Abstract
Cilj istraživanja bio je odrediti i usporediti fizikalno- kemijska svojstva, udjele vitamina C te senzorska svojstva u osam industrijski proizvedenih sokova jabuke: Fructal, Cappy, Fructal 100% bio jabolko, Rauch, Juicy, Fructal Superior, Velis jabuka, Eko zona. Vitamin C određen je tekućinskom kromatografijom visoke djelotvornosti (HPLC) uz UV PDA detekciju, a senzorska određivanja provedena su hedonističkom skalom. Rezultati provedenih analiza pokazali su da je udio vitamina C u industrijskim sokovima značajno varirao u ovisnosti o proizvođaču te je najmanja koncentracija od 0,03 mg/g soka određena u soku Cappy te najviša 42,38 mg/g u soku Fructal superior – 100% jabuka sok. Senzorska svojstva svih ocjenjivanih sokova bila su dobro ocjenjena s tim da je senzorski najprihvatljiviji i najharmoničniji bio sok Juicy (proizvođač Jamnica).
Abstract (english)
The objective of this work was to determine and compare physical and chemical properties, the quantity of vitamin C and sensory attributes in eight industrially manufactured samples of apple juice: Fructal, Cappy, Fructal 100% bio jabolko, Rauch, Juicy, Fructal Superior, Velis jabuka, Eko zona. Vitamin C was determined with high performance liquid chromatography (HPLC) with UV PDA detection and sensory analysis was conducted with hedonistic scale. The obtained results show that the concentration of vitamin C in industrial juices varied significantly depending on the manufacturer. The lowest concentration was determined in Cappy juice (0,03 mg/g) and the highest (42,38 mg/g) in Fructal superior – 100% apple juice. According to sensory analysis of all juices were acceptable, and the most acceptable and most harmonious was Juicy juice (producer Jamnica).
