Electrosynthesis as well as coacervation at pH 3.2 were employed for preparation of complexes of xanthan gum with ovalbumin. Complexes contained by —10% of ovalbumin more than blends from which the complexes were prepared. Preparation method had a minor effect on the properties of the prepared complexes. Complexes from coacervation were slightly more thermally stable than complexes prepared electrosyn- thetically. Xanthan gum and ovalbumin were combined with one another to form a complex of the stoichiometric ratio close to 1:1. Excessive amount of ovalbumin, if present in the reaction mixture, sorbed on this complex. The obtained products were weak electrostatic complexes with involvement of non-polar interactions.
