“…They have a balanced nutritional composition (around 6% fat, 10% protein, and 70e80% dietary fiber). Date seed oil has been studied by other authors, and its composition in vitamins, minerals and fatty acids made it valuable for food formulation (Habib & Kamal, 2013;Nehdi et al, 2010). Besbes et al (2005) studied the effects of heating on date seed oil and they concluded that this oil resisted thermal treatment during a long period of time (30e40 h).…”

a b s t r a c tTwo hydrothermal treatments were assayed on secondary date varieties from the Tunisian coastal oasis in order to obtain valuable solid extracts, rich in dietary fiber and antioxidants. The steam explosion treatment (SET) is based on high temperatures and pressures, with an explosive decompression. The steam treatment (ST), without rapid decompression, has lower pressures and temperatures, but longer treatments than SET. The recovery of the fiber concentrates (FCs) was very similar for the different assayed conditions. Only its granulometry showed differences, increasing the fraction with size lower than 4 mm in more intense treatments. Treatment conditions had higher influence than date variety in the FCs chemical composition. It was approximately 0.1e2% soluble sugar, 0.7e2% uronic acids, 4e8% phenols, 5e11% fat, 5e22% non-cellulosic sugars, 9e14% protein, 12e20% cellulose, and 44e71% lignin, depending on treatment conditions. They had also very high antiradical activity (230e580 mmols Trolox/ Kg FC). The use of ST reactor is highly recommended because it could be easily scaled up to the industry. The FC obtained by hydrothermal treatments from date fruits could be considered as a very interesting ingredient for healthier food, especially for bakery or dairy products due to its pleasant chocolate/coffee flavor.

“…Appropriate conditioning and milling procedures of date pits need to be applied in order to prevent oil rancidity [Hamada et al, 2002;Habib et al, 2013]. Generally date-pits oil can be extracted using organic solvents, such as diethyl ether and hexane.…”

“…It is also recognized as a rich source of compounds including phenolic acids and fl avonoids. Date seeds have also been shown to have excellent nutritional quality due to high amounts of minerals, vitamins, lipids, and protein [5,13]. Additionally, date seeds contain phenolics and total fl avonoids, which have a chelating agent role in contrast to heavy metals accumulation [6].…”

The effects of different doses of date palm (Phoenix dactylifera) seed (DPS) extract on heavy metals (Pb, Cd, As, Hg) concentrations of common carp (Cyprinus carpio) were evaluated. The fi sh (31.6±3.7 g) were assigned to fi ve treatments of three replications each. Five treatments were held using fi ve different DPS extracts at doses of 0% (control), 0.5%, 1%, 2%, and 4%. The results revealed that heavy metals concentrations of fi sh decreased in the 0.5% and 1% treatments (P<0.05). Hg and Cd concentrations in muscle decreased in all treatments (P<0.05). The results of this research clearly show that the addition of DPS extract to a fi sh diet has a signifi cant effect on heavy metals concentrations (P<0.05). DPS extracts were shown to be rich in phenolics and fl avonoids. Therefore, they have also been discussed as protectants against heavy metal stress. It could be concluded that feeding common carp a diet enriched with DPS extract could decrease heavy metals concentrations that can cause cancer.
