SOLID FOOD AND SOLID MILK

Provided are a solid food and a solid milk which have a suitable adhesive force and strength adequate to resist breakage during handling. The solid food is a solid food having a solid form obtained by compression molding a food powder, the solid food containing monohydrate crystals and anhydride crystals, in which an increase ratio β/(α+β) of a crystallization rate of an increase β (% by weight) in crystallization rate that is a difference of a ratio of the anhydride crystals with respect to a total weight on a surface of the solid food relative to a ratio of the anhydride crystals in an inner part of the solid food to the sum (α+β) of an increase α (% by weight) in crystallization rate that is a difference of a ratio of the monohydrate crystals with respect to the total weight on the surface of the solid food relative to a ratio of the monohydrate crystals in the inner part of the solid food and the increase β (% by weight) in crystallization rate is 0.15 or more, and a peel and shear stress on a flat face is 0.020 N/mm2 or less.
