Development of aroma-synthesising capacity throughout fruit maturation of ‘Mondial Gala’ apples
(Taylor & Francis, 2008)Emission of aroma volatile compounds (AVCs) and the activity of some related enzymes were monitored during ontree maturation of ‘Mondial Gala’ apples. Volatile esters were quantitatively prominent among the AVCs ... -
Differential contribution of the two major polygalacturonases from Penicillium digitatum to virulence towards citrus fruit
(Elsevier, 2018-10)The fungus Penicillium digitatum is the causal agent of the citrus green mould, the major postharvest diseases of citrus fruit. Lesions on the surface of infected fruits first appear as soft areas around the inoculation ... -
Direct determination of free metal concentration by implementing stripping chronopotentiometry as second stage of AGNES
(The Royal society of Chemistry, 2011)The electroanalytical technique Absence of Gradients and Nernstian Equilibrium Stripping (AGNES) has been extended by applying stripping chronopotentiometry (SCP) as the re-oxidation stage in the determination of the free ... -
Dispersive liquid–liquid microextraction and injection-port derivatization for the determination of free lipophilic compounds in fruit juices by gas chromatography-mass spectrometry
(Elsevier, 2017)A method consisting of dispersive liquid–liquid microextraction (DLLME) followed by injection-port derivatization and gas chromatography-mass spectrometry (GC–MS) for the analysis of free lipophilic compounds in fruit ... -
Dissolution and phosphate-induced transformation of ZnO nanoparticles in synthetic saliva probed by AGNES without previous solid-liquid separation. Comparison with UF-ICP-MS
(American Chemical Society, 2019-02-26)The variation over time of free Zn2+ ion concentration in stirred dispersions of ZnO nanoparticles (ZnO NPs) prepared in synthetic saliva at pH 6.80 and 37 degrees C was followed in situ (without solid liquid separation ... -
Dissolution Kinetics and Solubility of ZnO Nanoparticles Followed by AGNES
(American Chemical Society, 2012)There is a current debate on whether the toxicity of engineered ZnO nanoparticles (NPs) can be traced back to their nanoscale properties or rather to the simple fact of their relatively high solubility and consequent ... -
Dissolved concentrations and organic speciation of copper in the Amazon River estuary and mixing plume
(Elsevier, 2021-06-24)The Amazon is Earth's largest river by volume output, making it an important source of trace metals and dissolved organic matter (DOM) to the Atlantic Ocean. Despite major recent anthropogenic disruptions to the Amazon ... -
Distribution of Dopant Ions Around Poly(3,4-ethylenedioxythiophene) Chains: A Theoretical Study
(Royal Society of Chemistry, 2017)The effect of counterions and multiple polymer chains on the properties and structure of poly(3,4-ethylenedioxythiophene) (PEDOT) doped with ClO4− has been examined using density functional theory (DFT) calculations with ... -
Does total antioxidant capacity play a central role in postharvest deterioration of 'Sweetheart' sweet cherry fruit?
(International Society for Horticultural Science (ISHS), 2017)'Sweetheart' cherries (Prunus avium L.) have sweet flavour, bright red colour and a distinctive heart shape which contributes to their wide commercial acceptance. They display also comparatively high firmness and long ... -
Dynamic changes in health-promoting properties and eating quality during off-vine ripening of tomatoes
(Wiley, 2018)Tomato (Solanum lycopersicon L.) fruit is rich in various nutrients, vitamins and health-promoting molecules. Fresh tomatoes are an important part of the Mediterranean gastronomy, and their consumption is thought to ... -
Dynamics of trace metal sorption by an ion-exchange chelating resin described by a mixed intraparticle/film diffusion transport model. The Cd/Chelex case
(Elsevier, 2017-06-01)The time-evolution of Cd2+ ion sorption by Chelex 100 resin was studied in batch experiments as a function of time, pH, ionic strength, stirring rate, mass of resin and initial metal ion concentration. In the experimental ... -
Early-life exposome and lung function in children in Europe: an analysis of data from the longitudinal, population-based HELIX cohort
(Elsevier, 2019-02-06)Background: Several single-exposure studies have documented possible effects of environmental factors on lung function, but none has relied on an exposome approach. We aimed to evaluate the association between a broad range ... -
Eating quality and health-promoting properties of two sweet cherry (Prunus avium L.) cultivars stored in passive modified atmosphere
(SAGE Publications, 2015)Two sweet cherry cultivars ('New Star' and 'Sweet Heart') were chosen to explore the impact of passive modified atmosphere packaging on the eating quality and health-promoting properties of fruit. Packaged and unpackaged ... -
Eating quality of 'Fuji' apples affected by a period of cold air after ULO storage.
(John Wiley & Sons, 2012-02-01)Over two subsequent seasons, emission of volatile compounds, consumer acceptability and quality parameters were analyzed in “Fuji” apples. In both seasons, apples were harvested at the same maturity stage and stored for ... -
