Determination of furanic compounds and acidity for Italian honey quality
The quality of honey is influenced by botanical origins and acidity. 5-Hydroxymethyl-2-furaldehyde (HMF) is a well-monitored indicator for freshness and quality, whereas no restriction is reported for 2-furfural. The aim of the study is the determination of these compounds in 21 Italian honey samples through high-performance liquid chromatography (HPLC). In order to validate the HPLC method, the detection and quantification limits (LOD and LOQ, respectively), recovery, precision (repeatability), and linearity were determined.
