I have 0.2% Chitosan solution dissolved in 1% acetic acid and after filteration using 0.2 µm filter paper, small white particles perciptated I do not what these particles are. This the first time for me to encounter such problem. Do you have any idea about this?

These particles may be chitin residues that were not enough deacetylated during processing to obtain chitosan. Furthermore, deacetylation includes filtration steps, which may result in cellulose residues from the filter paper if it is scraped to remove the chitosan.
