摘要 |
A process for sterilizing a polysaccharide composition containing chitosan, a chitosan derivative or a chitin derivative without substantially degrading the polysaccharide. The process has the steps of blending the polysaccharide in a solvent to form a solution or suspension; sterilizing the solution or suspension; dissolving suspended particles, if present; and then aseptically adjusting the pH of the sterilized solution. There is additionally provided a polyol stabilizing agent suitable for the polysaccharide composition.
