Physicochemical properties and antioxidant activity of Tunisian date palm (Phoenix dactylifera L.) oil as affected by different extraction methods

Abstract: Materials and methods Chemicals and reagentsAll solvents and standards used in the experiments were purchased from Fisher Scientific Company (Ottawa, Ontario, Canada). SamplesDate palm fruit (Kentichi) were collected at "Tamr stage" (full ripeness) from the oasis of Tozeur (Tozeur, Tunisia). The seeds were isolated, washed and both flesh and seeds were further air dried at 50 °C and then stored at (-20 °C) until analysis and extraction. AbstractThe chemical analysis of flesh and seed of date palm fruit (Kentic… Show more

“…In accordance with method of Aberoumand (2014), moisture was determined by weight loss after heating in blast drying oven (DHG-9640A, Hecheng Instrument Co. Ltd., Shanghai, China) at 105 °C, ash in a muffle furnace (QSH-1700M, Quanshou Electic Furnace Co. Ltd., Shanghai, China) at 550 °C for 5 h. Crude fat was estimated by exhaustive extraction with petroleum ether using Soxhlet apparatus according to Herch et al (2014). Crude protein was calculated from nitrogen, determined by Kjeldahl method, multiplying the value by 6.25 as recommended by Koyuncu et al (2014).…”
