Development and validation of an analytical method for the determination of 4-hexylresorcinol in food

초록

This study presents a method validation for extraction and quantitative analysis of 4-hexylresorcinol residues in shrimp and crab meat using HPLC-FLD. We were focused on the collaboratively analysis of each shrimp and crab meat samples, and developed LC-MS/MS method for the correct confirmation of the identity of compound. Validation parameters; selectivity, linearity, LOD, LOQ accuracy, precision, and measurement of uncertainty were attained. The measurement of uncertainty was based on the precision study, data related to the performance of the analytical process and quantification of 4-hexylresorcinol. For HPLC-FLD analysis, the recoveries of 4-hexylresorcinol from spiked samples at levels of 0.2-10.0 ppm ranged from 92.54% to 97.67% with RSDs between 0.07% and 1.88%. According to these results, the method has been proven to be appropriate for extraction and determination of 4-hexylresorcinol, and can be used to maintain the safety of shrimp and crab products containing 4-hexylresorcinol residues.
