In step S42, the microcomputer 80 reads the food storage information stored in the storage means 30, and determines whether there is food storage information corresponding to the input name or identification information of the food. If there is food storage information, go to step S44, otherwise go to step S43.

In step S43, the microcomputer 80 reads a guide message relating to the absence of food storage information stored in the storage means 30 and displays it on the liquid crystal display 42.

In step S44, the microcomputer 80 transmits an operation command to the light generating means 60 according to the optical characteristics included in the food storage information corresponding to the food, and the light generating means 60 receives the received operation command. And generates and emits light, such that the food is exposed to this light.

In the graph of FIG. 6, the horizontal axis relates to temperature, and the vertical axis relates to the percent retention of vitamin C stored in strawberries. Here, C is a case where the strawberry is stored by a conventional storage method (temperature control) that is not exposed to light, LED is a strawberry is exposed to the light of the color according to the food storage information, the temperature is controlled by a food storage method It is archived. In addition, the vertical length of each rectangle means the deviation in an experiment.

As shown, when the storage temperature of the storage unit 6 is the same, the center point of the vitamin C preservation rate (%) rectangle of C is the center point of the vitamin C preservation rate (%) rectangle of the LED (center of deviation). Even lower, even if the storage temperature of the storage unit 6 is changed to improve the vitamin C preservation rate (%) of C, the vitamin C preservation rate (%) of the LED appears to be much improved. In addition, even when considering the deviation of the vitamin C retention percentage (%) of the LED, the lowest vitamin C retention rate (%) of the LED at each temperature is shown to be higher than the highest vitamin C retention rate (C) of C.

That is, it can be seen that the vitamin C of the strawberry stored according to the food storage method according to the present invention, which is an LED, is preserved more than that according to the conventional storage method.
