Comparative Study of Phenolic Profile, Antioxidant Capacity, and Color-composition Relation of Roselle Cultivars with Contrasting Pigmentation
(Springer Nature, 2016)
Roselle is a plant that accumulates anthocyanins significantly, hence its importance as food coloring and as a source of antioxidant compounds for human health. This study was aimed to determine phenolic composition and ...

Preliminary study to determine the phenolic maturity stage of grape seeds by computer vision
(Elsevier, 2012-06-30)
The applications of computer vision technology for acquiring and analysing images have been extended to the quality evaluation in food industry. This technique involves great advantages for the objective, rapid, non-contact ...

Use of near infrared hyperspectral tools for the screening of extractable polyphenols in red grape skins
(Elsevier, 2015)
Hyperspectral images of intact grapes were recorded at harvest time using a near infrared hyperspectral imaging system (900–1700 nm). Spectral data have been correlated with red grape skin extractable poly- phenols (total ...

Assessment of the differences in the phenolic composition and color characteristics of new strawberry (Fragaria x ananassa Duch.) cultivars by HPLC–MS and Imaging Tristimulus Colorimetry
(Elsevier, 2015)
The phenolic composition (by HPLC-DAD-MS) and color characteristics (by Imaging Tristimulus Colorimetry) of four strawberry cultivars that have shown good climate adaptation to subtropical area (Nikte, Zamorana, Jacona and ...

Feasibility Study on the Use of Near-Infrared Hyperspectral Imaging for the Screening of Anthocyanins in Intact Grapes during Ripening
(American Chemical Society, 2013)
The potential of near-infrared hyperspectral imaging to determine anthocyanins in intact grape has been evaluated. The hyperspectral images of intact grapes during ripening were recorded using a near-infrared hyperspectral ...

Impact of a post-fermentative maceration with overripe seeds on the color stability of red wines
(Elsevier Ltd, 2019-01-30)
With the purpose of modulating the copigmentation equilibria of red wines, an environmentally sustainable process was performed based on post-fermentative addition of overripe seeds (OS). Simple (SW) and double (DW) addition ...
Tesis Doctoral
Aplicación de técnicas espectroscópicas vibracionales al estudio de la extractabilidad de compuestos fenólicos procedentes de subproductos enológicos.
(2019-01-23)
Las características de la uva en el momento de la vendimia condicionan en gran medida la calidad del vino elaborado a partir de ellas. En regiones de clima cálido, las altas temperaturas ambientales, acentuadas en las ...

Seguimiento de la maduración de variedades de uva mediante colorimetría y análisis de imagen de semillas
(Universidad de Alicante. Servicio de Publicaciones, 2010)
El seguimiento de la maduración de la uva se realiza mediante análisis fisicoquímico y organoléptico del mosto, siendo el momento de la vendimia un aspecto que repercute directamente en la calidad de un vino. La visión ...

Application of imaging techniques for the evaluation of phenolic maturity of grape seeds
(Sociedad Española de Óptica, 2017)
Quality of wine depends fundamentally on the condition of the components of grapes at the moment of harvest. In this respect, their seeds directly affect to structure, astringency, stability, and indirectly to colour of ...
