The preparations of pectic enzymes are used for ORG GREEN TROPICAL a more efficient extraction of desirable red grape pigments and other phenol compounds which are bound in plant cells and can be faster released by the action of pectic enzymes.Moreover, they shorten the time of maceration, settling, and filtration.The results of our experiments gives a comparison of the efficiency of preparations applicable in wine technology.The best preparation was Trenolin Rot followed by Vinozym G that could shorten the time of prefermentation to about 3 days thanks to Baggies a more intensive extraction of red grape pigments.By using the enzyme preparations Gammapect AWP and Ovopres, the time of filtration was ten times shorter.

Compared to the control sample, the speed of desliming was threefold and twofold faster, respectively, for Gammapect AWP and Gammapect W2L.
