    THE INFLUENCE OF ALTITUDE ON THE QUALITY OF HONEY IN CENTRAL SERBIA
    (University of East Sarajevo, Faculty of Agriculture, Republic of Srpska, Bosnia University of Belgrade, Faculty of Agriculture, Serbia Mediterranean Agronomic Institute of Bari (CIHEAM - IAMB) Italy, 2023-10-05) Jevtić, Goran; Babić, Snežana; Andjelković, Snežana; Lazarević, Đorđe; Petrović, Mirjana; Matović, K; Nedić, N
    The paper analyzed acacia, meadow and forest honey (honeydew) from Central Serbia. The parameters of honey quality were determined according to the methods of the Rulebook on the quality of honey and other bee products (Official Gazette of RS, 2015). Total nitrogen was determined by the micro-Kjeldahl method, and potassium and trace elements were determined by the AAS-method. In the case of acacia honey, the acidity and amount of mineral substances (ash) increase with the increase in altitude, while the amount of sugar (total, reducing and saccharose) and water decreases. The increase in altitude also had an impact on the quality parameters of meadow honey. With the increase in altitude, the amount of mineral substances and water in this honey increases, while the total sugars and sucrose decrease. The amount of analyzed macro and micro elements in meadow honey increased with altitude, with the exception of zinc (Zn). Honeydew from the hill area had the most ash and the lowest values for other parameters. In this honey, all minerals reach their maximum in the hilly area, and decrease in the plain and mountainous area. The exception is zinc (Zn), which is most abundant in honey from the plains. All analyzed honeys met the conditions prescribed by the Rulebook on the quality of honey (Serbia) and the Directives on the quality of honey in the European Union.
