A process for preparing a composition comprising zein, BaSO4, Al and a solvent, the process comprising:
- (a) providing a solvent comprising an organic solvent including alcohol and/or water;
- (b) mixing zein with a first part of the solvent of step (a) to obtain varnish zein;
- (c) mixing Al pellets with a second part of the solvent of step (a) to obtain a dough;
- (d) mixing the varnish zein obtained at step (b), BaSO4, Al, the dough obtained at step (c) and a third part of the solvent of step (a) to obtain a concentrated mixture;
- and
- (e) mixing the concentrated mixture obtained at step (d) with a fourth part of the solvent of step (a) to obtain the composition.
