Laser Cooking is research that supports the development of new flavors and cooking techniques through localized heating methods that combine laser cutters and image processing technology. Using machine-controlled high-power lasers to perform precise heating according to the composition and shape of ingredients, we can cook only specific parts of ingredients, apply complex decorations to ingredient surfaces, and provide information to assist in cooking.
The photo above shows bacon where only the fat portions have been laser-heated and cooked. This creates new flavors where unheated and heated portions coexist, while also providing a method to remove fat without cooking the lean portions. Such cooking can be performed automatically using image processing technology.
In recent years, the cost of computer-controlled automatic manufacturing machines has decreased, making it possible to easily perform complex manufacturing work at home. We aim to introduce the use of such manufacturing machines in part of the cooking process to enable fine cooking and labor-saving that would be difficult for amateurs to achieve at home, and to support the development of completely new cuisine that has never existed before.
Laser Cooking also introduces new methods for recipe notation. The example above shows ingredient placement diagrams engraved on nori seaweed surfaces using a laser. When a cross-sectional design of a sushi roll is input into a computer, it automatically calculates the required amount and placement of ingredients and engraves them on the nori. By placing ingredients according to the diagram and rolling, you can create sushi rolls with your desired design. The placement diagram is engraved by charring the nori surface, requiring no additional components.
Using similar methods, it is also possible to engrave barcode information for computer reading. Integration with smartphone apps is also possible.
Furthermore, by layering, it enables the creation of edible three-dimensional sculptures.
