The effects of different stages of apple juice concentrate production on patulin levels were investigated. Patulin was detected in all samples analyzed in concentrations ranging from 56 to 653 mu g/L. Apple paste resulted from milling process had high levels of patulin. The results of this study indicate that it is possible to reduce patulin level in apple juices. After pasteurization, enzymatic treatment, microfiltration and evaporation processes, the mean loss of patulin was 39.6, 28.3, 20.1 and 28.4%, respectively. When apple juices concentrate were diluted from 69 to 12 degrees Brix to consume, patulin content ranged from 15 to 46 mu g/L. Patulin content in all juice samples was lower than the limit of 50 mu g/L considered acceptable by the Codex Alimentarius Commission. But if consider the maximum permitted concentration established for apple products intended for infants and young children by The Commission of the European Communities all samples were found to exceed patulin concentration of 10 mu g/L.
