A dye for coloring foods, nutritional supplements, cosmetic or pharmaceutical products, comprising:
- at least one pigment in the form of a water-insoluble sulfate, carbonate or phosphate of at least one alkaline earth metal, which is selected from the group consisting of
- magnesium phosphate,
- calcium phosphate,
- magnesium carbonate, and
- calcium sulfate anhydrite having a mean particle size (d[4,3]) from 1.0 to 5.0 μm.
A method for whitening foods, nutritional supplements, cosmetic or pharmaceutical products, comprising:
- mixing a foodstuff, nutritional supplement, cosmetic product or pharmaceutical product with a dye comprising
- at least one pigment in the form of a water-insoluble sulfate, carbonate, or phosphate of at least one alkaline earth metal, which is selected from the group consisting of
- magnesium phosphate,
- calcium phosphate,
- magnesium carbonate, and
- calcium sulfate anhydrite having a mean particle size (d[4,3]) from 1.0 to 5.0 μm.
A method for coloring foods, nutritional supplements, cosmetic or pharmaceutical products, comprising:
- mixing a foodstuff, nutritional supplement, cosmetic product or pharmaceutical product with a dye comprising
- at least one pigment in the form of a water-insoluble sulfate, carbonate, or phosphate of at least one alkaline earth metal, which is selected from the group consisting of
- magnesium phosphate,
- calcium phosphate,
- magnesium carbonate, and
- calcium sulfate anhydrite
- with the anhydrite having a mean particle size (d[4,3]) from 1.0 to 5.0 μm,
- wherein a suspension of the dye in an aqueous solution of 7% by weight of sugar at pH 3 has a turbidity which is 2 to 5-times higher than a pigment mixture of 95% by weight of tricalcium phosphate and 5% by weight of calcium carbonate or of 85% by weight of tricalcium phosphate and 15% by weight of calcium carbonate.
