Background: Pistachio is a plant that has long been cultivated in different parts of Iran. Pistachios are very nutritious and contain vitamins E and B, flavonoids, antioxidants, and carotenoids. Since the pistachio is effective in the treatment of some neurological disorders and is indigenous to Iran and considering the substantial use of this nut, it is necessary to investigate its effects on ...

Investigation and Comparison of Slenderness Coefficient Old Persian Oak Wild Pistachio Trees in Different Site Conditions the Middle Zagros

Roasting of whole-kernels is an important step in the production of pistachio paste. The effect of hot air roasting temperatures (90-190°C) and times (5-65 min) on the hardness, moisture content and colour attributes (‘L’, ‘a’ and ‘b’ values and yellowness index) of both whole-kernel and ground-state were investigated using response surface methodology (RSM). Increases in roasting temperature a...

The essential oils of the fruits and the leaves of pistachio (Pistacia vera L.) were analyzed by GC and GC/MS. Fresh unripe pistachio fruits were richer in essential oil (0.5%, w/w) than the leaves (0.1%, w/w). Twenty one compounds were identified in the essential oil of the fruits and the major components were (+)-alpha-pinene (54.6%) and terpinolene (31.2%). The enantiomeric ratio of the majo...

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...

We completely characterize deterministic strategy-proof and group strategy-proof mechanisms on singlesinked public policy domain. The single-sinked domain can be used to model any allocation problem where a single output must be chosen in an interval with the assumption that agents’ preferences have a single most loathful point (the sink) in the interval, and the preferences are increasing as o...

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 ...

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...
