Evaluating an Ultrasonic Flaw Detector-Based Method to Characterize Solubility of Whey Protein Concentrate

On the Calibration of Ultrasonic Flaw Detector

For the assessment performance of the ultrasonic flaw detector (UFD) equipment, various standard documents are referred to such as ASTM (E317), British Standard (BS-4331), Bureau of Indian Standard (IS-12666), and more. The methods of calibration are spelt in different tone in these documents while broadly serving the same purpose. In the present paper a comparison for the calibration procedure...

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...

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...

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...
