A novel and enhanced approach for the assessment of the total carotenoid content of foods based on multipoint spectroscopic measurements
(Elsevier, 2011-06-15)
We have devised a more sensible approach to estimate the carotenoid content of orange juices, which can be regarded as a model system of food with intricate carotenoid pattern. For this purpose spectroscopic information ...

Colorimetric characteristics of the phenolic fractions obtained from Tempranillo and Graciano wines through the use of different instrumental techniques
(Elsevier, 2012-06-30)
The aim of the present work was to determine whether there is any relationship between measurement by transmission and reflection (in the latter case, with and without contact with the sample). We also evaluated which ...

Effect of the time of cold maceration on the evolution of phenolic compounds and colour of Syrah wines elaborated in warm climate
(Wiley, 2014-08)
The effect of different cold maceration times on Syrah red wines from warm climate has been evaluated. Differential colorimetry and tristimulus colorimetry were applied to colour data at different points of the vinification ...

Comparative Study of the Enological Potential of DifferentWinemaking Byproducts: Implications in the Antioxidant Activityand Color Expression of Red Wine Anthocyanins in a Model Solution
(American Chemical Society, 2014)
Different white winemaking byproducts (pomace, skins, seeds, and stems) were compared as natural sources of phenolic compounds having biological and sensory properties of enological interest. Antioxidant and copigmentation ...

Application of LC-MS and tristimulus colorimetry to assess the ageing aptitude of Syrah wine in the Condado de Huelva D.O. (Spain), a typical warm climate region
(Elsevier, 2012-06-30)
The study of the evolutions of different wine pigment families, copigmentation/polymerisation processes and colour characteristics during the first year of ageing in oak barrel has allowed the assessment of the ageing ...

Comprehensive Colorimetric Study of Anthocyanic Copigmentation in Model Solutions. Effects of pH and Molar Ratio
(American Chemical Society, 2012)
New colorimetric variables have been defined in the uniform CIELAB color space to assess the quantitative and qualitative color changes induced by copigmentation and their incidence on visual perception. The copigmentation ...

Effects of Salinity Stress on Carotenoids, Anthocyanins, and Color of Diverse Tomato Genotypes
(American Chemical Society, 2011)
One nonanthocyanin-accumulating (Ailsa Craig) and three anthocyanin-accumulating tomato genotypes (Anthocyanin fruit type, Atroviolaceum, and Sun Black) were analyzed to assess differences in their carotenoid and anthocyanin ...
