Fig. 2 is a schematic diagram of a refrigerator hardware configuration according to an exemplary embodiment of the present application, as an example, a refrigerator 200 may include a display 210, a controller 220, a memory 250, and several user input interfaces.

In some exemplary embodiments, the refrigerator 200 may further include at least one RFID detection module 230, a detector 240. The display 210, RFID detection module 230, detector 240, and memory 250 are coupled to the controller 220 via a communication interface. The display 210 is configured to receive an image signal output from the controller 220, perform a component for displaying video contents and images and a menu manipulation interface, and display a user manipulation UI interface for controlling the refrigerator 200.

The controller 220 may include one or more processing units, such as a system on a chip (SoC), a central processing unit (central processing unit, CPU), a Microcontroller (MCU), a memory controller, and the like. Wherein the different processing units may be separate devices or may be integrated in one or more processors.

Memory 250, which may include one or more memory units, may include, for example, volatile memory (volatile memory), such as: dynamic random access memory (dynamic random access memory, DRAM), static random access memory (static random access memory, SRAM), etc.; non-volatile memory (NVM) may also be included, such as: read-only memory (ROM), flash memory (flash memory), and the like. The different memory units may be separate devices or may be integrated or packaged in one or more processors or communication interfaces as part of the processors or communication interfaces.

The memory 250 stores program instructions and application programs such as voice applications. The controller 220 may call program instructions in the memory 250 or run an application program to cause the refrigerator to perform a related method, such as the food material information editing method provided in the embodiments of the present application.

The detector 240, including at least a sound collector, such as a microphone, may be used to receive the user's sound. Illustratively, a voice signal including a control instruction for a user to control the refrigerator 200.

Such as: the user can implement a user instruction input function through actions such as voice, touch, gesture, press and the like, and the input interface converts the received analog signals into digital signals and converts the digital signals into corresponding instruction signals to be sent to the refrigerator 200.

In some embodiments, the controller 220 may include a voice recognition module, which further includes a voice parsing unit and a voice command database, so that the refrigerator can independently perform voice recognition of voice data inputted by a user and a process of matching the recognized voice content with voice commands in the voice command database.

An RFID detection module 230 may be provided in each storage compartment for transmitting a wireless signal in the corresponding storage compartment and receiving a signal of an RFID tag in the storage compartment to obtain a food code of the RFID tag.

In some embodiments, the refrigerator further includes a tag reading area provided outside the storage compartment, i.e., an induction area for identifying the RFID tag, and an RFID detection module is provided at the tag reading area for detecting the RFID tag placed at the area. Alternatively, the tag reading area may be disposed below the display so that a user can simultaneously place (or remove) the RFID tag in the tag reading area and operate the user interface displayed by the display.

In some embodiments, the refrigerator may further include an RFID processing module connected to each RFID detection module, respectively, for controlling the RFID detection modules to transmit wireless signals and to receive signals of RFID tags fed back by the RFID detection modules.

In some embodiments, the RFID detection module may be specifically an antenna. The power of the antennas disposed in the different storage compartments may be different. And moreover, the power of the antenna of each storage room can ensure that the antenna can identify food materials contained in the room of the antenna, so that the false identification rate can be increased when the power is too high, and the food materials not contained in the room of the antenna can be identified when the power is too low. In a specific implementation, the power of the antenna may be determined in advance according to the space size of each storage chamber, and the power of each antenna may be set in the refrigerator, the larger the space, the larger the power.

In order to realize intelligent management of food materials, RFID tags are used for identifying the food materials in the storage room.

In some embodiments, by establishing a correspondence between the RFID tag and the food material information, virtual association between the RFID tag and the food material information is realized, and the same RFID tag can be sequentially corresponding to different food material information by modifying the correspondence between the RFID tag and the food material information, so that the flexibility of using the RFID tag is improved. For example, a corresponding relation between the identification information of the RFID tag and the food material information is established, and virtual association between the RFID tag and the food material is realized. The identification information of the RFID tag may be a tag code of the RFID tag identified by the RFID detection module 230, or may be a code segment in the tag code. In these embodiments, the controller 220 may determine food material information corresponding to each RFID tag according to the identification information of each RFID tag and the pre-established correspondence.

For example, the correspondence between the identification information of the RFID tag and the food information, which is established in advance, may be as follows:

RFID	food material information
Sign 1	Apple tree
Sign 2	Cucumber
Sign 3	Pork meat
……	……

After establishing the correspondence between the RFID tag and the food material information, the controller 220 obtains the tag code of the RFID tag by detecting the signal of the RFID tag, and can determine the food material information associated with each tag according to the tag code.

In some embodiments, the food material information associated with each tag is associated with one storage room, and the storage position of the food material can be determined according to the storage room associated with the food material information, for example, the food material information "apple" is associated with the "refrigerating room", and the apple can be determined to be stored in the refrigerating room.

In some embodiments, a food material management interface is displayed on the display 210, and a user manages food materials in the refrigerator by operating the food material management interface. For example, corresponding food material controls/icons are drawn in the food material management interface according to food material information associated with each RFID tag in the storage room, so that the food materials in the refrigerator are displayed in the form of icons, graphics, and the like. In addition, functional controls, such as RFID tag identification controls, food material adding controls, etc., may also be drawn in the food material management interface for user operation to trigger the controller 220 to implement the corresponding functions.

In some embodiments, the food management interface may include a plurality of food display areas, one food display area may correspond to each storage chamber, and food information associated with each storage chamber is displayed in the food display area corresponding to each storage chamber, that is, the food in the refrigerator is displayed in the food management interface in regions. For example, food material information associated with the refrigerating chamber is displayed in the food material display area corresponding to the refrigerating chamber. The food material information displayed in the food material management interface includes, but is not limited to, a food material icon, a food material name, and a freshness identifier of the food material, wherein the food material icon may be generated according to pictographic pictures of the food material, and the freshness identifier of the food material is used to show any one or more of an in-put time, a remaining time from expiration, and an expiration time of the food material. It should be appreciated that the food material name, freshness identification of the food material, etc. may be part of the food material icon, i.e. contained in the food material icon.

Fig. 3 is a user interface, specifically an exemplary food material management interface, according to an exemplary embodiment of the present application. Referring to fig. 3, the food management interface includes a label editing control 301, a recommended menu control 302, an add food control 306, and partitions corresponding to each storage room, such as a partition 303 corresponding to a refrigerating room, a partition 304 corresponding to a temperature changing room, and a partition 305 corresponding to a cooling room. Each of the partitions displays a food material icon corresponding to each food material in the storage compartment, such as food material 1, food material 2, food material 3, food material 4, and food material 5 in partition 303, food material icon 6-food material icon 11 in partition 304, and food material icon 12 and food material icon 13 in partition 305. In addition, each of the sections has one scrollable scroll bar, such as scrollbar 3030 scrollable up and down in section 303, scrollbar 3040 scrollable up and down in section 304, scrollbar 3050 scrollable up and down in section 305, and the user can scroll up or down the view displayed in the section by operating the scrollbar to display food icons not all shown on the user interface.

With continued reference to fig. 3, each food material icon includes a food material picture, a food material name, and a freshness identification of the food material. Taking food material 3[3031] as an example, it includes food material picture 30311, food material name "food material 1" (30312), and freshness indicator 30313. Note that in fig. 3, since the food material 1 has expired, the stamp mark having the "expired" character is displayed on the food material picture as the freshness mark of the food material 1, so that the user can quickly notice the food material that has expired in the refrigerator.

In some embodiments, a particular number of days remaining is explicitly indicated by the freshness indicator when the number of days remaining for the expiration of the food distance is less than a preset number of days. For example, in the food management interface shown in fig. 3, since the number of days remaining until the food 6[3041] expires is smaller than the preset number of days, the freshness identifier [304111] of the food 4 includes a text prompt of "remaining 2 days", so that the user can quickly obtain the number of days remaining until the food is about to expire.

In a specific implementation, the food management interface may be an interface of a food management related application that is run by the controller 220, and the user may trigger to display the food management interface on the food management related application. When the food material management related application receives user operation triggering the display of the food material management interface, the food material information set is read from the memory, and corresponding food material icons are displayed in the food material management interface according to the food material information in the food material information set. The food material information set is a set formed by food material information corresponding to all RFID tags in the current storage room.

In some embodiments, the tag encoding of the RFID tag may include one or more code segments.

In some embodiments, the tag code of the RFID tag includes a plurality of code segments that conform to a preset composition rule, and after the tag code is obtained, the controller intercepts the code segment corresponding to the tag identifier according to the preset composition rule to obtain the unique identifier of the tag, that is, the tag identifier. One code segment in the label code is used as the label identification of the RFID label, and the efficiency of the identification comparison process can be improved due to the fact that the identification length is shortened.

In some embodiments, RFID tags may be classified into custom tags, which refer to tags whose associated food names may be customized by a user, and predefined tags, which refer to tags whose associated food names may not be customized by a user. Custom tags and predefined tags may be distinguished according to tag coding.

In some embodiments, the tag code of the RFID tag includes at least two code segments, a first code segment and a second code segment, respectively. Wherein the first code segment is used to write a first code, which may be a predetermined code or a non-predetermined code. For the RFID tag with the first code being the preset code, the corresponding food material information can be customized by a user, namely the customized tag; for the RFID tag with the first code being the non-preset code, the corresponding preset food material information is pre-stored in the cloud server or the local food material library, and cannot be customized by a user, namely the RFID tag is a predefined tag. The second code segment is used to write a second code that is unique identification information of the RFID tag. It should be noted that, the user-defined food material name means that the user can associate any food material name with the RFID tag according to the requirement, and at the same time, the user can also change the defined tag according to the change of the requirement, so that the same tag is associated with different food material names, and the user-defined food material name means that the user cannot change the food material name associated with the RFID tag, and the food material name associated with the RFID tag is predefined and stored in the cloud server or the local food material library.

When an RFID tag is given, whether the tag is a predefined tag or a custom tag may be determined based on a first code included in the tag code. If the first code is a predetermined code, the tag is a custom tag, and if the first code is not a predetermined code, the tag is a predefined tag. In some embodiments, at least two code segments included in the tag code of the RFID tag conform to a preset composition rule, and after the tag code is acquired, the controller intercepts the first code segment and/or the second code segment according to the preset composition rule to acquire the first code and/or the second code, thereby saving the process of analyzing the long code information and improving the processing efficiency.

In some embodiments, the predetermined code has uniqueness, such as 00; the non-predetermined code does not have uniqueness, and may have a plurality of codes, and one non-predetermined code corresponds to one food material information.

Illustratively, a tag encoding structure for an RFID tag is as follows:

for example, when the controller obtains the tag code of the RFID tag as "01123456789012345678901234", the controller may intercept the first code as "01" and intercept the second code as "123456789012345678901234" according to a preset composition rule.

It should be noted that, according to different requirements, the tag code of the RFID tag may further include more code segments, such as a third code segment, for writing the manufacturer identifier of the RFID tag, and further, such as a fourth code segment, for serving as a reserved bit of the tag code, so as to improve the scalability of the RFID tag. In other embodiments, the manufacturer identification of the RFID tag may also be included in the second code segment, which is not described herein.

Illustratively, the correspondence between the first code (non-predetermined code) and the food material information may be as follows:

RFID first encoding	Food material name
01	Radish
02	Carrot (carrot)
03	Lotus root
……	……

In some embodiments, when the food material management interface is displayed on the display, the user may input an instruction indicating to edit food material information by operating the food material management interface, for example, the user clicks a food material information editing control provided by the food material management interface to indicate to edit food material information; after the controller receives the instruction, the controller starts to detect the signal of the RFID tag placed on the tag reading area to acquire the identification information of the RFID tag, displays an interface for editing food material information associated with the RFID tag, namely an instant food material editing interface, and inputs food material information associated with the RFID tag in the food material editing interface.

In some embodiments, the obtained identification information of the RFID tag can be displayed in the food editing interface, so that a user can intuitively see the identification information of the RFID tag, and the user does not need to manually input the identification information, thereby improving user experience.

In some embodiments, at least one food material editing item is displayed in the food material editing interface, each food material editing item including an item name and an item content, wherein the item content is a portion to be edited, and the user may input food material information for association with the RFID tag by inputting the item content of each food material editing item at the input location. After the input is completed, the controller correspondingly stores the input food material information and the identification information, so that the establishment of a corresponding relation table of the identification information and the food material information of the RFID tag is completed and perfected.

In some embodiments, the interface for editing the food material information may be referred to as a food material editing interface, and the food material editing items displayed thereon may include a food material name editing item, a food material shelf life editing item, a food material quantity editing item, and the like. It should be understood that the item name of the food material name editing item may be a "tag name", the item content may be a food material name to be input or updated, the item name of the food material shelf life editing item may be a "shelf life", the item content may be a shelf life to be input or updated, the item name of the food material quantity editing item may be a "quantity", and the item content may be a quantity to be selected or changed.

As shown in fig. 3, the user may click on the RFID tag editing control in the interface to input an instruction indicating that food information editing is to be performed. In response to the instruction, the controller controls the RFID detection module to start detecting the signal of the RFID tag on the tag reading area to acquire the identification information of the RFID tag. After the controller acquires the identification information of the RFID tag, a food editing interface is presented on the display.

In some embodiments, after receiving an instruction input by a user and indicating food material information editing, the controller responds to the instruction to display a label scanning interface, displays a scanning prompt in the label scanning interface, and prompts the user to place an RFID label to be edited on a label reading area by displaying the scanning prompt. Meanwhile, the controller controls the RFID detection module to start detecting signals of the RFID tag on the tag reading area to acquire identification information of the RFID tag. After the controller acquires the identification information of the RFID tag, a food editing interface is presented on the display.

In some embodiments, the user may also instruct to edit the food material information by speaking a preset voice password. For example, the user speaks: "Label editing". When voice data input by a user is received and the content is identified as label editing, confirming that an input preset voice instruction for triggering food material information corresponding to the RFID label to be edited is received. At this time, the controller displays a tag scanning interface in response to the instruction, and starts detecting the RFID tag on the tag reading area.

In some embodiments, when an input preset voice command is received, firstly, judging whether an RFID tag on a tag reading area is detected, if the RFID tag on the tag reading area is not detected, indicating that the user has not placed the RFID tag to be edited on the tag reading area, at this time, displaying a tag scanning interface including a scanning prompt to prompt the user to place the RFID tag to be edited on the tag reading area.

In some embodiments, the above-described instruction for instructing food material information editing is also referred to as an RFID tag editing instruction.

In some embodiments, the database includes a food material library, where the food material library includes a large amount of food material information, such as preset food material information corresponding to each predefined tag and food material information associated with each defined tag, where each piece of food material information is associated with a storage room, and where the preset food material information corresponding to each predefined tag is further associated with a tag code of the predefined tag, so that corresponding preset food material information can be found in the food material library according to the tag code of the predefined tag, and the food material information corresponding to each defined tag is further associated with a tag code of the custom tag, so that associated food material information can be found in the food material library according to the tag code of the custom tag.

In some embodiments, the user may also autonomously define food material information that does not exist in the cloud server to expand the food material library.

In some embodiments, the preset food material information in the food material library may be stored in the food material library in a classified manner, for example, the food material information of the fruit food material is stored in one fruit food material set, the food material information of the vegetable food material is stored in another vegetable food material set, the user-defined food material information is stored in the user-defined food material set, and all the food material information in the food material library forms a food material complete set. And various food material information is displayed in a food material warehouse in a classified manner. For example, an operation control corresponding to each food material category may be set in the food material library interface, when the user clicks the fruit control, a food material icon corresponding to each piece of food material information in the fruit food material set is displayed, when the user clicks the vegetable control, a food material icon corresponding to each piece of food material information in the vegetable food material set is displayed, and when the user clicks the custom food material control, a food material icon corresponding to each piece of food material information in the custom food material set is displayed.

In some embodiments, the food material library is intuitively displayed to the user by displaying the food material icons corresponding to part or all of the food material information in the user interface, so that the user can conveniently view the food material library.

Fig. 4 is a food material library interface as shown in some exemplary embodiments of the present application. As shown in fig. 4, the food material library interface includes a label switching field 410 and a content area 420, the label switching field 410 includes a plurality of label controls, which are "all" 411, "fruit" 412, "vegetable" 413, "meat" 414, "drink" 415, "aquatic" 416, "other" 417 and "custom food material" 418, respectively, where the focus is on "all" 411, i.e., "all" 411 is in a selected state, so that the content area 420 displays food material icons corresponding to "all".

In combination with the above embodiments, in other embodiments, the food material library interface further comprises a search bar comprising a search term input box and a search control. The user can input a search word, such as a food material name, in the search word input box, and after inputting the search word, the user can input a food material search instruction carrying the search word by clicking a search control, wherein the food material search instruction instructs a food material management application to search for food materials matched with the input search word from a food material library, and displays a food material icon of the matched food materials. Therefore, the user does not need to search for the food icons to be selected by browsing a large number of selectable food icons, so that the time of the user is saved, and the user experience is improved.

The food material management application responds to the input food material search instruction, and matches search words carried by the instruction with food materials in the food material warehouse. If the target food materials matched with the search word exist in the food material library, displaying a search result interface of the food material icons containing the target food materials; if the target food materials matched with the search word do not exist in the food material library, a custom food material adding control is popped up, the custom food material adding control is used for triggering to jump to a custom food material adding interface, and the custom food material adding interface is used for receiving custom food materials input by a user.

Compared with the traditional food material searching method, the food material management application fuses the food material searching function and the custom food material adding function, and if target food materials matched with the search word exist in the food material library, a search result interface of the food material icon containing the target food materials is directly displayed. If no target food matched with the search word exists in the food library, the user does not need to exit the food search interface and enter the custom food adding interface except prompting that no corresponding food exists. But can directly pop out the custom food material adding control at the interface when the target food materials matched with the search word do not exist in the food material library, so as to guide the user to add the unsearched food materials to the food material library.

Fig. 9 is another food material library interface shown in some exemplary embodiments of the present application. As shown in fig. 9, on the basis of the food material library interface shown in fig. 4, a search field 910 including a search term input box 911 and a search control 912 is displayed above the tab switch field. In some implementations, the user activates the initial input location by clicking on the search term input box, the food management application activates the initial input location in response to the user clicking on the search term input box, and an input method keyboard is displayed above a lower portion of the food library interface. In this way, the user can enter search terms based on the input method keyboard. After the input is completed, the user inputs a food material search instruction carrying the input search word by clicking the search control. In other implementations, the user may enter the search term by speaking a voice password, such as the user speaking "search apple. The food material management application receives the voice password input by the user through a detector (microphone), and recognizes a food material search instruction carrying a search word through semantic analysis.

It should be noted that, when other interfaces are displayed, the user may also input the food material search instruction by operating the corresponding controls on the other interfaces, or when other interfaces are displayed, input the food material search instruction based on the voice control function by speaking the voice password. For example, in some embodiments, a food material search control is displayed in the food material management interface. When a user clicks a food material search control, the food material management application responds to the operation of the user on the control, and displays a search interface, wherein the search interface at least comprises a search bar, and the search bar comprises a search word input box and a search control. The user can input search words, such as food material names, in the search word input box, and after inputting the search words, the user can input food material search instructions carrying the search words by clicking a search control. Historical search terms may also be included in the search interface.

FIG. 10 is a search interface as illustrated in some example embodiments herein. As shown in fig. 10, the search interface searches the column 110 and the content area 120. The search bar 110 includes a search term input box 111 and a search control 112, with a plurality of historical search terms displayed in a content area 120.

In some implementations, after responding to an input food material search instruction carrying a search word, the food material management application traverses food material information corresponding to each food material in the food material library, and matches the food material name in the traversed food material information with the search word by using a preset text matching rule. The preset text matching rules comprise matching rules based on regular expressions, text matching rules based on semantic similarity and the like, and the text matching rules are not limited in the application. For example, if the food material name includes a search term, the food material name matches the search term. For another example, if the semantic similarity between the food name and the search term is greater than a preset threshold, the food name is matched with the search term. If at least one food material name matched with the search word is traversed, determining a food material corresponding to the food material name as a target food material; if the food material names matched with the search words are not traversed, determining that target food materials matched with the search words do not exist in the food material library.

In some implementations, the search result variable is included in the local data corresponding to the food management application. In the traversing and matching process, each time a target food material matched with the search word is traversed, food material information corresponding to the target food material is added into a search result variable; after the matching is finished, a search result interface containing the food material icons of the target food materials is displayed according to the food material information in the search result variables.

Fig. 11 is a search results interface, shown in some exemplary embodiments of the present application, that may specifically be an interface displayed by a user after searching for "apples" in the food material library interface shown in fig. 9. As shown in fig. 11, the search results interface displays thereon icons of food materials matching "apples", including "apples", "applesauce", "apple juice", "apple fructose" and "cider vinegar". It can be seen that, based on the search function introduced in the foregoing embodiment, the range of selectable food materials can be greatly reduced, the process of browsing icons and searching targets personally by a user is avoided, the time of the user is saved, and the use experience is improved.

FIG. 12 is a search results interface, particularly a search results interface displayed when there is no target food material in the food material library that matches the search term, as shown in some example embodiments of the present application. For example, fig. 12 may be an interface displayed after a user searches for "tiramisu" in a food material library interface in the absence of "tiramisu" in the food material library. As shown in fig. 12, the search result interface displays a custom food addition control "+add custom food". When the user operates the control, a custom food adding interface will be displayed, as shown in fig. 7.

In some embodiments, the food management application responds to the user operation of the custom food adding control displayed in the search interface, firstly returns to the food library interface when the custom category control is selected, then displays a custom food adding frame on the food library interface when the custom category control is selected, and displays search words input by the user in an input area corresponding to the food name definition item in the custom food adding frame. Because the search word input by the user represents the food materials which are not searched in the food material library by the user, namely the user-defined food materials which the user wants to add can also be represented, the process of manually inputting the food material names by the user can be saved by displaying the search word in the input area corresponding to the food material name definition items, and the user experience is improved.

Illustratively, when the user operates the custom food material addition control "+add custom food material" in fig. 12, the user automatically returns to the food material library interface when the custom category control is selected as shown in fig. 6, and a custom food material addition frame is displayed at the upper layer of the food material library interface, and "tiramisu" is displayed in the input area corresponding to the food material name definition item in the custom food material addition frame, that is, as shown in fig. 13. Therefore, the user does not need to manually input 'tiramisu', the user operation is saved, and the user experience is improved.

It is noted that when there is no food in the food warehouse that the user wants to add, a demand for adding custom food is generated. Based on the foregoing embodiment, it can be seen that, in the case that there is no target food matching the search term in the food library, by setting the custom food adding control in the search result interface, the user can trigger and display the custom food adding interface by one key, so as to avoid a series of operations of returning control to the food library interface corresponding to the "custom food" label control, realize a function of quickly entering the custom food adding interface when there is no search result, and quickly satisfy the requirement of the user for adding custom food. By displaying the search word in the input area corresponding to the food material name definition item, the process of manually inputting the food material name by the user can be saved, and therefore user experience is improved.

In particular, a search listening service (msearhlistener) is set in an interface including a search bar to listen to a search word input by a user in a search word input box and an operation of a search control through the search listening service. For example, a search listening service is set up at the food material library interface. Under the condition of no search result, the food management application responds to the operation of a user on a custom food adding control in a search result interface, and the search word monitored by the search monitoring service is recalled into the page parameter corresponding to the food library interface through a callback function (addclumsfood). The callback function is also used for switching the state corresponding to the custom food material control in the food material library interface into a selected state so as to display the food material library interface when the custom food material control is selected, controlling the custom food material adding frame to be ejected, and filling the callback search word in the input area corresponding to the food material name definition item.

In some embodiments, when displaying the food material library interface or displaying the search result interface of the food material icon containing the target food material, the user may select the food material icon in the interface through a single-point or long-press operation, and when the user selects a certain food material icon, the food material icon is displayed in a selected state. The user can select a plurality of food icons through a plurality of operations. The food material management application responds to the selection operation of the user on the food material icon, updates the display state of the food material icon selected by the user into a selected state, and if the selected operation is the first selected operation input by the user, displays a preview area at the position where the food material icon is not blocked in the current interface, and displays the food material icon selected by the user in the preview area. And the food material management application responds to the input instruction to complete the selection operation, and stores the food material information corresponding to the food material icon selected by the user in the local food material information set.

For example, when a search result interface as shown in fig. 11 is displayed, the food management application updates the display state of the "apple" icon to the selected state in response to a user's selection operation of "apple", and displays a preview area 141 as shown in fig. 14 on the lower side of the search result interface, in which the "apple" icon is displayed. When the user continues to select "cider", the "apple" icon will assume the selected state, and at the same time, the "cider" icon will also be displayed in the preview area 141. It can be seen that preview area 141 also displays a "selected" control. After the user finishes selecting, by clicking the "selected" control, inputting an operation indicating that the selection is finished, and the food management application responds to the operation to store the food information corresponding to the food icon selected by the user in the local food information set and marks the food information as a put-in state.
