[en] The quality of honey is established by its botanical or floral origin and chemical
composition. Sugar spectrum is an important criterion for authenticity determination. High fructose
content is a characteristic of locust honey. 64 honey samples originating from three different zones
of Romania were investigated for sugar spectrum and water content in order to establish the
botanical origin declared by the suppliers. Excepting few samples (3), all other honeys were in the
range of standard values for water content, fructose, glucose and other sugars. Different calculated
parameters (fructose/glucose F/G ratio, glucose/water G/W ratio and (glucose-water)/fructose (G-
W)/F ratio) were used also for honey authentication.
