Influence of glycosidases addition on selected monoterpenes contents in musts and white wines from two grape varieties grown in Poland

摘要

Background. Amount of monoterpene alcohol and their glycoside precursors in grapes is determined by the type of grapes, and the availability of specific hydrolytic enzymes during the manufacturing process. Addition of these enzymes, hydrolysing β-glycosidic bond, to the grape can be used to increase the potential of aromatic raw material, releasing odoriferous aglycons from non-volatile glycosides and in consequence to enhance the flavour of white wines. In this study complex enzyme preparations AR2000 and Rapidase X-Press were used as a supplement to the musts.
