Factors Affecting the Denaturation and Aggregation of Whey Proteins in Heated Whey Protein Concentrate Mixtures

Controlled and tailored denaturation and aggregation of whey proteins

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...

Microparticulation of whey protein: related factors affecting the solubility.

Solubility of Simplesse 100, the only whey-based fat substitute, was found to be good, considering the fact that technology for preparation of Simplesse 100 is a sequence of thermal steps. To characterize this phenomen, gel chromatography on Sephadex G-100, Sephacryl S-1000 and SDS-PAGE were used, supported by high-speed separation, UV studies and analytical procedures. Results show that the un...

Effects of Ohmic Heating on Denaturation of Whey Proteins Solutions: Influence on Whey-Derived Products

Ohmic heating is one of the earliest applications of electricity in thermal processing of food and is receiving increased attention because of its uniform heating of liquids with faster heating rates, which presumably enables obtaining products of a superior quality to those processed by conventional heating technologies. Given the biochemical structure of proteins, it is expectable that ohmic ...

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...
