Abstract

|
4-Hexylresorcinol (4-HR) has been used for prevention of melanosis in shrimp. Recently, 4-HR in EU and other countries was authorized with maximum residue levels of 1∼2 mg/kg but remains unauthorized in Korea. Therefore, the aim of this study was to investigate the effect of 4-HR on melanosis inhibition and residual levels in Korean shrimp according to various concentrations and soaking times. We previously reported that the HPLC-FLD method can be used for detection of 4-HR at maximum levels of 1∼2 mg/kg in shrimp. Our results show that residual levels of 4-HR in peeled and unpeeled shrimps were in the range of 0.86 to 13.46 mg/kg and 0.02 to 2.33 mg/kg, respectively. In addition, 4-HR treatment at concentrations of 10 and 20 mg/L for 72 h were effective for inhibition of melanosis in peeled shrimp compared with unpeeled shrimp. These results provide basic data for the establishment of guidelines and regulation related to 4-HR.
