In this paper an intelligent separation system, based on artificial neural networks (ANNs), for classifying four different varieties of Iranian pistachio nuts, namely, Kaleghouchi (Ka), Akbari (Ak), Badami (Ba) and Ahmadagaee (Ah) is presented. To develop the ANN models a total of 3200 pistachio sound signals, 800 samples for each variety, were recorded. Features of pistachio nut varieties were...

Different methods have been applied to recycle pistachio’s green hulls, the most important of which are siloing and drying pistachio hulls (using industrial dryers). In both methods, hulls should lose their initial moisture content, which constitutes a considerable portion of their weight. The high moisture content takes more time and energy during the drying process. The initial dewateringof h...

abstract during 2007 and 2008, a survey on species diversity of acari associated with pistachio trees and seasonal dynamics of the dominant injurious species was conducted in mahvelat region for the first time. 8 varieties of pistachio including akbari, owhadi, badami, barg siah, ghermez, kalah ghochi, germeh and momtaz, commonly grown in the region were compared in terms of infestation to the ...

pistachio has a special ranking among iranian agricultural products. iran is known as the largest producer and exporter of pistachio in the world. agricultural products are imposed under different thermal treatments during storage and processing. designing all these processes requires thermal parameters of the products such as specific heat capacity. regarding the importance of pistachio proces...

mechanical properties of non-split pistachio nuts are among the lada required for the design of equipment needed for processing of the nut. unsplit pistachio nut samples were uniaxially loaded to determine the nut’s needed splitting force and energy, as well as poisson’s ratio and young’s modulus of elasticity. the tests were carried out at four moisture contents (5, 10, 15 and 20% wb), under f...

to study the chemical composition and qualitative comparison of the pistachio by-products and the effect of pistachio hull tannin on its digestibility and gas production, four experiments were carried out. in the first experiment, nutrient composition, phenolic and tannin components of the ohadi, kaleghuchi and white varieties of pistachio by-product from dehulling process were measured. pistac...

the genetic diversity of a large number of pistachio genotypes grown in iran is not exactly known. most of the studies on genetic diversity of iranian pistachio varieties are based on morphological characteristics or isozyme markers. in the present study, the genetic diversity of selected pistachio cultivars along with some wild species were evaluated by amplified fragment length polymorphism (...
