In recent years, the native food industry in Australia has increased in both value and volume due to the discovery of a wide range of phytochemicals (e.g. vitamin C, polyphenols) that have potential health benefits. Thus, plant organs and tissues of these native plants are used in a wide range of applications. In particular, the kernel of a native plum, the Kakadu plum (Terminalia ferdinandiana, Combretaceae) is considered to be rich in lipids and other phytochemical compounds. The aim of this study was to evaluate the use of NIR spectroscopy to analyse and characterise kernel samples and tissues of wild harvest fruit samples. The FT-NIR reflectance spectra of cracked kernels, seeds cover tissues, and dry powder Kakadu plum kernels were acquired. Both principal component analysis and partial least squares discriminat analysis were used to analsye and interpret the spectral data. A correct classification rate of 93%, 86% and 80% was achieved for the identification of kernel provenance using all tissues, seed coats and the whole nuts, respectively. The results of this study reported for the first time the analysis of Kakadu plum kernels and their tissues using NIR spectroscopy.

EXPRESS：使用近红外反射光谱解开榄仁树仁的秘密

近年来，由于发现了多种具有潜在健康益处的植物化学物质（例如维生素 C、多酚），澳大利亚的本土食品工业在价值和数量上都有所增长。因此，这些天然植物的植物器官和组织被用于广泛的应用中。特别是，一种天然李子，卡卡杜李子（Terminalia ferdinandiana，Combretaceae）被认为富含脂质和其他植物化学化合物。本研究的目的是评估使用 NIR 光谱分析和表征野生收获果实样品的籽粒样品和组织。获得了裂果仁、种皮组织和干粉卡卡杜李子仁的FT-NIR反射光谱。主成分分析和偏最小二乘判别分析都用于分析和解释光谱数据。分别使用所有组织、种皮和整个坚果来识别内核来源的正确分类率分别为 93%、86% 和 80%。这项研究的结果首次报告了使用 NIR 光谱分析卡卡杜李子及其组织的结果。
