Effects of deficit irrigation, rootstock, and roasting on the contents of fatty acids, phytoprostanes, and phytofurans in pistachio kernels.

Pistachio (Pistacia vera L.) is a drought-tolerant specie grown under the semiarid conditions of the Mediterranean basin. For this reason, it is essential to make an exhaustive quantification of yield and quality benefits of the kernels because the regulated deficit irrigation will allow significant water savings with a minimum impact on yield, while improving kernel […]

Effects of Pistachio Consumption in a Behavioral Weight Loss Intervention on Weight Change, Cardiometabolic Factors, and Dietary Intake.

Epidemiological studies have linked regular nut consumption with lower body mass index and reduced likelihood of weight gain in adulthood. Nuts can displace other foods in the diet, and thus, promote a healthier dietary pattern. The purpose of this study was to examine the effect of pistachio nut consumption in overweight/obese adults. This randomized controlled […]

Oil quality of pistachios (Pistacia vera L.) grown in East Azarbaijan, Iran.

Pistachio nut as a strategic product has a special place from nutritional and economical points of view. Its quality can be affected by variety, growing origin and climate. In the present study, the chemical composition of pistachio nuts harvested from different parts of East Azarbaijan province in Iran (Jolfa, Marand, Soufian, Azarshahr and Islamic Island) […]

The effect of pistachio by‐product extracts treatment in protecting soybean meal and canola meal protein from rumen microbial degradation.

Background: The industrial de-hulling of fresh pistachio generates a large quantity of pistachio by-products (PBP). This study was carried out to investigate the effects of treating soybean meal (SBM) and canola meal (CM) with tannin extracts derived from PBP on the protein fractions according to Cornell Net Carbohydrates and Protein System (CNCPS), rumen degradability and ruminal […]

Identification of novel genes mediating survival of Salmonella on low-moisture foods via transposon sequencing analysis.

Salmonella enterica is the leading foodborne pathogen associated with outbreaks involving low-moisture foods (LMFs). However, the genes involved in Salmonella's long-term survival on LMFs remain poorly characterized. In this study, in-shell pistachios were inoculated with Tn5-based mutant libraries of S. Enteritidis P125109, S. Typhimurium 14028s, and S. Newport C4.2 at approximate 108 CFU/g and stored at 25°C. Transposon sequencing analysis (Tn-seq) […]

Survival and Virulence of Listeria Monocytogenes During Storage on Chocolate Liquor, Corn Flakes, and Dry-Roasted, Shelled Pistachios at 4ºC and 23ºC.

The survival and virulence of Listeria monocytogenes was assessed during storage on three low-moisture foods (LMFs), chocolate liquor, corn flakes and shelled, dry-roasted pistachios (a w 0.18, 0.27, 0.20). The LMFs were inoculated with a 4-strain cocktail of L. monocytogenes at 8 log CFU/g, dried, equilibrated and then stored at 4°C, 25-81% relative humidity (RH) […]

Effects of different roasting methods on formation of acrylamide in pistachio.

Drying and roasting are conventional processes in the nut industry. However, roasting as an important procedure in nuts manufacturing may cause some physicochemical changes in nuts. Acrylamide is one of these chemical compounds that is formed due to the roasting process. Acrylamide is known as a neurotoxicant, carcinogen, and reproductive toxicant. In this study, raw […]

Prevalence of IgE‐mediated sensitization in patients with suspected food allergic reactions in Jordan.

Background: Despite the recognition of food allergies as a significant cause of morbidity and a growing public health burden worldwide, there are no epidemiological studies addressing food sensitization and allergy in Jordan. Objective: To conduct an epidemiological study that retrospectively analyzes sensitization data from 3463 patients with suspected immunoglobulin E (IgE)-mediated food allergic reactions who performed specific […]

Effect of Instant Controlled Pressure Drop (DIC) treatment on the detection of nut allergens by Real Time PCR.

Tree nuts show nutritional properties and human health benefits. However, they contain allergenic proteins, which make them harmful to the sensitised population. The presence of tree nuts on food labelling is mandatory and, consequently, the development of suitable analytical methodologies to detect nuts in processed foods is advisable. Real-Time PCR allowed a specific and accurate […]
