[0737] I Microcapsules
[0738] In the following, different examples of the preparation of microcapsules according to the invention are described in order to illustrate the invention.
example 1
[0739] Example 1 : Preparation of microcapsules with inner brown coating and outer white coating
[0740] Mannitol (spray-dried mannitol: Pearitol 100SD) was used as the core.
[0741] Add 120.0g of ceramide (ceramide PC 104) and 120.0g of hydrogenated lecithin (lipid S100-3) to a mixed solution of 1600.0g of dichloromethane and 1600.0g of ethanol, and dissolve completely at 40°C . 1260.0 g of iron oxide yellow, 252.0 g of iron oxide red, and 45.36 g of iron oxide black were added to the resulting mixture, and sufficiently dispersed using a homogenizer to prepare an internal color coating solution.
[0742] The mannitol of 347.70g is introduced into fluidized bed coating system (Glatt GPOG 1, bottom spray), as seed, is subjected to then coating internal color coating solution with the feed rate of 500ml / h, to obtain the coating with Granules of the mannitol core of the inner color layer.
[0743] Thereafter, 36.0 g of ceramide and 36.0 g of hydrogenated lecithin were adde...
example 2
[0746] Example 2 : Preparation of microcapsules with inner yellow coating and outer white coating
[0747] Microcapsules were prepared in the same manner as in Example 1, except that 1557.36 g of iron oxide yellow was used instead of the mixed colorant composed of iron oxide yellow, iron oxide red and iron oxide black as the inner color in preparing the inner color coating solution.
