Abstract

Humano mlijeko je po svom sastavu idealna hrana za prehranu dojenčadi. Iznimno, kada je dojenje iz opravdanih razloga onemogućeno, jedina adekvatna zamjena za prehranu dojenčadi su adaptirana mlijeka odnosno prema Pravilniku o početnoj i prijelaznoj hrani za dojenčad (NN 39/13), početna i prijelazna hrana za dojenčad. S obzirom da su dojenčad izrazito osjetljiva dobna skupina, nužne su redovite kontrole sastava, kvalitete i zdravstvene ispravnosti početne i prijelazne hrane za dojenčad. Proteini su od iznimne važnosti za njihov pravilan rast i razvoj, stoga je cilj ovoga rada bio odrediti udio proteina u uzorcima prijelazne hrane za dojenčad, usporediti ih s deklaracijama proizvoda i utvrditi jesu li analizirane vrijednosti u skladu s Pravilnikom o početnoj i prijelaznoj hrani za dojenčad (NN 39/13). Proteini su određeni metodom po Kjeldahlu direktno iz udjela dušika upotrebom Kjeltec uređaja. Udio proteina određen u svim ispitivanim uzorcima je u granicama propisanim pravilnikom, a utvrđena odstupanja od podataka na deklaracijama su u dozvoljenim granicama prihvatljivosti.

Abstract (english)

Human milk is the optimal food for infants. Exceptionally, when breastfeeding is for certain medical reasons prevented, adequate replacement for human milk is adapted milk produced under the regulations and called the infant and follow-on formula. Since infants and toddlers are particularly sensitive population group, regular monitoring of composition, quality control and foos safety are necessary. Proteins are extremely important for their growth and development, so the goal of this study was to determine the final protein content in samples of follow-on formulas and compare them with product labels and determine whether obtained results are in accordance with the regulations (NN 39/13). Proteins were determined by Kjeldahl method directly from nitrogen content using Kjeltec devices. Protein content of all analized samples is within the limits prescribed by the regulations and minimum deviation of the data are obtained in the declarations.
