fcis-31661	Li, Zhipeng	Research on Apple Internal Quality Classification Based on Near-Infrared Spectroscopy	2025	4	.pdf	application/pdf	2534	113	47	The near-infrared spectral data of apple samples were collected using a near-infrared spectrometer (model ATP8600, wavelength range 997-1708nm, Optiancheng Company), as shown in Figure 1. The sugar content values of apple samples were collected using a handheld refractometer (ATAGO PAL- BX|ACID8, with a detection range of soluble sugar from 0.0 to 90%, an accuracy of ±0.2%, and a suitable temperature range of 9.0 to 99.9℃), as shown in Figure 2.	cache/fcis-31661.pdf	txt/fcis-31661.txt
