Iran is the biggest pistachio producer and exporter in the world. Surely, one of the most problems of pistachio industry is Aflatoxin contamination in recent years that treated exportation this valuable crop. This research was done in order to evaluate Aflatoxin contamination in indehiscence and mechanical splitting pistachios of Ouhadi cultivars in Rafsanjan region. Treatments of this research...

Pistachio is one of the most important horticultural products of Iran with special economic importance. In average 70% of Iran pistachio are exported. Aflatoxin is secondary metabolites of fungus such as Aspergillus flavus and A. parasiticus. If favorite condition is prepared for stabilization of fungi spores producing Aflatoxin, the first pistachio contamination to Aflatoxin occurs in orchard....

In order to study the contamination of Aspergillus flavus and aflatoxin production in pistachio cultivars in the Semnan province, eight cultivars of pistachio were collected from major pistachio growing areas. Using the serial dilution method, ground pistachio kernels were inoculated on plates containing AFPA medium and incubated at 28° C. This experiment was performed using three replications ...

In pistachio nuts, aflatoxin is mainly concentrated in the green hull-cracked nuts in the orchard even prior to harvest. However, during the hull-removal process, the hulls of all nuts including the cracked, identifiable nuts are removed causing an important characterization criterion of the contaminated nuts, to be lost. This, in turn, makes it harder to detect the contaminated nuts. However, ...

Doster, M. A., Cotty, P. J., and Michailides, T. J. 2014. Evaluation of the atoxigenic Aspergillus flavus strain AF36 in pistachio orchards. Plant Dis. 98:948-956. The atoxigenic strain Aspergillus flavus AF36, which has been extensively used as a biocontrol agent in commercial corn and cotton fields to reduce aflatoxin contamination, was applied in research pistachio orchards from 2002 to 2005...

Aflatoxins, carcinogenic toxins produced by Aspergillus fungi, contaminate maize, peanuts, and tree nuts in many regions of the world. Pistachios are the main source of human dietary aflatoxins from tree nuts worldwide. Over 120 countries have regulations for maximum allowable aflatoxin levels in food commodities. We developed social network models to analyze the association between nations' af...

Many studies have shown that mycotoxin contamination of agricultural products is a challenge for individual's health especially in developing countries. Improper production and storage of foods, prepare conditions for aflatoxin production in crops, especially rice, wheat, pistachio, walnut, almond, etc which are the main sources of foods for people. Feeding livestock by contaminated bread is an...

Nowadays, the separation of pistachios which seem to have aflatoxin is done according to their organoleptic physical qualities like color and etc. As these methods are not  fully practical, and there is always a possibility of error and also the conditions like the wrong time harvest, the transportation of picked pistachios, the delay on the processing cause some contaminations in pistachios wh...

Study the effect of fruit cultivar (intact, early split, irregular crack) on (Akbari, Abbasali, Khanjari) cultivars in Damghan city to Aspergillus Flavus fungus and effect of harvest time in early split pistachio in 1389, sampling from orchards has been performed. Samples after grinding by dilute cultivating in a specific AFPA medium bottles in a completely randomized model were three times rec...
