A metabolite of Gentian Violet in seafood products | [Definition]
ChEBI: Leucocrystal Violet is a benzenoid aromatic compound. | [Biological Activity]
Leucocrystal Violet (LCV) is a cationic triarylmethane dye. LCV is a reduced form of gentian violet (crystal violet) and thusit is colorless. It has an affinity for both cellulosic and proteinaceous materials. LCV and hydrogen peroxide react with the hemoglobin in blood and turn the blood impression to purple/violet color. Thereforethe dye is widely used to stain blood residue on both porous and non-porous materials. |
