[Use of enzyme preparations in wine production (author's transl)].
The Author after having examined the present acquirements of the native enzymes of the grapes, summarizes the enologic uses of the enzyme preparations at various degrees of purity with the point of view of the influence on the organoleptic (color, aromatic composition) ad rheologic (yield, filtrability) characteristics of the musts and wines besides some microbiological implications. Subsequently the Author exposes the original results extrapolated from the pilot and industrial trials on the use of different hydrolases (pectinase, cellulase, hemicellulase, acid protease, xylanase) on the wine-making processes (traditional red wine-making, heating red-wine-making, white wine-making). From the comparison of the last data with those of the reference are drawed conclusive considerations on some aspects of the subject.
