MIRALLES, BEATRIZ, Autor ; ROTHBAUER, VOLKER, Autor ; MANSO, MARIA A., Autor ; AMIGO, LOURDES, Autor ; KRAUSE, INGOLF, Autor ; RAMOS, MERCEDES, Autor | 2001A capillary electrophoresis method for the simultaneous determination of whey proteins, caseins and their degradation products, such as para-k-casein, was proposed. The effect of several parameters (pH, ionic strength and concentration of urea i[...]texto impreso
The influence of glycerol concentration on some physical properties such as the thermal, mechanical, water solubility, hydrophilicity and water barrier properties of feather keratin films was studied. Feather keratin was extracted with an aqueou[...]texto impreso
Research on edible and biodegradable films had been promoted recently because of environmental concerns. The use of these materials for packaging applications is conditioned by their functional properties, which are influenced by many factors, i[...]Article : documento electrónico
