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. […]
Nutritional quality of almond, canarium, cashew and pistachio and their oil photooxidative stability.
Daily consumption of nuts is recommended as a part of a healthy diet as they contain protein and are rich in beneficial fatty acids and essential nutrients. The nutritional qualities of nuts are affected by their fatty acid composition and other factors such as maturity. Oil oxidative stability is important to determine nut nutritional quality […]
In Vitro Digested Nut Oils Attenuate the Lipopolysaccharide-Induced Inflammatory Response in Macrophages.
Nut consumption is known for its health benefits, in particular in inflammatory diseases. A possible mechanism for these effects could be their beneficial fatty acid composition. Nuts mainly contain mono- and polyunsaturated fatty acids, which have anti-inflammatory properties. However, studies investigating the effects of nut extracts on inflammatory processes on the molecular level are rare. […]
Comprehensive study of phenolic compounds profile and antioxidant activity of eight pistachio cultivars, their residual cakes and virgin oils.
Phenolic compounds of eight pistachio (Pistacia vera L.) cultivars, their residual cakes and virgin oils (screw pressing) were studied using HPLC-DAD-ESI-MS/MS. A total of 25 compounds were identified and quantified for pistachio nuts and residual cakes, being reported for the first time the presence of five flavonols, five six flavanols and one gallotannin. Total phenolics in […]
Salt content dependent dielectric properties of pistachios relevant to radio-frequency pasteurization.
This study was conducted to investigate the effect of salt content during radio-frequency (RF) heating on rate of temperature increase, dielectric properties (DPs), and reduction of pathogens in pistachios. Also, the effect of RF heating on pistachio quality of varying salt content was determined. Pistachios of different salt content (0, 100, and 330 mg sodium/serving) were inoculated with Salmonella […]
