Patulin content has been evaluated in 754 samples of apple juices bought on Polish retail markets in the years 1993-2003. The samples were analyzed by means of the HPLC technique with UV detector. Patulin was found above the quantification limit (5 microg/l) in more than 22% of the samples. Most of the positive results did not exceed the permitted level of 30 microg/l. However, the level was exceeded in 8 samples i.e. in 1.1% of the analyzed samples.
