The most widespread method applied for standardization of milk protein in cheese production isultrafiltration. In the current study, pasteurized, unhomogenized whole milk was ultrafiltered with APVultrafiltration system, 51 spiral wound, polysulfone membrane with 20000 Da molecular weight cut off (DDS,Nakskov, Denmark) at 50 ˚C, such that the pressure difference between the two sides of membran...

Present evidence points to the rapid formation of one or several mediators by proteolysis initiated by insulin and, possibly, other hormones. Mediators act intracellularly at a number of subcellular sites, including cytoplasm, mitochondria, endoplasmic reticulum, cell membrane, and nucleus (figure 9). These mediators control enzymes that are controlled by covalent phosphorylation. As a result, ...
