Solid-phase extraction method for patulin in apple juice and unfiltered apple juice.

A soild-phase extraction method is described for the determination of patulin in apple juice and unfiltered apple juice.  A portion of the test sample was passed through a macroporous copolymer cartridge and was washed with 1% sodium bicarbonate and then with 1% acetic acid.  Patulin was eluted with 2% acetonitrile in anhydrous ethyl ether and was determined by reversed phase LC with UV detection.  Recoveries ranged from 93 to 104% in test samples spiked at 20 – 100 mg/L.
