“…Acourene et al 125 investigated the potential of date waste as a substrate for the production of citric acid using strains of Saccharomyces cerevisiae ATCC 1102 and Aspergillus niger ATCC 16404. The results showed that 0.1264 kg L −1 citric acid could be obtained under optimal fermentation conditions.…”

Date fruit has served as a staple food in the Arab world for centuries. Worldwide production of date fruit has increased almost threefold over the last 40 years, reaching 7.68 million tons in 2010. Date fruit can provide many essential nutrients and potential health benefits to the consumer. Date fruit goes through four ripening stages named kimri, khalal, rutab and tamer. The main chemical components of date fruit include carbohydrates, dietary fibre, enzymes, protein, fat, minerals, vitamins, phenolic acids and carotenoids. The chemical composition of date fruit varies according to ripening stage, cultivar, growing environment, postharvest conditions, etc. The nutritional and medicinal activities of date fruit are related to its chemical composition. Many studies have shown that date fruit has antioxidant, antimutagenic, anti-inflammatory, gastroprotective, hepatoprotective, nephroprotective, anticancer and immunostimulant activities. Various date fruit-based products such as date syrup, date paste, date juice and their derived products are available. Date by-products can be used as raw materials for the production of value-added products such as organic acids, exopolysaccharides, antibiotics, date-flavoured probiotic-fermented dairy produce, bakery yeasts, etc. In this paper the chemical composition and nutritional and medicinal values of date fruit as well as date fruit-based products are reviewed.

“…The concentrations of citric acid reached to 38.4 and 42.4 g/L, respectively in date medium fortified with methanol and tricalcium phosphate. Acourene et al (2011) investigated the potential of date wastes as substrates for the production of citric acid using Saccharomyces cerevisiae ATCC 1102 and A. niger ATCC 16404. The results showed that the optimal fermentation conditions were fermentation time 144 h, pH and temperature 3.5 and 30°C, respectively using a medium containing (g/L) sugar 150, ammonium nitrate 2.5 and potassium phosphate 2.5.…”

“…Boulal et al (2016) achieved bioethanol production from date palm fruit waste by yeast (Saccharomyces cerevisiae)-mediated fermentation [52,53]. Additionally, other studies have demonstrated that date waste can be used as a substrate to produce citric acid using S. cerevisiae and Aspergillus niger [54]. According to Chauhan et al (2007), date juice is considered as a suitable medium for lactic acid production by Lactobacillus species (KCP01) [55].…”

Many recent studies in the field of cosmetics have focused on organically sourced substances. Products made from organic materials are safe, high quality, cruelty-free, and more effective than those made from synthetic materials. Many organic compounds are known to be physiologically active in humans and have an extended storage capacity and long-lasting environmental effects. Agro-industrial waste has recently increased substantially, and the disposal of date palm waste, often performed in primitive ways such as burning, is harmful to the environment. Fruit processing industries generate over 10% of the total date seed waste daily, which could be converted into useful food products. Date fruit and seed are rich in sugar, vitamins, fiber, minerals, and phenolic compounds with antioxidant and anti-inflammatory properties that significantly promote human and animal health. This waste is rich in bioactive compounds and essential oils used in many kinds of food, medicine, and cosmetics. Most active cosmetic ingredients come from natural sources such as fruit, fish, and dairy, and recent research shows that date extract and seed oil help to reduce melanin, eczema, acne, and dry patches, while increasing skin moisture and elasticity. This review details the bioactive compounds and nutraceutical properties of date fruit and seed, and their use as cosmetic ingredients.
