Physico-chemical senzoric attributes and phenolic compositions of fresh and processed strawberries
U ovom radu ispitivan je fizikalno ā kemijski sastav jagoda sorti Clery, Honeoye i NF 421 te su od njihovih kaÅ”a pripremljene niskokaloriÄne marmelade. OdreÄeni su ukupni fenoli, neflavonoidi, flavonoidi, antocijani te antioksidativna aktivnost DPPH metodom. Metodom kvantitativne deskriptivne analize ocijenjena su senzorska svojstva svježih plodova, kaÅ”a jagoda i marmelada navedenih sorti. Marmelade su kuhane u vakuum kuhaÄu i pri atmosferskom tlaku u laboratorijskim uvjetima. U analiziranim kaÅ”ama utvrÄena je razlika u koliÄini ukupne suhe tvari, topljive suhe tvari i pH vrijednosti. Preradom kaÅ”a u marmelade doÅ”lo je do smanjenja koliÄine antocijana, ali to nije utjecalo na smanjenje antioksidativne aktivnosti. Svježi plodovi jagoda sorti NF 421 i Clery imale su bolje ocijenjenu slatkoÄu i harmoniju okusa. KaÅ”a sorte Honeoye imala je kiseliji okus, intenzivniju aromu po voÄu, jaÄi intenzitet mirisa i miris po jagodama od sorti Clery i NF 421. Marmelade kuhane u vakuum kuhaÄu ocijenjene su vrlo sliÄno.In this paper the analysis of physical and chemical compositions of strawberry cultivars Clery, Honeoye and NF 421 were determined and the low calory marmelades were prepared. The total phenolic, flavonoid, non-flavonoid, anthocyanin contents and antioxidative activity were determined in the mash and marmelades. Using quantitative descriptive analysis sensor attributes of fresh strawberries, their purees and marmelades were determined. Marmelades are prepared under vacuum conditions and under atmosphere pressure in laboratory conditions. Total soluble solids and pH values were different in the analyzed purees from the source. During the processing of purees into marmelades the amount of total anthocyanins was decreased but there was no influence on the antioxidative activity, which was quite remarkable. Fresh strawberries Clery and NF 421 had better sweetness and flavour marks. Puree made of strawberry Honeoye had a more sour taste, more intensive strawberry flavour, bigger intensity of flavour and friut aroma than the purees made of strawberries Clery and NF 421. Marmelades prepared under vacuum conditions were almost similar
