Hydrophobic interactions between aroma compounds and beta-Lactoglobulin using NMR and a fluorescent probe

2010

International audience; beta-lactoglobulin (bLg) is known to interact with aroma compounds affecting their release, and hence, their perception. bLg, composed of two hydrophobic binding sites, was used as a simple model food protein to investigate binding mechanisms as a function of ligand nature. Indeed, binding of small ligands to bLg sites is often selective, although some ligands bind to both sites. Interactions between bLg and one ketone, beta-ionone, and one phenol, guaiacol were investigated by combining two techniques: 2D Nuclear Magnetic Resonance for binding site location, and fluorescence using the 6-propionyl-2-(N, N-dimethylamino)naphthalene (PRODAN) probe for surface hydrophob…
