To provide a frozen food capable of reducing heating time till thawing, the highest heating temperature and uneven heating and preventing deterioration of the food and unevenness in taste, a packaged frozen food including the frozen food； a manufacturing method of the food and a frozen food which can prevent aging of starch and can control viscosity of the food as set by pregelatinizing a starch content at first by heating and thawing at the time of eating.SOLUTION: A food generating method comprises: at least a step of mixing oil and starch before pregelatinization and generating a plurality of first frozen compositions； a step of at least mixing a low heat-resistant material and a water content and generating a plurality of second frozen compositions； a step of mixing the plurality of first frozen compositions and the plurality of second frozen compositions and generating a frozen food including them； and a step of heating the generated frozen food and pregelatinizing the starch of the first frozen compositions by the water content of the second frozen compositions. The frozen food is obtained by the food generating method.SELECTED DRAWING: Figure 1【課題】解凍までの加熱時間、最高加熱温度及び加熱むらを低減し、食品の品質劣化及び味のばらつきを防ぐことが可能な凍結食品、この凍結食品を含む容器入り冷凍食品、及び食品の製造方法、及び、喫食時の加熱解凍によって初めて澱粉成分をα化させることで、澱粉の老化を防ぐことに加え、食品の粘性を設定通りに制御可能な凍結食品等の提供。【解決手段】少なくとも、油脂及びα化前の澱粉を混合し、複数の第一の凍結組成物を生成するステップと、少なくとも、低耐熱性素材及び水分を混合し、複数の第二の凍結組成物を生成するステップと、前記複数の第一の凍結組成物と、前記複数の第二の凍結組成物とを混ぜ合わせ、これらを含む凍結食品を生成するステップと、生成された前記凍結食品を加熱し、前記第二の凍結組成物の水分によって、前記第一の凍結組成物の前記澱粉をα化させるステップと、を含む、食品生成方法。該食品生成方法により得られる凍結食品。【選択図】図１
