Aflatoxin variability in pistachios.

Fresh pistachio kernels were inoculated with Aspergillus flavus and incubated 7 or 10 days.  Hulled, shelled kernels were either left intact or wounded prior to inoculation.  Wounded kernels, with or without the seed coat, were readily colonised by A. flavus and after 10 days contained 37 times more aflatoxin than similarly treated unwounded kernels.  Intact kernels with seed coats had limited fungal colonisation and low aflatoxin concentrations compared with their wounded counterparts.  Despite substantial fungal colonisation of wounded hulls, aflatoxin was not detected in hulls.  Aflatoxin levels were significantly lower in wounded kernels with hulls than in kernels of hulled pistachios.  Both the seed coat and a water soluble extract of hulls suppressed aflatoxin production by A. flavus.
