Abstract

Metabolomika je nova znanstvena disciplina koja proučava kemijske i biokemijske procese koji se tiču cjelokupnog staničnog metaboloma. Spregnuta sa spektroskopijom NMR predstavlja dobru alternativu brojnim analitičkim metodama korištenima u analitici prehrambenih proizvoda. Med je izrazito vrijedna i cijenjena namirnica u cijelom svijetu. Zbog svojih vrijednih svojstava sve je češće predmet krivotvorenja i lažnog deklariranja botaničkog i geografskog porijekla. Analizom uzoraka meda iz različitih zemalja (Novi Zeland, Brazil, Finska i Kina) spektroskopijom NMR utvrđeni su specifični biomarkeri svih analiziranih botaničkih vrsta. Pomoću tih markera uspješno je utvrđeno botaničko porijeklo analiziranih medova koristeći se statističkom obradom podataka.

Abstract (english)

Metabolomics is a new scientific discipline that studies chemical and biochemical processes related to whole cell metabolism. In combination with NMR spectroscopy, it provides a good alternative to a number of analytical methods used in food analysis. Due to its valuable properties, honey is increasingly subject of counterfeiting and false claims of botanical and geographical origin. By analyzing honey samples from different parts of the world (New Zealand, Brazil, Finland and China) using NMR spectroscopy, it was possible to determine specific biomarkers of all botanical species were studied. Based on these markers, the botanical origin of the analyzed honeys could be successfully distinguished using statistical data processing.
