Abstract
A chitosan-containing powder which contains chitosan particles formed by dissolving chitosan in an edible organic acid and spray-drying the solution. The molar ratio of the amount of the chitosan to that of the edible organic acid to be used for dissolving the chitosan may be about from 1/0.9 to 1/0.8. The molecular weight of the chitosan to be dissolved in the edible organic acid may be about 10,000 to 300,000. The degree of deacetylation of the chitosan to be dissolved in the edible organic acid may be about 90% or higher. The chitosan-containing powder has a higher chitosan content than conventional ones.
