Rapid determination method of hydroxymethyl furfural in honey by near infrared spectroscopy technique

The quantitative analysis model of hydroxymethyl furfural (HMF) in honey was built based on near infrared (NIR) spectroscopy technique and partial least squares (PLS) to determine HMF quickly. NIR spectrumswhich wavelength coverage chose 7706⁴009cm-1 were preprocessed with first derivate (SF) , Norris derivative smoothing and ten factors. The model was validated by cross-validation method. Results showed that Rcv2 was 0.99620, RMSECV was 2.40, Rp2 was 0.99874 and RMSEP was 2.02 in this model. NIR spectroscopy technique was applied to determine HMF quickly since there was no significant deviation between predictive values and determination values.
