Study of membrane ageing and grafting mechanisms using electron paramagnetic ...
Oliveira, Fábio R. P.; Matos, Cristina T.; Moura, José J. G.; Portugal, Carla A. M.; Crespo, João G.An important setback for a wider use of membrane processes in industry is fouling, caused by aggregation of biomolecules at membrane surface and pores. Two important approaches to reduce this effect are the use of chemical cleaning procedures and the functionalisation of the membrane surface. However, both processes may lead to membrane degradation and structure alteration due to free radical formation or ra...
Accessing gelling ability of vegetable proteins using rheological and fluoresce...
Sousa, Isabel; Batista, Ana Paula; Portugal, Carla A.M.; Crespo, João G.; Raymundo, AnabelaThis work aims to present a comprehensive study about the macroscopic characteristics of globular vegetable proteins, in terms of their gelling ability, by understanding their molecular behaviour, when submitted to a thermal gelling process. The gels of soy, pea and lupin proteins were characterized by rheological techniques. Gelation kinetics, mechanical spectra, as well as the texture of these gels were analy...
