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,...
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...
The Impact of the Malolactic Fermentation in the Volatile Composition of Trinca...
Torres, Mª Pietra; Cabrita, M.J.; Gomes da Silva, M.D.R.; Palma, Vera; Costa Freitas, A.M.Use of commercial starters for malolactic fermentation (MLF) is a common practice, and outcomes of this procedure are very relevant for wine producers because aroma attributes might change according to the strain used. MLF was carried out in the Trincadeira wine variety in three batches: spontaneously and with inoculation of two different commercial starters. Wine extracts before and after MLF were obtained thr...
Phenolic Acids, Phenolic Aldehydes and Furanic Derivatives in Oak Chips: Americ...
Cabrita, M.J.; Barrocas Dias, C.; Costa Freitas, A.M.Phenolic acids (gallic, vanillic, syringic and ellagic acids), phenolic aldehydes (vanillin, syringaldehyde, coniferaldehyde and sinapaldehyde) and furanic derivatives (furfural, 5-methylfurfural and 5-hydroxymethylfurfural) were quantified in commercial American and French oak chips. Chips with different sizes and toast degrees were used. Compounds were extracted directly from the wood samples in order to dete...
Sensorial analysis and electronic aroma detection to compare olive oils
Vaz-Freire, L.; Cabrita, M.J.; Gomes da Silva, M.D.R.; Costa Freitas, A.M.Sensorial analysis and electronic aroma detection to compare olive oils produced by different extraction methods. A sensorial analysis and an aroma analysis by electronic sensory devices were used to compare olive oils produced according to two different extraction methods. The extraction methods compared were the press system and two phase decanter. Samples were taken from the harvests of 2002-2004 and the oli...
