Abstract:
A method of making a drawing on a chocolate by causing a pulsed laser to irradiate the surface of a solid chocolate under limited operation conditions, and a chocolate manufactured by said method are provided. The irradiation energy per pulse and the irradiation energy per sweeping unit line length of the pulsed laser are limited to a certain range. The trace of the laser irradiation remains circular or arc-shaped on the surface of the chocolate manufactured under the above conditions. Further, the method makes a drawing on the surface of the chocolate, using the phenomenon that chocolate changes color when being irradiated by a pulsed laser under the above operation conditions.
