Definitions

  • two methods have become known:

  • the active ingredient is flocculated together with the hydrocolloid by adjusting the pH to the isoelectric point, then the flocculated material is separated and dried. Dispersing the powdered product obtained then gives an oily suspension.
  • An analogous process using water-immiscible solvents is described in EP 937 412 A.
  • WO 03/102116 describes oily solutions of a carotenoid.
  • the preparation of these oily solutions is carried out by dissolving the carotenoids in an organic solvent, such as N-methylpyrrolidone, in the presence of a lipophilic dispersant and removing the solvent.
  • the resulting powder is then concentrated in a low concentration in an oil, e.g. As fish oil, solved.
  • WO 2006/125591 describes the preparation of an oily carotenoid composition.
  • the carotenoid is dispersed in an oil phase, the dispersion is heated for a short time to dissolve the carotenoid, and the resulting solution is cooled by mixing with further oil having a lower temperature than the oil solution.
  • the oily composition contains only a small amount of carotenoid, i. Large quantities of the composition must be used to achieve the desired effect. The method is therefore not economical.
