Sensory Evaluation of Fruit of Some Scab Resistant Apple Varieties

Fruit quality of five scab resistant apple cultivars (Enterprise, Liberty, Nova Easygro, Sir Prize and Rewena) suitable for organic growing systems were tested. External and internal fruit quality was assessed through standard parameters (fruit weight, firmness, soluble solids, malic acid) and sensorial quality by panel tests (fruit size, shape and colour; hardness, texture, juiciness, sweet/acid taste, aroma and overall flavour). Large differences in sensory scores for particular quality attributes were found between cultivars. The hedonic scores showed significantly lower preference for tested scab resistant apple cultivars in comparison to ‘Jonagold’ as the reference cultivar.
Istraživana je kakvoća plodova pet sorata jabuke, koje su zbog otpornosti na čađavu krastavost prikladne za sustav organske proizvodnje. Istraživanjima su obuhvaćene sorte Enterprise, Liberty, Nova Easygro, Sir Prize i Rewena. Kakvoća plodova utvrđena je standardnim metodama, pri čemu su kao vanjski parametric kakvoće utvrđeni: masa ploda, tvrdoća mesa ploda, sadržaj topive suhe tvari i ukupnih kiselina. Senzoričko vrednovanje, na osnovi panel testa, uključilo je: veličinu ploda, oblik i boju, tvrdoću, teksturu, sočnost, omjer šećera i kiselina, te aromu i ukupnu senzoričnu vrijednost. Nađene su značajne razlike između sorata glede senzoričnih ocjena. Ukupno gledano, istraživane sorte su, u odnosu na standardnu sortu Jonagold, postizale lošije ocjene.
