| Abstract: | Objective To study the preparation technology of chitooligosaccharides with degree of polymerization of 6-8. Methods Chitosan was hydrolyzed by special enzymes, then the hydrolysis product was successively ultrafiltered, dried and examined with TLC, HPLC and MALDI-TOF-MS. Results The product was white powder and mainly contains chitooligosaccharides with degree of polymerization of 6-8. Conclusion This method can be used for the preparation of chitooligosaccharides with degree of polymerization of 6-8. |
