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...

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...

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

The common pistachio psylla, Agonoscena pistaciae (Homoptera: Psyllidae) is known as the key pest of pistachio trees in Iran. This study was carried out during three years to test the effect of dish washing detergent (Rika ® ) against this pest in a randomized complete block design with five treatments and four replicates. The treatments were including: 13500ml dish washing detergent per 1000 l...

Due to low consumer acceptance and the possibility of immature kernels, closed‐shell pistachio nuts should be separated from open‐shell nuts before reaching the consumer. A system using impact acoustics as a means of classifying closed-shell nuts from open-shell nuts has already been shown to be feasible and have better discrimination performance than a mechanical system.The accuracy of an impa...
