Extraction and Characterization of Oil from Date Palm (Phoenix dactylifera) Seed

Abstract

This work focuses on the extraction of oil from date palm seed. Using n-hexane in Soxlet extraction apparatus, standard procedures were followed to determine the oil feed stock yield. Proximate compositions and physicochemical characteristics were carried out. Also, Fourier Transform Infrared Spectroscopy (FTIR) and Gas Chromatography Mass Spectrometry (GC-MS) were used to determine the functional groups and the fatty acid composition of the oil respectively. The result shows that the appearance of date palm seed oil is reddish brown in colour. Result from the FTIR analysis also shows that 17 peaks were noticed from date palm seed oil, indicating the presence of various functional groups such as OH, C-H, C=C, C=O, C The dominating types and number of functional groups are found on the single bond stretch and on the fingerprint region skeletal vibration. Similarly, the GC-MS result also reveals that there are 5 dominating fatty acid compounds present in date palm seed oil in relation to their abundant relative weight composition. In date seed oil, oleic acid which comprise of omega-9 fatty acid is found to be the only monounsaturated fatty acid with the highest weight composition of 49.4%. The inference that can be drawn from the results in this work in relation to application suggest that, date palm seed oil will be suitable for soap production and cleansing agents. Also, omega-9 fatty acid has some health benefits that can strengthen the brain as well as the heart. Furthermore, research on the life shelf and storage of this oil should be looked into, as it relates to the peroxidation of oil.

Poly(ethyl acrylate-co-methyl Methacrylate-co-trimethylammoniethyl methacrylate chloride) (Eudragit RS100) Nanocapsules as Nanovector Carriers for Phoenix dactylifera L. Seeds Oil: a Versatile Antidiabetic Agent

“…The peak at 721 cm –1 corresponds to the aromatic compounds. These results were similar to those obtained in the literature. − The FTIR spectra of Eudragit RS100 showed characteristic peaks at 2950 cm –1 due to CH aliphatic stretching, at 1722 cm –1 due to CO ester stretching, and a peak at 1143 cm –1 that corresponds to the CO ester group. This was in accordance with what was reported. , Matching up to the FTIR spectrum of Eudragit with the oil-loaded nanoparticles revealed a reduction in the intensity of the peak at 1725 cm –1 as well as coming out of three jointed peaks in 2924, 2853, and 1466 cm –1 that characterize DS oil.…”

“…The peaks at 1743 and 1160 cm -1 correspond to stretching vibration of the C=O and C-O groups of the ester, respectively. These findings were in agreement with those reported in [48][49][50][51][52].…”

“…Besides, date seeds are used as animal feed or caffeine-free coffee replacements in some areas. The Ajwa date seed oil includes sterol, phytochemistry, oleic, palmitic and fatty acids and their derivatives; these have antibacterial, antioxidant, anticancer and antilipidemic effects [72,73]. The present work reported that Ajwa date seed oil (AWSO) contains hexadecanamide, 5-hydroxymethylfurfura, 9-octadecenamide, (Z)-, oleic acid, cis-11-eicosenamide, dodecanoic acid and palmitic acid.…”
