Detailed Implementation

[0017] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0018] Rice is mainly composed of starch and protein. Starch can be divided into rapidly digestible starch, slowly digestible starch, and resistant starch. For people with gastrointestinal discomfort or dental problems, rice with a high content of slowly digestible starch or resistant starch is not conducive to digestion.

[0019] Currently, most cooking appliances use high-power rapid heating to quickly raise the temperature from medium to high when cooking rice. While this method is quick, the resulting rice has poor starch digestibility. Therefore, this invention proposes a cooking appliance, its rice cooking control method, device, and storage medium to improve the digestibility of starch in rice.

[0020] The following description, with reference to the accompanying drawings, describes an embodiment of the cooking appliance and its rice cooking control method, apparatus, and storage medium. Here, the cooking appliance can be any appliance capable of cooking rice, such as a rice cooker or electric pressure cooker.

[0021] Figure 1 This is a flowchart of a rice cooking control method according to an embodiment of the present invention. Figure 1 As shown, the control method includes the following steps: Step S110: While the cooking appliance is cooking rice, obtain the cooking temperature of the cooking appliance.

[0022] Step S120: After detecting that the cooking temperature has reached the first preset temperature and has been kept warm for the first preset time, control the cooking appliance to perform a delayed heating action until the cooking temperature reaches the second preset temperature.

[0023] It should be noted that the second preset temperature is higher than the first preset temperature but lower than the boiling temperature (which can be 100℃); the first preset time can be set as needed, and this time maintains the temperature stable at the first preset temperature, which is intended to allow the rice to absorb water and expand.

[0024] Therefore, by controlling the cooking appliance to delay heating after the cooking temperature reaches the first preset temperature and is kept warm for the first preset time, the starch in the rice can fully absorb water and gelatinize. Furthermore, controlling the temperature below the second preset temperature can inhibit protein denaturation, thereby making the cooked rice soft, glutinous, and easy to digest, thus improving the digestibility of the rice.

[0025] The steps described above will be explained in detail below.

[0026] In step S110, when cooking rice in a cooking appliance, it is necessary to obtain the cooking temperature in the cooking appliance. The obtained cooking temperature can be used to determine the cooking stage of the rice, thereby enabling further control of the cooking appliance.

[0027] In some implementations, a temperature sensor can be used to obtain the cooking temperature in the cooking appliance. Specifically, a temperature sensor is installed in the cooking appliance (such as in the lid, bottom, etc.). The temperature sensor collects the cooking temperature in the cooking appliance in real time and uploads the cooking temperature to the control chip of the cooking appliance. The control chip then controls the cooking process of the rice based on the obtained cooking temperature.

[0028] Figure 2 This is a schematic diagram of the rice cooking process according to an embodiment of the present invention.

[0029] like Figure 2 As shown, in this embodiment of the invention, the cooking process of rice includes a heating and soaking stage, a heat preservation and soaking stage, a heating and gelatinization stage, a heat preservation and gelatinization stage, a heating and boiling stage, a heat preservation and boiling stage, a gelatinization stage, and a steaming and simmering stage.

[0030] Specifically, rice and water are placed in a cooking appliance in a ratio (e.g., rice:water = 1:1.2~1.3), and the appliance is heated to soak the rice, thus entering the heating and soaking stage; when the temperature rises to the first preset temperature... At that time, it enters the heat preservation and soaking stage, at the first preset temperature. First preset time for heat preservation This allows the rice to absorb water and expand; the first preset time for heat preservation. Then, the heating and gelatinization stage begins, and the cooking appliance is heated to raise the cooking temperature to the second preset temperature. At this stage, the rice begins to gelatinize; the cooking temperature rises to the second preset temperature. Then, it enters the heat preservation and gelatinization stage, at the second preset temperature. Second preset heat preservation time This allows the rice to continuously absorb water and gelatinize; the second preset heat preservation time... Then, it enters the heating and boiling stage, and the cooking appliance is heated again to raise the cooking temperature to the third preset temperature. Once the rice reaches a boiling point, it enters a heat preservation and boiling stage at the third preset temperature. Insulation third preset time This allows moisture in the cooking utensils to continuously evaporate; the third preset time for heat preservation. Then, the rice enters the gelatinization stage, where the cooking appliance is kept heated to evaporate the moisture and fully gelatinize the rice. After the rice is fully gelatinized, the rice enters the simmering stage, where the power of the cooking appliance is reduced to fully cook the rice, resulting in the final cooked rice.

[0031] When the cooking temperature reaches the first preset temperature And keep warm for the first preset time Afterwards (i.e., entering the heating and gelatinization stage), the rice begins to gelatinize. During this stage, the longer the rice absorbs water and gelatinizes, the more fully the starch in the rice will absorb water and gelatinize. Therefore, in this embodiment, when the cooking temperature is detected to have reached the first preset temperature... And the first preset time for heat preservation By controlling the cooking appliances to perform a delayed heating action, the rate of temperature rise during this stage is slowed down, allowing the starch to absorb water and gelatinize more fully, thereby improving the digestibility of the starch.

[0032] In some implementations, the first preset temperature The value range is 40-65℃, and the second preset temperature is... The value range is 80-95℃, and the duration for which the cooking appliance performs the delayed heating action is controlled is 5-10 minutes. For example, in some specific embodiments, the first preset temperature... It can be set to 45℃, 50℃, 55℃, 60℃, etc., with a second preset temperature. It can be 85℃, 90℃, etc.

[0033] In addition, the third preset temperature The boiling point of water (i.e., 100℃), the first preset time Second preset time and the third preset time The time can be 5 minutes, 8 minutes, 10 minutes, 12 minutes, 15 minutes, etc., and there are no specific restrictions here.

[0034] It is worth mentioning that the second preset temperature By controlling the cooking temperature during the gelatinization stage within the range of 80-95℃, the starch can be fully gelatinized while inhibiting protein denaturation, thereby suppressing the formation of starch-protein complexes and further improving starch digestibility. It should be noted that starch, through interaction with proteins, can increase its ordered structure, thus reducing its digestibility. Therefore, inhibiting the formation of starch-protein complexes can effectively improve starch digestibility.

[0035] In some implementations, controlling the cooking appliance to perform a delayed heating action in step S120 includes: reducing the heating power of the cooking appliance and increasing the cooking temperature linearly.

[0036] Specifically, during the heating and gelatinization stage of the cooking process, the heating power of the cooking appliance is reduced. As an example, typically, the heating power of the cooking appliance is between 500-700W during this stage. In this embodiment, the heating power can be reduced to between 300-500W. In some specific embodiments, the heating power for this stage can be set to 350W, 400W, 450W, etc. Because the heating power of the cooking appliance is reduced, the heating rate decreases, thereby slowing down the heating process during this stage, extending the heating time, and causing the cooking temperature to increase linearly.

[0037] In some embodiments, step S120, controlling the cooking appliance to perform a delayed heating action, includes: injecting liquid into the cooking appliance and linearly increasing the cooking temperature. It should be noted that the temperature of the injected liquid is lower than a first preset temperature. .

[0038] Specifically, during the heating and gelatinization stage of the cooking process, liquid is injected into the cooking appliance. This liquid can be cold water, room temperature water, or any other liquid with a temperature lower than the first preset temperature. The liquid. The temperature is below the first preset temperature. All liquids can lower the cooking temperature of cooking appliances, thus slowing down the heating process. It should be noted that when using this method to delay heating, the amount of water added should be reduced appropriately in the early stages of cooking, or excess water should be removed in the later stages of cooking to ensure that the amount of water in the cooking appliance is the amount required for cooking.

[0039] By injecting a lower-temperature liquid into the cooking appliance during the heating and gelatinization stage, the cooking temperature of the appliance during this process is reduced, thereby slowing down the heating process, extending the heating time, and causing the cooking temperature to increase linearly.

[0040] In some implementations, controlling the cooking appliance to perform a delayed heating action in step S120 includes: ventilating and dissipating heat from the cooking appliance and increasing the cooking temperature linearly.

[0041] Specifically, during the heating and gelatinization stage of the cooking process, cool or room-temperature air is blown into the cooking appliance at a certain speed, which can be 1-2 m / s. By blowing cool air into the cooking appliance at a certain speed, the airflow within the appliance is accelerated, carrying away some of the heat and promoting heat dissipation. This slows down the heating process during this stage, prolongs the heating time, and causes the cooking temperature to increase linearly.

[0042] Figure 3 This is a schematic diagram showing that the cooking temperature increases linearly during the heating and gelatinization stage of this invention.

[0043] like Figure 3 As shown, A represents the temperature curve of cooking temperature increase when the heating rate of the gelatinization stage is not slowed down; B represents the temperature curve of cooking temperature increase when the heating rate of the gelatinization stage is slowed down. The increase in cooking temperature can be linearly slowed down by reducing the heating power of the cooking appliance, injecting liquid into the cooking appliance, or ventilating the cooking appliance. Optionally, two or more of the above methods can be used simultaneously.

[0044] In some embodiments, controlling the cooking appliance to perform a delayed heating action in step S120 includes controlling the cooking appliance to heat intermittently so that the cooking temperature increases in a stepwise manner.

[0045] Specifically, during the gelatinization stage of the cooking process, the temperature in this stage is controlled by setting different temperature gradients. It should be noted that one or more temperature gradients can be set, and the specific number and temperature of the temperature gradients are not limited here.

[0046] Figure 4 This is a schematic diagram illustrating the stepwise increase in cooking temperature during the gelatinization stage of an example of the present invention.

[0047] See in this example. Figure 4 First preset temperature Set to 50℃, second preset temperature Set to 90℃. At the first preset temperature. Second preset temperature Two temperature gradients are set between the two temperatures: the first at 60°C and the second at 80°C. When the cooking process enters the gelatinization stage, the cooking appliance is first heated from 50°C to 60°C and held at 60°C for a period of time; then, it is heated from 60°C to 80°C and held at 80°C for a period of time; finally, it is heated from 80°C to 90°C. By controlling the intermittent heating of the cooking appliance and adding multiple holding periods, the heating time can be extended, thus slowing down the heating process and allowing the cooking temperature to increase in a stepwise manner.

[0048] By reducing the heating power of the cooking appliance, injecting liquid into the appliance, ventilating and dissipating heat, or controlling intermittent heating, the heating process can be slowed down. This delays the gelatinization stage, allowing the rice to absorb water and gelatinize more fully during this phase, thus improving starch digestibility. Simultaneously, the heating endpoint of the gelatinization stage (i.e., the second preset temperature) is also controlled. Maintaining the temperature at 80-95℃ can control protein denaturation, thereby inhibiting the formation of starch-protein complexes, promoting starch gelatinization, and improving starch digestibility.

[0049] Figure 5 This is a structural block diagram of the rice cooking control device according to the first embodiment of the present invention.

[0050] like Figure 5 As shown, the device includes: an acquisition module 510 for acquiring the cooking temperature in the cooking appliance; and a control module 520 for controlling the cooking appliance to perform a delayed heating action until the cooking temperature reaches a second preset temperature when the cooking temperature is detected to have reached a first preset temperature and been kept warm for a first preset time. The second preset temperature is greater than the first preset temperature but less than the boiling temperature.

[0051] Therefore, after the cooking temperature reaches the first preset temperature and is kept warm for the first preset time, the control module 520 controls the cooking appliance to perform a delayed heating action, thereby extending the heating time in this stage. As a result, the starch in the rice absorbs water and gelatinizes more fully, thereby improving the digestibility of the starch.

[0052] In some implementations, the acquisition module 510 can be a temperature sensor to collect the cooking temperature in the cooking appliance. The acquisition module 510 is connected to the control module 520, and the acquisition module 510 uploads the acquired cooking temperature to the control module 520.

[0053] The control module 520 controls the cooking appliance to sequentially execute the heating and soaking stage, the heat preservation and soaking stage, the heating and gelatinization stage, the heat preservation and gelatinization stage, the heating and boiling stage, the heat preservation and boiling stage, the gelatinization stage, and the simmering stage. After detecting that the cooking temperature uploaded by the acquisition module 510 has reached the first preset temperature and has been kept warm for the first preset time, the control module 520 controls the cooking appliance to perform a delayed heating action.

[0054] In some implementations, the first preset temperature ranges from 40 to 65°C, the second preset temperature ranges from 80 to 95°C, and the duration for which the cooking appliance performs the delayed heating action is 5 to 10 minutes.
