<P>PROBLEM TO BE SOLVED: To solve the problems that which kind of detergents must be used, which means for efficiently reducing astringency must be adopted, and how a persimmon skin must be processed to reduce the astringency of the texture of the persimmon skin as hard and dense tissue and poorness of water penetration properties because the means for utilizing the persimmon skin conventionally not utilized by any method and discarded, as a food indispensably requires cleaning of remaining agrochemicals and dust, and the detergent indispensably requires being good for the body and harmless. <P>SOLUTION: The cleaning of the remaining agrochemicals and dust attached to the persimmon skin formed by peeling a persimmon is carried out by using a solution of potassium carbonate or an alkali ion water having both of the cleaning activities and activities for reducing and insolubilizing persimmon tannin to reduce the astringency. Cells are denatured into a ripe persimmon state by heating or freezing after dehydration to achieve the insolubilization of the persimmon tannin again by using a reducing power of acetaldehyde possessed by the persimmon skin itself, and the resultant persimmon skin is dried. The dried persimmon skin is roasted to expand the tissues in the persimmon skin in an extremely dried state. When the persimmon skin is cooled by stopping the heating, the tissues shrink, and can be crushed by a small external pressure. As a result, the water penetration properties and the flavor are provided, and the objective persimmon skin food having the good texture is provided. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
