Impact of Lignosulfonates on the Thermodynamic and Kinetic Parameters of Malvidin-3‑O‑glucoside in Aqueous Solutions

The interaction of malvidin-3-O-glucoside (1) and a lignosulfonate was studied by UV–visible spectroscopy, and the results obtained showed the formation of a complex between the negatively charged lignosulfonate and the flavylium cation form (AH+) of this anthocyanin at pH 1. The thermodynamic and k...
