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...

in this study, the effect of retentate and whey protein concentrate in different concentrations on the properties of low fat synbiotic yoghurt was studied. retentate samples containing different concentrations of the three concentrations ( 0.5 , 0.75 and 1 %) and whey protein concentrate ( 0.2 , 0.3 and 0.4 %) were prepared and characterized in terms of physicochemical , rheological and sensory...

Crude extracts of tentacles of two polychaetous annelids completely inhibit growth of Erlich ascites tumor in 60 to 100 percent of treated mice. Dialyzed extracts of one of these annelids, Lanice conchilega, show activity in the retentate after pronase digestion, suggesting that antitumor activity is associated with a nonprotein component of the crude tentacle extract.

The enterotoxic material in cell-free growth preparations of Klebsiella pneumoniae serotype 5 was purified by sequential ultrafiltration and gel filtration (GF) procedures and the fractions were assayed for enterotoxic activity by determining their ability to induce in vivo net water secretion in the rat jejunum. Whole-cell lysates were inactive. Anaerobic broth culture conditions yielded a 10-...

in this study, ultrafiltrated feta cheese was prepared from cow’s milk ultrafiltraton retentate and soymilk blend. rennet and calcium chloride were used simultaneously as coagulant to coagulate cow’s milk proteins and soymilk proteins, respectively. then, the effect of storage period on physical (texture profile analysis test, penetration test), chemical (total solids, protein, fat) and sensory...
