Determination of soluble ultra-trace metals and metalloids in rainwater and atmospheric deposition fluxes: A 2-year survey and assessment
(Elsevier, 2013)
The present work investigates the relationships between composition of rainwater and dry deposition fluxes by trace metals and metalloids. A modification in automatic “wet-only” and “dry-only” samplers was applied, which ...

Excitation-emission fluorescence as a tool to assess the presence of grape-must caramel in PDO wine vinegars
(Elsevier Ltd, 2019-07-30)
A practice in wine vinegar production is the addition of grape-must caramel to correct and unify the final colour of different batches. Although current legislation allows it, the effect in vinegars’ quality has not been ...

Pre-fermentative addition of an enzymatic grape seed hydrolysate in warm climate winemaking. Effect on the differential colorimetry, copigmentation and polyphenolic profiles
(Elsevier, 2016-10-15)
The effect of adding an enzymatic hydrolysate of grape seeds (EH-GS) during Syrah wine fermentation in a warm climate has been evaluated. We focused on the polyphenolic composition as well as the application of differential ...

Improving the mining soil quality for a vegetation cover after addition of sewage sludges: Inorganic ions and low-molecular-weight organic acids in the soil solution
(Elsevier, 2015-03-01)
We assessed the effects of applying stabilized sewage sludge (SSL) and composted sewage sludge (CLV), at 5 and 10% to an acid mining soil. Limed soil (NCL) amended or not with SSL and CLV was incubated for 47 days. We ...

Impact of adding white pomace to red grapes on the phenolic composition and color stability of syrah wines from a warm climate
(American Chemical Society, 2014-03-26)
The influence of the fermentative addition of Pedro Ximenez grape pomace (PXGP, white variety) on the phenolic composition and color of Syrah red wines from a warm climate was studied. Changes on phenolic composition (HPLC), ...

Assessment of the sequential principal component analysis chemometric tool to identify the soluble atmospheric pollutants in rainwater
(Springer, 2011)
In this study a new method of principal component (PC) analysis, sequential PC analysis (SPCA), is proposed and assessed on real samples. The aim was to identify the atmospheric emission sources of soluble compounds in ...

Colour training and colour differences thresholds in orange juice
(Elsevier, 2013-12)
This study was aimed at training a panel of assessors to evaluate specifically orange juice colour, and to establish the colour difference threshold in orange juice for a trained and untrained panel. Panellists were first ...

Industrial orange juice debittering: Impact on bioactive compounds and nutritional value
(Elsevier, 2013-05)
The impact of an industrial debittering process (DP) on nutritional and bioactive compounds in orange juice (OJ) was studied. The DP was aimed at removing bitter components in OJ by physical adsorption in a resin. The ...

Digital Image Analysis and Visual Evaluation of Orange Juice: Influence of Different Measurements' Conditions
(Springer Nature, 2014-01)
This study assesses the effect of background, surrounding, thickness and dilutions on the colour specifications of orange juice (OJ) analyzed by digital image and visual evaluation. A commercial OJ was diluted with distilled ...
