Aflatoxins are secondary metabolites produced by Aspergillus flavus, A. parasiticus, A. tamari, A. bombycis and A. nomius species. Relative humidity (RH) is one of the most important parameters influencing the development of aflatoxins in pistachio orchards by Aspergillus species. The type of irrigation system affects density and frequency of the Aspergillus species in the soil. In the current ...

pistachio nuts are the major non-oil export agricultural commodity in iran. the existence of empty shells among the shells with kernels reduces the quality of the nuts and, consequently, their market value. in pistachio processing plants, empty shells are generally separated from shells with kernels by the flotation method. but this method is not precise and may encourage the growth of fungi in...

Pistachio butter (semi solid paste), which is made from roasted pistachio kernels, is an appropriate alternative to work on because of its high nutritional and economical values. In this study, timedependent flow properties of pistachio butter were determined at two different temperatures (25˚C and 45˚C) for five different formulations (with different levels of emulsifying agents). Forward a...

Pistachio (Pistacia vera L.; Anacardiaceae) is native of aride zones of Central and West Asia and distributed throughout the Mediterranean basin. In Italy, a pistachio cultivar of high quality is typical of Bronte (Sicily), an area around the Etna volcano, where the lava land and climate allow the production of a nut with intense green colour and aromatic taste, very appreciated in internationa...

In order to study on some of pistachio cultivars’ contamination of Khorasan-e-Razavi province,eight cultivars of pistachio kernels were collected from the pistachio production areas of this province. Using serial dilution method, 10 grams of ground pistachio was moved to 90 ml water peptone and continuous dilutions 10-1, 10-2 were prepared. Then 0.1 ml from each dilution was inoculated in three...

Due to low consumer acceptance and the possibility of immature kernels, closed‐shell pistachio nuts should be separated from open‐shell nuts before reaching the consumer. A system using impact acoustics as a means of classifying closed-shell nuts from open-shell nuts has already been shown to be feasible and have better discrimination performance than a mechanical system.The accuracy of an impa...
