Abstract (croatian)
Cilj ovog rada bio je ispitati kinetiku ekstrakcije polifenola tijekom priprave različitih čajeva. Korišteni su zeleni čaj, čaj od kamilice, čaj od šipka i hibiskusa, te čaj od čistog šipka. Sve vrste čaja podvrgnute su ekstrakciji u trajanju od 3, 6 i 9 minuta. Određena je gustoća boje, antioksidativna aktivnost, te ukupni sadržaj polifenola. Rezultati su pokazali da uvjeti tijekom pripreme čajeva, imaju značajan utjecaj na sadržaj polifenola. Zeleni čaj, pri ekstrakciji u trajanju od 9... More minuta, imao je najveću antioksidativnu aktivnost i sadržaj ukupnih polifenola. Less
Abstract (english)
The object of this work was to determine the kinetics of polyphenol extraction during preparation of different teas. Commercial green tea, chamomile tea, rosehip and hibiscus tea and rosehip tea were used as samples. Each tea has been extracted for 3, 6 and 9 minutes. Colour density, antioxidant activity and total polyphenol content were determined. Results have shown that conditions of tea preparation, had significant influence on polyphenol content. Green tea, extracted for 9 minutes,... More had the highest antioxidant activity and total polyphenol content. Less
