Effect of storage temperatures, packaging materials and storage periods on antioxidant activity and non-enzymatic browning of antioxidant treated walnut kernels.

The effect of antioxidants, temperature, packaging materials and storage periods was investigated in medium shelled walnut kernels (Hamdan) variety. The kernels were mechanically dried (40 °C), standardized and treated with butylated hydroxylanisole and butylated hydroxytoluene in combination at concentrations (0.015%) each. Then packed in laminates under vacuum and high density polyethylene non vacuum packaging materials […]

Fate of aflatoxins during almond oil processing.

Almonds rejected as inedible are often used for production of almond oil. However, low-quality almonds are frequently contaminated with aflatoxins, and little is known regarding transfer of aflatoxins to almond oil during processing. In this study, oil was produced from reject almonds by hexane extraction. Of 19 almond samples that were naturally contaminated with aflatoxins, […]

Physiochemical And Microstructural Properties And Probiotic Survivability Of Symbiotic Almond Yogurt Using Polymerized Whey Protein As A Co-Gelation Agent.

A plain symbiotic almond yogurt-like product was formulated and developed using a plant-based starter YF-L02 (Streptococcus thermophilus, Lactobacillus delbrueckii subsp. bulgaricus supplemented with Lactobacillus acidophilus, Lactobacillus paracasei, and Bifidobacterium animalis) and inulin; 0.6% polymerized whey protein (PWP), 0.3% pectin, and 0.05% xanthan gum were optimized for the formula of the almond yogurt alternative. Two groups […]

Walnut Allergy across Europe: Distribution of Allergen Sensitization Patterns and Prediction of Severity.

Background: Walnut allergy is common across the globe, but data on the involvement of individual walnut components is scarce. Objectives: To identify geographical differences in walnut component sensitization across Europe, explore co-sensitization and cross-reactivity, and assess associations of clinical and serological determinants with severity of walnut allergy. Methods: As part of the EuroPrevall outpatient surveys […]

Efficacy and safety of oral immunotherapy with AR101 in European children with a peanut allergy (ARTEMIS): a multicentre, double-blind, randomised, placebo-controlled phase 3 trial.

Background: Peanut allergy is the leading cause of food-related anaphylaxis. Current management options can negatively affect food allergy-related quality of life. We aimed to investigate the efficacy of an investigational oral biologic drug (AR101). Methods: The AR101 Trial in Europe Measuring Oral Immunotherapy Success in peanut-allergic children (ARTEMIS) trial was a multicentre, double-blind, randomised, placebo-controlled phase 3 […]

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 […]

Walnut intake may increase circulating adiponectin and leptin levels but does not improve glycemic biomarkers: A systematic review and meta-analysis of randomized clinical trials.

Background & objective: Walnut intake is considered a healthy dietary approach worldwide, particularly as a nutritional tool for the management of obesity and cardiometabolic disorders. Among these lines, leptin and adiponectin, as well as glycemic biomarkers, deserve further attention. We aimed to examine the impact of walnut intake on circulation levels of leptin and adiponectin through […]

One-year dietary supplementation with walnuts modifies exosomal miRNA in elderly subjects.

Purpose: Epidemiological studies and clinical trials support the association of nut consumption with a lower risk of prevalent non-communicable diseases, particularly cardiovascular disease. However, the molecular mechanisms underlying nut benefits remain to be fully described. MicroRNAs (miRNAs) are post-transcriptional regulators of gene expression and play a pivotal role in health and disease. Exosomes are extracellular vesicles […]

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 […]
