FIELD: food industry; measurement.SUBSTANCE: one selects samples of buckwheat 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 buckwheat honey; honey is considered to be fresh if glucose and fructose content stays within the ranges of 26.5-28.9 wt % and 30.8-32.7 wt % respectively while acidity and diastase number stay within the ranges of 2.6-4.1 cm0.1 N NaOH per 100 g of honey and 45-52 units Gotha respectively.EFFECT: enhancement of accuracy, reproducibility, validity and reliability of determination.2 ex |
