Description

ELECTRONIC DEVICE AND METHOD OF DETERMINATING TYPE AND STATUS OF FOOD STORED THEREIN The various embodiments disclosed in this document relate to an electronic device and a method for determining the type and condition of food stored therein. As a general refrigeration system, a refrigerator is a device that cools the designated refrigerator and freezer compartments formed inside using cold air to keep food fresh for a long time. Food stored in a refrigerator can maintain its freshness for a certain period under low temperatures, but over time, it eventually ripens or spoils. Users can determine the degree of ripening or spoilage of food stored in the refrigerator through cognitive actions such as remembering the time of initial storage, visual observation, or smell. However, such methods suffer from low accuracy in determining whether food is ripe or spoiled, and situations where users forget the storage date and miss the deadline for consuming the food while it is fresh occur frequently. Furthermore, according to one embodiment, users may be exposed to the risk of contracting diseases such as food poisoning by consuming spoiled food. Accordingly, measures are being researched to ensure safe consumption by predicting the ripening and spoilage status of food. For example, methods are being studied to predict the type and condition of food by detecting gases generated from the food. When food spoils, various types of gases, such as ammonia, hydrogen sulfide, and methane, may be produced.
