Method of determining tropomyosin in chitosan

摘要

A method capable of easily determining with high accuracy a protein in chitosan, the 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 method 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.
