Thermodynamic study of the non covalent interactions of phytate with xanthine derivatives and histamine in aqueous solution

► Non covalent interactions phytate-xanthine derivatives. ► Stability trend for the log Kq: Phy-Tb > Phy-Tp > Phy-Hm > Phy-Cf. ► ΔH and TΔS parameters of the Phy-Cf complexes at I = 0.5 mol L- 1 in NaCl(aq) by calorimetric titrations.
