Abstract

Cilj istraživanja bio je ispitati stabilnost minimalno procesirane jabuke skladištene osam dana pri kontroliranom sastavu atmosfere. Svježe jabuke sorte Cripps Pink su se oguljene i narezane čuvale u uvjetima modificirane atmosfere pri temperaturi između 4 i 6 ºC. Ispitivanje je provedeno na temelju mjerenja promjena boje i teksture, uzimanjem uzoraka za analizu prvi, drugi, treći, peti i osmi dan. Određivanje boje vršilo se difuzno reflektirajućom spektrofotometrijom na kolorimetru CM-3500d, a teksture na TA.HD Plus analizatoru. Dobiveni rezultati su pokazali pozitivan učinak snižene temperature i kontroliranog sastava atmosfere na održivost skladištene jabuke.

Abstract (english)

The aim of this study was to examine the stability of minimally processed apples stored in controlled atmosphere for eight days. Peeled and sliced (fresh cut) apples Cripps Pink were kept under controlled atmosphere at a temperature between 4 and 6 ºC. Monitoring was based on measurment of changes in colour and texture, taking samples for analyisis on the first, second, third, fifth and eighth day. Colour determination was performed with diffusive reflective spectrophotometry using colorimeter CM-3500d, and texture determination using TA.HD Plus analyzer. The results showed a positive effect of controlled atmosphere on the stability of stored apples.
