Techniques for localisation of konjac glucomannan in model milk protein-polysaccharide mixed systems: Physicochemical and microscopic investigations

► Covalent conjugation of konjac with fluorescein isothyocyanate affects structural properties of konjac. ► The lectin concanavalin A binds to konjac. ► Konjac-fluorescein isothyocyanate conjugate: suitable for localisation of konjac. ► Konjac-concanavalin A complex: not suitable for localisation of konjac.
