Abstract: The present invention relates to a process of preparing a caramel color based food dye having the same or greater color intensity compared to that of a conventional caramel dye, and a caramel color based food dye using the process. The process uses Maillard reaction, not caramel reaction, to prepare a caramel color based food dye. It is possible to prepare a caramel color based food dye that does not generate harmful substances such as 4-MEI and has a similar color intensity and a color pattern as the conventionally used type-III caramel dye. Moreover, it is possible to avoid a harmful problem caused by the conventional type III caramel dye since the food dye of the present invention can be replaced with the conventional type III caramel dyes in the same amount.

Abstract: The invention relates to a high-dielectric constant metal/ceramic/polymer composite material and a method for producing an embedded capacitor. As ceramic particles having a relatively small size are bound to the surface of metal particles having a relatively large size by mixing, the occurrence of percolation can be prevented without coating the metal particles, and at the same time, the capacitance of an embedded capacitor can be increased. In addition, a process for coating the surface of the metal particles can be omitted, thus contributing to the simplification of the overall preparation procedure.
