[PROBLEMS] To produce a large number of semi-boiled rice-like ingots that are lightly boiled and boiled with rice, just by mixing with an aqueous medium without heating at home. The lump can be made into a molded food that is bound and held in any shape such as a rice ball by a light press such as an infant holding it with one hand. Provided is a powder that can have a light texture such as half-boiled cooked rice. A non-heated hydroforming product for producing a cooked rice-like food that can be eaten as it is by adding an aqueous medium in a weight ratio of 0.5 to 1.4 to powder 1 and hydrated without heating. The above object is achieved by a non-heated hydroforming powder comprising 30-60% by weight of pregelatinized cereal powder and a saccharide sweetener in the total weight of the powder. [Selection figure] None【課題】家庭において非加熱で水性媒体と混合して短時間混合するだけで、ご飯を軽く杵で搗いたような半搗きの米飯状の不定形塊状物が多数生成でき、かつ、これをちぎったり、丸めたりすることができ、またこの塊状物同士が、幼児が片手で握るなどの軽い押圧によっておにぎり状等の任意の形状に結着保形した成形食品とすることができ、食感も半搗き米飯のような軽い食感とすることができる粉末を提供する。【解決手段】粉末1に対して重量比で水性媒体0.5~1.4を添加し、非加熱での加水混合によってそのまま喫食可能な米飯状成形食品を製造するための非加熱加水成形用粉末であって、該粉末の全体重量中にα化穀類粉末30~60重量%と糖質甘味料とを含有してなる非加熱加水成形用粉末によって上記目的を達成する。【選択図】なし
