A Comparative Study Of The Fractionation Of Regular Buttermilk And Whey Buttermilk By Microfiltration, Pierre Morin, Yves Pouliot, Rafael Jiménez-Flores

Dairy Science

The use of a ceramic microfiltration (MF) membrane for the fractionation of buttermilk and whey buttermilk obtained from pilot scale churning of cream and whey cream from industrial sources has been studied. Whey buttermilk contained comparable amounts of phospholipids compared to regular buttermilk but its protein content was lower due to the absence of caseins. However, it was found that lipid content of whey cream did vary significantly between lots resulting in important variations in the fat content of whey buttermilk. A twofold MF concentration of regular buttermilk doubled its phospholipids content whereas that of whey buttermilk was increased by …
