrating the chitin-containing material is not less than 10 mass%. The water content of the chitin-containing material is 0.01-25 mass%. After a low-crystallinity chitin whose chitin-crystallinity is decreased to not more than 30% is prepared by crushing treatment of the chitin-containing material with a vibration mill or a medium stirring mill, a chitin decomposition enzyme is let to work on the low-crystallinity chitin for saccharification.
