Short communication: isolation of a whey fraction rich in α-lactalbumin from skim milk using tangential flow ultrafiltration.
The objective of this research was to evaluate the potential for separating α-lactalbumin from pasteurized milk by using tangential flow membrane filtration. Filtration was carried out with a Purosep 7000 series membrane filtration unit (SmartFlow Technologies) with a regenerated cellulose membrane at 26°C and a transmembrane pressure of 186 kPa. The protein in the permeate was >80% α-lactalbum...
متن کاملwhey proteins of rabbit milk
Caseins were separated from whey proteins by acid precipitation of skimmed rabbit milk. Whole casein was resolved by sodium dodecyl sulphate/polyacrylamide-gel electrophoresis into three major bands with apparent relative molecular masses (Mr of 31 000, 29 000 and 25 000. On agarose/urea-gel electrophoresis whole casein gave three bands with electrophoretic mobilities a, , and y. The three comp...
متن کاملCharacterization of Milk Proteins in Ultrafiltration Permeate and Their Rejection Coefficients
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...
متن کاملThe Quality of The UHT Skim Milk as Affected by Addition of Rennet Skim Milk
Background and Objectives: Consumption of whole dairy products has declined due to the awareness of possible harmful effects of fat on consumers’ health. The purpose of the present paper was to investigate the possibility of substituting the Ultra-high temperature processing (UHT) whole milk with partially hydrolyzed κ-casein to manufacture a UHT skim milk. Materials and Methods: UHT skim milk ...
متن کاملNovel angiotensin-converting enzyme inhibitory peptides from caseins and whey proteins of goat milk
Angiotensin-converting enzyme (ACE) plays a central role in blood pressure regulation by producing the vasoconstrictor angiotensin II. The inhibition of ACE with natural inhibitors, as alternatives to avoid the side effect of synthetic drugs, is a major target in the prevention of hypertension. In this study, we examined the separated caseins and whey proteins of goat milk for the presence of A...
