Recent research has shown the potential of portable and handheld NIR instruments to monitor and measure the composition of fruits and vegetables. Current research has also shown the possibility of using portable instruments as tools to monitor composition along the entire food value chain. The objective of this study was to evaluate two sample presentation methods (dry powder and fruit puree) to measure total soluble solids (TSS) and moisture (M) in wild harvested Kakadu plum (KP) (Terminalia ferdinandiana, Combretaceae). Kakadu plum is an endemic plant of Australia that contains high concentrations of vitamin C, ellagic acid as well as other bioactive compounds. These properties make this plant of high economic and social importance for the Aboriginal communities of Australia. Fruit samples were wild harvested in January 2020 from locations in the Kimberley region (Western Australia, Australia) and analysed using both reference and NIR spectroscopic methods. The SECV and RPD values in cross validation were 0.65% (RPD: 2.2) and 0.22% (RPD: 4.2) to predict M and TSS in the KP dry powder samples. The SECV and RPD values obtained in cross validation for the KP fruit puree samples were 0.56% (RPD: 2.8) and 0.24% (RPD: 3.8) for M and TSS, respectively. The results of this study demonstrated the ability of NIR spectroscopy to measure M and TSS in wild harvest fruit. These findings can be also utilised by the Aboriginal communities to develop a grading/sorting system to rapidly screen and evaluate relevant chemical parameters associated with fruit quality and safety.

最近的研究表明，便携式和手持式NIR仪器具有监测和测量水果和蔬菜成分的潜力。当前的研究还显示了使用便携式仪器作为工具来监测整个食品价值链中成分的可能性。这项研究的目的是评估两种样品呈递方法（干粉和果泥），以测量野生收获的卡卡杜李子（KP）（Terminalia ferdinandiana，孔雀科）。卡卡杜李是澳大利亚的特有植物，其中含有高浓度的维生素C，鞣花酸以及其他生物活性化合物。这些特性使该植物对澳大利亚原住民社区具有重要的经济和社会意义。水果样品于2020年1月从金伯利地区（西澳大利亚州，澳大利亚）野生采收，并使用参考和近红外光谱法进行了分析。交叉验证中的SECV和RPD值分别为0.65％（RPD：2.2）和0.22％（RPD：4.2），以预测KP干粉样品中的M和TSS。在交叉验证中，KP果泥样品的SECV和RPD值分别为M和TSS，分别为0.56％（RPD：2.8）和0.24％（RPD：3.8）。这项研究的结果证明了近红外光谱技术能够测量野果中的M和TSS。这些发现还可以被原住民社区用来开发分级/分选系统，以快速筛选和评估与水果质量和安全性相关的相关化学参数。
