PROBLEM TO BE SOLVED: To provide efficiently producible crystal sugar having unrefined brown sugar flavor, ensuring the pigment component and flavor component of unrefined brown sugar to be efficiently kept in the crystal form of crystal sugar with a large granular size.;SOLUTION: The unrefined-brown-sugar-processed crystal sugar is provided, being produced by the following process: a seed crystal is immersed in an unrefined-brown-sugar-dissolved liquid to effect crystal growth for a predetermined period of time under adjustment to 45-55°C, in which in an intermediate period of the predetermined period of time, there is provided a crystal growth period adjusted to a temperature 1-5°C higher than that before or after the intermediate period, and during the crystal growth period, a sucrose crystal with cracks is formed to include or deposit the coloring component, mineral component, or flavor component of unrefined brown sugar component in or on the sucrose crystal.;COPYRIGHT: (C)2013,JPO&INPIT
