Study on the Reduction of Lipid Peroxidization by Chitosan

Abstract:

The in vitro and in vivo effect of chitosan on the reduction of lipid peroxidization was studied in this manuscript.The results showed that chitosan at an addition of 0.02%had antioxidation effect on the lard and crude rape oil,but the activity was worse than that of ascorbic acid.0.05%chitosan and ascorbic acid exhibited the similar activity on the lipid peroxidization. And the chitosan significantly reduced the concentrations of serum free fatty acid and Malondialdehyde and but increased the activities of superoxide dismutase,catalase and glutathione peroxidase.Those results demonstated that chitosan decreased the lipid peroxidization through regulating the anti-oxidation enzyme activities.
