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...

Pistachio nut has high nutritional value. The fat and protein are the common part of pistachio. Major part (about 88%) of the fat content of pistachio includes unsaturated fatty acids. Unsaturated fatty acids are known to have positive effects on human health like preventing to heart diseases. This research has evaluated protein, fat and fatty acids content of some commercial pistachio cultivar...

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...

T he U.S. pistachio industry, which is located almost exclusively in Califor-nia, has experienced phenomenal growth over the past thirty years. The value of U.S. production of pistachios grew from nearly zero in 1976 to $333 million by 2002. The U.S. share of the rapidly growing global pistachio industry has also increased. Outside California, the main pistachio growing region is the Middle Eas...

Pear psylla, Cacopsylla pyricola (Förster) (Homoptera: Psyllidae), is a major pest of commercial pears in North America and Europe. Olfactometer trials have shown that males of both the summer and winter morphotype are attracted to female-infested host material. Additional work with the summer morphotype has shown that males are attracted to females even in the absence of the host plant, which ...

Pistachio as a strategic product has a particular position among Iranian productions and is one of the most important non-oil exports after carpet. In this study, after primary processing such as dehulling, washing, drying and roasting, pistachio nuts were packed in four different atmospheres including N2, CO2, vacuum and ambient air. Storage temperatures were 20 C and 40 C for a 12 month perio...

Roasting is the most common way for pistachio nuts processing, and the purpose of that was to increase the products total acceptability. Purpose of this study was to investigate the effect of temperature (90, 120 and 150°C), time (20, 35 and 50 min), and roasting air velocity (0.5, 1.5 and 2.5 m/s) on geometrical attributes of pistachio nuts and kernels including principle dimensions, shape fac...

Due to low consumer acceptance and possibility of having immature kernels, closed-shell pistachio nuts have to be separated from open-shell pistachio nuts. The feasibility of a system using non-contact impact acoustics as a means for classifying closed-shell nuts from open-shell nuts has already been shown with better discrimination performance than a mechanical system. The accuracy of an impac...

In this study, the treatment of pistachio nuts by Bacillus subtilis UTBSP1, a promising isolate to degrade aflatoxin B1 (AFB1), caused to reduce the growth of Aspergillus flavus R5 and AFB1 content on pistachio nuts. Fluorescence probes revealed that the cell free supernatant fluid from UTBSP1 affects spore viability considerably. Using high-performance liquid chromatographic (HPLC) method, 10 ...
