Commercial refined cane sugars still contain high-molecular-impurities such as acidified-ethanol-insoluble substances and turbid substances. These impurities were able to be satisfactorily eliminated by ultrafiltration and sufficiently by reverse osmosis. Ultrafiltration might be used for the production of specially pure sucrose free from these impurities. A small amount of these high-molecular-impurities reduced the flux in ultrafiltration of the sugar solution. From the degree of decline in flux, the level of these impurities in different sugars may be roughly judged.
