  • Patent number: 5507991
    Abstract: A solution of substantially pure, chemically synthesized food dye is converted to a dustless and abrasion-resistant granular composition of high physical integrity which dissolves readily when intended for use. The conversion is accomplished by subjecting the dye to sequential processing operations including spray drying, mixture with water and extrusion under controlled rate and pressure. Optional, albeit preferred additional procedures include drying the product under controlled temperature following extrusion and vibration sifting the product following drying to obtain granules of approximate uniform size prefatory to packaging.
