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 ...

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...

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...

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 common pistachio psylla, Agonoscena pistaciae Burckhardt and Lauterer (Hem.: Aphalaridae), is one of the most important pests of pistachio orchards in Iran. Green lacewing, Chrysoperlacarnea, as a general predator found abundantly in Iranian pistachio gardens, loses its performance under the impression of pesticides spraying. Nowadays, considering environmental pollutions,...

We present a consumer-focused perspective on creating communications regarding potentially contaminated foods. It is illustrated with decisions that might have faced US consumers during the 2009 recalls of peanut and pistachio products. The example shows how knowledge about test results and regulatory processes might be made more useful to consumers.

Pistachio hull contains anacardic acids. It is a salicylic acid with side chain either saturated or unsaturated. This work focused on the efficient extraction of acids using solvent. Six aliquots were weighed and extracted hexane, ethyl acetate, mixture H2O/MeOH/HCl. Hexane was most solvent due to its ability dissolve Only one standard used quantify all them since does not affect wavelength gre...

given the strategic remarkable rank of pistachio in non-oil exports, inputs’ management in its production is so important. as the scarcest input in agricultural sector, water is considered to be among the most important inputs of pistachio production.water inadequate supply and limate conditions increase water demand in pistachio growing areas. it is necessary to determine the real value or pri...
