A Comparative Study Of The Fractionation Of Regular Buttermilk And Whey Buttermilk By Microfiltration, Pierre Morin, Yves Pouliot, Rafael Jiménez-Flores Dec 2006

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 ...


Influence Of Ph And Heat Treatment Of Whey On The Functional Properties Of Whey Protein Concentrates In Yoghurt, Isabelle Sodini, Jerry Mattas, Phillip S. Tong Dec 2006

Influence Of Ph And Heat Treatment Of Whey On The Functional Properties Of Whey Protein Concentrates In Yoghurt, Isabelle Sodini, Jerry Mattas, Phillip S. Tong

Dairy Science

Our aim was to investigate how two conditions of whey processing, pH and heat treatment, affect the physical properties of stirred yoghurts fortified to 45 g protein kg−1 with whey protein concentrates (WPC). Cheddar whey was heated at pH 6.4 or pH 5.8 at 72 °C for 15 s, eventually heated further at 82 or 88 °C for 78 s, ultrafiltered, and spray dried. Resulting WPC contained 38% protein; the denaturation level of the whey protein was 10–53%. There were significant (P

Dairy Science

Dendritic cells (DC) are often arranged in planar layers in tissues with high antigenic exposure, such as skin and mucosae. Providing an en face view, this arrangement optimizes in situ analysis regarding morphology (even of individual dendrites), topographic distribution (regular/clustered) and quantification. The few reports on human genital DC usually utilize single markers and conventional sections, restricting immunolabelling only to cell parts sectioned by the cut. To better assess DC in situ, we labelled epithelial sheets, prepared from fresh cervix biopsies, with antibodies to major histocompatibility complex (MHC)-CII, CD1a and Langerin, revealing (with each of these markers) a ...
