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 ...

Effect of Addition of Overripe Seeds from White Grape by-products During Red Wine Fermentation on Wine Colour and Phenolic Composition
(Elsevier, 2017)
The effect of the fermentative addition of overripe seeds by-product (Pedro Ximénez white grapes, 3 g/L) on the phenolic composition and colour of red wines was studied by rapid resolution liquid chromatography (RRLC-MS) ...

Assessment of the color modulation and stability of naturally copigmented anthocyanin-grape colorants with different levels of purification
(Elsevier Ltd, 2018-04)
Grape skins or their by-products from wine production are rich sources of anthocyanins and various colorless phenolics, depending on the grape variety. Phenolics have strong antioxidant and anthocyanin stabilizing properties ...

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), ...

Copigmentation Potential of Overripe Seeds from Sun-dried White Grapes on Anthocyanins Colour and Stability by Differential Colorimetry
(Wiley-Blackwell, 2020)
Overripe seeds are wine by-products from grapes submitted to postharvest sun drying, which induce phenolic biosynthesis and polymerisation. Overripe seeds from Pedro Ximénez (PX) and Moscatel (MO) sun-dried grapes were ...

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 ...
