Abstract
In order to compare aflatoxin contamination in different pistachio processing stages, this study was done in a completely randomized design with 6 replicates during 2003-2004 in the Pistachio Research Institute.
Treatments were: a) very small screened nuts; b) stained nuts; c) re-hulled pistachio nuts; and d) final pistachio.
Aflatoxin contents in samples of pistachio were determinated with HPLC. Analysis of variance revealed that there was a significant difference between different parts of the processing procedures.
The mean contamination in re-hulled pistachio nuts, stained nuts, very small screened nuts and final pistachio were 286, 210, 140, 1.04 ppb, respectively.
Results indicated that it is necessary not to mix re-hulled pistachio nuts with pistachios, which hulled easily on first stage, and separating stained and very small nuts to decrease aflatoxin in final pistachio.
