“…The idea of utilizing a green energy source to reduce cost for bioethanol production from date fruit wastes was pushed forward in the study of Boulal et al, 2016 [41], where they designed a batch fermenter (Figure 7) that utilized a solar water heater for temperature control and to lower the production cost. Similar to the studies of Taouda et al, 2017 [42]; Bouaziz, 2020 [43]; and Ahmad et al, 2021 [31], they utilized Saccharomyces cerevisiae for the date substrate and noticed that between 24 and 48 h, the process of converting glucose to ethanol was active but suddenly decreased after 72 h. The glucose rate decreased from 13.8% to 3% after 72 h, which was determined to be caused by the accumulation of fatty acids, such as octanoic and decanoic acids, that resulted in the cessation of yeast growth. Nevertheless, the study was able to produce ethanol with a high concentration of approximately 90 • , with an acceptable productivity of 250 mL/kg or 3.47 mL/kg•h at a moderate cost.…”

Balancing the needs of current and future generations stimulates investment for sustainable development such as converting waste biomass into biorenewables. Sugar-based ethanol production is a well-investigated and established process, and researchers are now focusing on the transformation of cellulosic biomass to sugar and the application of non-conventional methods for ethanol production. The State of Qatar generates date palm fruit waste of approximately 4505 tons annually, excluding ornamental palms and palms outside the farms that bear nonmarketable date fruits. Date fruit molasses contains fermentable sugars, representing 75% of the total fruit mass, which can offer a good source for bioethanol production through anaerobic fermentation and distillation. On this basis, the valorization of waste date fruits can be an effective zero-waste strategy via biotransformation into bio-renewable materials, hence, contributing to the achievement of sustainable development goals. This paper reviews the potentials and challenges for the utilization of waste date fruits as a bioethanol source and assesses the abundance of waste date fruits as raw material for the conventional bioethanol conversion process. The review also identified conventional and nonconventional processes for bioethanol production and their applicability to Qatar. Finally, this confirmed ample demand for bioethanol ranging from fuel and industrial chemicals to pharmaceutical alcohol.

“…However, the ethanol was produced as by‐product. It was observed that, with time, the ethanol production increased to a concentration of 21.57 g/L, whereas the sugar content decreased (Bouaziz et al, 2020). These results indicated the feasibility of using date seeds for production of ethanol.…”

“…The feasibility of isolating ethanol from date seeds has been assessed in several studies (Bouaziz et al, 2020). Ethanol production typically needs the pretreatment of date seeds to extract sugars, followed by their conversion to ethanol by alcoholic fermentation, which is carried out with the help of different strains of yeast and bacteria (Cheng et al, 2007).…”

The date palm (Phoenix dactylifera L.) industry generates around 1 million tons of date seeds annually. These seeds contain dietary fibers, fatty acids, proteins, and other phytochemical compounds that, if extracted, could be utilized in food, medicine, cosmetics, and energy production. Extracting bioactive compounds from date seeds requires cell degradation to release the intracellular content. Enzymatic hydrolysis (EH) is a biochemical process used to release bioactive molecules stored in date seeds and subsequently produce valuable products. The aim of this review was to highlight the role of EH in the extraction of useful bioactive compounds from the date seeds. Specifically, extraction of the dietary fibers (sugars), proteins, and fatty acids (oils) from the date seeds and their subsequent conversion to bio‐fuel (i.e., ethanol and diesel) are discussed in detail. This review may provide a useful reference for the users of date products. Novelty impact statement The seeds of the date palm (Phoenix dactylifera L.) contain dietary fiber, fatty acids, proteins, and other phytochemicals that, if extracted, could be used in food, medicine, cosmetics, and energy. The use of enzymatic hydrolysis to extract these bioactive compounds from the date seeds and the associated parameters and their optimization are discussed in this study.

“…Date industries have been looking towards developing value-added products, as they are highly profitable and may reduce the risk of date deterioration. 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].…”

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.
