ABSTRACT OF DISCLOSURE A process for the separation of sialic acid and glycoproteins from dairy ox casein factory whey. The proteins are flocculated by thermal treatment, the supernatent is ultra- filtrated and the ultrafiltration retentate is treated by hydrolysis. Sialic acid is then extracted from the hydrolysis supernatent. The process of the invention provides sialic acid and glycoproteins at a cost lower than conventional pro- cesses such as total or partial syntheses thereof.
