Abstract

Slobodne aminokiseline u moštu su važan izvor dušika za kvasce tijekom alkoholne fermentacije. Cilj ovog istraživanja bio je odrediti aminokiselinski profil mošteva devet sorata vinove loze (šest bijelih i tri crne). Sorte vinove loze zasađene su u ujednačenim uvjetima tla i klime vinogorja Bilogora (Regija Kontinentalne Hrvatske, podregija Prigorje-bilogora) te su imale iste agrotehničke uvjete uzgoja. Pokus je postavljen 2015. godine. Rezultati su pokazali signifikantan utjecaj sorte na aminokiselinski sastav u moštevima bijelih i crnih sorti. Najzastupljenija aminokiselina u moštevima devet sorata vinove loze bila je arginin. Najveća koncentracija arginina kod bijelih sorata bila je u moštu Chardonnay (470,18 mg/l), a kod crnih sorata u moštu Lovrijenca (280,65 mg/l). Statistički značajne razlike nađene su između koncentracije ukupnih aminokiselina bijelih i crnih sorata. Najveća koncentracija ukupnih aminokiselina kod bijelih sorata bila je u moštu sorte Manzoni (1639,51 mg/l), a kod crnih sorata u moštu sorte Pinot crni (1173,12 mg/l)

Abstract

Free amino acids in grape juice are important as nitrogen source for yeast strains during alcoholic fermentation. The aim of this research was to determine amino acid profiles in musts from nine grapevine cultivars (six white and three red). The cultivars were located in a homogeneous soil and climatic zone of Bilogora growing hill (West continental region, Prigorje–bilogora subregion), grown on the same training system. The experiment was conducted in vintage 2015. The results showed significant influence of grape cultivar on the amino acids composition in musts of white and red grape cultivars. Arginine was dominant in most analyzed varieties of amino acids. The highest concentration of arginine in white cultivars was measured in Chardonnay must (470.18 mg/L) and in red cultivar must from Saint Laurent (280.65 mg/L). Statistically significant difference was also found in the total amino acid composition of white and red cultivars. The highest concentration of total amino acids in white cultivars was determined in Manzoni juice (1639.51 mg/L) and among the red cultivars in Pinot noir juice (1173.12 mg/L).
