Abstract
Visokoproteinski proizvodi danas su sve popularniji posebice kod mlade aktivne populacije. Predstavljaju brz i lako dostupan obrok bogat proteinima, najčešće konzumiran nakon tjelesne aktivnosti kao pomoć u sintezi proteina, odnosno u izgradnji mišićne mase. Problem predstavlja odgovarajuća kvaliteta proizvoda zbog mogućeg krivog navođenja količine proteina na deklaraciji. Stoga je cilj ovog rada bio odrediti udjel proteina u visokoproteinskim proizvodima te dobivene vrijednosti usporediti s onim navedenim na deklaraciji i provjeriti jesu li deklarirane prehrambene i zdravstvene tvrdnje u skladu s Uredbom (EZ) br. 1924/2006. Udjel proteina je određen metodom po Kjeldahlu u 43 visokoproteinska proizvoda komercijalno dostupna na hrvatskom tržištu. Dobivene vrijednosti udjela proteina svih analiziranih uzoraka su unutar vrijednosti odstupanja dozvoljenih od strane Europske Komisije. Osim toga, svi uzorci s deklariranim prehrambenim i zdravstvenim tvrdnjama su u skladu s Uredbom (EZ) br. 1924/2006.
Abstract (english)
In the present day, products rich in high protein content have gained considerable popularity, particularly among the active and youthful population. These products serve as convenient, readily accessible sources of nutrition, offering a swift and protein-rich meal option. They are frequently consumed following physical activities to aid in protein synthesis, contributing to the development of muscle mass. However, a concern arises regarding the product's actual protein quality due to potential inaccuracies in protein quantity indication on the packaging. As a result, the objective of this study was to assess the protein content in high protein products and subsequently compare the determined values with those specified on the product labels. Furthermore, an evaluation was conducted to ascertain whether the proclaimed nutritional and health claims align with the stipulations outlined in Regulation (EC) no. 1924/2006. The Kjeldahl method was employed to quantify the protein content in 43 distinct high protein products, all commercially available within the Croatian market. The results reveal that the measured protein content in all examined samples falls within the acceptable deviation limits established by the European Commission. Moreover, all products bearing declared nutritional and health claims demonstrate conformity with the provisions outlined in Regulation (EC) no. 1924/2006.
