Chemical composition of apple cider : a comparative study of Norwegian and French ciders
Ingunn Ovsthus, Mitja Martelanc, Tatjana Radovanović, Marko Lesica, Lorena Butinar, Branka Mozetič Vodopivec, Guillaume Antalick, 2023, published scientific conference contribution

Abstract: Norwegian apple ciders have recently gained attention at the levels of international competitiveness. Accordingly, a comparative study on the chemical composition of selected Norwegian and French apple ciders was conducted to gain knowledge on what ubiquitous chemical parameters make the Norwegian ciders different from ciders from well-established producing regions. A total of 43 ciders, 24 Norwegian and 19 French, in the category of acidic dominant ciders, were included in the study. Ethanol, individual sugars and organic acids, pH, total phenols, aroma compounds including esters, C6-alcohols, volatile phenols and terpenoids, were analysed. Norwegian ciders showed higher contents in ethanol, malic and citric acids, whereas total phenols, pH, glucose, and fructose were higher in French counterparts. Regarding the aromatic profile, no significant differences were observed for C6-alcohols. In contrast, differences were more expressed in the case of esters and volatile phenols. Norwegian ciders were characterised by higher average concentration for all the groups of esters, with the most important differences measured for higher alcohol acetates. Norwegian ciders also displayed higher contents of 4-vinylphenol and 4-vinylguaiacol while French ciders contained substantially higher levels of 4-ethylphenol and 4-ethylguaiacol. These results are in mutual correlation with the empirical observation reporting Norwegian apple ciders as more acidic, alcoholic and with lighter body but fruitier profile. Whereas French ciders are often perceived with more structure and animalistic profile.

KEMIJSKA IN SENZORIČNA ANALIZA TIPIČNIH AROMATIČNIH LASTNOSTI VIN SORTE 'MODRA FRANKINJA'
Urban Hlade, 2023, undergraduate thesis

Abstract: 'Modra frankinja' (Vitis vinifera L.) je tradicionalna slovenska sorta grozdja, a kljub temu Slovenci o njej nismo dovolj seznanjeni. Tudi ko gledamo širši vinski svet, opazimo, da o tej sorti in njenih značilnostih vemo zelo malo. Po naših podatkih aromatične tipičnosti vin sorte 'Modra frankinja' še niso bile raziskane. Diplomsko delo je prva tovrstna raziskava te sorte. V delu smo želeli raziskati aromatične lastnosti vin te sorte s pomočjo neformalne senzorične analize. Na ta način smo povzeli katere senzorične note so na splošno izrazite pri obravnavani sorti vina. V nadaljevanju smo s kemijsko analizo aromatičnih spojin vzorcev vina to še kemijsko ovrednotili. Pri kemijski analizi smo se osredotočili na štiri skupine spojin, ki po našem mnenju krojijo tipičnost arom vin sorte 'Modra frankinja'. To so: monoterpeni, estri, norizoprenoidi in C6-alkoholi. Rezultati kažejo, da so prav predstavniki skupine terpenov tisti, ki se pojavljajo v največjih koncentracijah v obravnavanih vinih in pomembno krojijo aromatični profil vin 'Modra frankinja'. C13-norizoprenoidi so bili prisotni v večjih koncentracijah pri vzorcih sortnega vina 'Modra frankinja', kot pri vinih 'Modri pinot' ali vinih bordojskih sort. A še vedno vsebnosti C13-norizoprenoidi ostajajo precej manjše od zaznavnih senzoričnih pragov teh spojin.
