| Abstract | ||
| Chitosan prepared from Chitin that extracted from shrimp shell (Penaeus semisulcatus) by removal acetyl group from Chitin by chemical methods, water soluble chitosan derivatives prepared by interaction Chitosan with two types of reducing sugars by Millard reactions at 121 ᵒc for 1/4 hour by autoclaving, Chitosan derivatives resulting from the interaction carried symbols (G td, M td), where t was reaction temperature, d reaction time, either symbols (G and M) represents the sugar (glucose and maltose) respectively, the derivatives identify by GC-MS, the results shows the derivative (chitosan -glucose) (G121-1/4) hour contain 5 compounds, While the derivative (chitosan- maltose) (M121-1/4) hour contain 2 compound ,It was identify the molecular formula, molecular weight and the percentage of the area and the time of detention for each compound of these compounds. Determined the antioxidant activity of its and the result shows that the derivative(G121-1/4) hour was more significant than (M121-1/4) hou and have 85.80% of antioxidant activity, while the derivative (M121-1/4) hour have 80.30% . | ||
