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 ...

Research Progress in Imaging Technology for Assessing Quality in Wine Grapes and Seeds
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
The chemical composition of wine grapes changes qualitatively and quantitatively during the ripening process. In addition to the sugar content, which determines the alcohol content of the wine, it is necessary to consider ...

First insights into the binding mechanism and colour effect of the interaction of grape seed 11S globulin with malvidin 3-O-glucoside by fluorescence spectroscopy, differential colorimetry and molecular modelling
(Elsevier Ltd, 2023-07-01)
Recently, the search for alternative proteins endogenous to grapes to be used as wine colour protecting agents became an important research trend. In this study, the molecular interaction between the grape seed 11S globulin ...

A study of overripe seed byproducts from sun-dried grapes by dispersive raman spectroscopy
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)
Overripe seeds from sun-dried grapes submitted to postharvest dehydration constitute a scarcely investigated class of vinification byproduct with limited reports on their phenolic composition and industrial applications. ...
