Potential health benefits and quality of dried fruits: goji fruits, cranberries and raisins.
Dried fruits are important snacks and additives to other foods due to their taste and nutritional advantages. Therefore there is an important goal to control the quality of the food on the market for consumer's safety. Antioxidant activity of goji fruits (Lycium barbarum), cranberries (Vaccinium macrocarpon and oxycoccus) and raisins (Vitis vinifera) were studied using […]
Physico-chemical characteristics and fungal profile of four Saudi fresh date (Phoenix dactylifera L.) cultivars.
Physico-chemical and microbial analyses of four commercial fresh date cultivars (Sukari, Barhi, Khalas and Rothana) grown in Saudi Arabia were evaluated. Colorimetric assay indicated that Sukari had the highest total sugar content of 13.21g/100gFW while the lowest was in Rothana with 7.96g/100gFW. Total phenolic content (TPC) ranged from 76.74 to 122.20mgGAE/100gFW in Barhi and Rothana […]
Acetone Extract of Almond Hulls Provides Protection against Oxidative Damage and Membrane Protein Degradation.
Several studies have revealed that among foods, the consumption of edible nuts has beneficial effects on health which are attributed to their high content of potent antioxidants. Among nuts, the whole seed of the almond (Prunus dulcis) has been demonstrated to possess potent free radical scavenging activity, which is related to the presence of phenolic […]
Evaluation of the Anti-Inflammatory Activity of Raisins (Vitis vinifera L.) in Human Gastric Epithelial Cells: A Comparative Study.
Raisins (Vitis vinifera L.) are dried grapes largely consumed as important source of nutrients and polyphenols. Several studies report health benefits of raisins, including anti-inflammatory and antioxidant properties, whereas the anti-inflammatory activity at gastric level of the hydro-alcoholic extracts, which are mostly used for food supplements preparation, was not reported until now. The aim of this study was to […]
Pistachios for Health: What Do We Know About This Multifaceted Nut.
Human beings have known about pistachio nuts since 6000 bc. Since then, pistachios have been systematically incorporated into the diet of various cultures. They are nutrient-dense nuts with a healthy nutritional profile that contains fiber, unsaturated fatty acids and antioxidant compounds.
Nuts and their co-products: The impact of processing (roasting) on phenolics, bioavailability, and health benefits – A comprehensive review.
Nuts serve as important healthful snacks worldwide. They are highly desirable due to the presence of numerous essential macro- and micronutrients and health-promoting phenolic compounds (polyphenols). Nuts are usually consumed either as raw (natural) or as roasted. In addition, nuts and their co-products have been demonstrated to be rich sources of phenolic compounds that possess […]
Antioxidant and hepatoprotective properties of dried fig against oxidative stress and hepatotoxicity in rats.
The aim of this study was to investigate the hepatoprotective effect and antioxidant role of dried fig (DF) (Ficus carica L.) against ethanol-induced oxidative stress. Experiment was designed as normal Control, 20% ethanol, 10% DF and 10% DF+20% ethanol groups. The hepatoprotective and antioxidant role of the dried DF supplementation feed against ethanol induced oxidatif […]
Antibacterial Properties and Effects of Fruit Chilling and Extract Storage on Antioxidant Activity, Total Phenolic and Anthocyanin Content of Four Date Palm (Phoenix dactylifera) Cultivars.
Phoenix dactylifera or date palm fruits are reported to contain natural compounds that exhibit antioxidant and antibacterial properties. This research aimed to study the effect of fruit chilling at 4 °C for 8 weeks, extract storage at -20 °C for 5 weeks, and extraction solvents (methanol or acetone) on total phenolic content (TPC), antioxidant activity […]
In Vivo Evaluation of Anti Diabetic, Hypolipidemic, Antioxidative Activities of Saudi Date Seed Extract on Streptozotocin Induced Diabetic Rats.
INTRODUCTION: Phoenix dactylifera (date palm) is major fruit of gulf region. In folk medicine; dates have been traditionally use. The date seed is used as hypoglycaemic, expectorant, tonic, aphrodisiac, antidiarrheic and mouth hygiene. AIM: This study intended to evaluate the anti-diabetic, hypolipidaemic and antioxidative activities of date seed extract in diabetes-induced rats. MATERIALS AND METHODS: […]
Optimization of Aqueous Extraction Conditions for Recovery of Phenolic Content and Antioxidant Properties from Macadamia (Macadamia tetraphylla) Skin Waste.
The macadamia is native to Australia and is now grown commercially around the world. Macadamia skin, known as waste, has been generated abundantly, but this ample source has had limited uses as a byproduct. The aim of this study was to develop optimal aqueous extraction conditions for the recovery of phenolic compounds and antioxidant properties […]
