Objective To study honey adulteration by near infrared spectroscopy-chemometrics method. Methods Transflectance mode with integrating sphere was used to collect NIR spectra. Savitzky-Golay first derivative method was employed to preprocess the raw NIR spectra. A Random Forest model was established based on the correlation between the NIR spectra and reference value. Results The prediction accuracy of the proposed method was 100% for training samples and 95% for test samples. Conclusion The proposed method is fast and non-destructive, and it provides a novel efficient and environmental friendly approach for the rapid qualitative detection of honey adulteration.
