Aromatične snovi v staranih penečih vinih : diplomska naloga = Aroma compounds in aged sparkling wines : graduation thesisCegnar, SašaNamen diplomske naloge je dolořiti koncentracije viǴjih alkoholov in laktonov,kot skupino aromatiřnih snovi, v trinajstih staranih peneřih vinih pridelanih po klasiřni metodi in ugotoviti morebitno ... korelacijo med koncentracijo teh aromatiřnih snovi in starostjo peneřega vina. Peneře vino smo destilirali in s plinsko kromatografijo dolořili koncentracije acetaldehida, etil acetata, metanola, n-propanola, izobutanola, izoamilnega alkohola in 2-fenil etanola. Za dolořanje ?-oktalaktona smo peneře vino ekstrahirali s solventno eksrakcijo in ga kvalitativno in kvantitativno dolořili s plinsko kromatografijo in masno spektroskopijo. V trinajstih vzorcih peneřega vina znaǴajo koncentracije: acetaldehida od 34,55 do 170,93 mg/100 g etanola, etil acetata od 20,25 do 70,30 mg/100 g etanola, metanola od42,88 do 65,46 mg/100 g etanola, n-propanola od 30,82 do 51,80 mg/100 g etanola, izobutanola od 48,49 do 104,07 mg/100 g etanola, izoamil alkohola od 131,26 do 224,37 mg/100 g etanola, 2-fenil etanola od 20,21 do 49,83 mg/100 g etanola in ?-oktalaktona od 14,98 do 57,51 Ùg/l. Statistiřno znařilnih korelacij med starostjo peneřega vina in koncentracijo viǴjih alkoholov ni. Koncentracije ?-oktalaktona in acetaldehida statistiřno znařilno naraǴřajo s starostjo peneřega vina.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [BF, Oddelek za živilstvo] : [S.
