  • Title: Determination of 4-hexylresorcinol in crab meat.
    Author: Smallwood AW, Ranieri TL, Satzger RD.
    Journal: J AOAC Int; 1998; 81(2):488-91. PubMed ID: 9549084.
    Abstract:
    A method is described for determining 4-hexylresorcinol in crab meat. 4-Hexylresorcinol is used to prevent melanosis in shrimp, and the same use has been proposed for crab meat. Because 4-hexylresorcinol may be added illegally to crab meat as a preservative, consumer protection requires that residues of the compound be monitored in crab meat. 4-Hexylresorcinol is extracted from crab meat with acetonitrile. After dilution with water, the extract is passed through a C18 solid-phase extraction column and 4-hexylresorcinol is eluted from the column with ethanol. The compound is determined by reversed-phase liquid chromatography with diode array detection at 206 nm. Limit of quantitation is 1.0 microgram/g. Mean recovery in the range 1-20 micrograms/g is 89%, with a relative standard deviation of 6.3.
