Abstract

There is scarce data on the mycotoxin profile in retailed fruit juices in Nigeria. Thirty-five industriallyprocessed
fruit juice samples randomly purchased from retailers in Ogun state, Nigeria, were analysed
for the presence of > 650 toxic fungal and plant metabolites using a liquid chromatography tandem
mass spectrometric method. Only 18 metabolites, including 3-nitropropionic acid, alternariol methylether
and emodin, but excluding citrinin, fumonisin B2, ochratoxin A and patulin, were detected in
trace levels in at least one juice sample. Amygdalin, a plant cyanogen, was quantified (2.05–359 ?g/L)
in 40% of the samples. Although the levels of mycotoxins and toxic plant metabolites found in the
juice may be relatively low, daily consumption of juices containing such low levels may contribute to
dietary exposures to these natural chemical contaminants in consumers. Fruit juice processors should
be encouraged to adhere strictly to good manufacturing practices in order to keep mycotoxins away
from the final products.
