摘要：

An analytical method for the determination of specific migration levels of phenolic antioxidants and one phosphite antioxidant in the aqueous food simulants established by European legislation has been developed. This method involves solid-phase extraction (SPE) of the antioxidants with silica C-18 cartridge and their determination by liquid chromatography (LC) with diode-array detection. The achieved results in the studies of elution volume determination, breakthrough volume and accuracy are showed. Recoveries in the range of 78-104% and a relative standard deviation between 2.0 and 7.7% have been achieved. (c) 2005 Elsevier B.V. All rights reserved.
