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 […]
Use of a modified QuEChERS method for the determination of mycotoxin residues in edible nuts by nano flow liquid chromatography high resolution mass spectrometry.
A nanoflow liquid chromatography high resolution mass spectrometry method for the quantification of mycotoxins in nuts has been developed. Two strategies based on QuEChERS methodology were evaluated. Thus, EMR-lipid was compared with a conventional mixture of PSA and C18 dispersive solid phase extraction sorbents which have been commonly used in this type of matrices as […]
The Influence of Gamma Radiation Processing on the Allergenicity of Main Pistachio Allergens.
BACKGROUND: Gamma irradiation is a form of processing with an array of applications in medical sciences such as microbial decontamination, viruses inactivation, cervical carcinoma and breast cancer treatment. One of the ways in which gamma irradiation has the potential to be used is in reducing the allergenicity of food allergens. METHODS: In the present study, […]
Growth of Salmonella on Inoculated Inhull Pistachios during Postharvest Handling.
Salmonella has been isolated from dried pistachios in both postharvest and retail surveys. The source of Salmonella in pistachios is unknown, but introduction is possible at points during production, harvest, and postharvest activities. To examine the behavior of Salmonella on pistachios during simulated postharvest conditions, early-, mid-, and late-season inhull pistachios were collected from two commercial processors over five different harvests. Pistachios were inoculated with […]
Extending Storage Potential of De‐hulled Fresh Pistachios in Passive‐Modified Atmosphere.
BACKGROUND: The effects of passive-modified atmosphere packaging (passive-MAP) on the postharvest quality of de-hulled fresh pistachios (Pistacia vera L. cv. Kerman) stored at cold temperature (0 ± 0.5 °C) and 90 ± 1% R.H. was investigated with fruits under ambient air condition as the control treatment. The fruit quality parameters measured included kernel firmness, color […]
The Effects of Nut Consumption on Vascular Function.
Vascular stiffness can be measured using numerous techniques including assessments of central haemodynamics, aortic arterial stiffness, and indices of aortic wave reflection and endothelial dilatation. Impaired vascular function is associated with increased risk of cardiovascular disease (CVD). Epidemiological studies indicate that regular nut consumption reduces CVD risk, with one of the proposed mechanisms being via […]
Pistachio Consumption Prevents and Improves Lipid Dysmetabolism by Reducing the Lipid Metabolizing Gene Expression in Diet-Induced Obese Mice.
Pistachios contain beneficial substances such as unsaturated fatty acids, phytosterols, and polyphenols. In the present study, we investigated if pistachio consumption is able to prevent or to revert hyperglycemia, dyslipidemia, hepatic steatosis, and adipose tissue morphological alterations caused by high fat diet (HFD) in the mouse. Moreover, the impact of pistachio intake on the mRNA […]
