<i>IN VITRO</i> DEGRADATION OF PECTIN-CHITOSAN CRYOGELS
The aim of study was to investigate the effect of pectin and chitosan physico-chemical characteristics on the cryogels in vitro degradation time. It was found that cryogels based on Heracleum L. pectin are more resistant to in vitro degradation compared to the cryogel based on apple pectin. The inclusion of chitosan with a high DD into the composition of cryogel increases their degradation time. Thus, by changing the physico-chemical characteristics of polysaccharides it is possible to create biomaterials with controlled degradation time for medical purposes.
