Structuration mechanism of β-lactoglobulin - acacia gum assemblies in presence of quercetin

► Mechanism of BLG-TAG assemblies in presence of quercetin. ► Provide information about thermodynamic mechanisms of TAG-BLG binding processes. ► Isothermal titration calorimetry combining with complementary methods on titration mode. ► Protein conformational change and formation of BLG-quercetin complexes stabilized by hydrophobic associations. ► Quercetin increases BLG-TAG binding through electrostatic and hydrophobic interactions.
