Abstract

The scope of this investigation is the development and application of a sensor array food profiling method. The method relies on neural network model development for probiotic fermented milk classification according to flavor, rapid determination of probiotic fermented milk aroma compounds and accurate prediction of the results from a trained sensory panel. The newly developed method would be applied to a new matrix as to present the potential of the method in food quality control and analysis. Therefore a rapid method for simultaneous honey physico-chemical characterization and botanical classification would be developed.

Abstract (croatian)

Cilj ovog rada je razvoj i primjena metode niza potenciometrijskih senzora u svrhu karakterizacije probiotičkih jogurta. Temelji se na razvoju modela neuronskih mreža za klasifikaciju probiotičkog jogurta prema okusu, brzom određivanju komponenata arome te za predviđanje rezultata senzorskog panela s velikom preciznošću. Svrha rada je također i primjena novo-razvijene metode na drugi analit kako bi se prikazao potencijal metode u analizi i kontroli kvalitete prehrambenih proizvoda. U tu je svrhu odabran med te je pomoću elektroničkog jezika omogućena brza fizikalno-kemijska karakterizacija te klasifikacija uzoraka meda prema botaničkom podrijetlu.
