For diacylated anthocyanins, π-stacking (vertical) interactions + (horizontal) metal binding modulate color and greatly enhance its stability in neutral solution
The color of food is critical to the and beverage industries, as it influences many properties beyond eye-pleasing visuals including flavor, safety, nutritional value. Blue one rarest colors in nature's palette-especially a cyan blue-giving scientists few sources for natural blue colorants. Finding dye equivalent FD&C No. 1 remains an industry-wide challenge subject several research programs worldwide. Computational simulations large-array spectroscopic techniques were used determine 3D...
Red cabbage (RC) and purple sweet potato (PSP) are naturally rich in acylated cyanidin glycosides that can bind metal ions develop intramolecular π-stacking interactions between the chromophore phenolic acyl residues. In this work, a large set of RC PSP anthocyanins was investigated for its coloring properties presence iron aluminum ions. Although relatively modest, structural differences anthocyanins, i.e., acylation site at external glucose sophorosyl moiety (C2-OH vs. C6-OH PSP)...
High-quality dark chocolates (70% cocoa content) can have shades from light to brown color. This work aimed at revealing compounds that discriminate black and chocolates. From 37 fine chocolate samples years 2019 2020 provided by Valrhona,8 8 were selected. A non-targeted metabolomics study was performed based on ultra-high performance liquid chromatography—high resolution mass spectrometry/mass spectrometry experiments, univariate, multivariate, feature-based molecular networking analyses....
