In this paper, the effect of infrared (IR) roasting conditions on Aflatoxins and total counts of two types of Iranian pistachio kernels, long and round, was studied. The optimized roasting conditions, 70 V for round pistachios and 90 V for long pistachios with 10 cm distance from IR source were used. Naturally Aflatoxin-contaminated kernels were supplied and roasted. Microbiological an...
abstract in order to evaluate the effect of testa on reduction of fungal growth and aflatoxin b1 producthon, ten cultivars of pistachio were collected from different parts of pistachio belt i-e rafsanjan, damghan and ghazvin of iran. a section of testa and one mm of endosperm were scraped. 20 gr. of wounded kernels and 20 gr. of unwounded kernels were surface sterilized and then placed in petri...
A research was conducted at Pistachio Research Institute in Rafsanjan, Iran, to evaluate the effects of P. vera L. ‘Badami’, P. vera L. ‘Sarakhs’ and P. mutica F and M. ‘Beneh’ rootstocks on mineral content of leaves and kernels of ‘Owhadi’, ‘Kalleh-ghuchi’ and ‘Ahamd-aghaii’ pistachio scion cultivars. Twenty year old trees of these combinations were used during study over 2003 and 2004. Leaves...
Roasting is the most common way for pistachio nuts processing, and the purpose of that was to increase the products total acceptability. Purpose of this study was to investigate the effect of temperature (90, 120 and 150°C), time (20, 35 and 50 min), and roasting air velocity (0.5, 1.5 and 2.5 m/s) on geometrical attributes of pistachio nuts and kernels including principle dimensions, shape fac...
Pistachio fruit components, including hulls (mesocarps and epicarps), seed coats (testas), and kernels (seeds), all contribute to variable aflatoxin content in pistachios. Fresh pistachio kernels were individually inoculated with Aspergillus flavus and incubated 7 or 10 days. Hulled, shelled kernels were either left intact or wounded prior to inoculation. Wounded kernels, with or without the se...
abstract in order to investigate correlation between the rate (amount) of micro and macro elements and protein percentage in pistachio kernels of six cultivar including: akbari, abbasali, kaleh gouchi, ahmadaghaie, ouhadi and khanjari with aspergillus flavus growth and aflatoxin b1 production, the amount of micro and macro elements were measured using atomic absorption, micro-kjeldhal digestion...
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...
after harvesting, pistachio nuts are generally kept in storage before being exported. during handling, thenuts are exposed to external forces that cause mechanical damage to them. the increase of the mechanicaldamage is a function of storage conditions, especially temperature. this research investigated the effect ofstorage temperature (25, 5, -5, -15°c), on the mechanical properties of pistach...
Population density of Aspergillus section Flavi in pistachio kernels of Iranian cultivars was studied in main pistachio growing areas of Iran during 2015 to 2017. In order to investigate the rate of contamination of pistachio cultivars to Aspergillus section Flavi and aflatoxins, 13 pistachio cultivars, including Akbari, Kaleh-ghouchi, Ovhadi, Ahmad-aghaee, M...
roasting is the common shape of pistachio nuts processing and the purpose of this process is to increase the total acceptability of products. the aim of this study was the effects of hot air roasting temperatures (90, 120 and 150°c), times (20, 35 and 50 min) and air velocities (0.5, 1.5 and 2.5 m/s) on textural attributes (fracture force, hardness, apparent modulus of elasticity and compressio...
