SODIUM TETRAIODODICHLOROFLUORESCEIN - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| scope of use | food pigment red 105 is Japanese food pigment, which is not allowed to be used in China and other countries. |
| Overview | Fluorescein is a common synthetic organic fluorescent compound, which has a very wide range of applications in various fluorescence analysis. The food pigment red 105 is structurally The ammonia atom on the fluorescein benzene ring is the product of the substitution of the surface element. It was discovered as a dye more than 100 years ago, due to its trembling color of the crimson turtle, it is also called Bengal Rose. |
| use | eat red pigment, used in cherries, fish cakes, kelp fish rolls, sausages, cakes, fish birch, etc., the dosage is 5-100ppm, and can also be used as medicine and cosmetic pigment. |
| Production method | Dissolve the refined tetrachloropsin in sodium hydroxide solution, add iodine to carry out iodination reaction, precipitate with hydrochloric acid, then convert it into sodium salt, and further concentrate to obtain the finished product. |
