A method for the production of sialic acid and glycoproteins in kaeser by means of a or casein preparation obtained operated deionized

摘要

A process for the separation of sialic acid and glycoproteins from dairy or casein factory whey. The proteins are flocculated by thermal treatment, the supernatent is ultrafiltrated and the ultrafiltration retentate is treated by hydrolysis, and the sialic acid is then extracted from the hydrolysis supernatent.
