Whey is the major by-product of cheese industry which contains valuable organic materials. Further processes are needed before these materials can be used in food industry. Membrane filtration a convenient alternative to traditional processes. Low energy consumption, reduced processing costs and enhanced quality products main benefits membrane filtration. Due advantages techniques have affected...

We describe the expression of recombinant fluorescent proteins in the milk of two lines of transgenic pigs generated by Sleeping Beauty transposon-mediated genetic engineering. The Sleeping Beauty transposon consisted of an ubiquitously active CAGGS promoter driving a fluorophore cDNA, encoding either Venus or mCherry. Importantly, the fluorophore cDNAs did not encode for a signal peptide for t...

Heat treatment during the production of skimmed milk powder causes denaturation of proteins, thereby affecting the physicochemical properties of the skimmed milk powder. To understand the effects of heat treatment on the sensitivity of the casein micelles in skimmed milk powders, low heating type (L), normal heating type (N), high heating type (H), and super-high heating type (SH), to reaction ...

A preparative isoelectric focusing (IEF) method was applied to separate skim milk proteins using the Rotofor device in a pH 3-10 gradient containing 4 M urealI % triton X-I 00. Each ofthe 20 fractions obtainedfrom the Rotofor device was then analyzed by polyacrylamide gel electrophoresis (PAGE). Both ureaPAGE and SDS-PAGE were used to separate purified caseins and skim milk resulting in compara...

Reaginic hypersensitivity in ulcerative colitis has been investigated in respect of a hypersensitivity to the cow's milk proteins and the frequency of atopic asthma, hay fever, and eczema. Intradermal tests were frequently positive, especially to casein, but the results did not differ from those found in healthy individuals and in groups of patients with Crohn's disease, hypolactasia, and the i...

Milk samples were collected from Holstein and Jersey breeds of dairy cattle maintained under the same management practices and environmental conditions over a seven-day period. Milk samples were collected twice daily from six cows of each breed as previously described (Tacoma et al., 2016) [1]. Samples were composited within individual cow over the experimental period and skimmed to remove the ...
