USING THE NMR SPECTROSCOPY METHOD TO STUDY THE IDENTIFICATION AND ADULTERATION OF HONEY
Abstract
Abstract. The article deals with the issues of identification and falsification of honey by NMR spectroscopy. Honey is a natural sweet substance produced by Apis mellifera. It consists mainly of various sugars, mainly fructose and glucose, as well as other substances such as organic acids, enzymes and particulate matter obtained during honey harvesting. The main chemical constituent of honey is carbohydrates, which make up up to 95% of the dry weight, with fructose (38%) and a smaller portion of glucose (31%) being the main sugar components among the 22 different sugars present in honey. Geographical and botanical origin are factors that dictate the price of this widely consumed natural product. The economic benefits have made honey an easy target for adulteration, including deliberate mislabeling of honey origin, adding water and sugar to honey, and feeding bees excessive amounts of artificial syrup during the nectar collection period. Thus, honey identification is an urgent problem. Nuclear magnetic resonance (NMR) techniques are widely recognized as an important tool for food analysis, as they allow us to study both the chemical composition and molecular dynamics of food matrices.
