Analysis of food dyes E 110, E 111, and E 124 in fish samples by ion pair partition HPLC.
The isomeric food dyes E 110 and E 111 can be separated by ion pair partition HPLC on reversed-phase columns. The isomer E 111 - no longer permitted in Germany - can thus be determined in dye and food samples. The determination of E 110, E 111, and E 124 in fish samples (canned saithe) is described.
