- 摘要：
PROBLEM TO BE SOLVED: To provide a method for efficiently obtaining an anthocyanin pigment, which is useful for food industries and mainly formed of nasunin, from a preliminary pickling liquid produced in a process for manufacturing pickles of an eggplant.
SOLUTION: The preliminary pickling liquid 8, which is produced in a processing process of pickles of an eggplant containing an anthocyanin pigment principally consisting of nasunin and contains sodium chloride and aluminum alum, is used as a material liquid. An anthocyanin pigment-containing liquid is obtained when the material liquid is passed through a porous styrene-divinylbenzene resin 4 to remove mineral constituents and the like including the sodium chloride and the aluminum alum, and then, an acetic acid liquid is passed through the porous resin 4 adsorbing the anthocyanin pigment principally consisting of nasunin to separate the anthocyanin pigment principally consisting of nasunin from the porous resin 4.
