Matching the sensory analysis of Serpa PDO cheese with the volatile profiles—a ...
Macedo, Antónia; Carvalho, Maria João; Mecha, Elsa; Costa, Leonor; Ferreira, António; Inácio, Rita S.; Bronze, Maria do RosárioSerpa cheese, a Portuguese Protected of Denomination Origin (PDO) cheese, known for its unique sensory attributes, is made from the raw milk of native sheep. In this preliminary work, ten samples of Serpa cheese were submitted for a sensory evaluation performed by an expert panel in a sensory laboratory accredited according to ISO 17025 for Serpa cheese parameters, and the panelists classified the cheeses based...

A pilot plant scale testing of the application of seaweed-based natural coating...
Augusto, Ana; Miranda, Andreia; Costa, Leonor; Pinheiro, Joaquina; Campos, Maria J.; Raimundo, Délio; Pedrosa, Rui; Mitchell, GeoffreyCodium tomentosum hydroethanolic extract was obtained using a pilot solid–liquid extractor to validate the anti-browning functionality of the extract under industrial conditions. Fresh-cut apple slices were coated by immersion in: (1) a seaweed extract solution (0.5% w/v) and (2) a commercial coating, and the two sets of samples were compared with a control (immersion in water). Packaged samples were stored, un...

Multi-step subcritical water extracts of fucus vesiculosus l. And codium toment...
Soares, Cristina; Paíga, Paula; Marques, Marta; Neto, Tânia; Carvalho, Ana Paula; Paiva, Alexandre; Simões, Pedro; Costa, Leonor; Bernardo, AnaMental health and active aging are two of the main concerns in the 21st century. To search for new neuroprotective compounds, extracts of Codium tomentosum Stackhouse and Fucus vesiculosus L. were obtained through multi-step (four step) subcritical water extraction using a temperature gradient. The safety assessment of the extracts was performed by screening pharmaceutical compounds and pesticides by UHPLC-MS/M...

Unveiling the Ambrotype: Characterization of Two 19th Century Photographs
Costa, Leonor; Nunes, Margarida; Costa, Sónia; Trindade, Milne; Miguel, Catarina; Ferreira, TeresaThis work used a multi-analytical approach to characterize two 19th century ambrotypes and was motivated by the lack of insight on these historical objects. Photographic imaging and optical microscopy (OM) were used to identify abrasions, cracks related to reticulation, tarnishing, and other aspects associated to production and degradation processes. With variable pressure scanning electron microscopy coupled w...
Morphological and chemical characterization of tintypes and ambrotypes
Costa, LeonorThe present work was done on two ambrotypes and two tintypes. It aimed evaluate their chemical and physical characteristics, especially their degradation patterns. Moreover, to understand the materials used for their production and cross-check analytical and historical information about the production processes. To do so multi-analytical, non-destructive methods were applied. Technical photography highlighted t...
Phagocytic cell responses to silica-coated dithiocarbamate-functionalized iron ...
Costa, Leonor; Mohmood, Iram; Trindade, Tito; Anjum, Naser A.; Duarte, Armando C.; Pereira, EduardaImmune system responses in fish are considered as suitable and sensitive biomarkers for monitoring aquatic pollution. However, a clear knowledge gap persists in the literture on the immunotoxic potential of engineered nanoparticles toward aquatic organisms such as fish. Employing major enzymatic- (glutathione reductase, GR; glutathione peroxidase, GPX; glutathione sulfo-transferase, GST; catalase, CAT) and thio...

Mohmood, Iram; Ahmad, Iqbal; Asim, Mohammad; Costa, Leonor; Lopes, Cláudia B.; Trindade, Tito; Duarte, Armando C.; Pereira, EduardaThe study aimed to assess the genotoxic potential of silica-coated iron oxide nanoparticle functionalized with dithiocarbamate groups (IONP, 100 nm) in vitro exposure alone or its interference with mercury (Hg) co-exposure in the blood of European eel (Anguilla anguilla L.) by evaluating 8-hydroxy-2′-deoxyguanosine (8-OHdG), lipid peroxidation (LPO), and erythrocytic nuclear abnormalities (ENA). Four groups wer...
