In this thesis were analysed polyphenoloxidase, pectin methylesterase, β-glucosidase and esterases of two autochthonous grapes Moscato bianco and Prosecco. The aim was to control the positive and negative effects of these enzymatic activities during storage and trasformation of grape into wine and distillate and establishing the role of each activity in function of plant or microbial origin. To characterize the enzymes were employed different analytical techniques as spectrofotometry, gascromatography, electrophoresis and MALDI-TOF. The results given the opportunity to realize a patent for the control of methanol concentration in grape pomaces.

Abstract

In this thesis were analysed polyphenoloxidase, pectin methylesterase, β-glucosidase and esterases of two autochthonous grapes Moscato bianco and Prosecco. The aim was to control the positive and negative effects of these enzymatic activities during storage and trasformation of grape into wine and distillate and establishing the role of each activity in function of plant or microbial origin. To characterize the enzymes were employed different analytical techniques as spectrofotometry, gascromatography, electrophoresis and MALDI-TOF. The results given the opportunity to realize a patent for the control of methanol concentration in grape pomaces.
