Abstract
Cilj ovog rada bio je ispitati utjecaj različitih antioksidanasa i biljnih ekstrakata (mješavina tokoferola, askorbil palmitat, tri različita tipa ekstrakta ružmarina, ekstrakt zelenog čaja i ekstrakt sjemenki grožđa) na stabilnost i organoleptička svojstva hrskavih žitarica proizvedenih u laboratorijskim uvjetima. Crunchy muesli je zapakiran i čuvan 12 mjeseci pri sobnoj temperaturi i pri 37 °C. Stabilnost proizvoda praćena je određivanjem peroksidnog broja i kiselinskog stupnja (svakih 30/60 dana). Prema rezultatima proračuna % inhibicije dobivenog na temelju peroksidnog broja vidljivo je da najjače antioksidativno djelovanje posjeduje ekstrakt ružmarina, međutim zbog izraženih začinskih organoleptičkih karakteristika koje dolaze do izražaja i u samom proizvodu nije prikladan za primjenu u ovom tipu proizvoda. Nakon ekstrakta ružmarina zadovoljavajući učinak imao je i ekstrakt zelenog čaja koji je dovoljno snažan da održi trajnost proizvoda u trajanju od najmanje 12 mjeseci.
Abstract (english)
The aim of this research was to examine the influence of different antioxidants and plant extracts (tocopherol mixture, ascorbyl palmitate, three different rosemary extracts, green tea extract and grape seed extract) on the stability and organoleptic properties of crunchy muesli produced in laboratory conditions. Crunchy muesli was packed and stored at room temperature and at 37 °C. Product stability was monitored through peroxide value and acid number (every 30/60 days). Calculated inhibition percentage (based on peroxide value) indicated that rosemary extract had highest antioxidant activity, but it also gave significant aroma to the product due to which it is not suitable for this application. Satisfactory antioxidant activity was determined for the green tea extract, which was potent enough to preserve the product for minumum 12 month.
