  • Process for the preparation of a water dispersible carotenoid preparation in powder form
    Patent number: 5811609
    Abstract: A powdered water-dispersible carotenoid preparation in the form of discrete carotenoid microparticles is prepared by milling a carotenoid in an aqueous medium in the presence of a hydrocolloid so as to form a suspension, heating the suspension thus formed to a sufficiently high temperature to cause a total or partial melting of the carotenoid and cooling, finely dividing and drying the suspension to form a powder.

  • Process of preparing a water dispersible hydrophobic or aerophilic solid
    Patent number: 5460823
    Abstract: A process for producing hydrophobic or aerophobic solids having a particle size not exceeding 10 .mu.m, which solids can be dispersed in water in the form of discrete microparticles. In the process the solids are milled in an aqueous medium in the presence of a hydrocolloid to obtain a suspension containing suspended particles having an average particle size not exceeding 10 .mu.m. The suspension is then finely divided and dried to form a powder.
