This investigation aimed to evaluate the chemical composition and physicochemical properties of seed oils from 6 date palm (Phoenix. dactylifera L.) cultivars (Barhi, Khalas, Manifi, Rezeiz, Sulaj, and Sukkari) growing in Saudi Arabia and to compare them with conventional palm olein. The mean oil content of the seeds was about 7%. Oleic acid (48.67%) was the main fatty acid, followed by lauric acid (17.26%), stearic acid (10.74%), palmitic acid (9.88%), and linolenic acid (8.13%). The mean value for free fatty acids content was 0.5%. The P. dactylifera seed oil also exhibited a mean tocol content of 70.75 mg/100 g. α-Tocotrienol was the most abundant isomer (30.19%), followed by γ-tocopherol (23.61%), γ-tocotrienol (19.07%), and α-tocopherol (17.52%). The oils showed high thermal and oxidative stabilities. The findings indicate that date seed oil has the potential to be used in the food industry as an abundant alternative to palm olein. PRACTICAL APPLICATION This study showed that date seed had great nutritional value due to which it can be used for food applications especially as frying or cooking oil. In addition, date oil has also potential to be used in cosmetic and pharmaceutical practices as well. The extraction of oil from Phoenix dactylifera seed on large scale can create positive socioeconomic benefits especially for rural communities and could also assist to resolve the environmental issues generated by excess date production in large scale date-producing countries such as Saudi Arabia.

六种沙特阿拉伯品种枣椰树 (Phoenix dactylifera L.) 种子油的化学成分

本研究旨在评估生长在沙特阿拉伯的 6 种海枣 (Phoenix. dactylifera L.) 品种（Barhi、Khalas、Manifi、Rezeiz、Sulaj 和 Sukkari）的种子油的化学成分和物理化学特性，并将它们与常规棕榈油精。种子的平均含油量约为 7%。油酸（48.67%）是主要脂肪酸，其次是月桂酸（17.26%）、硬脂酸（10.74%）、棕榈酸（9.88%）和亚​​麻酸（8.13%）。游离脂肪酸含量的平均值为 0.5%。P. dactylifera 种子油的平均母育酚含量也为 70.75 mg/100 g。α-生育三烯酚是最丰富的异构体（30.19%），其次是γ-生育酚（23.61%）、γ-生育三烯酚（19.07%）和α-生育酚（17.52%）。这些油表现出高的热稳定性和氧化稳定性。研究结果表明，枣籽油有潜力在食品工业中用作棕榈油精的丰富替代品。实际应用 这项研究表明，枣子具有很高的营养价值，因此可用于食品，尤其是煎炸或食用油。此外，枣油也有可能用于化妆品和制药实践。大规模从凤仙花种子中提取油可以创造积极的社会经济效益，特别是对农村社区而言，还可以帮助解决沙特阿拉伯等大规模枣生产国过度生产枣产生的环境问题。实际应用 这项研究表明，枣子具有很高的营养价值，因此可用于食品，尤其是煎炸或食用油。此外，枣油也有可能用于化妆品和制药实践。大规模从凤仙花种子中提取油可以创造积极的社会经济效益，特别是对农村社区而言，还可以帮助解决沙特阿拉伯等大规模枣生产国过度生产枣产生的环境问题。实际应用 这项研究表明，枣子具有很高的营养价值，因此可用于食品，尤其是煎炸或食用油。此外，枣油也有可能用于化妆品和制药实践。大规模从凤仙花种子中提取油可以创造积极的社会经济效益，特别是对农村社区而言，还可以帮助解决沙特阿拉伯等大规模枣生产国过度生产枣产生的环境问题。
