Walnut fruit: Impact of ethylene assisted hulling on in vitro antioxidant activity, polyphenols, PUFAs, amino acids and sensory attributes.

The effects of three different hulling methods wiz natural heaping/traditional (T1), steeping (T2), and spraying (T3), on moisture, colour, fat, free amino acids, fatty acids, antioxidant activities, flavonoids, tannins, total phenolic content, and organoleptic qualities of walnut kernels were examined in this study. The kernels extracted from walnuts subjected to T3 method recorded significantly (p […]

Quantification of Phytochemicals, Cellular Antioxidant Activities and Antiproliferative Activities of Raw and Roasted American Pistachios (Pistacia vera L.).

The consumption of pistachios has been linked to many potential health benefits. Phytochemicals in pistachios, including phenolics, vitamin E and carotenoids, have been considered to make contributions to the health benefits. The objectives of this study were (1) to explore the phytochemical profiles (total phenolics and total flavonoids, including both free and bound forms), selected […]

Almond and date fruits enhance antioxidant status and have erectogenic effect: Evidence from in vitro and in vivo studies.

This study was designed to investigate the efficacies of almond and date fruits on redox imbalance and enzymes relevant to the pathogenesis of erectile dysfunction. The total polyphenol contents, ferric reducing antioxidant power, and vitamin C content were determined spectrophotometrically. Phenolic and amino acid compositions were quantified using HPLC; meanwhile, the antioxidant activities were determined […]

Emulsion and Microemulsion Systems to Improve Functional Edible Oils Enriched with Walnut and Pistachio Phenolic Extracts

The purpose of this research was to improve the properties of functional edible oils with potential health promoting effects, enriched with phenolic-rich extracts obtained from pistachio and walnut (5.1 and 27.4% phenolic contents respectively), by means of emulsion and micro emulsion systems. Stable water-in-oil (W/O) emulsions were obtained employing polyglycerol polyrhizinoleate (PGPR) as emulsifier (0.5, […]

Effect of cashew nut protein concentrate substitution on the physicochemical properties, antioxidant activity and consumer acceptability of wheat bread

The effect of incorporating different proportions (5, 10, 15 and 20%) of cashew nut protein concentrate (CNPC) on the physicochemical properties, antioxidant activity and consumer acceptability of bread was investigated. Substitution of wheat flour with CNPC increased the water and oil absorption capacity, swelling capacity, peak and final viscosities. Substitution of CNPC in wheat bread […]

Potential Valorization of Edible Nuts By-Products: Exploring the Immune-Modulatory and Antioxidants Effects of Selected Nut Shells Extracts in Relation to Their Metabolic Profiles

The immune system is a potent army that defends our body against various infections and diseases through innate and adaptive immunity. Herbal medicine is one of the essential sources for enhancing immunity because of affordability, availability, minor side effects, and consumers' preferences. Hazelnuts, walnuts, almonds, and peanuts are among the most widespread edible nuts that […]

A Novel Insight into Screening for Antioxidant Peptides from Hazelnut Protein: Based on the Properties of Amino Acid Residues.

This study used the properties of amino acid residues to screen antioxidant peptides from hazelnut protein. It was confirmed that the type and position of amino acid residues, grand average of hydropathy, and molecular weight of a peptide could be comprehensively applied to obtain desirable antioxidants after analyzing the information of synthesized dipeptides and BIOPEP […]

Pistachio Nuts (Pistacia vera L.): Production, Nutrients, Bioactives and Novel Health Effects.

Epidemiological and clinical studies have indicated positive outcomes related to tree nut consumption. Here, we review the production, nutrient, phytochemical composition and emerging research trends on the health benefits of pistachio nuts (Pistacia vera L.). Pistachios are a good source of protein, fiber, monounsaturated fatty acids, minerals and vitamins, as well as carotenoids, phenolic acids, flavonoids […]
