Composition and evolution of oligomeric proanthocyanidin–malvidin glycoside adducts in commercial red wines

Food Chemistry, 2021
Studies regarding composition and evolution of oligomeric proanthocyanidin-anthocyanin adducts in red wines have often focused only on a limited number of small dimers. Now, a group-specific liquid chromatography-tandem mass spectrometry method was utilized to measure two-dimensional (2D) chromatographic fingerprints of three different types of ...

Physicochemical, Bioactive, and Clinical Evaluation of Blueberry‐Enriched Kombucha as a Functional Beverage

Journal of Food Science, Volume 91, Issue 9, September 2026.
ABSTRACT This study aimed to develop a blueberry‐flavored kombucha and evaluate its functional properties and effects on human intestinal health. The beverage was produced from green tea and sucrose, fermented with a symbiotic culture of bacteria and yeasts (SCOBY), followed by the addition of blueberry syrup and a second fermentation stage.

Fluorescence spectra and decays of malvidin 3,5-diglucoside in aqueous solutions

Journal of Photochemistry and Photobiology A: Chemistry, 1990
Abstract The fluorescence properties of malvidin 3,5-diglucoside in aqueous solutions at various pH values were investigated using steady state and time-resolved fluorescence techniques. Fluorescence emission bands were assigned to the flavylium cation (AH + ) (λ max = 620 nm), hemiacetal (B) (λ max = 370 nm), chalcone (C) (λ max = 435 nm ...

The effect of foliar fertilizing on ecological optimization of the application of fungicides on the productivity and phenolic complex composition of grapes

BIO Web of Conferences, 2019
One of the ways to reduce the pesticidal burden in mature ampelocenoses is the use of foliar bio-preparations of multifunctional action. We studied the influence of growth bioregulators “Albit” and “Mival-Agro” at reduced by 25–50% fungicidal load on ...

Comparing the Chemistry of Malvidin-3-O-glucoside and Malvidin-3,5-O-diglucoside Networks: A Holistic Approach to the Acidic and Basic Paradigms with Implications in Biological Studies

Journal of Agricultural and Food Chemistry
The kinetics, thermodynamics, and degradation of malvidin mono- and diglucosides were studied following a holistic approach by extending to the basic medium. In acidic conditions, the reversible kinetics of the flavylium cation toward the equilibrium is controlled by the hydration and cis-trans isomerization steps, while in the basic medium, the OH ...

Chemical Characterization of an Encapsulated Red Wine Powder and Its Effects on Neuronal Cells

Molecules, 2018
Red wine polyphenols are known for their implications for human health protection, although they suffer from high instability. For this reason, a red wine powder was prepared by freeze-drying encapsulation in maltodextrin/arabic gum matrix, and its ...
