A LC method for the determination of patulin was evaluated for a long term survey of patulin in apple juice concentrates. Patulin was separated on a reversed phase C18 LC column with water-acetonitrile (99:1) as the mobile phase and quantified with a photodiode array (PDA) detector. Relatively low amounts of patulin (less than 5 mg/L for single strength juice at 11.2ºBrix) were detected in apple juice concentrates and confirmed by PDA detector. In Turkey, 482 apple juice concentrates produced through 1996-99 were analysed for their patulin contents. Year-to-year variations in patulin levels were statistically significant. Contamination levels tended to decrease through the years 1996-99 and averages 63, 43, 19 and 31 mg/L, respectively. Percentages of concentrates exceeding the maximum permitted concentration of 50 mg/L were 52, 34, 8 and 8% respectively.
