a refrigerator body, including a storage compartment;

a door disposed at an opening of the storage compartment;

a display arranged on the door;

a voice collector, configured for receiving a voice command input from a user, wherein the voice command is associated with operations about food in the storage compartment; and

a processor, in connection with the display and the voice collector, wherein the processor is configured for causing the refrigerator to perform:

presenting a first food editing interface on the display, wherein the first food editing interface comprises an input item available for receiving an input from the user, and the input item is for indicating a food quantity and a food shelf life, and the input item comprises a value and a measuring unit;

during presentation of the first food editing interface, receiving a first voice command input from the user via the voice collector;

obtaining a first operation type and first operation data for operating a food quantity by parsing the first voice command, wherein the first operation data comprises a first operation value and a first measuring unit;

in response to the first operation data being inconsistent with a pre-stored value and/or a pre-stored measuring unit, determining whether the first measuring unit is a preset measuring unit and whether the first operation value falls within a preset operation range for the first measuring unit;

in response to the first measuring unit being the preset measuring unit and the first operation value falling within the preset operation range, determining whether the first measuring unit matches the pre-stored measuring unit in category;

in response to the first measuring unit matching the pre-stored measuring unit in category and the first operation type being an operation for inputting a food quantity, determining the first operation value as a target display value;

in response to the first measuring unit matching the pre-stored measuring unit in category and the first operation type being an operation for modifying a pre-stored food quantity, determining a target display value according to the first operation value and the pre-stored food quantity; and

according to the determined target display value and the first measuring unit, updating the first food editing interface to obtain a second food editing interface.
