Abstract

U radu je ispitana prihvatljivost bezalkoholnih napitaka na bazi voćnog soka naranče s dodatkom odnosno smanjenjem određenih hranjivih i drugih tvari u količini koja udovoljava kriteriju za određenu tvrdnju prema Pravilniku o prehrambenim i zdravstvenim tvrdnjama, a koji su laboratorijski pripremljeni i označeni uzimajući u obzir odredbe posebnog propisa o voćnim sokovima koje se odnose na dopuštene sastojke u proizvodnji. Uz ispitivanje prihvatljivosti standardnih napitaka, ispitivala se prihvatljivost četiri napitka označena s po jednom prehrambenom te dva napitka označena s po jednom zdravstvenom tvrdnjom. Uz prethodno provedeno kvalitativno ispitivanje, glavno, kvantitativno ispitivanje provelo se dva puta: bez pružanja informacije ispitanicima o tome što se ispituje te sa informacijom o nazivu proizvoda i prehrambenoj odnosno zdravstvenoj tvrdnji. Rezultati su pokazali da prihvatljivost bezalkoholnih napitaka najviše ovisi o okusu, bez obzira na navedenu tvrdnju, ali i da tvrdnja može utjecati na prihvatljivost pozitivno ukoliko organoleptička kvaliteta proizvoda nije značajno narušena odnosno ukoliko nisu prisutni neprijatni okusi, nekarakteristični za kategoriju hrane koja se ispitivala.

Abstract (english)

This thesis determines the acceptability of non-alcoholic beverages based on orange fruit juice with either the addition or reduction of specific nutrients and other substances in the quantity that meets the criteria for a particular claim under the Regulations on nutrition and health claims, which are laboratory prepared and marked, taking into consideration the provisions of a special regulation on fruit juices related to authorised ingredients in the production. Along with the determination of the acceptability of standard beverages, the determination of the acceptability of four beverages marked with one nutrition claim and two beverages marked with one health claim, was performed. With the previously conducted qualitative determination, the main part of the determination, a quantitative determination, was conducted twice: without providing information on beverages that are being tested and with information on the full product name and nutrition or health claim. The results showed that the acceptability of non-alcoholic beverages mostly depends on taste, regardless of a claim by which it was marked, but the claim can positively affect the acceptability if the organoleptic quality of the product is not significantly affected, if unpleasant flavours, uncharacteristic for a category of food that was examined, were not present.
