Method for detecting freshness of refrigerator food and refrigerator

Abstract

The invention discloses a method for detecting freshness of food in a refrigerator and the refrigerator. The refrigerator is provided with a spectrograph and a control system which are in communication connection, the refrigerator is in communication connection with a cloud server, the control system comprises a food freshness analysis unit and a display unit which are in communication connection, and the cloud server comprises a spectrum data processing unit and a spectrum analysis engine which are in communication connection. The spectrograph is adopted as an odor detection device, and multi-component gases in the refrigerator are detected simultaneously online by the aid of a remote real-time analysis system of a cloud. With the adoption of the method, various gas components in the refrigerator can be recognized accurately, multiple gases can be recognized and distinguished simultaneously, so that the accuracy problem about detection of food decay gases is solved, and which kind of food produces decay gases can be distinguished according to the gas components and concentration proportion.

Description

technical field [0001] The invention relates to the field of refrigerator food detection, in particular to a method for detecting the freshness of refrigerator food and a refrigerator. Background technique [0002] Refrigerator has become an essential household appliance for storing food in the family, but after people put food into the refrigerator, they often forget to eat it in time, so that the food deteriorates. This not only leads to wastage of food, but also makes the refrigerator smell worse and even cause a large number of bacteria to grow. [0003] When food goes bad, it will emit various odors, and different types of food emit different odor components. For example, the main odor components emitted by fruits and vegetables are ethanol, hydrogen sulfide, and hexanal; the main odor components emitted by meat are hydrogen sulfide, mercaptan, and cadaverine; the main odor components emitted by fish are trimethylamine and hexanal. [0004] For this reason, a patent p...
