  • Purification process for improving total yield of curcuminoid colouring agent
    Publication number: 20030180401
    Abstract: The present invention pertains to a process of improving the total yield of curcuminoids from curcuminoid-containing material. More specifically, there is provided a process wherein a second residue, previously considered a waste resulting from a crystallisation step of a curcuminoid-containing phase, is made useful by improving the colouring properties of this second residue by extraction with hexane and/or methanol at ambient temperature. The pro??cess improves the total yield of curcuminoids by 30-40%.

  • Process for the preparation of an organic pigment dispersion
    Patent number: 4765841
    Abstract: An organic pigment dispersion in a non-aqueous medium is prepared directly from an aqueous slurry containing 0.1-20% by weight of the pigment by mixing the aqueous slurry with the non-aqueous medium under vigorous agitation and subsequently isolating the organic pigment dispersion from the residual aqueous phase.A substantial part of water in the resulting pigment dispersion can be removed by passing the organic pigment dispersion in the non-aqueous medium over a series of surfaces, the surface material thereof having different affinity for water and the non-aqueous medium, respectively, and then removing water and pigment dispersion in the non-aqueous medium, respectively, from respective surfaces.
