T he U.S. pistachio industry, which is located almost exclusively in Califor-nia, has experienced phenomenal growth over the past thirty years. The value of U.S. production of pistachios grew from nearly zero in 1976 to $333 million by 2002. The U.S. share of the rapidly growing global pistachio industry has also increased. Outside California, the main pistachio growing region is the Middle Eas...

A simple, fast, reliable, and inexpensive chemical cleanup procedure was developed for quantitation of aflatoxins in major important agricultural commodities by liquid chromatography (LC). Aflatoxins were extracted from a ground sample with methanol-water (80 + 20, v/v), and after a single cleanup step on a minicolumn packed with basic aluminum oxide, they were quantitated by LC equipped with a...

There is a large variability between and among individuals in the physiology of mastication, but it is not known whether this produces a similar variability in the particle sizes of food boluses at the end of the chewing process. Food boluses obtained just before swallowing were analyzed in ten subjects (aged 36.7 +/- 9.5 yrs) with normal dentition. Food samples of 3 nuts (peanut, almond, pista...

pistachio nuts are the major non-oil export agricultural commodity in iran. the existence of empty shells among the shells with kernels reduces the quality of the nuts and, consequently, their market value. in pistachio processing plants, empty shells are generally separated from shells with kernels by the flotation method. but this method is not precise and may encourage the growth of fungi in...

Aflatoxin B1 (AFB1) is a secondary metabolite produced by some Aspergillus species, which haveharmful impacts on human health such as carcinogenicity, teratogenicity, acute and chronic toxicity.In this study, the occurrence of AFB1 in pistachio nuts during various preparing processes wasinvestigated in two pistachio farms from Qazvin province, Iran, from September to November 2012.High Performa...

pistachio nut is one of the most important export crops in iran. for prevention of rancidity and to ensure good quality, pistachio must be harvested in a short time and be prepared for drying in 24h.the ohadi variety of iranian raw dry pistachio nuts was selected for the experiments. instrumental hardness and sensory characteristics of pistachio nuts such as: flavor , texture and total acceptan...

Among the most important problems of pistachio are physiological disorders such as fruit abscission and production of blank nuts. Environmental stresses and inadequate nutrition during flowering time have increased these problems in recent years. In order to evaluate the effects of foliar treatments with polyamines and other compounds (amino acids and ascorbic acid) on quantitative and qualitat...

It is proven that nuts contain essential macro- and micronutrients, e.g. fatty acids, vitamins and dietary fibre (DF). Fermentation of DF by the gut microflora results in the formation of SCFA which are recognised for their chemopreventive potential, especially by influencing cell growth. However, little is known about cellular response to complex fermentation samples of nuts. Therefore, we pre...

Background: The pistachio is a nut produced by about 20 species of shrub. Present-day studies show the health benefits of pistachio in preventing or treating diseases such as diabetes, cardiovascular diseases (CVDs), cancer, multiple sclerosis (MS), and erectile dysfunction. Materials and Methods: MEDLINE / PubMed, and Google Scholar databases were searched using the keywords of Pistacia ver...
