Abstract
A process for the production of nanocrystals or amorphous nanoparticles of actives (nanomaterials), especially from the peels of grapes. A dispersion of a micrometer-sized material in a solution of surfactant or a steric stabilizer is first provided. The macrosuspension is then stirred for at least 1 minute at a rotational speed above 500 rpm using a rotor-stator mixer. The stirred mixture is passed through a jet stream or piston-gas type high pressure homogenizer. The nanomaterials produced can be incorporated into formulations for use as nutraceutical, nutritional supplement, or as supportive treatment in medical therapy. The active can be derived from the peels of grapes.
