Astringency in a Japanese persimmon (<I>Diospyros kaki</I> Thunb.) fruit is mainly caused by soluble tannin. A computer image analysis method was tried for easier, quicker and more accurate measurement of soluble tannin content in persimmon fruit. Perpendicular sections of fruits of Japanese persimmon cvs. Hiratanenashi and Monpei were printed on filter papers dipped in 3% FeCl<SUB>3</SUB> solution. The mirror images on the filter papers were digitized by a gray scale image scanner. These digital images were thresholded, and the percentages of black pixels in transverse images were counted as an index of soluble tannin content, named tannin index. The tannin index was compared with the soluble tannin content measured by the Folin-Denis method. The tannin index correlated highly with the soluble tannin content in both cultivars, and this indicates the image analysis method is capable of measuring soluble tannin in persimmon fruit.
