Abstract

U 15 uzoraka hrane za dojenčad određivani su ugljikohidrati (glukoza, fruktoza, laktoza i saharoza). Metoda određivanja je visoko djelotvorna tekućinska kromatografija uz primjenu detektora indeksa loma. Udjel ugljikohidrata u proizvodu se kretao za fruktozu do 1,422 g/100 g proizvoda, za glukozu do 1,927 g/100 g proizvoda, za saharozu od 0,069 do 0,665 g/100 g proizvoda te za laktozu od 20,042 do 61,169 g/100 g proizvoda. Podaci dobiveni ovim istraživanjem su u skladu s Pravilnikom i literaturom, a ima odstupanja od podataka navedenih na deklaraciji proizvoda.

Abstract (english)

Carbohydrates (glucose, fructose, lactose and sucrose) were determined in 15 samples of infant formulae. The applied method for carbohydrate determination was High Performance Liquid Chromatography with usage of refractive index detector. The carbohydrate content in the analyzed products varied from non detected to 1,422 g/100 g for fructose, non detected to 1,927 g/100 g for glucose, from 0,069 to 0,665 g/100 g for sucrose and from 20, 042 to 61,169 g/100 g for lactose. Data obtained in this study are consistent with national regulations and data presented in literature but vary from the data on the declarations of the analysed products.
