Malachite Green Rapid Test Kit For Aquatic Products, Fish, Shrimp and Seafood

Not just a rapid test supplier — a long-term, globally proven food safety partner.

Fast, reliable screening for Malachite Green (MG), Leucomalachite Green (LMG), Crystal Violet (CV) and Leucocrystal Violet (LCV) in aquaculture and seafood products.

NANKAI Biotech’s Malachite Green Rapid Test Kit delivers accurate front-end detection of prohibited triphenylmethane dye residues, helping seafood exporters, processors, aquaculture farms and inspection teams reduce risk before laboratory confirmation, shipment or market release.

Why Screen for Malachite Green Family Residues? Malachite Green and its metabolites are strictly prohibited in food-producing aquatic animals in most major markets. Early detection is critical to avoid shipment rejections, regulatory penalties, product recalls and brand damage.
