Patulin and its dietary intake by fruit juice consumption in Iran.

A survey was conducted to determine levels and dietary intake of patulin (PAT) from fruit juices consumed in Iran. PAT content was determined using high performance liquid chromatography-diode array detection in 161 samples of fruit juices including apple, pineapple, pear, peach, pomegranate and white and red grape juices. Results revealed the presence of PAT in 16.1% of the samples examined, ranging from 5 to 190.7 µg/kg. Average and median PAT content in positive samples was 34.5 and 18.5 µg/kg, respectively. PAT concentration in 2.5% of the samples was higher than the maximum limit as set by European regulations for PAT in fruit products (50 µg/kg). Estimated daily intake of PAT by fruit juice was 16.4, 45.9 and 74.6 ng/kg bw/day for Iranian adults, children and babies, respectively. The results of this study showed that PAT does not seem to be a problem in fruit-based drinks commercialised in Iran, except for apple juice.
