RECIO, ISIDRA ; GARCÍA-RISCO, MÓNICA R. ; LOPEZ FANDIÑO, ROSINA ; RAMOS, MERCEDES ; OLANO, AGUSTÍN | 2000The fraudulent presence of rennet whey solids in UHT milk was studied by capillary electrophoresis (CE). Commercial UHT samples of different origins, genuine milk samples and milk samples adulterated with rennet whey were analysed. Linear discri[...]

Quantitative analysis of major whey proteins by capillary electrophoresis using uncoated capillaries
RECIO, ISIDRA, Autor ; ELENA MOLINA, Autor ; RAMOS, MERCEDES, Autor ; MERCEDES DE FRUTOS, Autor | 1995A method that allows separation and quantitation of the main whey proteins by capillary electrophoresis using uncoated capillaries is proposed. Separations are performed using 100 mM borate buffer, pH 8.2, containing 30 mM sodium sulfate. The us[...]

The proteolytic activity of enzymes of psychrotrophic bacteria on casein and raw and ultra-high-temperature (UHT)-treated milk was studied by capillary electrophoresis (CE) in order to characterize the degradation products and evaluate the possi[...]
