OBJECTIVE To establish a rapid nondestructive detection method for the sporoderm-broken rate of Ganoderma lucidum spore powder by hyperspectral technology combined with chemometrics. METHODS Hyperspectral images of Ganoderma lucidum spore powder samples with different sporoderm-broken rates were collected, and spectral data in the visible-shortwave near-infrared band(397−1 004 nm) range of each sample were calculated after selecting the region of interest. Compared 6 spectral preprocessing methods[standard normal variable transformation, multivariate scattering correction, Savitsky-Golay(SG) smoothing, wavelet transform, SG smoothing+standard normal variable transformation, and SG smoothing+multivariate scattering correction], 5 characteristic band extraction methods(competitive adaptive reweighting, successive projections algorithm, uninformative variables elimination, least angle regression, and genetic algorithm), and 5 algorithms(partial least squares regression, support vector regression, extreme learning machine, multilayer perceptron, and LightGBM) for constructing quantitative correction models to predicts performance. RESULTS The optimal combination was SG smoothing+competitive adaptive reweighted feature band selection+partial least squares. The quantitative correction model established based on the algorithm combination achieved a prediction set coefficient of 0.868 2, and a root mean square error of 0.011 7 for Ganoderma lucidum spore powder samples with a sporoderm-broken rate range of 90%−100%. The selected optimal algorithm combination was applied to construct a quantitative correction model with a sporoderm-broken rate range of 0−100%, the coefficient of determination for the test set was 0.973 1 and the root mean square error was 0.049 3, showing good generalization ability. CONCLUSION The established quantitative detection model can realize the rapid and non-destructive detection of the sporoderm-broken rate of Ganoderma lucidum spore powder, which provides technical support for the quality control of Ganoderma lucidum spore powder and its products.
