Goats' milk as a natural source of lactose-derived oligosaccharides: Isolation by membrane technology

摘要: Abstract Human milk oligosaccharides are thought to be beneficial for the infant with regard their prebiotic and anti-infective properties. However, so far no from farm animals has been considered a good natural source of lactose-derived human nutrition. In this study, characterization quantitation neutral sialylated in mature caprine was performed compared ovine, bovine milk. The quantification carried out using high-pH anion-exchange chromatography pulsed amperometric detection (HPAEC-PAD), by fast atom bombardment mass spectrometry (FAB-MS). A large amount variety acidic were found goats’ when cow sheep addition, 15 new oligosaccharide structures identified order isolate fraction, two-stage tangential ultrafiltration–nanofiltration process selected. Tubular ceramic membranes molecular cut-offs 50 1 kDa, respectively, employed. virtually lactose salts-free product containing more than 80% original content obtained.
