Kakovost jabolk cv. zlati delišes, gloster, ajdared in jonagold po skladiščenju : diplomska naloga = Quality of apples cv. Golden delicious, Gloster, Idared and Jonagold after storage : graduation thesis
Beber, Mirjam
V diplomski nalogi smo želeli ugotoviti kakovost jabolk cv. Zlati delišes. Gloster, Ajdared in Jonagold po končanem skladiščenju v normalni atmosferi (NA). Jabolka so bila obirana v tedenskih ...intervalih v treh sadovnjakih: Prevoje, Podvin in Biotehniška fakulteta v Ljubljani. Opravili smo analize vsebnosti suhe snovi, skupnih kislin, izraženih kot jabolčna, trdote mesa plodov, osnovne barve kožice (eksokarpa) ter senzorično analizo. Suho snov (v %) smo določili s pomočjo digitalnega refraktometra direktno v iztisnjenem soku. Skupne kisline smo določili s potenciometrično titracijo z 0,1 N NaOH (g/kg). Trdoto mesa plodov (v k/cm2) smo izmerili s penetrometrom, barvo kožice pa s pomočjo kromametra Minolta s sistemom L, a, b. Senzorično smo ocenjevali kislost, sočnost in aromo jabolk. Vsebnost suhe snovi z zorenjem narašča, kar se kaže tudi po skladiščenju. Trdota mesa plodov pada. Pada tudi vrednost -a (bolj zelena / manj rdeča ), razen pri Zlatem delišesu. Senzorično so najbolje ocenjena zadnja obiranja. Večje razlike med sadovnjaki so samo pri rezultatih vsebnosti suhe snovi.
