A method for producing a food material made of a bean peel as a raw material includes dehydrating a peel separated from boiled adzuki beans into a predetermined water content, primary milling the peel obtained by the dehydration step into a desired particle size water addition for adjusting, by water addition, the water content of the peel powder obtained by the primary milling step to a predetermined level, and a secondary milling of the peel powder obtained by the water addition adjustment step into fine particles such that the palisade tissues of the peel powder are separated in a fine, almost rod-like (elongated) form.
