This Technical Specification specifies a method for the determination of canthaxanthin and astaxanthin in fish flesh by high performance liquid chromatography (HPLC). The method can be applied at a range above 0,02 mg/kg. The method should not be applied to the determination of canthaxanthin in poultry tissues, egg yolks and shrimp tissues due to a possible interference of canthaxanthin with cryptoxanthin and xanthophyll esters sometimes present in these matrices.
