QUALITY OF 'SWEETHEART' CHERRY UNDER DIFFERENT STORAGE CONDITIONS
Agulheiro Santos, Ana Cristina; Palma, Vera; Rato, Ana Elisa; Machado, Maria da Graça; Lozano, Mercedes; Goncalez-Gomez, DavidAbstract: In Portalegre, Portugal, sweet cherry production is very important to the region’s economic sustainability. The sweet cherry ‘Sweetheart’ has exhibited short shelf life in spite of being highly appreciated by consumers due to its organoleptic characteristics. In this trial, we evaluated fruit quality of ‘Sweetheart’ stored under different storage conditions: 1) cold conditions (1ºC and high humidity ...
Evaluation of different postharvest conditions to preserve the amount of bioact...
González-Gómez ., David; Bernalte Garcia, Maria Josefa; Ayuso Yuste, M.Conception; Fernández León, M.Fernanda; Rato, Ana E.; Palma, VeraSweet cherries (Prunus avium L.) ‘Sweetheart’ were harvested at different production regions from Portugal (Cova da Beira and Portalegre) and Spain (Valle de Jerte). Cherries were harvested at their commercial maturation according to the empirical knowledge of external color corresponding to good quality. Fruits were stored and evaluated in order to study their quality on the harvest day and during a period of ...
The conversion of hydroxycinnamic acids into volatile phenols (in a synthetic m...
Cabrita, Maria Joao; Palma, Vera; Patão, Raquel; Costa Freitas, Ana MariaThe conversion of p-coumaric acid, ferulic acid, and caffeic acid into 4-ethylphenol, 4-ethylguaiacol and 4-ethylcatechol was studied in Dekkera bruxellensis ISA 1791 under defined conditions in a synthetic medium and in a red wine. Liquid chromatography (HPLC-DAD) was used to quantify the phenolic acids, and gas chromatography (GC) coupled to a FID detector was used to quantify volatile phenols using a novel a...

Palma, Vera; Agulheiro Santos, Ana Cristina; Machado, Graça; Rato, Ana Elisa; Cabrita, Maria João; Lozano, Mercedes; Gonzalez, DavidAbstract 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 atmosph...
QUALITY EVALUATION OF 'SUNBURST' CHERRIES HARVESTED AT DIFFERENT RIPENESS STAGES .
Agulheiro Santos, Ana Cristina; Palma, Vera; Machado, Graça; Rato, Ana Elisa; Cabrita, Maria JoãoThe 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...
