Automated processing and classiication of real-time X-ray images of randomly oriented touching pistachio nuts is discussed. The ultimate objective is the development of a system for automated non-invasive detection of defective product items on a conveyor belt. This approach involves two main steps: preprocessing and classiication. Preprocessing locates individual items and segments ones that t...

This paper highlights the capability of artificial neural networks for predicting shelf life of milky white dessert jeweled with pistachio. Linear layer (train) and generalized regression models were developed and compared with each other. Neurons in each hidden layers varied from 1 to 30. Data samples were divided into two sets, i.e., 80% of data samples were used for training and 20% for vali...

Several agro-industrial wastes (as chestnut and pistachio shells, grass, leaf fruit, vine leaf, and, red and white grape stems) were evaluated to ferulic acid extraction. The chemical analysis of these raw materials shows a high content of xylan in pistachio shells (33%), following the biorefinery concept, this fraction can be used in xylitol manufacture. The lignocellulosic materials were subm...

objectives: considering the increasing prevalence of depression in modern societies and the positive effects of omega-3 polyunsaturated fatty acids on depression, this study aims to investigate the omega-3 and omega-6 content of various foodstuffs, prescribed or prohibited by iranian traditional medicine (itm). materials and methods: firstly, reliable sources of iranian traditional medicine wer...

Can farmers change micro-climates around their crops as an adaptation to climate change? We present a novel adaptation technique for pistachio growers in California, meant to deal with warm winters. A kaolin clay mud is sprayed on dormant trees, blocking sunlight and lowering tree bud temperatures, preventing adverse yield effects of low chill. Climate predictions for California suggest that wi...

The effect of different air temperatures (40, 50, 60 and 70°C), air velocities (1 and 2 m/s) and bed depth (monolayer, 3 and 5 cm) on drying kinetics and lipid quality (peroxide value and free fatty acids) of a variety of Persian Pistachio nuts (Abasali variety) were studied. Additionally, effective diffusivity (D ) was determined eff by using Fick’s second law varied from 7.061×10 to 2.105×10 ...

background: pistachio is one of the main nutrients, not only as a strategic crop but also as a main type of nut, in iranians’ food cycle. the aim of this study was to measure the relative safety of iranian pistachio based on the standard pesticide’s residue limits, which should be monitored and assessed in the cultivation of pistachio in order to confirm its public health. methods: fifty sample...

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 this study, the situation of Iran, U.S and Turkey's Pistachio export is investigated. to this purpose, Revealed Comparative Advantage (RCA) Index is calculated based on Agricultural and total economy export, separately, then forecasted by using Auto- Regressive Integrated Moving Average (ARIMA) approached, for 2008-2013. The results show that considering both commodity baskets, Turkey and Ir...
