Rapid and Accurate Identification of Gastrodia elata Blum Cultivar Based on FT-NIR Spectroscopy Combined with Chemometric Methods
In this study,a partial least squares discriminant analysis(PLS-DA) model and a residual convolution neural network(ResNet) model were constructed using Fourier transform near-infrared spectroscopy(FT-NIR) and two-dimensional correlation spectroscopy(2DCOS) technology,in conjunction with chemometric methods and deep learning algorithms,to rapidly and accurately identify three cultivated varieties of
Gastrodia elata
Blum(
G
.
elata
Bl.) samples(447). The results showed that the PLS-DA model,created by integrating first derivativ (1st Der) and multiple scatter correction(MSC) preprocessing of FT-NIR data,demonstrated the highest stability and the best overall performance,with an accuracy of 99.00%. At the same time,the identification method based on FT-NIR synchronous 2DCOS image combined with ResNet model could achieve rapid and accurate identification(100.00% accuracy) of different cultivars of
G. elata
Bl without the need for optimal pretreatment and complex data conversion. This study provides a rapid and accurate method for identifying different cultivars of
G. elata
Bl.,and lays a foundation for further germplasm resource research and breeding of new variety.
