Avaliação de serviços de ecossistema de conservação do solo associados a proces...
Guerra, Carlos; Pinto-Correia, Teresa; Metzger, M; Neiva, A; Alonso, JEstudos recentes mostram a necessidade de incorporar os conceitos de serviços de ecossistema e de sistemas sócio-ecológicos nos processos de planeamento e gestão dos espaços naturais. Esta necessidade reflete não só a importância dos ecossistemas, e dos serviços que lhes estão associados, para o sucesso dos processos de planeamento, mas também a relevância da implementação de estudos interdisciplinares que acr...
Anthocyanin pigments in strawberry
Lopes-da-Silva, M.F.; Escribano-Bailón, M.T.; Perez-Alonso, J.J.; Rivas-Gonzalo, J.C.; Santos-Buelga, CelestinoThe anthocyanin composition was analysed in strawberry fruits from five different cultivars (cv. Eris, Oso Grande, Carisma, Tudnew and Camarosa). Twenty-five defined anthocyanin pigments were detected, most of them containing Pelargonidin (Pg) as aglycone; some cyanidin (Cy) derivatives were also found. Glucose and rutinose were the usual substituting sugars, although arabinose and rhamnose were also tentativel...
Flavanol-anthocyanin condensed pigments in plant extracts
González-Paramás, A.M.; Lopes-da-Silva, M.F.; Martin-Lopez, P.; Macz-Pop, G.; Gonzalez-Manzano, S.; Alcalde-Eon, C.; Perez-Alonso, J.J.Pigments resulting from the direct condensation of anthocyanins and flavanols are usually associated with reactions taking place during processing and storage of plant-derived foods and beverages and have been particularly studied in aged red wines. In this paper, small amounts of flavanol-anthocyanin condensed pigments are found in different plant extracts. Structures are suggested for 10 such condensed pigmen...
Study of the thermal stability and enzymatic activity of an immobilised enzymat...
Vidal, M. M.; Gil, M. H.; Delgadillo, I.; Alonso, J.In this work, we have studied the immobilisation of the haemoglobin/glucose oxidase coupled enzymatic system in poly(vinyl alcohol) membranes. These are to be used as a reagent phase either in the development of an optical sensor or as an efficient bilirubin (BR) removal reactor. Poly(vinyl alcohol) (PVA) was chosen as the support for this purpose, due to its good biocompatibility, hydrophilicity and non-thromb...
