USPOREDBA HRVATSKOG I MAKEDONSKOG MEDLJIKOVCA

The aim of this research was to compare physicochemical characteristics of honeydew honeys originating from Croatia and Macedonia. 11 samples of Macedonian and 17 samples of Croatian honeydew honey were collected during the harvest season 2005 and 2006, respectively. All collected samples were subjected to the melissopalynological analysis, and afterwards physicochemical characteristics were determined. In comparison with Croatian samples, the samples of Macedonian honeydew honey show statistically significant higher electrical conductivity, prolin content, free and total acidity, glucose and sucrose, as well as fructose and glucose content (F + G), and lower specific rotation, almost negative values. Croatian samples have higher content of maltose (with celobiose and trehalose) and raffinose, until melezitose (with erlose) content in both sample groups is low.Zadatak ovog istraživanja bio je usporedba fizikalno-kemijskih parametara medljikovca podrijetlom iz Hrvatske i Makedonije. Prikupljeno je 11 uzoraka proizvedenih u Makedoniji 2005. i 17 uzoraka proizvedenih u Hrvatskoj 2006. godine. Po provedenoj melisopalinološkoj analizi, određeni su fizikalno-kemijski parametri uzoraka. U usporedbi s hrvatskim uzorcima, makedonski uzorci pokazuju statistički značajno višu električnu provodnost, udio prolina, slobodnu i ukupnu kiselost, udio glukoze i saharoze, udio fruktoze i glukoze (F + G), te nižu specifičnu rotaciju, uglavnom negativnu. Hrvatske uzorke karakterizira viši udio maltoze (sa celobizom i trehalozom) i rafinoze, dok je udio melecitoze (sa erlozom) u obje skupine uzoraka nizak
