BACKGROUND Nuts are one of the main consumed snacks worldwide and also have an important role among Iranian's food habits. Natural contamination of nuts with aflatoxin is unavoidable and causes a special challenge for nuts safety and quality. OBJECTIVES The purpose of this research was to study the aflatoxin contamination in commercially-available nuts (pistachio, walnut and peanut) in the ma...

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...

Aflatoxins are potent mycotoxins produced by fungi in Aspergillus section flavi. The toxic effect of aflatoxins on humans and other animals is well known (7); thus, many countries regulate the quantity of aflatoxins allowed in foods and feeds (17). Aspergillus flavus Link:Fr. infects many oilseed crops and is frequently, as with cottonseed, the primary cause of aflatoxin contamination (13). Whe...

Pistachio is a nut with high consumption that can be affected by aflatoxin contamination. Regarding influence of this fungus on global trade, broad studies in this area seem to be necessary. In this research, pistachio nuts were coated with methyl cellulose at different concentrations of 0.1%, 0.5%, 1%, and 2% by immersion method. Samples were stored in an incubator (25°C) for 4 months. Imaging...

Nuts are among the crops that can be contaminated by aflatoxins (AFs), mycotoxins mainly produced by A. flavus and A. parasiticus. These fungi are well adapted to tropical and sub-tropical areas and tend to contaminate damaged or stressed crops. Both peanuts and pistachio nuts are well protected by their shells during the growing season, but damage caused by parasites, or early split in pistach...

Aflatoxins are highly toxic compounds that are produced as secondary metabolites by some Aspergillus and Emericella species. Despite huge progress on aflatoxin research during the past 50 years, we have witnessed many cases of food contamination with aflatoxins all over the world. Aflatoxins have mutagenic and carcinogenic effects and they are capable of inducing hepatocellular carcinoma in hum...

In this study, we investigated the binding ability of Saccharomayces cerevisiae to aflatoxin in pistachio nuts. The obtained results indicate that S. cerevisiae has an aflatoxin surface binding ability of 40% and 70% (with initial aflatoxin concentrations of 10 and 20 ppb) in the exponential phase. Acid treatments increase this ability to approximately 60% and 73% for the two concentrations of ...
