Zusammenfassung:	An overcooled meat fresh-preservation control method, a controller and a refrigerator are provided. The control method comprises: S1 (101), acquiring a current temperature of meat food in a compartment of a refrigerator in real time; S2 (102), judging whether the current temperature of the meat food is greater than or equal to a first temperature threshold t0, and if yes, performing step S3 (103); S3 (103), controlling the compartment to perform a cooling operation; S4 (104), judging whether the meat food has been cooled down to a phase transformation point temperature t1 during the cooling operation, and if yes, performing step S5 (105), the phase transformation point temperature t1 being the temperature of a critical point at which the phase transformation of the meat food occurs; S5 (105), starting timing once the temperature has been cooled down to the phase transformation point temperature t1, and performing step S6 (106) after the timing reaches a first preset time period; and S6 (106), controlling the compartment to perform a low-temperature stable operation according to a third target temperature T3, the third target temperature T3 being a freezing point temperature of the meat food. The overcooled meat fresh-preservation control method provided by the present disclosure may prolong the fresh-preservation period as much as possible while ensuring that the meat food is not frozen.
