摘要： The present invention relates to a method for the production of a lutein-fatty acid ester concentrate of high purity by dissolving marigold oleoresin in a ketone solvent such as acetone, cooling the solution, and removing wherefrom a ketone solvent-insoluble component to uniform the quality of oleoresin, followed by dissolving the acetone-soluble portion obtained as above in butanol, cooling the solution, removing a butanol-soluble impurity after adding or without adding one or more members selected from the group consisting of water, methanol, ethanol and a mixture thereof, and washing the resulting butanol-insoluble with ethanol.

摘要： Provided is a method for producing a gardenia blue pigment resistant to discoloration which may occur in colored sugar-coated food or pharmaceutical products. The method for producing such a gardenia blue pigment comprises performing membrane separation using a membrane (for example, an ultrafiltration membrane) with a molecular weight cut-off of 3000 Da or larger for removal of low-molecular compounds from a solution resulting from β-glucosidase treatment of an iridoid glycoside (for example, geniposide etc.) in the presence of a protein hydrolysate (for example, a casein protein hydrolysate), the iridoid glycoside being obtainable by extraction from fruits of Gardenia jasminoides (Rubiaceae). Also provided is a sugar-coated food or pharmaceutical product (for example, a sugar-coated tablet, a sugar-coated chewing gum, etc.) having a sugar-coating layer colored with the gardenia blue pigment obtainable by the above-described method.
摘要翻译：本发明提供一种可以在着色的糖衣食品或药品中产生耐褪色的栀子蓝色素的方法。生产这种栀子蓝颜料的方法包括使用分子量截留为3000Da或更大的膜（例如超滤膜）进行膜分离，以从由β-环糊精得到的溶液中除去低分子化合物，在蛋白质水解产物（例如酪蛋白蛋白水解产物）存在下，环烯醚甙（例如栀子苷等）的葡糖苷酶处理可以通过从栀子栀子（茜草科）的果实中提取而获得的环烯醚萜苷。还提供了具有通过上述方法获得的栀子蓝颜料着色的糖衣层的糖衣食品或药物产品（例如，糖衣片，糖衣口香糖等）。
