Quantification of the aflatoxin biocontrol strain Aspergillus flavus AF36 in soil, and nuts and leaves of pistachio by real-time PCR.
The species Aspergillus flavus and A. parasiticus are commonly found in the soils of nut-growing areas in California. Several isolates can produce aflatoxins that occasionally contaminate nut kernels conditioning their sale. The strain AF36 of A. flavus, which does not produce aflatoxins, is registered as a biocontrol agent for use in almond, pistachio, and fig […]
Rapid detection of green pea adulteration in pistachio nuts using raman spectroscopy and chemometrics.
Background: Ground pistachio nut is prone to be adulterated because of its high economic value and wide usage area. Green pea is known as the main adulterant in the frauds of pistachio nuts. Present study developed a new, rapid, reliable and low-cost methodology by using a portable Raman spectrometer in combination with chemometrics for detection of […]
Mathematical modeling and experimental study of VOC adsorption by Pistachio shell–based activated carbon.
The adsorption of benzene vapor, as a volatile organic component, from inert gas (N2) by activated carbon was studied experimentally in the isothermal fixed bed reactor at various operating conditions. The activated carbon used in this study had pistachio shell base with high surface area. To improve the adsorption capacity of VOC vapor, the activated […]
Biocontrol potential of native yeast strains against Aspergillus flavus and aflatoxin production in pistachio.
Aspergillus flavus is the main aflatoxin producer in food and feed and has wide ecological niches. Contamination of food products such as pistachio nuts and aflatoxin secretion directly affects food safety and international food product trades. Abilities of 13 yeast strains isolated from 200 soil and pistachio nut samples collected in Iranian orchards to reduce […]
Phage Displayed Domain Antibodies (dAb) for Detection of Allergenic Pistachio Proteins in Foods.
Pistachio nuts (Pistacia vera) have been consumed by past and present-day civilizations because of their organoleptic characteristics and potential health benefits. However, they can also produce moderate to severe IgE-mediated reactions in allergic individuals. In this work, we report the isolation of the first recombinant antibodies against pistachio nut, produced without animal immunization, to be […]
Pistachios and cardiometabolic risk factors: a systematic review and meta-analysis of randomized controlled clinical trials.
Background: Previous experimental studies have reported that pistachios can elicit positive effects on lipid profile, blood pressure, and inflammation; however, a meta-analysis of the available evidence has yet to be performed. Objective: the aim of this study was to conduct systematic review and meta-analysis of the effect of pistachio enriched diets on cardiometabolic risk factors, such as […]
The effectiveness of pistachio on glycemic control and insulin sensitivity in patients with type 2 diabetes, prediabetes and metabolic syndrome: A systematic review and meta-analysis.
Background and aims: Pistachio nuts have been considered to improve dysglycemia. However, there are controversial results. This systematic review and meta-analysis carried out to evaluate the effects of pistachio nuts on glycemic control and insulin sensitivity in patients with type 2 diabetes mellitus (T2DM), prediabetes, and metabolic syndrome. Methods: Medline/PubMed, ProQuest, Web of Knowledge, Scopus, Cochrane library, […]
Potential probiotic and food protection role of wild yeasts isolated from pistachio fruits (Pistacia vera).
Background: The biotechnological potential of yeasts from nuts such as pistachio, not only for health applications but also for industry use, is scarcely studied. Interest in the probiotic capability of yeasts has increased in the past years as well as their utilisation as food or feed preservatives. Their capabilities as biocontrol against problematic (spoilage or toxigenic) […]
Spray Drift Mitigation Using Opposing Synchronized Air‐Blast Sprayers.
Background: Pesticide drift is a serious environmental and safety concern that affects all of U.S. agriculture. A number of mitigation techniques to reduce pesticide drift have been recommended by industry, academic and government agencies. These techniques are very costly or reduce the efficacy of the pest control product and have not been implemented by U.S. agriculture. […]
Modeling the Effects of Product Temperature, Product Moisture, and Process Humidity on Thermal Inactivation of Salmonella in Pistachios during Hot-Air Heating.
Prior efforts to model bacterial thermal inactivation in/on low-moisture foods generally have been based on isothermal and iso-moisture experiments and rarely included dynamic product and process variables. Therefore, the objective of this study was to test appropriate secondary models to quantify the effect of product temperature, product moisture, and process humidity on thermal inactivation of […]
