Non-random chitosans
Process for the preparation of non-random chitosan polymer
Defined pattern of acetylation
Easily degradable in human tissues
Increased biocompatibility and therefore, broad range of applications
Likely better approvable by FDA or other authorities
biomedicine, agriculture, cosmetics and in the food industry
The present invention relates to a process for the preparation of a non-random chitosan polymer, derived by using a deacetylase enzyme in the presence of acetate ions under conditions that allow acetylation of the poly-D-glucosamine by said chitin deacetylase to obtain a chitosan polymer which presents a defined, e.g. blockwise or more regular pattern of acetylation so that e.g. even chitosans with low degree of acetylation are more easily degraded by human enzymes or other advantages can be created compared to chitosans with undefined acetylation patterns.
