The ground persimmon puree was treated with two kinds of commercial polysaccharide hydrolyzing enzymes (Viscozyme and Celluclast) in order to study their effects on the extraction yield, viscosity, color, titratable acidity and sugars. Hydrolysis with Viscozyme which has enzymatic activity of arabinase, cellulase, xylanase, hemicellulase and ${\beta}-glucanase$ significantly increased the extraction yield, L-value and reducing sugar and decreased in viscosity by treatment for 10 min at $50^{\circ}C$. The extraction yield of the juice was increased from 42.7% to 80% by Viscozyme while the Celluclast to 73.3%. On the other hand, the sensory properties of persimmon-like flavor, scarlet and orange color were greatly improved for the juice hydrolyzed with Viscozyme for 60 min.
