Determination of Botanical and Geographical Honey origin by Electronic nose

Determination of honey botanical origin is essential factor that is required prior entering any market, and it is factor that dictates price. Problems associated with botanical origin determination are rooted in fact that required analyses (pollen analysis, physicochemical parameters determination and sensory analysis) are arduous and time consuming. This work examines performance of electronic nose based on 12 MOS and 10 MOSFET sensors in classification of different honey samples collected in Croatia with respect to their botanical and geographical origin. Data analysis is performed with StatSoft Statistica 7 software package using modules for PCA (NIPALS algorithm) and ANN. Classification results clearly demonstrates ability of electronic nose to distinguish different types of honey, and within same honey type differences that can be correlated with geographical origin.
