Although, Patulin and Ochratoxin are produced by the same genera of molds, however, Patulin was the most extensively studied mycotoxins in apple juice and no reports have explored the presence of Ochratoxin A in the apple juice.

Therefore, the objective of this study was to explore the presence of Patulin and Ochratoxin A in apple juice in Saudi Arabian market of Jeddah.

Potato dextrose agar (PDA) was used to detect fungal contamination.

Patulin was determined using HPLC equipped with a UV detector set at 276 nm.

Also, HPLC with fluorescence detector was set at 333 and 420 nm as excitation and emission wavelength, respectively,was used for Ochratoxin A separation.

All samples of apple juice were free from fungi and yeasts.

The Patulin (PAT) was detected in only one type out of 17 types (5.88 %) with a concentration of 152.5 ppb, (305 %) increased compared with the maximum permitted level (50 ppb).

However the occurrence of Ochratoxin A (OTA) in apple juice samples was discovered in 5 types out of 17 types (29.41 %).

The concentration of OTA ranged from 100 to 200 ppb reaching 5–10-folds compared with the permissible limits (20 ppb).
