5-Hydroxymethyl furfural determination in Italian honeys by a fast near infrared spectroscopy
The determination of 5‑hydroxymethylfurfural (HMF) content in honey samples of different botanical origin by a NIR-chemometrics-based approach is reported. Spectral regions, statistical models, scatter and derivative correction together with smoothing pre-treatment were examined and selected on the basis of correlation coefficient and root mean square errors for both the calibration (R2cand RMSEC) and cross-validation (R2vand RMSECV).
