PROBLEM TO BE SOLVED: To provide a method of tropomyosin determination by which the content in chitosan of proteins which may cause an allergic reaction, especially tropomyosin and peptide thereof easily with satisfactory precision, and to provide chitosan in which the found value obtained by the determination method is not higher than a certain value and which is judged to be less apt to cause an allergic reaction. SOLUTION: In the method of tropomyosin determination, the tropomyosin in the chitosan is determined by an immunoassay method in the state where chitosan is dissolved in an aqueous solution of an organic acid.
