Transmission of serum proteins (α-LA + β-LG), Tr, during skimmed milk filtration. Milk was microfiltered after (a) 48 h or (b) 96 h of 4 °C storage of raw milk and different microbiological stabilization methods (diamonds, 1.4 µm microfiltration for M-SMilk; squares, thermization for T-SMilk; solid and open circles, pasteurization for P1-SMilk and P2-SMilk, respectively). Error bars represent 1 experimental error value. Operating conditions: 0.1 μm ceramic membrane; uniform transmembrane pressure system; permeation flux, Jp = 75 L·h−1·m−2; volume reduction ratio = 3.0; T = 50 °C).
