The world production of date fruit increases 2.9 times over 40 years, whereas the world production reached to 7.68 million tons in 2010. Date fruit can provide many essential nutrients and potential health benefits to the host. Date fruit goes through four ripening stages named by kimri, khalal, rutab and tamer. The main chemical compositions of date fruit include carbohydrates, dietary fiber, enzymes, protein, fat, minerals, vitamins, phenolic acids and carotenoids etc. Chemical compositions of date fruit change with ripening stages, the cultivar, growing environment and post-harvest conditions etc. Nutritional and medicinal activities of date fruit are related to its chemical compositions. Many studies have shown that date fruit has antioxidant, anti-mutagenic, anti-inflammatory, gastroprotective, hepato-protective, nephro-protective, anticancer, immune-stimulant activities etc. Many date fruit-based products such as date syrup, date paste, date juice and their derived products, have been available. Date by-products can be used as raw materials for the production of value-added products such as organic acids, exopolysaccharide, antibiotics, date flavored probiotic fermented dairy and bakery yeast etc. In this paper, chemical compositions, nutritional and medicinal values of date fruit and date fruit-based products were reviewed. Key takeaways. Date fruit production reached 7.68 million tons in 2010, with a projected 2.9-fold increase over 40 years. Chemical compositions of date fruit vary by ripening stage: kimri, khalal, rutab, and tamer. Date fruit exhibits numerous health benefits, including antioxidant, anti-inflammatory, and hepato-protective activities. Dietary fiber in date fruit aids in gastrointestinal health and may play a role in diabetes prevention. Date fruit-derived products include syrups, pastes, and potential substrates for fermentation-derived value-added products. Related papers. Journal of the Saudi Society of Agricultural Sciences, 2017. The aim of this study was to determine the functional composition and antioxidant activities of eight major date fruit varieties grown in Morocco. The analysis shows that date fruit contains a high amount of sugar (66.03-83.05% DW) but a low content of fat (0.218-0.363% DW) and protein (2.2-3.45% DW). Among the eight studied minerals potassium, calcium and magnesium were the predominant. Moreover, the niacin is the major B vitamin of all analyzed varieties. The total phenolic content was found between 331.86 and 537.07 mg GAE/100 g DW, the flavonoid between 68.88 and 208.53 mg of RE/100 g DW and condensed tannins between 57.56 and 92.141 mg CE/100 g DW, the antioxidant activity ranged between 383.90 and 846.94 lmol TE/100 g DW for ABTS, 6.255 and 2.046 g of date/l for DPPH IC50 and 406.614 and 860.89 lmol TE/100 g DW for FRAP assays. The results suggest that date fruit, which is good source of vital nutrients and antioxidant, is an extensive and varied field. Food Chemistry, 2007. Three native sun-dried date varieties from Oman (namely Mabseeli, Um-sellah, and Shahal), as well as their syrups and by-products (press cake and seed) were examined for their proximate composition, dietary fibre, total phenolics, and total antioxidant activity. Carbohydrate was the predominant component in all date varieties, syrups, and their by-products, followed by moisture, along with small amounts of protein, fat, and ash. Press cakes had the highest protein content, ranging in concentration from 3.62 g/100 g in Shahal to 5.23 g/100 g in Mabseeli, whereas fat was the highest in seeds and ranged from 5.02 g/100 g in Mabseeli to 5.90 g/100 g in Um-sellah. Seeds and press cakes were found to be good sources of dietary fibre, varied between 77.75 and 80.15 g/100 g fresh weight and between 25.39 and 33.81 g/100 g fresh weight, respectively. Among dates, syrups, and their by-products, seeds had the highest contents of total phenolics (3102–4430 mg of gallic acid equivalents/100 g fresh weight) and antioxidant activity (580–929 μmol of Trolox equivalents/g fresh weight). The results obtained suggest that date by-products (particularly seeds) serve as a good source of natural antioxidants and could potentially be considered as a functional food or functional food ingredient. Journal of New Sciences, 2016. The present study deals with the biotechnological valorization of dates having low market value, the production of the juice of eight cultivars of Tunisian date palm (Phoenix dactylifera L.) fruits grown in Gabes region (Oasis of Gabes, Tunisia) have analyzed their juice extracts for their nutritional quality, TPC, TFC, TCT and antioxidant activities using ABTS, DPPH, and FRAP assays. The analysis has shown that fruits of date cultivars contain a high amount of sugar (37.75-67.34 % FW) and the total sugars obtained by HPLC method showed that only DegletNour variety contains sucrose (non reducing sugar). But, a low content of fat (0.142-0.24% FW) and protein (1.19-2.89% FW) was found. For the minerals content, the fruit of dates are considered as very important sources of potassium and several minerals, followed in decreasing order by calcium, magnesium, sodium, iron, zinc and manganese. The obtained results have shown that all samples had the highest TPC, TFC, CTC, and the values of antioxidant of Trolox equivalent were higher in ABTS assay than those observed by DPPH and FRAP methods. A significant correlation was found between TPC, TFC, CTC and antioxidant activities. This syrup, produced by simple technological means, was rich in reducing sugars. These results suggest that this syrup, containing high nutriments value and natural antioxidants, might be more widely used by the food industry as a source of bioactive human health promoter phytochemicals. Brazilian Journal of Biology, 2022. Date fruit is known to be the staple food in the Arab countries. It provides a lot of potential health benefits and can be the essential source of nutrients. The majority of Moroccan varieties are not characterized for their chemical, biochemical and quality properties. The aim of this work was to assess the chemical composition of 17 varieties of Moroccan date fruits (Phoenix dactylifera L.) and to determine their nutritive components. The analysis showed that the dates are rich in sugars (51.80-87.98%), they contain low concentration of proteins (1.09-2.80%) and lipids (0.16-0.39%).
