Abstract

Here we describe the capsule technologies of Morishita Jintan (MJ), Japan-based company, which provides services to customers through healthcare business and contract manufacturing of seamless capsules. Seamless capsule is a type of soft gel capsules and can be obtained by MJ's original dropping method. The history of MJ's seamless capsule technology is back to the early ‘70s. Since then, MJ has developed various types of seamless capsules with multilayered structure;2-layered capsules for oil-based flavors, 3-layered capsule for aqueous solution and hydrophilic solution of pharmaceutical active ingredients, 3-layered capsules with acid-resistance shell for protecting probiotic cells, and 4-layered capsules (capsule-in-capsule). MJ has applied the capsule technology to own products and contract manufacturing of seamless capsules for worldwide customers. Nowadays the application of MJ's capsule technology is not limited to the foods, cosmetics, and pharmaceuticals, but rather extending to wide range of industry such as daily items, housing products, logistics, machinery, and electronics. In order to respond to various customers' requests, MJ continues updating the core capsule technology for the conventional applications and developing novel capsule technologies for the new applications;seamless capsules with non-edible shells and microcapsules.
