Abstract: Provided is a method which is capable of three-dimensionally forming a food into a desired shape such as a complicated shape or a hollow shape, using a starch powder as a raw material. The method for three-dimensionally forming a food using a starch powder as a raw material comprises the steps of: mixing a starch powder and water together to provide a mixture of the starch powder and the water; irradiating a part of the mixture with laser light to cause starch particles of the starch powder to swell due to the water to form swollen starch particles, followed by causing the swollen starch particles to gelatinize to form gelatinized starch particles, and causing the gelatinized starch particles to gelate, thereby obtaining gelated starch: and extracting the gelated starch from the mixture, wherein the step of irradiating includes irradiating the mixture with the laser light, according to a pattern predetermined based on a three-dimensional shape of a food.
