Purification of β-Lactoglobulin from Whey Protein Concentrate by Pepsin Treatment

Whey Protein Concentrate (wpc) and Glutathione Modulation

The glutathione antioxidant system is foremost among the cellular protective mechanisms. Depletion of this small molecule is a common consequence of increased formation of reactive oxygen species during increased cellular activities. This phenomenon can occur in the lymphocytes during the development of the immune response and in the muscular cells during strenuous exercise. It is not surprisin...

Production and purification of lactase of Kluyveromyces fragilis from whey

Density, Viscosity and Surface Tension of Whey Protein Concentrate Solutions

We have determined the density, rheological behavior and surface tension of whey protein concentrate (WPC) solutions. Densities (r) were measured at concentrations of 0.05–0.40 w/w at temperatures of 20–35C. The results were expressed as a function of temperature and mass fraction (w). This function fit the data with deviations of less than 0.4%. Apparent viscosities (ha) for WPC solutions with...

Purification of Pepsin

Since 1836, when Theodor Schwann signalized the presence in gastric juice of the proteolytic ferment which he was the first to designate as pepsin, a large number of attempts have been made to isolate it in a pure form to determine its chemical nature and its ultimate physiological properties. In a large majority of these, and, especially, all those made before 1895, except that of Brticke (I),...
