Goat milk shows similarities with human milk in terms of their oligosaccharides composition. However, the supplementation of goat milk protein in infant formulae is not allowed, which demands a previous separation of oligosaccharides from protein. The purpose of this study was to evaluate the effect of transmembrane pressure on the fractionation of oligosaccharides, protein, lactose and calcium in the diafiltration of caprine milk through a 50 kDa tubular ceramic membrane. Permeates with more than 99% of the original oligosaccharides were obtained after four diavolumes. It was seen that transmembrane pressure had a great influence on filtration time and protein transmission.
