(Kakadu plum) is a native Australian fruit. Industrial processing of fruits into puree generates seeds as a by-product, which are generally discarded. The aim of our present study was to process the seed to separate the kernel and determine its nutritional composition. The proximate, mineral and fatty acid compositions were analysed in this study. Kernels are composed of 35% fat, while proteins account for 32% dry weight (DW). The energy content and fiber were 2065 KJ/100 g and 21.2% DW, respectively. Furthermore, the study showed that kernels were a very rich source of minerals and trace elements, such as potassium (6693 mg/kg), calcium (5385 mg/kg), iron (61 mg/kg) and zinc (60 mg/kg) DW, and had low levels of heavy metals. The fatty acid composition of the kernels consisted of omega-6 fatty acid, linoleic acid (50.2%), monounsaturated oleic acid (29.3%) and two saturated fatty acids namely palmitic acid (12.0%) and stearic acid (7.2%). The results indicate that kernels have the potential to be utilized as a novel protein source for dietary purposes and non-conventional supply of linoleic, palmitic and oleic acids.
卡卡杜李是一种澳大利亚本土水果。将水果加工成果泥的工业过程会产生种子这一副产品，这些种子通常会被丢弃。我们当前研究的目的是对种子进行加工以分离出果仁并确定其营养成分。本研究分析了其近似成分、矿物质和脂肪酸组成。果仁含有35%的脂肪，而蛋白质占干重（DW）的32%。能量含量和纤维含量分别为2065千焦/100克和21.2% DW。此外，研究表明，果仁是矿物质和微量元素的丰富来源，如钾（6693毫克/千克）、钙（5385毫克/千克）、铁（61毫克/千克）和锌（60毫克/千克）DW，且重金属含量较低。果仁的脂肪酸组成包括ω-6脂肪酸亚油酸（50.2%）、单不饱和油酸（29.3%）以及两种饱和脂肪酸，即棕榈酸（12.0%）和硬脂酸（7.2%）。结果表明，果仁有潜力被用作新型蛋白质来源以满足饮食需求，并非常规供应亚油酸、棕榈酸和油酸。
