This invention provides a method capable of easily determining with high accuracy a protein in chitosan, said protein having a potential relevance to the development of an allergy, specifically tropomyosin and the content of the peptide. According to the method, tropomyosin is determined by immunoassay with the chitosan being in a state dissolved in an aqueous solution of an organic acid. The present invention also provides chitosan, which has a measurement value of the protein, specifically tropomyosin not higher than a predetermined value as measured by the determination method and is assessed to have only a low risk of inducing the allergy. |
