Acorn flour from holm oak (Quercus rotundifolia): Assessment of nutritional, ph...
Martins, Rita Beltrão; Gouvinhas, Irene; Nunes, Maria Cristiana; Ferreira, Luís Mendes; Peres, José A.; Raymundo, Anabela; Barros, Ana I.R.N.A.Acorn is the fruit of holm oak (Quercus rotundifolia), being mainly used nowadays to feed animals, however a substantial part remains in the fields without any valorization. Underexploited crops are gaining new interest, driven by food security concerns and health benefits potential as well. In the present work, it was studied the physicochemical characteristics and functional perspective of acorn flour, as an ...
Acorn flour as a source of bioactive compounds in gluten-free bread
Martins, Rita Beltrão; Gouvinhas, Irene; Nunes, Maria Cristiana; Peres, José Alcides; Raymundo, Anabela; Barros, Ana I.R.N.A.Polyphenols are important bioactive compounds whose regular ingestion has shown di erent positive impacts in health. Celiac patients have nutritional deficiencies, bringing many problems to their health. Thus, it is important to develop gluten-free (GF) products, such as bread, with nutritional benefits. The acorn is the fruit of holm oak and cork oak, being an underexploited resource nowadays. Its nutritional ...
Physiological and biochemical performance of almond trees under deficit irrigation
Prgomet, Iva; Pascual-Seva, Núria; Morais, Maria Cristina; Aires, Alfredo; Barreales, David; Ribeiro, A.C.; Silva, A.P.; Barros, Ana I.R.N.A.The almond tree is generally recognized as drought-tolerant, though it depends on water resources to achieve high yields. During the summer months of two consecutive years, several physiological and biochemical parameters were observed, to understand the almond tree’s seasonal sensitivity and behavior under different irrigation strategies based on crop evapotranspiration (ETc): T100 optimal water requirement re...
Weather year-to-year variations determine the influence of kaolin and salicylic...
Brito, Cátia; Dinis, Lia Tânia; Silva, Ermelinda; Gonçalves, Alexandre; Rodrigues, M.A.; Moutinho-Pereira, José; Barros, Ana I.R.N.A.Olive tree (Olea europaea L.) growing area is threatened by the current and predicted adverse environmental conditions, affecting negatively the quality of the olive products, largely known for its benefits in human diet. Thus, agronomic strategies may be implemented to offset those negative effects. During two consecutive years young olive trees under rainfed conditions were sprayed in the beginning of the sum...
Kaolin and salicylic acid foliar application modulate yield, quality and phytoc...
Brito, Cátia; Dinis, Lia Tânia; Silva, Ermelinda; Gonçalves, Alexandre; Matos, Carlos; Rodrigues, M.A.; Moutinho-Pereira, José; Barros, Ana I.R.N.A.Olive orchards, rainfed managed, are threatened by the current and predicted adverse environmental conditions, which change the yield and quality of olive products, largely known for its benefits to human health. To mitigate these problems, it is highly recommended to perform some adjustments in agronomic practices, such as the use of foliar sprays that cloud help the trees to cope with climate change. During t...
Efeito da rega e da aplicação de caulino nas características sensoriais e parâm...
Prgomet, Iva; Barros, Ana I.R.N.A.; Pascual-Seva, Núria; Oliveira, Ivo; Morais, Maria Cristina; Afonso, Sílvia Martins; Bernardo, Sara; Ribeiro, A.C.Em Portugal, a amêndoa é uma cultura tradicional, que se encontra distribuída pelas regiões do Alentejo, Algarve e Trás-os-Montes, sendo, juntamente com a castanha, a mais produzida dos frutos de casca rija. Os amendoais são geralmente tradicionais, de sequeiro, sem técnicas de cultivo adequadas, o que leva a um baixo rendimento de produção. A produtividade, bem como a qualidade dos frutos, podem aumentar com a...
