Hello, Guest!

Article about nutritional value of date fruit:
The paper discusses the nutritional and medicinal value of date fruit, which is a significant food source in the Arab Gulf region. It highlights the high carbohydrate content, specifically sugars, and the presence of essential vitamins, minerals, and phytochemicals that contribute to various health benefits. Despite a decline in consumption among younger populations, dates are noted for their potential health-enhancing properties and wide-ranging applications in the development of value-added food products.

Further research is encouraged to fully explore and utilize the beneficial properties of dates and date pits. Key takeaways. Dates provide essential nutrients and demonstrate significant potential health benefits, particularly as a functional food. Average per capita daily consumption in Oman and UAE reaches 164g and 114g, respectively, highlighting cultural significance. Carbohydrates, mainly sugars, account for up to 78% of date content, providing quick energy. Dates contain numerous vitamins and minerals, including calcium, iron, and selenium, with notable antioxidant properties. Further research is needed to explore the medicinal benefits and functional components of dates and date pits. Related papers. IntechOpen eBooks, 2019. The date fruit is economically important agricultural commodity, as well as a staple food in many countries in the Arab world, North Africa, and the Middle East. Recent interest in its nutritional, health, and therapeutic attributes is manifested by the rise in scientific publications. Dates of various cultivars are widely publicized and highly ranked as rich sources of natural antioxidant constituents and antioxidant activity. Such publicity, justified or otherwise, is sometimes accompanied by misconceptions and claims of cultivar-and/or country-wise superiority. This chapter examines these claims using a dataset generated from scientific studies published over the last three decades focusing on the total phenolic (TP) content of three stages of date maturity, with emphasis on the last stage, Tamer. The dataset contains TP values (mg GAE/100 g DM) from 18 countries and 243 cultivars and included 583 entries. It only examines variability of TP values. Statistical analysis indicates a great variability of TP content, both within a particular cultivar and among different cultivars. Claims of cultivar-and country-wise superiority and very high ranking of date antioxidant activity are not substantiated. The chapter also discusses various causes of high variability and calls for a collaboration work to address the issue. The date palm (phoenix dactylifera) is the major fruit tree in the Persian Gulf region including south, southeast and eastern parts of Iran. Date fruit seeds (pits) comprise 6-12% of total weight in Tamr stage (completely ripe date fruit), depending on variety and quality grade. The seeds become available in concentrated quantities when pitted dates are produced in packing plants or in industrial date processing plants based on juice extraction and considered as a waste stream. Finding a way(s) to make value added products and increase the utilization of date seeds other than pulverized date seeds which are being used traditionally on small scale in animal feed, would be beneficial to both date farmers and processors. The presence of large quantities of fiber and substantial amount of tannins, resistant starch, anabolic agents as well as selenium in date seeds are being recently approved by several investigators, suggest that may have health benefit and it is possible to be evaluated as an excellent source of functional foods components. Approximate analysis of date seeds as well as the latest finding on the bioactive constituents with antimicrobial, antioxidant and other health promoting activities will be discussed in detail. International Journal of Food Sciences and Nutrition, 2009. Acta Horticulturae, 2007. Three sun-dried date varieties grown in Oman, namely Fard, Khasab, and Khalas, were examined for their proximate composition and functional constituents, dietary fiber, selenium, antioxidant, carotenoids, phenolics as well as phenolic acids. The study was conducted on dried dates due to their higher consumption compared with fresh dates. All results are expressed as mean value ± standard deviation (n= 3) on a fresh weight basis. Date varieties were found to be low in fat and protein, but rich in dietary fiber and antioxidants. They were found to be a high source of energy (278-301 kcal/100 g), due to the high carbohydrate content. Total dietary fiber content of dates varied from 6.26 to 8.44 g/100 g, of which 84-94% was insoluble fiber. Dates were found to be a good source of antioxidant constituents including selenium (0.356 to 0.528 mg/100 g), total antioxidants (8212-12543 μmol of Trolox equiv/g), carotenoids (0.92-2.91 mg/100 g), and phenolics (217-343 mg of ferulic acid equiv/100 g). Date varieties had different levels and patterns of phenolic acids. Nine phenolic acids (gallic, protocatechuic, p-hydroxybenzoic, vanillic, caffeic, syringic, pcoumaric, ferulic, and o-coumaric acid) were tentatively identified. Ferulic acid was the major phenolic acid for all date varieties. The total content of phenolic acids ranged between 20.24 mg/100g for Khasab and 63.41 mg/100g for Khalas. Of the date varieties studied, Khalas, which is considered to be of premium quality, had higher antioxidant activity, total carotenoids and phenolic acids than other varieties. These results suggest that all date varieties serve as a good source of natural antioxidants and could potentially be considered as a functional food or functional food ingredient. An investigation to harness the potentialities of date fruit to analyze Zahidi (Yellow coloured) and Khuneizi (Red coloured) varieties of date palm fruit was carried out. Date powder of fresh date fruits (doka stage) was developed in form of primary processed product. Value addition of date powder in terms of baked products was found to be organoleptically highly acceptable. The assessment regarding nutraceutical contents of date powder revealed a significant amount of flavonoids (88.26-92.00 CEQ/100g), total phenolic content (468.51- 427.66 mg GAE/100g) and total antioxidant activity by FRAP assay (1227.89- 1071.60 μ mol FRAP/100g). Khuneizi variety had significantly higher (p&lt,.05) flavonoid, phenols and antioxidant activity as compared to Zahidi variety. A strong significant correlation was observed among flavonoids, phenols and antioxidant activity. Thus, date fruits in powdered form have a great potential in baking as well as functional food owing to its nutraceutical contents. Journal of Agricultural and Food Chemistry, 2009. The present pilot study analyzed, for the first time, the in vivo effect of Medjool or Hallawi date consumption by healthy subjects on serum glucose, lipids, and oxidative stress. Total phenolics concentration in the Hallawi versus Medjool dates was greater by 20-31%.
