    Abstract: A method for producing a roasted grain extract with which a sufficient concentration can be obtained is realized. This production method includes a roasting step (S10) of roasting a grain (unpolished rice 1) while the grain remains in a granular form, an impregnating step (S20) of impregnating the roasted grain with an impregnation liquid LQ1 (water) so that an inside 1b of the grain is swollen and the grain is cracked open, and an extracting step (S30) of extracting a roasted component that is present in the inside of the grain by bringing a solvent LQ2 (water) into contact with the inside of the grain that has been cracked open. In the roasting step, the grain is heated in a state in which the entire inside thereof has absorbed moisture and a carbonized coating 1b is formed on the surface of the grain, after which the inside of the grain is carbonized.
