Abstract

Cilj ovog istraživanja bio je određivanje kalcija i magnezija prisutnih u bagremovom i cvjetnom medu prikupljenom od hrvatskih pčelara. Istraživanje je provedeno na deset uzoraka bagremovog i deset uzoraka cvjetnog meda. Uzorci su tretirani tehnikom „suhog“ spaljivanja, nakon čega su podvrgnuti mineralizaciji u mufolnoj peći. Udio kalcija i magnezija određen je na atomskom spektrofotometru Perkin-ELMER 2380. Dobiveni rezultati ukazuju na značajno veću količinu prisutnih mineralnih elemenata u cvjetnom medu, u usporedbi sa bagremovim. Takvi rezultati su u korelaciji s podacima iz literature, koji navode da tamniji medovi imaju veću koncentraciju minerala od svijetlih medova. Izmjerene koncentracije kalcija i magnezija bile su približne drugim provedenim istraživanjima na području Hrvatske.

Abstract (english)

The goal of this research was to determine calcium and magnesium content of black locust and medow honey collected from Croatian beekeepers. Research was done on ten samples of black locust honey and ten samples of medow honey. Samples were treated with „dry“ burning method after which they were subjected to mineralization in muffle furnace. Calcium and magnesium was determined with atomic absorption spectrometer Perkin-ELMER 2380. Obtained results indicate that there is a larger amount of mineral elements in medow honey in comparison to black locust honey. This results are in correlation with results in literature from which we can conclude that dark honeys have a higher mineral content than pale ones. Measured concentration of calcium and magnesium were close to those measured in other research in Croatia.
