Summary

A new method for the semiautomatic determination of 5-hydroxymethylfurfural (HMF) by photometric flow injection analysis on the basis of the Winkler's reaction is proposed. The derivative FIA-gram signals were also obtained and detection limit was decreased. The linear range of determination is 2.3–98 μg·ml−1. The presence of sugars is well tolerated. The proposed method can be employed to determine HMF in honey samples with a sampling frequency of 35 h−1.
