(57) [Summary] [Purpose] To provide seamless capsules containing oily substances that are easily oxidized. In a seamless capsule comprising a content, a coating film for coating the content, and a protective layer interposed between the content and the coating, the content is an oily substance which is easily oxidized, A seamless capsule characterized in that the layer is a substance having low oxygen permeability and low moisture permeability, wherein the seamless capsule is composed of at least three layers arranged in concentric circles having successively increasing radii. From the outermost nozzle of the nozzle, the coating liquid for seamless capsules, and the innermost nozzle from the oxidizable substance liquid, It is manufactured by simultaneously extruding a substance liquid having low oxygen permeability and low moisture permeability into a cooling medium from at least one intermediate nozzle located between two nozzles. |
