摘要： Traditional chemical methods for detecting milk composition suffer from many disadvantages, such as low efficiency and complicated operations. We propose a novel method based on hyperspectral inverse modelling method that combined Savitzky-Golay and first differentiation (SG_FD) to process the spectral data, coupled with an innovative application of improved spatial frog-hopping algorithm (IVRF_CA) to filter the feature wavebands, followed by a voting regressor (VR) to predict the fat and protein content in milk. The results demonstrated that the SG_FD algorithm is a hyperspectral pre-processing method that effectively improves the modelling accuracy, and the IVRF_CA algorithm reduced model complexity while ensuring the accuracy of the model. The test set coefficients of determination (R-2) for the fat and protein partial least squares regression (PLSR) models built using feature wavebands filtered by the IVRF_CA were 0.9608 and 0.8623, respectively, while the corresponding test set R(2 )for the VR model were 0.9834 and 09607, respectively.
