Fish discards are a worldwide phenomenon resulting from fisheries and have been the subject of great concern on the part of all players in the sector, whether they are government, fishermen or scientists. Numerous species of low or no commercial value are discarded every year and most of them have a high nutritional value. However, due to economic reasons and/or consumer acceptance, they do not reach our food c...
The search for healthier food products has increased the development of novel fish-based functional foods. In the present work the quality changes during refrigerated storage of meagre and sea bream hams enriched with dietetic fibers and packaged in modified atmosphere (30 % CO2 / 70 % N2) were evaluated. The fish hams had a good sensory acceptance and in microbiological terms were acceptable until at least 20 ...
The development of novel fish-based functional foods is increasing due to consumer’s search for healthier food products to create a daily balanced diet. The final goal of the present work was to evaluate the quality during refrigerated conditions of meagre ham enriched with dietetic fibers and packaged in vacuum and in modified atmosphere (20% or 40% CO2). The proximate chemical composition indicated that meagr...
This article describes a study carried out on the emblematic mural painting so-called ‘fresco of the good and bad judge’ located at the medieval village of Monsaraz (southern Portugal). This painting, with two distintic narratives, is thematically unique in Portugal and rare in the context of European Renaissance art. Scientific research was undertaken to clarify doubts about the chronology of the two painted s...

In this work, we present the results of an analytical method developed for detailed pigment identification, stratigraphy, and degradation of the paint layers of mural paintings applied in the study of the 17th century frescoes from the Misericordia Church of Odemira ~Southwest Portugal!. In situ X-ray fluores- cence spectrometry analyses were performed on three panels of the mural paintings and complemented by ...
A series of colour assays were conducted taking into account old bibliographic recommendations and oral testimony regarding traditional lime painting technology from the Alentejo (South Portugal) region. The main objectives were: (a) the colorimetric analysis of paintings made with different limewash preparation methods; (b)the comparison between natural processed red and yellows ochre pigments (‘‘home made’’ a...
Samples of blue wall paint layers from selected 15th to 18th century religious mural paintings from southern Portugal (Alentejo) have been analyzed using a multi-analytical methodology involving the combination of in situ visible spectro-colorimetry with microanalytical techniques such as optical and scanning electron microscopy and Raman spectroscopy. In situ analyses and micro-sampling were carried out in nin...
