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...

Pistachio is one of the most important agricultural crops of Iran. It is a nut from Anacardiacea family and its domesticated species is called Pistacia vera L. Regarding to pistachio importance and usage and by the expanding of pistachio cultivate, it is necessary to improve agricultural situation and by establishing well equipped processing and packaging units near the farms, it is possible to...

Twenty isolates of Trichoderma harzianum wereisolated from the rhizosphere of healthy pistachio plants from different localities of Kerman Province, Iran.Five isolates with high antagonistic activity in in vitro assays against Verticillium dahliae (the causal agent of pistachio wilt), were investigated for their effect on the defense enzymes, peroxidase (PO), phenyl alanine-ammonia lyase (PAL) ...

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...

this study was conducted in two separate experiments. four rumen-cannulated sheep were allocated in the first experiment to evaluate date by-product (dbp) and date seed (ds) nutrients degradation in rumen. in experiment two eighteen fattening lambs were allocated in three different treatments (6 animals/treatment) to evaluate dbp effects on animal performance and nutrients’ digestibility. three...

Pistachio is one of the most important horticultural products of Iran with special economic importance. In average 70% of Iran pistachio are exported. Aflatoxin is secondary metabolites of fungus such as Aspergillus flavus and A. parasiticus. If favorite condition is prepared for stabilization of fungi spores producing Aflatoxin, the first pistachio contamination to Aflatoxin occurs in orchard....
