dc.description.abstractPredmet istraživanja u okviru ove disertacije bila je karakterizacija odabranih uzoraka najzastupljenijih vrsta monofloralnog meda (meda od bagrema, od lipe i od suncokreta) na osnovu njihovog mineralnog sastava, kao i klasifikacija i diferencijacija prema njihovom botaničkom i geografskom poreklu primenom hemometrijskih tehnika. Ispitano je ukupno 206 uzoraka pet različitih botaničkih vrsta (162 uzoraka meda od bagrema, 11 uzoraka meda od lipe, 23 uzorka meda od suncokreta, 7 uzoraka meda od uljane repice i 3 uzorka meda od bosiljka), sakupljenih iz šest različitih regiona Srbije. Ova studija je pružila osnovne informacije o sadržaju dvanaest makro i mikroelemenata i elemenata u tragovima (K, Ca, Mg, Na, Cu, Zn, Fe, Mn, Co, Cd, Cr i Ni) u izvornom srpskom medu. Sadržaj metala je određen primenom induktivno spregnute plazme - optičke emisione spektrometrije (ICP – OES). Mineralni markeri za deklarisanje autentičnosti tri glavne vrste monofloralnog meda (bagremovog, lipovog i suncokretovog), u smislu njihovog botaničkog i geografskog porekla, su ustanovljeni primenom hemometrijskih tehnika - analize glavnih komponenata (PCA) i metode delimičnih nаjmаnjih kvаdrаtа sa diskriminantnom analizom (PLS-DA). Najvažniji elementi za diskriminaciju između uzoraka poreklom od ove tri botaničke vrste su kalijum, kalcijum i magnezijum. Na klasifikaciju lipovog meda najveći pozitivan uticaj ima sadržaj kalijuma, dok model za suncokretov med ukazuje na pozitivne vrednosti regresionih koeficijenata za kalcijum i magnezijum, a negativne vrednosti za kalijum. U skladu sa sastavom zemljišta, model za bagremov med naglašava pozitivan uticaj nikla, kobalta, hroma i kadmijuma, a suprotan uticaj kalijuma, kalcijuma i magnezijuma. Mogućnost diferencijacije meda po regionalnom poreklu proverena je na statistički značajnom broju uzoraka meda od bagrema. Dobijeni PCA model je pokazao da prisustvo minerala i elemenata u tragovima u ovoj vrsti meda uglavnom zavisi od same biljne vrste i njene specifične tendencije za bioakumulaciju pojedinih elemenata, a ne od tipa i sastava zemljišta...sr
dc.description.abstractThe subject of the research in this dissertation was the characterization of selected samples of the most common types of monofloral honey (acacia, linden and sunflower honey) based on their mineral composition, as well as classification and differentiation according to their botanical and geographical origin using chemometric techniques. A total of 206 samples of five different botanical species were examined (162 acacia honey samples, 11 linden honey samples, 23 sunflower honey samples, 7 rape honey samples and 3 basil honey samples), collected from six different regions of Serbia. This study provided basic information on the content of twelve macro and microelements and trace elements (K, Ca, Mg, Na, Cu, Zn, Fe, Mn, Co, Cd, Cr and Ni) in the genuine Serbian honey. The metal content was determined by inductively coupled plasma - optical emission spectrometry (ICP - OES). Mineral markers for declaring the authenticity of the three main types of monofloral honey (acacia, linden and sunflower) in terms of their botanical and geographical origin have been established using chemometric techniques – principal component analysis (PCA) and partial least square – discriminant analysis (PLS-DA). The most important elements for discrimination between samples originating from these three botanical species are potassium, calcium and magnesium. Potassium content has the most positive effect for the classification of linden honey, while the sunflower honey model indicate positive values of regression coefficients for calcium and magnesium, and negative values for potassium. In accordance with the soil composition, the model for acacia honey emphasize the positive influence of nickel, cobalt, chromium and cadmium, and the opposite influence of potassium, calcium and magnesium. The possibility of differentiating honey by regional origin was tested on a statistically significant number of acacia honey samples. The obtained PCA model showed that the presence of minerals and trace elements in this type of honey mainly depends on the botanical species and its specific tendency for bioaccumulation of certain elements, not on the type and composition of the soil. The results for the content of trace minerals and metals, as well as basic physical-chemical parameters in basil honey were presented in this study...en
