Date seed oil is a good source of natural antioxidants due to the presence of phenols, tocopherols, and sterols. The present research is the first study on the extraction of date seed oil by combining the ultrasound-assisted aqueous enzymatic extraction method and the cooking pretreatment. In this study, the effects of two independent variables namely the sample to solvent ratio (at six levels of 1: 2, 1: 3, 1: 4, 1: 6, 1: 8 and 1:10) and the cooking time (at four levels of 0, 20, 40 and 60) were investigated on dependent variables namely the extraction yield, total phenolic compound, peroxide value, and acid value of date seed oil. The results indicated that optimum conditions for extraction of date seed oil were sample to solvent ratio of 1: 2 and the cooking time of 40 min. Furthermore, the Scanning Electron Microscopy images of date seed powder after selective treatments indicated the destruction and fragmentation of residual pulp structures by increasing the cooking time. In general, results of the present study indicated that it was important to select the appropriate sample to solvent ratio and implement the pretreatment of cooking to extract oil with high yield and quality. Combination of the ultrasound-assisted aqueous enzymatic extraction method and the cooking pretreatment can be proposed as a new extraction method in the oil industry. This new extraction method can improve the oil extraction efficiency and the quality of extracted oil.

超声辅助水酶提取与蒸煮预处理相结合,回收枣籽油

由于存在酚,生育酚和固醇,枣籽油是天然抗氧化剂的良好来源。本研究是超声辅助水酶提取法与蒸煮预处理相结合提取枣籽油的首次研究。在这项研究中,两个独立变量的影响即样品与溶剂的比例(六个级别的1:2:1:3、1:4、1:6、1:8和1:10)和烹饪时间(在0、20、40和60这四个水平下,对枣籽油的提取率,总酚类化合物,过氧化物值和酸值等因变量进行了研究。结果表明,提取枣籽油的最佳条件是样品与溶剂的比例为1:2,蒸煮时间为40分钟。此外,选择性处理后的枣种子粉末的扫描电子显微镜图像显示,通过增加烹饪时间,残留果肉结构被破坏和破碎。通常,本研究的结果表明,选择合适的样品与溶剂的比例并实施蒸煮以提取高收率和高质量的油非常重要。超声辅助水酶提取法与蒸煮预处理相结合可以作为石油工业中一种新的提取方法。这种新的提取方法可以提高油的提取效率和提取油的质量。本研究的结果表明,选择合适的样品与溶剂的比例并实施蒸煮的预处理以高收率和高质量地提取油非常重要。超声辅助水酶提取法与蒸煮预处理相结合可以作为石油工业中一种新的提取方法。这种新的提取方法可以提高油的提取效率和提取油的质量。本研究的结果表明,选择合适的样品与溶剂的比例并实施蒸煮的预处理以高收率和高质量地提取油非常重要。超声辅助水酶提取方法与蒸煮预处理相结合可以作为石油工业中一种新的提取方法。这种新的提取方法可以提高油的提取效率和提取油的质量。
