Abstract:
Objective: To establish the qualitative analysis model for Guang Citrus Reticulata Pericarpium (GCRP) using near infrared spectroscopy, so as to establish a rapid method to identify GCRP. Methods: After collecting the near-infrared spectra of GCRP and Chuan Citrus Reticulata Pericarpium (CCRP), standard orthogonal variable transformation (SNV) was used as pretreatment and cluster analysis method was used to establish identification models. The model validation and external validation were made, and a GCRP analysis model was established using near-infrared spectroscopy technology. Results: In wavelength range of 4000-10000 cm-1, GCRP was able to be distinguished. The accuracy rate of internal validation was 100% and the accuracy rate of external validation was 90.91%. Conclusion: It is feasible to identify GCRP samples by near infrared spectroscopy technique.
