PROBLEM TO BE SOLVED: To provide a manufacturing method of shape retention type softening foods which has no need for a specific device, is simple and low cost and includes a process for effectively introducing an enzyme to massive food materials or food materials retaining an original shape.SOLUTION: There is provided a method for manufacturing shape retention type softening foods including introducing an enzyme to massive food materials or food materials retaining an original shape and conducting an enzyme reaction, in which the enzyme is introduced into the food materials by not a pressure treatment, but a diffusion action during thawing, while conducting a slow thawing treatment on a surface of the food materials, which is slow thawed at a state without contact with the enzyme, at a state with contact with the enzyme.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】特別な装置を必要とせず、簡易かつ安価な方法で、塊状の食材又は元の形状を保持する食材に酵素を効率的に導入する工程を含む形状保持型軟化食品の製造方法の提供。【解決手段】塊状の食材又は元の形状を保持する食材に酵素を導入し、酵素反応を行って、形状保持型軟化食品を製造する方法であって、酵素に接触させない状態で緩慢凍結させた食材の表面に、酵素を接触させた状態で緩慢解凍処理を行いながら、圧力処理ではなく融解時の拡散作用によって食材内に酵素を導入することを特徴とする。【選択図】図１
