FIELD: food industry; measurement.;SUBSTANCE: one selects samples of sunflower honey, determines glucose and fructose content in the samples by way of a highly efficient liquid chromatography method, additionally one determines total acidity and diastase number and, per the totality of the said indices, one estimates freshness (age) of sunflower honey; honey is considered to be fresh if glucose and fructose content stays within the ranges of 30.6-33.0 wt % and 34.1-36.3 wt % respectively while acidity and diastase number stay within the ranges of 1.8-2.3 cm3 0.1 N NaOH per 100 g of honey and 19-26 unit Gotha respectively.;EFFECT: enhancement of accuracy, reproducibility, validity and reliability of determination.;2 ex
