Abstract
Sportaši, fitness entuzijasti i općenito tjelesno aktivne osobe kao jedne od najčešće korištenih dodataka prehrani koriste dodatke proteina. Posežu za njima iz više razloga, kao što su poboljšanje izvedbe, promicanje snage mišića i veličine, često ne informirajući se dovoljno o njima. Potrošnja proteinskih dodataka koja je u konstantnom rastu može predstavljati problem zbog zabrinutosti za njihovu kvalitetu. Stoga je cilj ovoga rada bio odrediti udjel proteina u uzorcima visokoproteinskih prahova, usporediti ih s deklaracijama proizvoda i utvrditi jesu li dobivene vrijednosti u skladu sa Uredbom (EZ) br. 1924/2006 o prehrambenim i zdravstvenim tvrdnjama koje se navode na hrani. Proteini su određeni metodom po Kjeldahlu direktno iz udjela dušika upotrebom Kjeltec uređaja, u 10 uzoraka visokoproteinskih proizvoda životinjskog i biljnog podrijetla, stranih i domaćih proizvođača, dostupnih na hrvatskom tržištu. Udjel proteina određen u svim analiziranim uzorcima je u granicama određenim Uredbom, a utvrđena odstupanja od podataka na deklaracijama su u dozvoljenim granicama prihvatljivosti propisanih Hrvatskom agencijom za hranu.
Abstract (english)
Athletes, fitness enthusiasts and active people use protein supplements as one of the most commonly used dietary supplements. They reach for them for a number of reasons, such as enhancing performance, promoting muscle strength and size, often not informed enough. The consumption of protein supplements that is constantly growing may be a problem due to concerns about their quality, so the aim of this work was to determine protein content in high protein powders, compare them with product declarations and determine whether values were in accordance with national regulations (EZ) no.1924/2006. The proteins were determined by Kjeldahl method directly from the nitrogen content using the Kjeltec device, in 10 high protein samples of animal and plant origin, foreign and domestic producers, available on the Croatian market. The protein content determined in all samples is within the limits established by regulations and the deviations are within limits prescribed by the Croatian Food Agency.
