[PROBLEMS] To solve the problems of conventional treatment methods using acids and alkalis and proteolytic enzymes, ie, (1) pretreatment such as pulverization, ultrasonic treatment and boiling treatment is necessary; It is an object of the present invention to provide an eggshell membrane solubilization method that can solve at least one of the problems of requiring treatment and (3) low degradation rate (about 20%). The eggshell membrane is efficiently solubilized by using a proteolytic enzyme and a reducing agent in combination. [Selection figure] None |
