Spectroscopic techniques offer several advantages, including rapid detection, minimal sample loss, and the simultaneous analysis of multiple indicators. They can be applied to assess the sugar content, moisture content, protein content, maturity, mechanical damage, and varietal authenticity of agricultural products. This paper analyzes the mechanisms underlying the spectral responses of agricultural-product quality attributes and reviews methods for spectral acquisition, data preprocessing, feature selection, and model evaluation. It also discusses practical application conditions with reference to detection results obtained for grapes, winter jujubes, and animal-derived meat products. To address the limited applicability of models across varieties, substantial environmental interference, and insufficient stability in online detection, optimization measures are proposed, including expanding sample coverage, integrating multisource information, and improving instrument calibration.
