Clean labelling sodium nitrite at pilot scale: in-situ reduction of nitrate fro...
Carvalho, Teresa Bento de; Oliveira, Mónica; Gomes, Ana Maria; Monteiro, Maria João; Pintado, Manuela; Komora, Norton; Durães, Tiago; Nunes, Fernando M.Growing health and environmental concerns have increased demand for all-natural products, with a focus on clean labelling. Sodium nitrite is the most widely used additive in the meat industry because it imparts the typical cured flavour and colour to meat products and, most importantly, their microbiological safety. However, due to health concerns, the European Commission is proposing revised regulations to red...
Combining zeolites with early-maturing annual legume cover crops in rainfed orc...
Martins, Sandra; Silva, Ermelinda; Brito, Cátia; Pinto, Luís; Martins-Gomes, Carlos; Gonçalves, Alexandre; Arrobas, Margarida; Rodrigues, M.A.Under climate change threats, there is a growing need to adapt the conventional agronomic practices used in rainfed olive orchards by sustainable practices, in order to ensure adequate crop yield and olive oil quality and to preserve soil health. Therefore, for two years, the effects of conventional tillage practice (T) and two sustainable soil management strategies, a leguminous cover crop (LC) and its combina...
Synergy between zeolites and leguminous cover crops improved olive tree perform...
Martins, Sandra; Brito, Cátia; Silva, Ermelinda; Gonçalves, Alexandre; Arrobas, Margarida; Pereira, Ermelinda; Rodrigues, M.A.; Nunes, Fernando M.Soil degradation and climate change are threatening the sustainability of Mediterranean olive orchards, typically grown under rainfed conditions and conventional soil tillage. Thus, implementing sustainable soil management practices is crucial to preserve soil health and mitigate the negative effects on plant performance. In this study, we assessed the effects of conventional tillage (T), an early maturing and ...
Zeolites and Biochar modulate olive fruit and oil polyphenolic profile
Martins, Sandra; Silva, Ermelinda; Brito, Cátia; Martins-Gomes, Carlos; Gonçalves, Alexandre; Arrobas, Margarida; Rodrigues, M.A.; Correia, Carlos M.Soil degradation processes and climate change threaten the sustainability of Mediterranean rainfed olive orchards, with repercussions on crop yield and quality of olives, olive oil and olive by-products. Using soil amendments can enhance soil fertility for sustained environmental quality and plant performance. For two years, we evaluated, under rainfed conditions, the effects of a fertilizer compound (FC) and i...
Soil amendment with Zeolites and Biochar influenced soil properties, photosynth...
Martins, Sandra; Silva, Ermelinda; Brito, Cátia; Martins-Gomes, Carlos; Gonçalves, Alexandre; Arrobas, Margarida; Rodrigues, M.A.; Nunes, Fernando M.Olive orchards represent a key agricultural system in the Mediterranean basin. Soil degradation processes associated to unsustainable agronomic practices and climate change could severely impact the sustainability of Mediterranean rainfed olive orchards. In this context, soil amendments are important tools that can be used to enhance soil fertility for sustained environmental quality and plant performance. For ...
Aplicação de revestimentos na castanha
Ramalhosa, Elsa; Pereira, Ermelinda; Laranjo, José Gomes; Ferreira-Cardoso, Jorge; Gomes, A.; Vilela, Alice; Sampaio, Ana; Nunes, Fernando M.No presente capítulo pretende-se descrever as atividades realizadas no âmbito do Projeto ValorCast ao nível da aplicação de revestimentos hidrofílicos e hidrofóbicos com o intuito de reduzir a desidratação das castanhas após a colheita. Para a avaliação de revestimentos hidrofílicos foram realizados quatro estudos, nos quais se avaliou a aplicação dos seguintes compostos: (i) alginato, quitosano e proteína do s...
Bioactive polysaccharides from medicinal mushrooms: A review on their isolation...
Garcia, Juliana; Rodrigues, Francisca; Saavedra, Maria José; Nunes, Fernando M.; Marques, GuilherminaMushrooms either alone or in combination with conventional cancer treatment have been enhanced the efficacy of chemotherapy and radiotherapy improving the patients' quality of life. These therapy effects have been attributed to polysaccharides; the most potent compounds found in the fungi kingdom. Due to their wide range of biological activity and the backbone of glucose residues linked by β-(1 → 3)-glycosidic ...
Major anthocyanins in elderberry effectively trap methylglyoxal and reduce cyto...
Ferreira, Sandrine S.; Domingues, M. Rosário; Barros, Cristina; Santos, Sónia A.O.; Silvestre, Armando J.D.; Silva, Amélia M.; Nunes, Fernando M.The accumulation of advanced glycation end-products (AGEs) in the body is implicated in numerous diseases, being methylglyoxal (MGO) one of the main precursors. One of the strategies to reduce AGEs accumulation might be acting in an early stage of glycation by trapping MGO. Thus, this work aimed to evaluate, for the first time, the potential of elderberries polyphenols to trap MGO, access the formation of MGO a...
Comparative antioxidant and antimicrobial properties of Lentinula edodes Donko ...
Garcia, Juliana; Afonso, Ana Cristina; Fernandes, Conceição; Nunes, Fernando M.; Marques, Guilhermina; Saavedra, Maria JoséThe problematic increase in multidrug-resistant bacteria translates into the urgent need to discover novel and effective antimicrobial substances. Herein, mushrooms could be a promising alternative of natural source of new antimicrobials. The present work aimed to compare the phytochemical composition and antimicrobial activity of methanol and aqueous crude extracts of Lentinula edodes var. Koshin and Donko. Di...
Use of leguminous cover crops as a sustainable strategy on rainfed olive orchar...
Martins, Sandra; Gonçalves, Alexandre; Silva, Ermelinda; Brito, Cátia; Rodrigues, M.A.; Nunes, Fernando M.; Correia, Carlos M.Olive tree is one of the most important crops in the Mediterranean basin with a huge social and economic impact. Considering the predicted scenarios of climate change, there is a growing need for the adaptation of agronomic practices, in order to mitigate the negative effects of those changes on plant physiology, yield, and olive fruit and oil quality. However, in Portuguese rainfed orchards the most frequently...
