The new CPE-based LCMS method was used for the analysis of approved water soluble (Sunset yellow, Allura red, Tartrazine and Erythrosine) and banned fat soluble (Sudan I-IV, Sudan red G, Sudan red B, Sudan red 7B, Sudan black B, Metanil yellow and Rhodaminc B) azo colors.

Metanil Yellow (2.91 minutes) and Sulforhodamine B (2.96 minutes) are not baseline-resolved; however, this is not considered a problem because Sulforhodamine B is not commonly used as a dye in black pen ink formulations, but Sulforhodamine B has been observed for ink-jet printer inks analyzed with the same experimental setup.

However, in actual practice, other nonpermitted synthetic dyes like auramine, metanil yellow, lead chromate, rhodamine, sudan-3 and 4, orange-2 and Malachite green, which pose serious health hazards, as they are mutagenic and potential carcinogens, are being used as food colours in the market.

Hazards of food colours

Ovarian tissue was initially fixed in 10% buffered formalin; a section of tissue was then transferred to ethanol, embedded in glycol methacrylate, sectioned along the transverse plane, stained with the periodic acid-Schiff (PAS) reaction, iron-hematoxylin, and counterstained with metanil yellow (Quintero-Hunter et al., 1991).

Gonad samples were prepared for histological examination with a modification of the periodic acid Schiff's (PAS) stain for glycol-methacrylate sections and with Weigert's iron-hematoxylin as a nuclear stain and metanil yellow as a counterstain (Quintero-Hunter et al., 1991).
