Characterization and Phytotoxicity Assessment of Essential Oils from Plant Byproducts.
The present work describes the chemical characterization and the phytotoxicity assessment of essential oils (EOs) obtained from spent materials or pruning waste of four plant species: Zingiber officinale Roscoe used in the juicing industry, Pistacia vera L. var. Bronte used in the food industry, discarded material of industrial hemp (Cannabis sativa L. var. Futura 75), and pruning waste from Cupressus sempervirens L. The phytochemical profile of […]
Functional and Sensory Properties of Pistachio Nuts as Affected by Cultivar.
BACKGROUND: Modern agriculture allows farmers to choose among different cultivars of the same fruit to fulfill their agronomic needs and consumers' demands; however, there are only few studies describing and comparing key functional and sensory properties of different pistachio cultivars. The main objective of this study was to compare eight pistachio cultivars by analyzing key […]
Pistachio and cashew nut allergy in childhood: Predictive factors towards development of a decision tree.
BACKGROUND: Pistachio and cashew nut, which belong to the same botanical family, are tree nuts that induce serious allergic reactions. OBJECTIVE: We aimed to determine the predictive factors for pistachio and cashew nut reactivity during oral food challenge (OFC). METHODS: A total of 112 pistachio and/or cashew nut sensitized children, aged 58.45 (IQR:40.38-88.32) months, were […]
Cumulative risk assessment of pesticide residues in different Iranian pistachio cultivars: Applying the source specific HQS and adversity specific HIA approaches in Real Life Risk Simulations (RLRS).
Iran is a major supplier of the world pistachio market. In this study, we collected five pistachio cultivars from four main pistachio-producing zones in August and September 2016, and determined the residues of 18 organophosphorus, carbamate, pyrethroid and nicotinoid pesticide in these samples using Gas Chromatography-Mass Spectrometry, as an efficient method for determination of pesticides' residues. Next, single-chemical and chronic […]
Pistachio consumption modulates DNA oxidation and genes related to telomere maintenance: a crossover randomized clinical trial.
BACKGROUND: Telomere attrition may play an important role in the pathogenesis and severity of type 2 diabetes (T2D), increasing the probability of β cell senescence and leading to reduced cell mass and decreased insulin secretion. Nutrition and lifestyle are known factors modulating the aging process and insulin resistance/secretion, determining the risk of T2D. OBJECTIVES: The […]
Effects of a rotational UV‐C irradiation system and packaging on the shelf life of fresh pistachio.
BACKGROUND: In this study, fresh pistachio was exposed to UV-C irradiation (2.1 and 4.5 kJ m-2) in a rotating cylindrical system with seven germicidal UV-C lamps and immediately packed in perforated and non-perforated polyethylene terephthalate (PET). The fruit were evaluated for weight loss, total phenolic content, enzyme activities, color indices (L*, a*, b* and browning […]
A Randomized Controlled Pilot Study to Assess Effects of a Daily Pistachio (Pistacia Vera) Afternoon Snack on Next-Meal Energy Intake, Satiety, and Anthropometry in French Women.
Including nuts in the diet improves appetite control and does not lead to weight gain. However, for pistachios, evidence from randomized intervention studies is limited and there are no data on the effect of pistachios on satiety. The objective of this study was to assess the effect of daily consumption of pistachios as an afternoon […]
Growth of Salmonella and Other Foodborne Pathogens on Inoculated Inshell Pistachios during Simulated Delays between Hulling and Drying.
During harvest, pistachios are hulled, separated in water into floater and sinker streams (in large part on the basis of nut density), and then dried before storage. Higher prevalence and levels of Salmonella were previously observed in floater pistachios, but contributing factors are unclear. To examine the behavior of pathogens on hulled pistachios during simulated drying delays, floater and sinker pistachios collected from commercial […]
Application of Multiplexing Fiber Optic Laser Induced Fluorescence Spectroscopy for Detection of Aflatoxin B1 Contaminated Pistachio Kernels.
To explore the effect of signal acquisition way on screening ability, the multiplexing fiber optic laser induced fluorescence spectroscopy (LIFS) system with one-, two- and three-probe, were employed respectively to detect artificially aflatoxin B1 (AFB1, 5, 10, 20, 30, and 50 ppb) contaminated 300 pistachio kernels in this study. Compared to one- and two-probe modes, highest accuracy […]
Elucidation of Hulling Induced Changes in the Aroma and Aroma-Active Compounds of cv. Uzun (Pistacia vera) pistachio.
BACKGROUND: The purpose of this study was to define the effects of the hulling process on the aroma and aroma-active composition of cv. Uzun pistachio. Four different hulling processes including wet, wet-dry, dry-dry, and brine were applied. In addition, SAFE, SDE, and P&T extraction methods were also tested to obtain the best representative aroma extract. […]
