Effect of Different Storage Conditions on Nutritional and Quality
Palma, V.; Agulheiro-Santos, A.C.; Machado, G.; Rato, A.E.; Cabrita, M.J.; Lozano, M.; Gónzález, D.The sweet cherry ‘Sweetheart’, although having a short shelf life, is highly appreciated by consumers due to its organoleptic characteristics. Different storage methods were tested to study the maintenance of quality during a period of 27 days: 1) cold (air at 1°C and 95% relative humidity) (CC), 2) cold and polypropylene film bags (1°C and 95% relative humidity) (MA) and 3) cold and controlled atmosphere (1°C,...
INFLUENCE OF CELL WALL CALCIUM CONTENT IN FRUIT FIRMNESS DURING THE RIPENING OF...
Rato, A.E.; Nunes, C.; Agulheiro-Santos, A.C.; Barroso, J.M.; Coimbra, M.A.; Riquelme, F.‘Rainha Claudia Verde’ is a regional cultivar of Prunus domestica L. well adapted to a specific region in the south of Portugal. In order to understand the postharvest behavior of this cultivar produced in different orchards, cell wall poly-saccharides and cell wall calcium fruit content were studied during ripening in two consecutive years. During harvest period pectic fractions soluble in water, carbonate and...
Quality Evaluation of ‘Sunburst’ Cherries Harvested at Different
Agulheiro-Santos, A.C.; Palma, V.; Machado, G.; Rato, A.E.; Cabrita, M.J.The sweet cherry ‘Sunburst’ is highly appreciated by consumers due to its organoleptic traits. Regional producers tend to harvest cherries sooner in order to increase their profits. With the aim of understanding the consequences of this we have tested the effect of different ripeness stages at the moment of harvesting on fruit quality. Quality parameters tested included external colour (L*, a*, b*), fruit textu...
Resposta do olival intensivo e super-intensivo a dois regimes de rega: parâmetr...
Coelho, R.; Vaz, M.; Santos, F.L.; Sousa, A.; Rato, A.E.; Shahidian, S.; Paço, T.A.; Mota, M.; Nogueira, A.Olive grove irrigation has substantially increased in the past years on the region of Alentejo (southern Portugal). The correct determination of the plant water requirements is one of the key factors on the orchard management. This work evaluates the response of two varieties of Olea europaea, Cobrançosa in an intensive grove (hereafter named FEA) and Arbequina in a hedgerow orchard (hereafter named OSul), subj...
Estudo das modificações físico-químicas ocorridas durante a confitagem da Ameix...
Nunes, C.; Silva, J. A. L.; Santos, C.; Rato, A. E.; Barroso, J. M.; Rocha, S. M.; Saraiva, J.; Coimbra, M. A.Neste trabalho estudaram-se as alterações da microestrutura, textura e polissacarídeos da parede celular durante a confitagem da Ameixa dlElvas. Foram utilizadas ameixas não processadas ("Rainha Claudia Verde"), cozidas e confitadas. As células do parênquima das ameixas cozidas e as das confitadas, quando comparadas com as do fruto não processado, apresentaram degradação da parede celular primária, aumento do e...
