Sensory evaluation of different apple juices

Na Univerzitetnem kmetijskem centru Pohorski dvor Fakultete za kmetijstvo in biosistemske vede Univerze v Mariboru smo v letu 2018 pridelali sok različnih sort jabolk. V okviru zastavljenega poskusa smo na sejmu AGRA v Gornji Radgoni leta 2019 izvedli hedonsko senzorično ocenjevanje sokov sort jabolk \u27Jonagold\u27, \u27Zlati delišes\u27, \u27Idared\u27, \u27Braeburn\u27 ter sok iz dveh odpornih sort Topaz\u27 in \u27Opal\u27. Preskuševalci so ocenjevali sokove glede na všečnost barve, vonja, okusa in podali skupno oceno. Najvišjo skupno oceno sta prejela sokova iz sort jabolk \u27Braeburn\u27 in \u27Idared\u27, najnižjo pa sok iz jabolk sort \u27Topaz\u27 in \u27Opal\u27. Preskuševalcem moškega spola je bil najbolj všeč sok iz sorte jabolk \u27Idared\u27, ki je manj sladek, ženskam pa slajši in bolj aromatičen sok iz jabolk sorte \u27Zlati delišes\u27. Preskuševalcem, starim do 25 let, je bil najbolj všeč sok iz jabolk sorte \u27Braeburn\u27, ki ima izrazitejšo kislino in robustnejši okus. Preskuševalcem, starim med 26 in 65 let, pa je bil bolj všeč sok iz jabolk sorte \u27Jonagold\u27, ki je blažjega in slajšega okusa z močno izraženo aromo. Najstarejši skupini preskuševalcev, nad 65 let, je bil najbolj všeč sok iz jabolk sort \u27Topaz\u27 in \u27Opal\u27. Ti dve sorti sta odporni, primerni za ekološko pridelavo in zato nekoliko robustnejši v okusu, imata agresivnejšo kislino ter izrazit okus in aromo, hkrati pa spominjata na stare sorte iz travniških nasadov.In 2018, at the UKC Pohorski dvor, Faculty of Agriculture and Life Sciences in Maribor, we produced juices from different varieties of apples. At the AGRA fair in Gornja Radgona in 2019 we performed a hedonic sensory evaluation of juices of the \u27Jonagold\u27, \u27Golden Decilious\u27, \u27Idared\u27 and \u27Breaburn\u27 varieties and the resistant, \u27Topaz\u27 and \u27Opal\u27 varieties. The evaluators ranked the juices by color, smell and taste, and gave an overal evaluation. Juices of the \u27Braeburn\u27 and \u27Idared\u27 variety were ranked highest, while juice of \u27Topaz\u27 and \u27Opal\u27 variety were ranked lowest. Male evaluators ranked the less sweet \u27Idared\u27 variety juices the highest, while females perferred the sweeter and more aromatic \u27Golden Delicious\u27 juice variety. Evaluators aged under 25 prefered juice of the \u27Breaburn\u27 variety, which is more sour and strong in taste, while the group aged between 26 and 65 preferred the \u27Jonagold\u27 juice, which is of a smooth and sweet taste with a stronger aroma. Evaluators aged 65 and more ranked the juice of resistent varieties \u27Topaz\u27 and \u27Opal\u27 the highest. These varieties, are suitable for organic production and therefore have a somewhat stonger taste with a prononunced bitternes and acidity, very similar to the taste of old varieties used in meadow orchards
