Aromatične spojine jagod (Fragaria x ananassa Duch.) : diplomsko deloPenič, KatarinaJagodam daje skladen in na splošno všečen okus razmerje sladkorjev ter organskih kislin. Poleg tega so v plodovih prisotne tudi hlapne (aromatične) spojine, ki se izločajo med zorenjem in pomembno ... prispevajo h končni aromi dozorelih jagod. V sklopu tega zaključnega dela smo ugotavljali, katere posamezne aromatične snovi dajejo jagodam značilno aromo. Raziskovanje je potekalo na Kmetijskem inštitutu v Ljubljani od leta 2020 do leta 2022. Na podlagi validirane metode smo določali vsebnost posameznih izbranih aromatskih spojin jagode s pomočjo metode SPME v sklopu plinske kromatografije (GC-MS) za merjenje vsebnosti hlapnih komponent. Uspešno smo potrdili prisotnost 15 različnih aromatičnih spojin, razdeljenih v 5 skupin (aldehidi, estri, alkoholi, terpenoidi in ketoni). Identificirali smo 6 estrov (metil-2-metilbutirant, etil-2-metilbutirant, etil-izovalerat, metil heksonat, metil oktanoat in oktil acetat), 3 alkohole (trans-2-heksen-1-ol, cis-2-heksen-1-ol in 1-penten-3-ol), 3 terpenoide (geraniol, α-terpinol in nerolidol), 2 aldehida (trans-2-heksen-1-al in heksanal) in 1 keton (2-heptonanon). S pridobljenimi podatki, ki smo jih ustrezno obdelali, smo ugotovili, da so v jagodah sorte 'Clery' prisotne v največjem deležu hlapne snovi iz skupine aldehidov (predstavljajo 67,4 % vseh identificiranih hlapnih spojin) in da prevladujejo arome iz skupine estrov, ki dajejo okusu sadno notoType of material - undergraduate thesisPublication and manufacture - Maribor : [K.
