Simulation for Molecular Weight Distribution of Chitosan after Degradation by Papain (Ⅱ) ——Validatingt heA rithmeticR eliability

Abstract

Abstract: In order to testify the effect and reliability of“ simplified-reverted” simulation method, the molecular weight distribution (MWD) of several chitosan samples with different degree of deacetylation (DD) after degradation was measured by gel-permeation chromatography(GPC), and the MWD of the same samples was simulated by“ simplified-reverted” method. It was shown that the method mentioned above could effectively predict the trend of MWD of the enzymatic degradation products of chitosan. The method could be employed as the predictive approach and the basis of optimal control on the MWD of chitosan after degradation by papain.

Key words: chitosan, degradation, molecular weight distribution, simulation, validation
