This new process is done using an organic acid as a pretreatment and then using CO2 supercritical fluid to remove sericin from silk fiber. This method would be a huge break from the traditional environmentally unsustainable methods used today. This new processing method keeps the removed sericin in a clean state that can be used as a highly marketable silk protein in the medical and cosmetic industries.展开更多
