SOUZA, Rosane R; GIMENES, Marcelino L; COSTA, Sílvio C y MULLER, Carmen M.O. Fat Removal from Whey to Obtain Proteins and Lactose. Inf. tecnol. [online]. 2008, vol.19, n.2, pp. 41-50. ISSN 0718-0764. http://dx.doi.org/10.4067/S0718-07642008000200006.
Pre-treatment processes to remove fat and mineral salts from acid whey in order to recover its proteins and lactose contents were studied. Separation processes such as centrifugation and thermocalcic precipitation followed by microfiltration were analyzed. The centrifugation process combined with microfiltration process was more efficient for removing fat, resulting in an average lactose and protein recovery of 90%.
