    • PROBLEM TO BE SOLVED: To provide a method for effectively producing a large amount of polyamine compositions at a high recovery from yeast fungus body contents. SOLUTION: This method for producing the polyamine composition through collecting polyamine includes: hydrolysing with alkali, Candidautilis and yeast fungus body contents such as Candidautilis; passing the product into a column in which positive ion exchange resin is filled to stick polyamine to the positive ion exchange resin; passing salt water into the column to elute stuck polyamine by hydrochloric acid; neutralizing the product followed by desalting by electrodialysis, and freeze-drying the product.
