| Summary: | Phoenix dactylifera L (Date palm) is one of the oldest known fruit crops in the world, and
the consumption of date fruits is no longer restricted to the Middle Eastern countries. Date
palm kernels are waste products of date fruit industry which are normally being discarded.
Based on their dietary fiber content; date palm kernels (DPK) have been proposed to be used
as fiber-based food supplement, caffeine free coffee alternative and animal feed ingredient.
Hence, utilization of such waste is highly desirable for the date industry. To accommodate these
benefits, and subsequent to some uses associated with DPK, this study sought to investigate the
biochemical and nutritional values of the Barhi date palm kernels (BDPK) grown in Iraq. The
results show that BDPK is an excellent source of dietary fiber (66.24 g/100g). Glutamic acid
was found to be the predominant amino acid, (0.674 g/100g), followed by Arginine and aspartic
acid (0.437 g/100g and 0.320 g/100g, respectively). Potassium was the most occurring mineral
in BDPK (2.39 g/kg), and the main sugars were sucrose and fructose (0.548 g/100g and 0.249
g/100g, respectively). Gas-liquid chromatography revealed that the main unsaturated fatty acid
(USFA) was oleic acid (40.927 mg/100g), while the main saturated fatty acid (SFA) were lauric
acid (20.270 mg/100g) and myristic acid (12.288 mg/100g). Furthermore, the BDPK depicted
considerable concentrations of vitamins, in which vitamin B5 (40.4 mg/100g) showed the
highest value. The results obtained indicate a strong potential for BDPK to be used in human
nutrition, cosmetics, and pharmaceutical applications and may provide an important economic
advantage through increasing the utilization of BDKP while also additive value will be added
to the residue. |
