Aplicación de la colorimetría triestímulo para evaluar la estabilidad de extractos ricos en antocianinas de frutas tropicales colombianas
(Facultad de Química Farmacéutica. Universidad de Antioquía, 2012)
El uso de la colorimetría triestímulo permitió evaluar la estabilidad del color de los extractos enriquecidos en antocianinas (AREs) de cuatro frutas tropicales Colombianas: motilón, coral, uva de árbol y mora pequeña, a ...

Application of differential colorimetry to evaluate anthocyanin-flavonol-flavanol ternary copigmentation interactions in model solutions
(American Chemical Society, 2015)
The combined effect of anthocyanin−flavanol−flavonol ternary interactions on the colorimetric and chemical stability of malvidin-3-glucoside has been studied. Model solutions with fixed malvidin-3-glucoside/(+)-catechin ...

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 ...

Optimisation of an Oak Chips-grape Mix Maceration Process. Influence of Chip Dose and Maceration Time
(Elsevier, 2016)
Oak chips-related phenolics are able to modify the composition of red wine and modulate the colour stability. In this study, the effect of two maceration techniques, traditional and oak chips-grape mix process, on the ...

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 ...
