Abstract Assay of Maillard reaction products (e.g. furosine) is a reputable method for determination the honey freshness. In this report, novel optical technique proposed real-time measurement changes furosine content in honey. The based on unidirectional energy transfer between two peaks doubled-peak fluorescence spectrum as secondary inner filter effect (2nd-IFE) specific arrangement laser induced (LIF) setup. Proper parameters are defined accordingly, and affirmed to be dependent It shown that introduced not sensitive LIF intensity fluctuations by ambient noises particularly alter due 2nd-IFE. Furosine level 8 types with different botanical origin were chemically determined before after 1 year storage, compared values devised spectral parameters. Proofs conducted can utilized evaluation
