Abstract

The invention provides a method for detecting freshness of food in a storage chamber of a refrigerator. The method includes the steps that the odor intensity of odor in the storage chamber of the refrigerator is detected according to a preset time interval, and the odor intensity is used for representing the influence degree of the odor in the storage chamber on the olfactory sensation; the change rate of the odor intensity is calculated; whether the change rate is larger than or equal to a first preset value is judged; and when the change rate is larger than or equal to the first preset value, a signal indicating that food in the storage chamber rots is output. The freshness of food can be judged according to the change rate of the odor intensity used for representing the influence degree of the odor in the storage chamber on the olfactory sensation, a user can accurately and timely obtain the freshness of food in the storage chamber of the refrigerator and timely obtain food rotting information, and therefore the user can timely clean the refrigerator and effectively monitor the freshness of food in the refrigerator.
