To freeze food in a state of being divided into small portions, by equipment having an easier structure.SOLUTION: A freezing method includes: a first cooling step of generating a first food chunk by freezing food which can be divided into small portions by a human hand without using a tool at a temperature higher than a freezing temperature； a second cooling step of bringing the first food chunk into a state of being divided into small portions, while it is in a frozen state, by a human hand without using a tool； a division step of dividing the first food chunk which is brought into a state of being divided into small portions, while it is in a frozen state, by a human hand without using a tool in the second cooling step into a plurality of second food chunks； and a third cooling step of freezing the plurality of second food chunks.SELECTED DRAWING: Figure 5【課題】より簡易な構造の機器によって、小分け可能な状態の食品を冷凍保存する。【解決手段】 本発明に係る冷凍保存方法は、凍結温度よりも高い温度において人間の手で道具を使わずに小分け可能な食品を凍結させて第１食品塊を生成する第１冷却工程と、第１食品塊を、凍結された状態のまま人間の手で道具を使わずに小分け可能な状態にする第２冷却工程と、第２冷却工程によって凍結された状態のまま人間の手で小分け可能な状態にされた第１食品塊を複数の第２食品塊に小分けする分割工程と、複数の第２食品塊を冷凍保存する第３冷却工程と、を備える。【選択図】図５
