The apple dataset comprised 220 spectral samples and corresponding soluble solid content (SSC) measurements. The spectral data were measured using the Ocean Optics QE Pro high-sensitivity fiber-optic spectrometer, with a wavelength measurement range of 185–1100 nm (the range of 380–1100 nm was selected). SSC measurements were obtained using a PAL-HIKARi apple non-destructive saccharimeter with a measurement accuracy of ±1% Brix.本苹果数据集包含220条光谱样本及对应的可溶性固形物含量（soluble solid content, SSC）检测数据。光谱数据通过海洋光学（Ocean Optics）QE Pro高灵敏度光纤光谱仪采集，其波长测量范围为185–1100 nm，最终选取380–1100 nm区间作为有效波段。可溶性固形物含量检测数据则通过PAL-HIKARi苹果无损糖度计获取，该设备的测量精度为±1%白利度（Brix）。
