background: nuts are one of the main consumed snacks worldwide and also have an important role among iranian's food habits. natural contamination of nuts with aflatoxin is unavoidable and causes a special challenge for nuts safety and quality. objectives: the purpose of this research was to study the aflatoxin contamination in commercially-available nuts (pistachio, walnut and peanut) in the ma...

background and objectives: edible films and coatings are effective method for decreasing oxidation and increasing the shelf life of pistachios. the present study investigated the effect of an edible gelatin coating containing ascorbic acid (aa: 1% w/v) and propyl gallate (pg: 100 ppm) on the oxidative stability and sensory properties of roasted pistachio nuts. materials and methods: pistachios ...

The use of pesticides on cash crops and exportable food commodities had always been a serious concern. Fruits form one of the important constituents of human diet, in that they give one third of the requirement of calories, vitamins, and minerals. This study has been carried out to determine the level of organochlorine pesticides namely HCH, DDT and Endosulfan in raw fruit nuts. Nuts have prote...

BACKGROUND Nuts are one of the main consumed snacks worldwide and a significant component of Iranian's diet. Natural contamination of nuts with fungus is unavoidable and is a major challenge to nuts safety and quality. OBJECTIVES The purpose of this research was to study fungal contamination in commercially available nuts (pistachios, walnuts and peanuts) in the markets of Tabriz, Iran. MAT...

background: pistachio is one of the main nutrients, not only as a strategic crop but also as a main type of nut, in iranians’ food cycle. the aim of this study was to measure the relative safety of iranian pistachio based on the standard pesticide’s residue limits, which should be monitored and assessed in the cultivation of pistachio in order to confirm its public health. methods: fifty sample...

Lutein and zeaxanthin (L/Z) are the predominant carotenoids which accumulate in the retina of  the eye. The impact of L/Z intake on the risk and progression of age-related macular degeneration (AMD),  a leading cause of blindness in the developed world, has been investigated in cohort studies and clinical  trials. The aims of this review were to critically examine the literature and evaluate th...

pistachio has a special ranking among iranian agricultural products. iran is known as the largest producer and exporter of pistachio in the world. agricultural products are imposed under different thermal treatments during storage and processing. designing all these processes requires thermal parameters of the products such as specific heat capacity. regarding the importance of pistachio proces...

BACKGROUND Proper roasting is crucial to flavor, color, and texture development in the final product. In recent years, several research studies have been carried out to establish the best optimum roasting conditions for some common edible nuts such as; hazelnut, peanut, and pistachio nut. Although roasting is an important process for nuts and oilseeds, there is little or no information on the d...

Recently, Lyn et al. (Analyst, 2007, 132, 1231) compared two ways of estimating the standard uncertainty of sampling pistachio nuts for aflatoxins--a modelling method and an empirical method. Their case study used robust analysis of variance (RANOVA) to derive the uncertainty estimates, highlighting a substantial difference between the two: the estimate of sampling uncertainty derived from the ...
