<;P>;PROBLEM TO BE SOLVED: To provide a method for producing a plum liquor, in which a maturing period in a process for producing the plum liquor can be shortened, as much as possible, and by which the mild plum liquor containing ingredients useful for health as much as possible and having a high commercial value can be produced. <;P>;SOLUTION: This method for producing the plum liquor comprises pickling immature plum fruits in an ethyl alcohol-containing solution prepared by adding a sweet saccharide to shochu (white distilled liquor), or the like. The plum fruits are preferably plum fruits obtained by making plum fruits to contain a pectinase such as protopectinase originated from Trichosporon penicillatum to regenerate the fleshes of the fruits. Hence, the mild plum liquor containing polyphenol ingredients of anti-oxidizing substances useful for health in large amounts and having a high commercial value can be produced, in a short period. <;P>;COPYRIGHT: (C)2009,JPO&INPIT
