PROBLEM TO BE SOLVED: To provide a method for extracting pigments, a method for manufacturing colored salt, and a pigment, in which pigments and minerals can be extracted from various plants.SOLUTION: In a fermentation process 11, plant material 2 including at least one of marine plants, fruits, flowers, vegetables, bamboos, trees, and plants is added to water 1 to be sealed for lactic fermentation. At this time, the plant material 2 may be added for fermentation to the water 1 to which at least one of salts, sugars, acids, and alkalis is added. In a concentration process 12, fermentation gas is removed from fermented matter, and heat concentration or dehumidification concentration is performed to extract pigments. In a coloring process 13, extracted pigments are mixed with salt 3 to be dried to provide the colored salt 4.COPYRIGHT: (C)2012,JPO&INPIT【課題】様々な植物から色素やミネラル分を抽出することができる色素抽出方法、着色塩の製造方法および色素を提供する。【解決手段】発酵工程11で、水1に、海草、果物、花、野菜、竹類または草木類のうち少なくとも1つから成る植物系原料2を加え、密閉して乳酸発酵させる。このとき、水1に塩分、糖分、酸およびアルカリのうち少なくとも1つを加えたものに、植物系原料2を加えて発酵させてもよい。濃縮工程12で、その発酵物から発酵ガスを取り除いた後、加熱濃縮または除湿濃縮を行って色素を抽出する。着色工程13で、抽出された色素を塩3と混合し、乾燥させて着色塩4を得る。【選択図】図1
