Estimation of malachite-green residues in edible fish. 3. Total malachite-green including the leuko-form

Deutsche Lebensmittel Rundschau 87(11): 350-353

Estimation of malachite-green residues in edible fish. 3. Total malachite-green including the leuko-form

A HPLC method is described for estimating residues of triphenylmethane dyes like malachite green (C. I. 42000) and crystal violet (C. I. 42555) and their leuko-forms in edible fish. The method is used to control the zero tolerance of 0.01 mg/kg for total malachite green and leuco malachite green in fish established in Germany in 1988.
